Error 1045 28000 access denied for user username localhost using password yes

I have been following a manual to install a software suite on Ubuntu. I have no knowledge of MySQL at all. I have done the following installations on my Ubuntu. sudo apt-get update sudo apt-get ins...

Note: For MySQL 5.7+, please see the answer from Lahiru to this question. That contains more current information.

For MySQL < 5.7:

The default root password is blank (i.e., an empty string), not root. So you can just log in as:

mysql -u root

You should obviously change your root password after installation:

mysqladmin -u root password [newpassword]

In most cases you should also set up individual user accounts before working extensively with the database as well.

I was able to solve this problem by executing this statement

sudo dpkg-reconfigure mysql-server-5.5

Which will change the root password.

I was recently faced with the same problem, but in my case, I remember my password quite alright, but it kept on giving me the same error. I tried so many solutions, but still none helped. Then I tried this:

mysql -u root -p

After which it asks you for a password like this

Enter password:

And then I typed in the password I used. That’s all.

You have to reset the password! Steps for Mac OS X (tested and working) and Ubuntu:

Stop MySQL using

sudo service mysql stop

or

sudo /usr/local/mysql/support-files/mysql.server stop

Start it in safe mode:

sudo mysqld_safe --skip-grant-tables --skip-networking

(the above line is the whole command)

This will be an ongoing command until the process is finished, so open another shell/terminal window, log in without a password:

mysql -u root

mysql> UPDATE mysql.user SET Password=PASSWORD('password') WHERE User='root';

As per @IberoMedia’s comment, for newer versions of MySQL, the field is called authentication_string:

mysql> UPDATE mysql.user SET authentication_string =PASSWORD('password') WHERE User='root';

Start MySQL using:

sudo service mysql start

or

sudo /usr/local/mysql/support-files/mysql.server start

Your new password is ‘password’.

Note: for version of MySQL > 5.7 try this:

update mysql.user set authentication_string='password' where user='root';

It happens when your password is missing.

Steps to change the password when you have forgotten it:

  1. Stop MySQL Server (on Linux):

    sudo systemctl stop mysql
    
  2. Start the database without loading the grant tables or enabling networking:

    sudo mysqld_safe --skip-grant-tables --skip-networking &
    

    The ampersand at the end of this command will make this process run in the background, so you can continue to use your terminal and run mysql -u root (as root). It will not ask for a password.

    If you get error like as below:

    2018-02-12T08:57:39.826071Z mysqld_safe Directory '/var/run/mysqld' for UNIX
    socket file don't exists.
    mysql -u root
    ERROR 2002 (HY000): Can't connect to local MySQL server through socket
    '/var/run/mysqld/mysqld.sock' (2)
    [1]+  Exit 1
    
  3. Make MySQL service directory.

    sudo mkdir /var/run/mysqld
    

    Give MySQL user permission to write to the service directory.

    sudo chown mysql: /var/run/mysqld
    
  4. Run the same command in step 2 to run MySQL in background.

  5. Run mysql -u root. You will get the MySQL console without entering a password.

    Run these commands

    FLUSH PRIVILEGES;
    

    For MySQL 5.7.6 and newer

    ALTER USER 'root'@'localhost' IDENTIFIED BY 'new_password';
    

    For MySQL 5.7.5 and older

    SET PASSWORD FOR 'root'@'localhost' = PASSWORD('new_password');
    

    If the ALTER USER command doesn’t work use:

    UPDATE mysql.user SET authentication_string = PASSWORD('new_password')     WHERE User = 'root' AND Host = 'localhost';
    

    Now exit

  6. To stop the instance started manually:

    sudo kill `cat /var/run/mysqld/mysqld.pid`
    
  7. Restart MySQL

    sudo systemctl start mysql

At the initial start up of the server the following happens, given that the data directory of the server is empty:

  • The server is initialized.
  • SSL certificate and key files are generated in the data directory.
  • The validate_password plugin is installed and enabled.
  • The superuser account ‘root’@’localhost’ is created. The password for the superuser is set and stored in the error log file.

To reveal it, use the following command:

shell> sudo grep 'temporary password' /var/log/mysqld.log

Change the root password as soon as possible by logging in with the generated temporary password and set a custom password for the superuser account:

shell> mysql -u root -p

mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass5!';

If the problem still exists, try to force changing the password:

/etc/init.d/mysql stop

mysqld_safe --skip-grant-tables &

mysql -u root

Set up a new MySQL root user password:

use mysql;
update user set password=PASSWORD("NEW-ROOT-PASSWORD") where User='root';
flush privileges;
quit;

Stop the MySQL server:

/etc/init.d/mysql stop

Start the MySQL server and test it:

mysql -u root -p

If none of the other answers work for you, and you received this error:

mysqld_safe Logging to '/var/log/mysql/error.log'.
mysqld_safe Directory '/var/run/mysqld' for UNIX socket file don't exists.
[1]+  Exit 1                  sudo mysqld_safe --skip-grant-tables

Follow the below commands step by step until you reset your password:

# Stop your server first
sudo service mysql stop

# Make the MySQL service directory.
sudo mkdir /var/run/mysqld

# Give MySQL permission to work with the created directory
sudo chown mysql: /var/run/mysqld

# Start MySQL, without permission and network checking
sudo mysqld_safe --skip-grant-tables --skip-networking &

# Log in to your server without any password.
mysql -u root mysql


# Update the password for the root user:
UPDATE mysql.user SET authentication_string=PASSWORD('YourNewPasswordBuddy'), plugin='mysql_native_password' WHERE User='root' AND Host='localhost';

# If you omit (AND Host='localhost') section, it updates
# the root password regardless of its host

FLUSH PRIVILEGES;
EXIT;

# Kill the mysqld_safe process
sudo service mysql restart

# Now you can use your new password to log in to your server
mysql -u root -p

# Take note for remote access. You should create a remote
# user and then grant all privileges to that remote user

I came across this very annoying problem and found many answers that did not work. The best solution I came across was to completely uninstall MySQL and reinstall it. On reinstall you set a root password and this fixed the problem.

sudo apt-get purge mysql-server mysql-client mysql-common mysql-server-core-5.5 mysql-client-core-5.5
sudo rm -rf /etc/mysql /var/lib/mysql
sudo apt-get autoremove
sudo apt-get autoclean

I found this code elsewhere, so I don’t take any credit for it. But it works. To install MySQL after uninstalling it, I think DigitalOcean has a good tutorial on it. Checkout my gist for this.

I am using Ubuntu 16.04 (Xenial Xerus) and installed MySQL 5.7.

I had the same issue

Login denied for root user.

I tried the below steps:

  1. dpkg --get-selections | grep mysql (to get the version of MySQL).

  2. dpkg-reconfigure mysql-server-5.7

  3. mysql -u root -p

Without -p that doesn’t prompt you to ask password. Once you are in, you can create a user with a password by following steps:

CREATE USER 'your_new_username'@'your-hostname' IDENTIFIED BY 'your-password';

GRANT ALL PRIVILEGES ON *.* to 'your_new_username'@'your-hostname' WITH GRANT OPTION;

Exit from the root and log in from the <name> you gave above.

mysql -u <your_new_username> -p

For some reason still just typing MySQL does not work. At all. I suggest to make it a habit to use mysql -u <name> -p.

I installed MySQL as root user ($SUDO) and got this same issue

Here is how I fixed it:

  1. sudo cat /etc/mysql/debian.cnf

    This will show details as:

    # Automatically generated for Debian scripts. DO NOT TOUCH! [client] host = localhost user = debian-sys-maint password = GUx0RblkD3sPhHL5 socket = /var/run/mysqld/mysqld.sock [mysql_upgrade] host = localhost user = debian-sys-maint password = GUx0RblkD3sPhHL5 socket = /var/run/mysqld/mysqld.sock

    Above we can see the password. But we are just going to use(GUx0RblkD3sPhHL5) that in the prompt.

  2. `mysql -u debian-sys-maint -p

    Enter password: `

    Now provide the password (GUx0RblkD3sPhHL5).

  3. Now exit from MySQL and log in again as:

    `mysql -u root -p

    Enter password: `

Now provide the new password. That’s all. We have a new password for further uses.

It worked for me.

For those for whom the current answers didn’t work can try this (tested on macOS):

mysql -h localhost -u root -p --protocol=TCP

After this, a password will be asked from you and you should use your OS user password. Then when you get into MySQL you can run:

select Host, User from mysql.user;

And you should see:

MySQL [(none)]> select Host, User from mysql.user;
+-----------+------------------+
| Host      | User             |
+-----------+------------------+
| localhost | mysql.infoschema |
| localhost | mysql.session    |
| localhost | mysql.sys        |
| localhost | root             |
+-----------+------------------+

And from here you can change the configurations and edit the password or modify the grants.

I am using mysql-5.7.12-osx10.11-x86_64.dmg on Mac OS X.

The installation process automatically sets up a temporary password for the root user. You should save the password. The password can not be recovered.

Follow the instructions:

  1. Go to cd /usr/local/mysql/bin/
  2. Enter the temporary password (which would look something like, «tsO07JF1=>3»)
  3. You should get the mysql> prompt.
  4. Run, SET PASSWORD FOR 'root'@'localhost' = PASSWORD('{YOUR_PASSWORD}'); If you wish to set your password: «root» then the command would be, SET PASSWORD FOR 'root'@'localhost' = PASSWORD('root');
  5. Run ALTER USER 'root'@'localhost' PASSWORD EXPIRE NEVER;
  6. Run exit
  7. Run ./mysql -u root -p
  8. Type your password. In my case I would type, «root» (without quote)
  9. That’s all.

For convenience, you should add "/usr/local/mysql/bin" to your PATH environment variable.

Now from anywhere you can type ./mysql -u root -p and then type the password and you will get the mysql> prompt.

The answer may sound silly, but after wasting hours of time, this is how I got it to work:

mysql -u root -p

I got the error message

ERROR 1045 (28000): Access denied for user ‘root’@’localhost’ (using password: YES)

Even though I was typing the correct password (the temporary password you get when you first install MySQL).

I got it right when I typed in the password when the password prompt was blinking.

If you have MySQL as part of a Docker image (say on port 6606) and an Ubuntu install (on port 3306) specifying the port is not enough:

mysql -u root -p -P 6606

will throw:

ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

as it’s trying to connect to localhost by default, specifying your local IP address fixes the issue:

mysql -u root -p -P 6606 -h 127.0.0.1

Year 2021.

Answer for Ubuntu 20.04 (Focal Fossa) (maybe other distributions as well).

After days of wandering around… and having none of those answers working for me, I did this and it worked!

Always in a Bash shell:

sudo systemctl disable mysql

In order to stop the daemon from starting on boot.

sudo apt purge mysql-server

and

sudo apt purge mysql-community-server*

There, it warns you you’ll erase configuration files… so it’s working! Because those are the ones making trouble!

sudo autoremove

To delete all the left behind packages.

Then (maybe it’s optional, but I did it) reboot.
Also, I downloaded mysql-server-8.0 from the official MySQL webpage:

sudo apt install mysql-server

A signal that it’s working is that when you enter the command above, the system asks you to enter the root password.

Finally:

mysql -u root -p

And the password you entered before.

I also came across the same problem. I did:

  2. Navigate to C:Program FilesMySQLMySQL Server 8.0bin>
    (where MySQL Server 8.0 may be different depending on the server you installed)

  3. Then put the following command mysql -u root -p

  4. It will prompt for the password… simply hit Enter, as sometimes the password you entered while installing is changed by to blank.

Now you can simply access the database.

This solution worked for me on the Windows platform.

In Ubuntu 16.04 (Xenial Xerus) and MySQL version 5.7.13, I was able to resolve the problem with the steps below:

  1. Follow the instructions from section B.5.3.2.2 Resetting the Root Password: Unix and Unix-Like Systems
    MySQL 5.7 reference manual

  2. When I tried #sudo mysqld_safe --init-file=/home/me/mysql-init & it failed. The error was in /var/log/mysql/error.log:

    2016-08-10T11:41:20.421946Z 0 [Note] Execution of init_file '/home/me/mysql/mysql-init' started.

    2016-08-10T11:41:20.422096Z 0 [ERROR] Aborting
    

The file permission of mysql-init was not the problem. We need to edit AppArmor permissions.

  1. Edit by sudo vi /etc/apparmor.d/usr.sbin.mysqld

     ....
       /var/log/mysql/ r,
       /var/log/mysql/** rw,
    
    
     # Allow user init file
       /home/pranab/mysql/* r,
    
       # Site-specific additions and overrides. See local/README for details.
       #include <local/usr.sbin.mysqld>
     }
    
  2. Do sudo /etc/init.d/apparmor reload

  3. Start mysqld_safe again. Try step 2 above. Check file /var/log/mysql/error.log. Make sure there is no error and the mysqld is successfully started.

  4. Run mysql -u root -p

    Enter password:

    Enter the password that you specified in mysql-init. You should be able to log in as root now.

  5. Shutdown mysqld_safe by sudo mysqladmin -u root -p shutdown

  6. Start mysqld the normal way by sudo systemctl start mysql

While the top answer (with mysqladmin) worked on macOS v10.15 (Catalina), it did not work on Ubuntu. Then I tried many of the other options, including a safe start for MySQL, but none worked.

Here is one that does:

At least for the version I got 5.7.28-0ubuntu0.18.04.4 answers were lacking IDENTIFIED WITH mysql_native_password. 5.7.28 is the default on the current LTS and thus should be the default for most new new systems (till Ubuntu 20.04 (Focal Fossa) LTS comes out).

The error that I faced was:

It was a problem with the port running on.

By default, MySQL is running on port 3306.

You can check that on by running

  • in a 32-bit system:

    sudo /opt/lampp/manager-linux.run

  • in a 64-bit system:

    sudo /opt/lampp/manager-linux-x64.run

and click on the Configure button.

In recent MySQL versions there isn’t any password in the mysql.user table.

So you need to execute ALTER USER. Put this one line command into the file.

ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass';

And execute it as an init file (as the root or mysql user):

mysqld_safe --init-file=/home/me/mysql-init &

MySQL server need to be stopped to start mysqld_safe.

Also, there may be a problem with AppArmor permissions to load this init file. Read more in AppArmor and MySQL.

On Mac, if you have a problem in logging in with the first password you were given in installation, maybe you can just simply kill the MySQL process and then try.

So:

  1. run the following command to find the PID of MySQL:

    ps -aef | grep mysql | grep -v grep
    
  2. kill the process:

    kill -15 [process id]
    

Then you can log in with the initial password using this command:

mysql -uroot -p

Which asks you to enter your password. Just enter the initial password.

Автор: Василий Лукьянчиков , vl (at) sqlinfo (dot) ru

Статистика форума SQLinfo показывает, что одной из наиболее популярных проблем является ошибка mysql №1045 (ошибка доступа).
Текст ошибки содержит имя пользователя, которому отказано в доступе, компьютер, с которого производилось подключение, а также ключевое слово YES или NO, которые показывают использовался ли при этом пароль или была попытка выполнить подключение с пустым паролем.

Типичные примеры:

ERROR 1045 (28000): Access denied for user ‘root’@‘localhost’ (using password: YES) — сервер MySQL
— сообщает, что была неудачная попытка подключения с локальной машины пользователя с именем root и
— не пустым паролем.

ERROR 1045 (28000): Access denied for user ‘root’@‘localhost’ (using password: NO) — отказано в
— доступе с локальной машины пользователю с именем root при попытке подключения с пустым паролем.

ERROR 1045 (28000): Access denied for user ‘ODBC’@‘localhost’ (using password: NO) — отказано в
— доступе с локальной машины пользователю с именем ODBC при попытке подключения с пустым паролем.

Причина возникновения ошибки 1045

Как ни банально, но единственная причина это неправильная комбинация пользователя и пароля. Обратите внимание, речь идет о комбинации пользователь и пароль, а не имя пользователя и пароль. Это очень важный момент, так как в MySQL пользователь характеризуется двумя параметрами: именем и хостом, с которого он может обращаться. Синтаксически записывается как ‘имя пользователя’@’имя хоста’.

Таким образом, причина возникновения MySQL error 1045 — неправильная комбинация трех параметров: имени пользователя, хоста и пароля.

В качестве имени хоста могут выступать ip адреса, доменные имена, ключевые слова (например, localhost для обозначения локальной машины) и групповые символы (например, % для обозначения любого компьютера кроме локального). Подробный синтаксис смотрите в документации

Замечание: Важно понимать, что в базе не существует просто пользователя с заданным именем (например, root), а существует или пользователь с именем root, имеющий право подключаться с заданного хоста (например, root@localhost) или даже несколько разных пользователей с именем root (root@127.0.0.1, root@webew.ru, root@’мой домашний ip’ и т.д.) каждый со своим паролем и правами.

Примеры.
1) Если вы не указали в явном виде имя хоста

GRANT ALL ON publications.* TO ‘ODBC’ IDENTIFIED BY ‘newpass’;

то у вас будет создан пользователь ‘ODBC’@’%’ и при попытке подключения с локальной машины вы получите ошибку:

ERROR 1045 (28000): Access denied for user ‘ODBC’@‘localhost’ (using password: YES)

так как пользователя ‘ODBC’@’localhost’ у вас не существует.

2) Другой первопричиной ошибки mysql 1045 может быть неправильное использование кавычек.

CREATE USER ‘new_user@localhost’ IDENTIFIED BY ‘mypass’; — будет создан пользователь ‘new_user@localhost’@’%’

Правильно имя пользователя и хоста нужно заключать в кавычки отдельно, т.е. ‘имя пользователя’@’имя хоста’

3) Неочевидный вариант. IP адрес 127.0.0.1 в имени хоста соответствует ключевому слову localhost. С одной стороны, root@localhost и ‘root’@’127.0.0.1’ это синонимы, с другой, можно создать двух пользователей с разными паролями. И при подключении будет выбран тот, который распологается в таблице привелегий (mysql.user) раньше.

4) Аккаунт с пустым именем пользователя трактуется сервером MySQL как анонимный, т.е. позволяет подключаться пользователю с произвольным именем или без указания имени.
Например, вы создали пользователя »@localhost с пустым паролем, чтобы каждый мог подключиться к базе. Однако, если при подключении вы укажите пароль отличный от пустого, то получите ошибку 1045. Как говорилось ранее, нужно совпадение трех параметров: имени пользователя, хоста и пароля, а пароль в данном случае не совпадает с тем, что в базе.

Что делать?

Во-первых, нужно убедиться, что вы используете правильные имя пользователя и пароль. Для этого нужно подключиться к MySQL с правами администратора (если ошибка 1045 не дает такой возможности, то нужно перезапустить сервер MySQL в режиме —skip-grant-tables), посмотреть содержимое таблицы user служебной базы mysql, в которой хранится информация о пользователях, и при необходимости отредактировать её.

Пример.

SELECT user,host,password FROM mysql.user;
+—————+——————+——————————————-+
| user          | host            | password                                  |
+—————+——————+——————————————-+
| root          | house-f26710394 | *81F5E21E35407D884A6CD4A731AEBFB6AF209E1B |
| aa            | localhost       | *196BDEDE2AE4F84CA44C47D54D78478C7E2BD7B7 |
| test          | localhost       |                                           |
| new_user      | %               |                                           |
|               | %               | *D7D6F58029EDE62070BA204436DE23AC54D8BD8A |
| new@localhost | %               | *ADD102DFD6933E93BCAD95E311360EC45494AA6E |
| root          | localhost       | *81F5E21E35407D884A6CD4A731AEBFB6AF209E1B |
+—————+——————+——————————————-+

Если изначально была ошибка:

  • ERROR 1045 (28000): Access denied for user ‘root’@‘localhost’ (using password: YES)

    значит вы указывали при подключении неверный пароль, так как пользователь root@localhost существует. Сам пароль храниться в зашифрованном виде и его нельзя узнать, можно лишь задать новый

    SET PASSWORD FOR root@localhost=PASSWORD(‘новый пароль’);

  • ERROR 1045 (28000): Access denied for user ‘ODBC’@‘localhost’ (using password: YES)

    в данном случае в таблице привилегий отсутствует пользователь ‘ODBC’@’localhost’. Его нужно создать, используя команды GRANT, CREATE USER и SET PASSWORD.

Экзотический пример. Устанавливаете новый пароль для root@localhost в режиме —skip-grant-tables, однако после перезагрузки сервера по прежнему возникает ошибка при подключении через консольный клиент:
ERROR 1045 (28000): Access denied for user ‘root’@‘localhost’ (using password: YES)
Оказалось, что было установлено два сервера MySQL, настроенных на один порт.

phpmyadmin

При открытии в браузере phpmyadmin получаете сообщение:

Error
MySQL said:

#1045 — Access denied for user ‘root’@’localhost’ (using password: NO)
Connection for controluser as defined in your configuration failed.
phpMyAdmin tried to connect to the MySQL server, and the server rejected the connection. You should check the host, username and password in your configuration and make sure that they correspond to the information given by the administrator of the MySQL server.

Ни логина, ни пароля вы не вводили, да и пхпадмин их нигде требовал, сразу выдавая сообщение об ошибке. Причина в том, что данные для авторизации берутся из конфигурационного файла config.inc.php Необходимо заменить в нем строчки

$cfg[‘Servers’][$i][‘password’] = »;      // MySQL password (only needed

на

$cfg[‘Servers’][$i][‘user’] = ‘ЛОГИН’;      
$cfg[‘Servers’][$i][‘password’] = ‘ПАРОЛЬ’

Установка новой версии

Устанавливаете новую версию MySQL, но в конце при завершении конфигурации выпадает ошибка:

ERROR Nr. 1045
Access denied for user ‘root’@‘localhost’ (using password: NO)

Это происходит потому, что ранее у вас стоял MySQL, который вы удалили без сноса самих баз. Если вы не помните старый пароль и вам нужны эти данные, то выполните установку новой версии без смены пароля, а потом смените пароль вручную через режим —skip-grant-tables.

Are you looking for a solution to fix the MySQL ERROR 1045 (28000): Access denied for user ‘user’@’localhost’ (using password: YES) error message?

If you’re an experienced MySQL database manager, you may have come across some vague and confusing problems, like MySQL Error 1045 (28000) messages. Fortunately, while resolving this error can be confusing at first due to its many potential causes, its solutions tend to be relatively simple. Once you determine the reason behind the database error you’re seeing, you should be able to fix it fairly quickly.

In this post, we’ll cover the various possible causes of the MySQL Error 1045 (28000). Then we’ll share solutions for each common situation, to help you get your database and your site back up and running.

Why the MySQL Error 1045 (28000) Error Occurs

The MySQL Error 1045 (28000) is an authentication error. «MySQL ERROR 1045 (28000): Access denied for user ‘user’@’localhost’ (using password: YES)» typically indicates that MySQL cannot log you in using the username and password you’ve specified.

This usually occurs when you provide an incorrect username/password combination when making the database connection. However, there are many other different situations that can lead to this type of behaviour.

  • Connecting to the wrong host or port
  • Provided user does not exist
  • User does exist but client host have insufficient permission to connect, or be IP banned
  • Wrong password provided
  • Bash converts special characters in the password to a different encoding

Wrong host or port

If you don’t specify the host to connect (with the -h flag), MySQL client will try to automatically connect to the localhost instance. You may be trying to connect to another host/port instance. In this case, simply add -h flag followed by the hostname you’re trying to connect to.

Code language: HTML, XML (xml)

Also, double check if you are trying to connect to the right port. MySQL, by default, listen on port 3306, but different setups use different ports for security purposes. Providing -P flag and a port number in the command is a great way to remind you of this detail.

[[email protected]]# mysql -u root -psekret -h <IP_or_hostname> -P 3306

Code language: HTML, XML (xml)

Provided user does not exist

MySQL stores user data in a table called user in a database named mysql (by default). The following query will return 1 if a user with the specified username exists, 0 otherwise.

mysql> SELECT EXISTS(SELECT 1 FROM mysql.user WHERE user = 'username') Query OK, 0 rows affected (0.00 sec)

Code language: JavaScript (javascript)

If the user does not exist, you can create a new user:

mysql> CREATE USER 'username'@'localhost' IDENTIFIED BY 'password'; Query OK, 0 rows affected (0.00 sec)

Code language: JavaScript (javascript)

Client host have insufficient permission

By default, the MySQL server listens for connections only from localhost, which means it can be accessed only by applications running on the same host.

Remote root access is disabled by default. If you want to enable that, run this SQL command locally:

GRANT ALL PRIVILEGES ON *.* TO 'root'@'%' IDENTIFIED BY 'password' WITH GRANT OPTION; FLUSH PRIVILEGES;

Code language: JavaScript (javascript)

And then find the following line and comment it out in your my.cnf file, which usually lives on /etc/mysql/my.cnf on Unix/OSX systems. In some cases the location for the file is /etc/mysql/mysql.conf.d/mysqld.cnf).

Alternatively, you can check to see which host user/host MySQL allows connections with the following query:

mysql> SELECT Host, User FROM mysql.user WHERE User='user01'; +-------------+-------------+ | Host | User | +-------------+-------------+ | 192.168.0.1 | user01 | +-------------+-------------+ 1 row in set (0.00 sec)

Code language: JavaScript (javascript)

Wrong password provided

This is by far the most common reason for MySQL ERROR 1045 (28000): Access denied for user ‘user’@’localhost’ (using password: YES).

MySQL lists user accounts in the user table of the mysql database. Each MySQL account can be assigned a password, although the user table does not store the cleartext version of the password, but a hash value computed from it.

You cannot read user passwords in plain text from MySQL as the password hash is used for authentication, but if you can get into MySQL command line interface (with root privileges), you can compare what you remember with the hashed value with “PASSWORD” function with the command below.

mysql> SELECT Host, User, authentication_string, PASSWORD('forgotten') FROM mysql.user WHERE User='nonexistant'; +-------------+-------------+-------------------------------------------+-------------------------------------------+ | Host | User | authentication_string | PASSWORD('forgotten') | +-------------+-------------+-------------------------------------------+-------------------------------------------+ | 192.168.0.1 | nonexistant | *AF9E01EA8519CE58E3739F4034EFD3D6B4CA6324 | *70F9DD10B4688C7F12E8ED6C26C6ABBD9D9C7A41 | | % | nonexistant | *AF9E01EA8519CE58E3739F4034EFD3D6B4CA6324 | *70F9DD10B4688C7F12E8ED6C26C6ABBD9D9C7A41 | +-------------+-------------+-------------------------------------------+-------------------------------------------+ 2 rows in set, 1 warning (0.00 sec)

Code language: JavaScript (javascript)

From the output, we can clearly see that the hashed value for ‘forgotten’ does not match the authentication_string column, which means ‘forgotten’ is the wrong password.

Executing the following query will overwrite the current password with a new one :

mysql> set password for 'nonexistant'@'%' = 'helloworld'; Empty set (0.00 sec)

Code language: PHP (php)

Special characters in the password

If you’re using Bash as your main shell, you should know that not all characters are treated equal in Bash. Some characters are evaluated by Bash to have a non-literal meaning. Instead, these characters carry out a special instruction, or have an alternate meaning; they are called «special characters», or «meta-characters».

In this case, your password contains some of the those special characters which might be mistakenly converted to another form by Bash. To prevent this from happening, wrap your password in single quotes in the command:

[[email protected]]# mysql -u user01 -p'hello$!*&^%$#@!' mysql: [Warning] Using a password on the command line interface can be insecure ... mysql>

Code language: PHP (php)

Regain access to the database

If you’re locked out and need to bypass the authentication mechanisms to regain access to the database, here are simple steps to do so. Please note that we’re using MariaDB to demonstrate the steps.

  1. Stop the instance by running sudo systemctl stop mariadb
  2. Use mysqld_safe to start mysqld server by running the command: mysqld_ safe –user=mysql –skip-grant-tables –skip-networking
  3. Now you can open up a new terminal and access the MySQL server instance with root privileges by running mysql -u root -h localhost .
  4. Please do note that since we’re running grant-skip-tables, any GRANT/CREATE/SET PASSWORD statements won’t work straight away. In order to fix this, run FLUSH PRIVILEGES;.
  5. Run SET PASSWORD FOR 'root'@'localhost' = '[email protected]!' to change the password for root user.
  6. Alternatively, you can modify mysql.users table with a query which modifies the password for User and Host like UPDATE mysql.user SET authentication_string=PASSWORD(‘newpwd’) WHERE User=’root’ and Host=’localhost’;
  7. Stop the mysqld_safe instance and restart MySQL again from systemctl.
  8. You should be able to login with root from the localhost with the new password and do any other necessary corrective operations with root user.

I just installed a fresh copy of Ubuntu 10.04.2 LTS on a new machine. I logged into MySQL as root:

david@server1:~$ mysql -u root -p123

I created a new user called repl. I left host blank, so the new user can may have access from any location.

mysql> CREATE USER 'repl' IDENTIFIED BY '123';
Query OK, 0 rows affected (0.00 sec)

I checked the user table to verify the new user repl was properly created.

mysql> select host, user, password from mysql.user;
+-----------+------------------+-------------------------------------------+
| host      | user             | password                                  |

| server1   |                  |                                           |
| localhost | debian-sys-maint | *27F00A6BAAE5070BCEF92DF91805028725C30188 |
| %         | repl             | *23AE809DDACAF96AF0FD78ED04B6A265E05AA257 |
+-----------+------------------+-------------------------------------------+
8 rows in set (0.00 sec)

I then exit, try to login as user repl, but access is denied.

david@server1:~$ mysql -u repl -p123
ERROR 1045 (28000): Access denied for user 'repl'@'localhost' (using password: YES)
david@server1:~$ mysql -urepl -p123
ERROR 1045 (28000): Access denied for user 'repl'@'localhost' (using password: YES)
david@server1:~$ 

Why is access denied?

The reason you could not login as repl@'%' has to do with MySQL’s user authentication protocol. It does not cover patterns of users as one would believe.

Look at how you tried to logged in

mysql -u repl -p123

Since you did not specify an IP address, mysql assumes host is localhost and tries to connect via the socket file. This is why the error message says Access denied for user 'repl'@'localhost' (using password: YES).

One would think repl@'%' would allow repl@localhost. According to how MySQL perform user authentication, that will simply never happen. Would doing this help ?

mysql -u repl -p123 -h127.0.0.1

Believe it or not, mysql would attempt repl@localhost again. Why? The mysql client sees 127.0.0.1 and tries the socket file again.

Try it like this:

mysql -u repl -p123 -h127.0.0.1 --protocol=tcp

This would force the mysql client to user the TCP/IP protocol explicitly. It would then have no choice but to user repl@'%'.

You should issue for localhost specific to it.

  GRANT USAGE ON *.* TO 'repl'@'localhost' IDENTIFIED BY '123';

And try connecting.

The problem is these two accounts, added by default.

http://dev.mysql.com/doc/refman/5.5/en/default-privileges.html

+-----------+------------------+-------------------------------------------+
| host      | user             | password                                  |
+-----------+------------------+-------------------------------------------+
| localhost |                  |                                           |
| server1   |                  |                                           |
+-----------+------------------+-------------------------------------------+

A blank user name is a wildcard, so no matter what account you use, it matches this user if MySQL thinks you’re connecting from localhost or your local server name (server1 in this case)… since they have no password, any password you try is wrong. User authentication only tries the first match, so the user you created never gets noticed when your host is localhost (or your server name).

Delete these two from the mysql.user table and then FLUSH PRIVILEGES;.

Or, the mysql_secure_installation script can do this for you, although I tend to prefer doing things manually.

Make sure that all fields in the connector are set up with the correct details

host = «localhost»,
user = «CorrectUser»,
passwd = «coRrectPasswd»,
database = «CorreCTDB»

Check for upper and lowercase errors as well — 1045 is not a Syntax error, but has to do with incorrect details in the connector

This could be an issue with corruption of your mysql database. Tables inside mysql database like user table can get corrupt and may cause issued.

Please do a check on those

myisamchk /var/lib/mysql/mysql/ *.MYI

Usually while checking or fixing myisam tables we would like to take mysql down first. If this problem is still not solve please try this out aswell.

If they are corrupt then you can fix them using

myisamchk —silent —force —fast /path/table-name.MYI

Thanks,

MySQL users often face an issue called Error 1045 (28000) access denied for user ‘root’@’localhost’ (using password: yes). This usually occurs when you enter an incorrect password or password for your database. Fixing these credentials can resolve this error in no time.

In this article, we will look at the ways to resolve this error.

How to fix “Error 1045 (28000) access denied for user ‘root’@’localhost’ (using password: yes)”?

The error looks something like this — 

mysql -uroot -proot

ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

It arises when you perform a fresh installation of MySQL and try to login with a password. The default password of MySQL is blank () (i.e. empty string).

So, you can login to the MySQL server using the same password.

Example  

>mysql -uroot -p

Enter password:

Welcome to the MariaDB monitor.  Commands end with ; or g.

Your MariaDB connection id is 9

Server version: 10.4.11-MariaDB mariadb.org binary distribution

Copyright (c) 2000, 2018, Oracle, MariaDB Corporation Ab and others.

Type ‘help;’ or ‘h’ for help. Type ‘c’ to clear the current input statement.

MariaDB [(none)]>

mysql login

The best practice is to change the password after the new installation.

Set root user password

You must set the root user password after performing the new installation. Here is the code to set it –

Login as user root with blank password

>mysql -u root

mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'abc';

Now the new password for root user is abc.

How to fix the Error 1045 (28000)?

Let us look at the ways to fix this problem – 

  1. Enter the correct credentials

The primary method to fix this error is to enter the correct username and password using the following command –

mysql –u username –p       
  1. Ensure the user is correct

Sometimes, the user you might be trying to access does not exist on the MySQL server. You can check if the user exists using the following code-

MariaDB [(none)]> select user from mysql.user where user like '%root%';

+------+

| User |

+------+

| root |

| root |

| root |

+------+

3 rows in set (0.001 sec)  

select user root

If the user does not exist, create it with the desired username.

  1. Enter the correct host name

You might be trying to access the server from a host that is different from the defined host name. You will encounter Error 1045 in this case. You can use this code to view details of the user –

To fix this, you can update the host name for the user using the code below –

mysql> mysql -u root -pabc -h <IP> -P 3306

You might encounter the error in due to the following scenarios –   

Entered wrong password

>mysql -uroot -pssssss

ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)

Host doesn’t not have permission to connect database

This is a very common error that occurs while connecting to a remote database. While connecting to such a database we need to give access to the HOST IP ADDRESS to connect to it.

This is the IP Address of the source system which connects to the database server.

If access is not given, then run the given command –

CREATE USER ‘dbuser1’@'< Host IP >’ IDENTIFIED VIA mysql_native_password USING ‘***’;GRANT ALL PRIVILEGES ON *.* TO ‘dbuser1’@'< Host IP >’ REQUIRE NONE WITH GRANT OPTION MAX_QUERIES_PER_HOUR 0 MAX_CONNECTIONS_PER_HOUR 0 MAX_UPDATES_PER_HOUR 0 MAX_USER_CONNECTIONS 0;

Conclusion

Apart from all this, make sure the host contains the correct IP address and host name, to avoid the Error 1045 (28000) access denied for user ‘root’@’localhost’ (using password: yes).

При создании пользователя базы данных MySQL учитывается 3 параметра, а не два. Первый параметр это username, имя пользователя базы данных, второй параметр, это имя хоста, под именем хоста подразумевается разрешение входа в базу, или с определенного IP адреса, или с определенного домена, или с любой машины кроме локальной, или только с локальной машины. Под локальной машиной подразумевается Ваш сервер, где расположена сама база данных и панель phpmyadmin.

Поясняю:

  • Пользователь например, root@localhost имеет имя root, свой пароль и право входить только с локальной машины, то есть с Вашего сервера через командную строку или панель управления.
  • Пользователь например, root@’мой домашний ip’ имеет имя root, свой пароль и право входить только с домашнего компьютера.
  • Пользователь например, root@’%’ имеет имя root, свой пароль и право входить с любого компьютера, кроме локального, то есть Вашей панели управления веб сервером.

Знак ‘%’ в одинарных кавычках указывает именно на право входить в базу с любого компьютера, кроме локальной машины.

Пользователей с именем root может быть два, три и более. Все эти пользователи будут иметь разные пароли и разные разрешения на вход с определенных хостов.

Ошибка 1045

ERROR 1045 (28000): Access denied for user ‘ root’@’localhost’ (using password: YES)

Самая распространенная и банальная ошибка это неправильная пара логина и пароля для входа в БД. Грубо говоря, Вы можете пытаться входить под пользователем root@’%’, вводя правильный никнейм и пароль через установленную на сервере панель  phpmyadmin. Но данный пользователь имеет право заходить с любого компьютера, кроме локальной машины. А панель phpmyadmin как раз является локальной машиной. Таким образом Вы будите получать данную ошибку.

Решение:

Самое простое, это попробовать ввести другой пароль от указанного пользователя. Но пароль может быть задан автоматически (в частности root), может быть пустым или просто утерянным.

Вам необходимо войти в MySQL через терминал в командной строке. Лично я использую программу putty, как и 99% администраторов веб сервера. Для того, чтобы попасть в БД, необходимо предварительно отредактировать конфигурационный файл под названием my.cnf. В операционной системе Centos 7 он находится /etc/my.cnf. Скачайте данный файл с сервера и вставьте в него после  такую строку: skip-grant-tables, должно получится примерно так:


[mysqld]
skip-grant-tables
другие параметры

Залейте файл с новыми параметрами на сервер, предварительно удалив старый, а лучше просто переименуйте старый файл. Перезапустите сервер БД через Вашу панель управления.

После редактирования выше указанного файла попасть в MySQL можно без пароля со всеми привилегиями.

Теперь откройте терминал и войдите под пользователем root без пароля, введя команду:


sudo mysql -u root

Далее введите команду:


SELECT user,host,password FROM mysql.user;
Если все сделали правильно, то будет показано вот такое окно:

Вход в базу данных без пароля

Вход в БД под root без пароля

Из таблицы видно, что пользователя root вообще НЕ существует, однако после правки выше указанного конфига, я без труда вошел под root и без пароля. Так же видно из таблицы, что присутствуют 2 пользователя — admin с паролями и доступом с локальной машины (непосредственно с сервера через панель phpmyadmin) и с любого домашнего компьютера через терминал.

Этих пользователей я создавал сам и пароли от них я знаю. Исходя из полученной информации, я могу без труда войти в панель phpmyadmin. И создать любого необходимого пользователя с любыми привилегиями (правами).

Пользователь root отсутствует по причине удаления. Я его просто удалил для написания данной статьи. У вас он скорей всего присутствует и таблица будет гораздо шире. Это просто мой тестовый сервер для экспериментов.

Давайте посмотрим еще один пример с другого сервера.

Вход в MariaDB без пароля

Список пользователей БД

По root у Вас будет примерно такая же картина. То есть один root имеет право войти в панель phpmyadmin с паролем. Один root имеет право на вход через терминал без пароля и т. д. Пароли в БД хранятся в зашифрованном виде.

Получив данную информацию, Вы сможете разобраться с доступами, найти необходимый пароль и войти в панель phpmyadmin.

НО увы, так бывает НЕ всегда!

2 способ устранения ошибки mysql 1045

Как уже писалось в начале статьи данная ошибка возникает после обновления ПО на сервере. И зачастую в панель phpmyadmin просто НЕ попасть. Если из первого раздела Вам не удалось разобраться с пользователями и паролями, то проще всего создать нового пользователя с правами администратора и войти в панель.

Выполнить это можно через терминал. Войдите на сервер через терминал с правами администратора и проверьте есть ли доступ без пароля. Как правило на сервере создается один пользователь root со входом без пароля из терминала.  Введите команду:


sudo mysql -u root

Если на сервер баз данных попасть не удалось, то отредактируйте файл (my.cnf), как рассказано в первом способе и повторите команду:


sudo mysql -u root

Теперь, когда в БД удалось попасть через терминал, необходимо создать нового пользователя с паролем и правами админа. Команда:


CREATE USER 'root'@'localhost' IDENTIFIED BY 'ЗДЕСЬ ПАРОЛЬ';

Следующей командой предоставляются права администратора:


GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost' WITH GRANT OPTION;

После создания нового пользователя, как правило, можно под ним зайти в панель phpmyadmin. Это может быть совсем не обязательно пользователь root, а любой другой. Запомните имя пользователя и пароль, где то запишите себе. Лучше НЕ использовать root при создании нового пользователя.

Внимание!!! Не забудьте обратно отредактировать файл my.cnf, то есть удалить строку — skip-grant-tables.

3 способ устранения ошибки mysql 1045

Пожалуй, самый сложный способ, попытаюсь объяснить простым языком. Дело в том, что root пользователь создается по умолчанию. И если Вы начинаете играться с этим пользователем (root), то Вы нарушите пару логин — пароль. Так как пароль для этого пользователя создается и хранится в нескольких файлах на сервере.

Давайте поставим точку, рассмотрим все эти файлы и при необходимости зададим один пароль к данному юзеру.

Итак,

Файлов к счастью у нас не много, точнее три места которые необходимо проверить и поправить при необходимости.

  • Первое, открываем файл config.inc.php в Centos 7 находится /etc/phpmyadmin/config.inc.php В самый конец этого файла добавьте следующие строки кода:


/* User for advanced features */
$cfg['Servers'][$i]['controluser'] = ' root';
$cfg['Servers'][$i]['controlpass'] = 'ЗДЕСЬ ПАРОЛЬ';

  • Второе, в файле /usr/local/vesta/conf/mysql.conf. Я использую панель управления VestaCP, если у Вас другая панель, то расположение файла будет отличатся. Откройте данный файл и посмотрите какой там указан пароль, если нужно, то смените на Ваш.
  • Третье, это непосредственно сама панель управления phpmyadmin.

Во всех трех местах, должны быть одинаковые пароли от этого юзера. Если не так, то исправляйте. В VestaCP при неправильных паролях в этих файлах может отвалится бэкап.

Заключение по устранению ошибки mysql 1045

Ошибка mysqli real connect 1045, как правило появляется при неправильной паре имя — пароль или после обновления ПО на сервере. Устраняется путем проверки пользователей через терминал и создания новых пользователей. В случаи не корректного пароля от root редактируются необходимые файлы.

P. S.

Я отлавливал все 3 причины сбоя панели управления phpmyadmin и данную статью публикую больше для себя как памятку по устранению неполадок. Но надеюсь Вам она тоже поможет. Оставляйте комментарии по решению данной проблемы.

Думаю, что теперь Вам не страшна ошибка mysqli_connect(): (HY000/1045): Access denied for user ‘username’@’localhost’.
