Почему не работает созданная служба systemd?

Здравствуйте.
Появиласть необходимость запускать программу при загрузке системы и перезапускать в случае её закрытия или краха. Debian 8.1 располагает для этого инстументом systemd.
Был создан юнит с именем dts.service

Который запускает следующий скрипт /home/dts/bin/dts-service.sh

При выполнении этот скрипт запускает программу khconsole которая должна все время работать если она закрылась или повисла то systemd должен перезапустить её.

Проблема в следующем:
Отдельно, скрипт отрабатывает корректно. При попытке запуска через systemd получаю следующий результат
Job for dts.service failed. See ‘systemctl status dts.service’ and ‘journalctl -xn’ for details.

Не понятно почему служба не стартует, хотя скрипт корректный и не должен завершаться?

[SOLVED]Starup sript not getting executed in systemd

I have a script(rpi_user.sh) which has to be executed every time when I start my computer. But the startup script is not executing. Following are the steps which I have done. I am using systemd. I upgraded my system successfully today.

The script which I wanted to execute was very small and easy. I just creates a new file with the echoed text. Below is my script(rpi_user.sh)
cd /home/pi/
echo Jeffrey > 1

When ever I restart my system, I am not able to see the file ‘1’

I made the startup script(rpi_user.sh) and kept in /usr/bin. Also I followed the instruction in https://wiki.archlinux.org/index.php/Sy … process.3F

Below shown in my service file (rpi_user.service)
[Unit]
Description=rpi_user

After creating rpi_user.sh, I executed the following command to make the file executable — chmod +x rpi_user.sh

Once completing these steps, I executed the following commands (I got these info from http://forum.teamspeak.com/showthread.p … up-script)
# systemctl —system daemon-reload
# systemctl start rpi_user.service
# systemctl enable rpi_user.service
# systemctl status rpi_user.service

But things didn’t go fine. When I ran «systemctl status rpi_user.service», I got the following error

rpi_user.service — rpi_user
Loaded: loaded (/etc/systemd/system/rpi_user.service; enabled)
Active: failed (Result: exit-code) since Sun, 23 Sep 2012 03:29:08 +0530; 1min 33s ago
Main PID: 247 (code=exited, status=203/EXEC)
CGroup: name=systemd:/system/rpi_user.service

Sep 23 03:29:08 alarmpi systemd[247]: Failed at step EXEC spawning /usr/bin/rpi_user.sh: Exec format error

Could anyone of you answer the following questions.
1) Is there any thing wrong which I have done ? Is this the way to create startup scripts ?
2) Could you help me in fixing the issue — how can I make my starup script run ?

Thanks and Best Regards,
Jeffrey Antony

/bin/bash: Exec format error

I have a weird issue on an Ubuntu 10.04 LTS virtual server. A few days ago I started getting these alerts:

Now logging in to the server does not work. It seems like I am able to authenticate with ssh but then seems to fail at getting a prompt. I get:

I can’t login from any account. Can’t try single user as it is remotely hosted. I can connect without starting a shell using ssh -N.

I’ve received this from cron. It seems like all my /bin files are gone. Is there any way to recover?

Any help would be greatly appreciated.

Can you login to a different account (if one exists)? Can you login to the console? Or reboot in single user mode and login? Can you connect with something like WinSCP, which shouldn’t start a shell?

That error may mean you have a bad login script.

It could also mean that bash has been replaced with a corrupt or different architecture’s bash, which might be a sign that someone tried to install a rootkit.

That paste looks like severe filesystem corruption.

At this point, were it my server, I would:

  • Check the disks for hardware failure and replace any disk that has failed, is failing, or even looks like it might fail in the near future.
  • Reinstall the OS and restore my data from the most recent good backup, checking them carefully to ensure that I’m not restoring corrupt data. This could have been going on for quite a long time without your knowledge, so check your backup carefully before restoring it.

  • [SOLVED] systemd-resolved.service is not loaded properly: Exec format error.

  1. systemd-resolved.service is not loaded properly: Exec format error.

    Hi!

    I have a headless Ubuntu Server with some DNS trouble. After some troubeshooting to find out why it did not have an internet connection I found that starting systemd-resolved.service fixed the issue.
    I didn’t have time to figure out how to start it automatically at boot so I’ve been doing that manually via ssh for now.
    This time it won’t start the service;

    Code:

    $ sudo systemctl start systemd-resolved.service
Failed to start systemd-resolved.service: Unit systemd-resolved.service is not loaded properly: Exec format error.
See system logs and 'systemctl status systemd-resolved.service' for details.
$ systemctl status systemd-resolved.service
● systemd-resolved.service - dns
   Loaded: error (Reason: Exec format error)
   Active: inactive (dead)

    Some advice on how to troubleshoot would be great!

    System info:

    Code:

    $ uname -v
#74-Ubuntu SMP Tue Sep 17 17:06:04 UTC 2019
$ cat /etc/lsb-release 
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=18.04
DISTRIB_CODENAME=bionic
DISTRIB_DESCRIPTION="Ubuntu 18.04.3 LTS"

  2. Re: systemd-resolved.service is not loaded properly: Exec format error.

    What do you see in /var/log/syslog? That’s where systemd logs everything.

    An «Exec format error» usually means the executable program is somehow bad. Might I suggest reinstalling systemd-resolved?

    Code:

    sudo apt remove --purge systemd-resolved
sudo apt install systemd-resolved

    To tell systemd to run this program at boot, run the command

    Code:

    sudo systemctl enable systemd-resolved

    See: https://linoxide.com/linux-how-to/en…stemd-upstart/

    I tried tailing it but nothing happens. I can see other events, like me logging in to ssh, but nothing about systemd-resolved. «cat /var/log/syslog | grep resolved» gives nothing.

    Code:

    sudo apt remove --purge systemd-resolved
sudo apt install systemd-resolved

    Ok, I tried this but it says that systemd-resolved is not installed;

    Code:

...

    Is it possible to use apt without internet? I am running Linux Mint on another machine. Can I download the files needed there and copy them over to my server?

  4. Lightbulb Re: systemd-resolved.service is not loaded properly: Exec format error.

    Ok, so I’ve been tinkering with this a bit and I found a solution.

    Being the linux-noob that I am, I might be doing this a bit cumbersome.
    I tried to figure out if I could somehow download the packages on another pc and copy them over, but I didn’t find what I needed. I found something called openvpn-systemd-resolved https://packages.ubuntu.com/bionic/o…stemd-resolved, but I’m not sure if it is the same as systemd-resolved. Also, from what I understand I would have to download all dependecies manually to transfer over to the server and install with dpkg, so I tried something else.

    I downloaded the ubuntu server 18.04 LTS image from canonical and installed it in a virtualbox vm.
    I could find from «sudo systemctl status systemd-resolved.service» which file was loaded;

    Code:

    ~$ sudo systemctl status systemd-resolved.service
● systemd-resolved.service - Network Name Resolution
   Loaded: loaded (/lib/systemd/system/systemd-resolved.service; enabled; vendor preset: enabled)
   Active: active (running) since Sat 2019-10-19 20:54:06 CEST; 14min ago

...

    I made a backup of this file on my server and copied over the one from the vm.

    Code:

    ~$ ls -la /lib/systemd/system/systemd-resolved*
-rw-r--r-- 1 root root 1687 Oct 19 20:48 /lib/systemd/system/systemd-resolved.service
-rw-r--r-- 1 root root  131 Oct 18 23:53 /lib/systemd/system/systemd-resolved.service_backup

    After a reboot it worked like charm.
    I notice that the file sizes are quite different, the old one is quite small compared to the new one.
    Any insight here would be great.

    Could I have done this an easier way? Should I have done it differently or is it ok to replace this service-file like I did?

  5. Thumbs up Re: systemd-resolved.service is not loaded properly: Exec format error.

    I figured out why the file was smaller. I didn’t know that those files were plain text-files, but now I had a look to see the difference and that led me to realise what the problem was.
    I use Webmin for administrating the server, and since the service didn’t start at boot, I tried enabling it in «Bootup and shutdown».
    It wasn’t in the list (still isn’t) so I tried «Create new systemd service». That replaced the service-file with a new one;

    Code:

    [Unit]
Description=dns

[Service]
ExecStart=sudo systemctl start systemd-resolved.service ; 

[Install]
WantedBy=multi-user.target

    Quote Originally Posted by SeijiSensei

    Code:

    sudo systemctl enable systemd-resolved

    I did that now, instead of using Webmin. Thank you very much

    Code:

    ~$ sudo systemctl enable systemd-resolved.service
Created symlink /etc/systemd/system/dbus-org.freedesktop.resolve1.service → /lib/systemd/system/systemd-resolved.service.

Hey guys!

After reading several threads and trying several things I still cannot get a custom service to start at boot. I need help.

Here is the story.

I want to delay some services at boot in order to decrease the boot time. So I made this (my first!) script

#!/bin/bash

#This script will run 3 sec after boot

 systemctl start dnsmasq.service &&
 systemctl start squid.service &&
 systemctl start squid-rotate.service

I tried putting the script in /usr/bin and in /usr/local/bin. It runs (manually) fine from either.

After that I created a service

[Unit]
Description=bootscript

[Service]
Type=oneshot
RemainAfterExit=yes
ExecStart=/usr/bin/bootscript

I tried adding

as well as changing the type to

After that I created a timer

[Unit]
Description=Runs bootscript at boot

[Timer]
# Time to wait after booting before activation
OnBootSec=3sec
Unit=bootscript.service

[Install]
WantedBy=multi-user.target

Then

systemctl enable bootscript.timer

And after a reboot I have no internet connection. I have to manually run the script in order to start the services.

Script is executable

chmod +x /usr/bin/bootscript

Here is the output

ctl status bootscript.service
● bootscript.service - bootscript

How to proceed to make it work?
