Laravel 500 server error ubuntu

I have installed Laravel many times on Windows OS but never had this problem.

However, on Ubuntu 14.04 I am getting a 500 Internal Server Error, and messages like this in my logs:

[Wed Jul 22 10:20:19.569063 2015] [:error] [pid 1376] [client 127.0.0.1:52636] PHP Fatal error: require(): Failed opening required ‘/var/www/html/laravel_blog/../bootstrap/autoload.php’ (include_path=’.:/usr/share/php:/usr/share/pear’) in /var/www/html/laravel_blog/index.php on line 22

Previously I’ve had problems when mod_rewrite was not installed or set up properly, but I have installed it and it is not working. Changed .htaccess as well from original to this.

    +FollowSymLinks
RewriteEngine On

RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.php [L]

I’ve given access to all my folders and files inside i.e.

/var/www/html/laravel_project

I have all the necessary extensions needed for Laravel 5+ as well. Is there something left that I didn’t do?

Make sure a .env file, containing an APP_KEY, exists in root.

What should be in the .env hasn’t been explicitly stated in other solutions, and thought I’d boil it down to the sentence above.

This fixed my 500 error on a fresh install of Laravel.

Steps:

1. Create a .env file in root (e.g. touch .env)
2. Make sure it contains at least one line: APP_KEY=
3. Generate an app key in terminal: php artisan key:generate

More .env paramaters:

As a reference, here’s the official .env with useful baseline parameters. Copy-paste what you need:

https://github.com/laravel/laravel/blob/master/.env.example

Notes:

• My particular installation didn’t include any .env whatsoever (example or otherwise)

• Simply having a blank .env does not work.

• A .env containing parameters, but no APP_KEY parameter, does not work.

Bug?: When generating an app key in terminal, it seems to falsely report success, however no key will actually get placed in the .env if the file is missing a line starting with APP_KEY=.

Create .env file with the below cmd command:

cp .env-example .env

Then generate a key for your project:

php artisan key:generate

After that clear your caches using the below commands:

//---Delete Configuration Cahce
php artisan config:cache
//---Clear Application Cache
php artisan cache:clear

run these commands

1. composer install 
2. mv .env.example .env 
3. php artisan cache:clear 
4. composer dump-autoload 
5. php artisan key:generate

I had this problem …

I read all the comments and suggestions. 500 — HTTP ERROR CODE represents internal server error.

Reasons for this error:

• These mainly cause due to permission issues
• Environment variables not found or .env file not found on your root directory
• PHP extensions problem
• Database problem

Fix:

• Set the correct permissions:

• Run these commands (Ubuntu/Debian)

find /path/to/your/root/dir/ -type f -exec chmod 644 {} ;
find /path/to/your/root/dir/ -type d -exec chmod 755 {} ;

chown -R www-data:www-data /path/to/your/root/dir/

chgrp -R www-data storage bootstrap/cache
chmod -R ug+rwx storage bootstrap/cache

• If .env file doesn’t exist, create one by touch .env and paste your environment variables and then run

   php artisan key:generate
   php artisan cache:clear
   php artisan config:clear
   composer dump-autoload

• Check your php.ini file and uncomment the extensions you need (In some case you have to install the extension by running this command apt-get install php7.2-[extension-name]
• Check your database credentials and values in .env file. And grant permissions to the database user for that database.

These are some common problem you likely going to face when deploying your laravel app and once you start getting all these commands, I suggest you to make a script which will save your time.

A frequent issue when using git:

Laravel's .gitignore ignores the .env file which when missing generates this error

Solved this by manually adding an .env file on the server or uploading it through FTP

First, if there is not .env file in your Laravel repository. Copy the .env.example file using the following cmd command cp .env.example .env and open .env file and apply your configuration if needed.

Run these commands:

//---Generate Key in your project
php artisan key:generate
//---Flush the application cache
php artisan cache:clear
//---Remove the configuration cache file
php artisan config:cache
php artisan config:clear
//---Regenerates the list of all classes that need to be included in the project
composer dump-autoload
//---Restart your Server
php artisan serve

Run these two commands in the directory where Laravel is installed:

sudo chmod 755 -R DIRECTORY_NAME
chmod -R o+w DIRECTORY_NAME/storage

Then clear the cache and dump the auto load:

php artisan cache:clear
composer dump-autoload

I have faced this problem many times. Try one of these steps it helped me a lot. Maybe it will also help you.

1. First of all check your file permissions.
2. To fix file permissions sudo chmod 755 -R your_project
3. Then chmod -R o+w your_project/storage to write file to storage folder.
4. php artisan cache:clear
   composer dump-autoload
5. php artisan key:generate
6. Then check server requirements as per the laravel requirement.
7. Many times you got this error because of the php version. Try changing your php version in cpanel.
8. Then configure your .htaccess file properly

If you use vagrant, try this:

First remove config.php in current/vendor.

Run these command:

php artisan config:clear
php artisan clear-compiled
php artisan optimize

NOT RUN php artisan config:cache.

Hope this help.

if its on a live server try this

<IfModule mod_rewrite.c>
<IfModule mod_negotiation.c>
    Options -MultiViews -Indexes
</IfModule>
Options +FollowSymLinks
RewriteEngine On
RewriteBase /


# Handle Authorization Header
RewriteCond %{HTTP:Authorization} .
RewriteRule .* - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]

# Redirect Trailing Slashes If Not A Folder...
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_URI} (.+)/$
RewriteRule ^ %1 [L,R=301]

# Handle Front Controller...
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^ index.php [L]

then also make sure that the php version in your composer.json is the same as that of your server.

Check your php version in your terminal using php -v

Run these two commands on root of laravel

find * -type d -print0 | xargs -0 chmod 0755 # for directories

find . -type f -print0 | xargs -0 chmod 0644 # for files

I have a similar issue with a share Host. I was having 500 error. I just fixed by checking the Laravel version and PHP version. The error was because Laravel 5.6 doesn’t run on PHP 7.0.x Once I know this I just reconfigure the project to Laravel 5.5 that is compatible with PHP 7.0.x now everything is right. Another reason I have issues sometimes is the FTP I get corrupted Files and have to upload the project more than once.
Hope this help in the future I don’t found so many information in this topic.

For those of you who like me still got errors after trying all the other answers :

Check the version of php apache uses, latest laravel only works with php7.1.
So you have to :

sudo a2dismod php[yourversion]
sudo a2enmod php7.1
sudo systemctl restart apache2

hope this helps

According to the logs :

There are some failures opening files into the /vendor folder.

By installing and updating via composer, I was able to finally solve the issue.

sudo composer install
sudo composer update

Make sure storage folder with write previlege (chmod o+w), work for me like a charm.

Because of no right to write the log’s directory.
chmod 755 storage -R
