# chkconfig: 345 90 10

# Required-Stop: $sendmail $mysqld $httpd

mystart() {
   su -c '/myexecutable start' ejudge

mystop() {
   su -c '/myexecutable stop' ejudge

case "$1" in
        echo "Usage: $0 start|stop|restart"
        exit 1
exit 0

Open in new window

Commands performed:
chmod a+x myscript
chkconfig --add myscript
chkconfig --level 2345 myscript on

Open in new window

Testing workability:
ps ax | grep "myexecutable"
Does not give myexecutable as an output, so we conclude that application does not start.

The application must start on startup.

Thank you.

Hi, what version is your Fedora? Are you using an older version with SysVinit or a newer one with Systemd, seeing you're using chkconfig it should be a system using SysVinit ...
Nusrat NuriyevAuthor Commented:
Fedora 20.
Briefly, describe the differences between SysVinit and Systemd, and how to determine which one I belong
Zephyr ICTCloud ArchitectCommented:
There is no immediate default way to check if you have either SysVinit or Systemd or Upstart for that matter, there is a way you can check, like this for example:

 ps -eaf|grep [s]ystemd

Open in new window

But since it is Fedora 20 it is using Systemd by default normally ...

To know some differences between Systemd and SysVinit, check this list

If you want to run a script at startup you can create a Systemd file in /usr/lib/systemd/system/<your_service_name>.service.

It should look something like this:


ExecStart=/bin/bash <the_absolute_path_to_script>


Open in new window

Change the things between the brackets to comply with your setup.

Now tell Systemd to enable this service:

systemctl enable <your_service_name>.service

Open in new window

Reboot the system and see if the script runs like it should.
Check the messages log for info if it fails ( /var/log/messages).

Thank you for  systemd versus sysvinit information
Could we use command line arguments here?
ExecStart=/bin/bash <the_absolute_path_to_script>


ExecStart=/bin/bash <the_absolute_path_to_script> <argument1> <argument2>

Nusrat NuriyevAuthor Commented:
Another question is how to execute at shutdown which is binded to this service unit?

Actually, as you may see, I use single application which is started by
myexecutable start
terminate by
myexecutable stop

In sysvinit we have ability to do this, what about systemd?
Zephyr ICTCloud ArchitectCommented:
If I understand your first question here, then yes you can, check out the Fedora info here

I'm not sure I understand your second question completely, but in systemd you can start stop a service like this:

systemctl start
systemctl stop
Nusrat NuriyevAuthor Commented:
Then, systemd is not flexible enough, because I can't pass arguments to the executable, right?
Then, let's assume that we will solve the problem with good old sysinit?

Thank you.
Zephyr ICTCloud ArchitectCommented:
What are your arguments?

If you look at this example you can give certain arguments:

Description=Avahi mDNS/DNS-SD Stack

ExecStart=/usr/sbin/avahi-daemon -s
ExecReload=/usr/sbin/avahi-daemon -r


Open in new window

Nusrat NuriyevAuthor Commented:
What is ExecReload?
Zephyr ICTCloud ArchitectCommented:
It's used when your application/service supports reloading ... So as the name of it suggest.

You can leave this option blank if your service doesn't support it.
Nusrat NuriyevAuthor Commented:
ok, what happened with the service state when system shutdown?

is it killed?
Zephyr ICTCloud ArchitectCommented:
As far as I understand, the service file is also touched by the shutdown command, so you can normally just leave it as is, it will shutdown the service.

You can add a timeout under [service] if you want, for example:


Open in new window

System V init  scripts run inder both upstart (ubuntu, RHEL6) and systemd (Rhel7 etc)
No need to reinvent the wheel for every system.
Nusrat NuriyevAuthor Commented:
It does not work.

When I manually start it /etc/init.d/myscript start
it works.
But it does not work on system startup.
It says something like "can't connect to mysql via socket."
It needs to require mysql/mysqld or something like that (i dont know what name is being provided in EL7)

Maybe mariadb?
What does mean "name is being provided in EL7"? name of the package?
Thats the question.
No - sysV init scripts provide facilities like $local_fs or $network
So systemD does provide something similar, but you need to look into systemd descriptor what it is.
