OpenSuse Inittab – How to Add Item to Inittab on OpenSuse 12.1?

initopensusestartup

I am currently working on a project which needs to be added to inittab so that the program loads during startup.

The program that I am trying to start is a c# mono application. I have created a start script and if the start script is run manually the program launches fine. However, when I put it into inittab the program doesn't launch.

I've checked in /var/log/messages but it doesn't say anything is wrong, it just says that it is reloading.

Below is what I have added to my inittab script

bes:2345:respawn:/home/bits/MyProgram/start.myprogram

Thanks for any help you can provide

UPDATE
Below is the code in the start script which is located in /home/bits/MyProgram.

#!/bin/sh

cd /home/bits/MyProgram

/usr/bin/mono EmailServer.exe "$@"

I have also tried adding > mylog.txt onto the end of the line beginning with /usr/bin/mono e.g.

/usr/bin/mono EmailServer.exe "$@" > mylog.txt

If I run the start script manually, even if I am not in the directory where the start script is located it works fine, its just when I add it to inittab and run telinit q it never starts and the log isn't written to but the log does get written to if I start the program manually.

Thanks for any help you can provide.

The problem is simple, you are using OpenSuse 12.1 which uses systemd instead of your classic System V boot system.

To install a new service place create following file in /etc/systemd/system/myprogname.service

[Unit]
Description=My progname service file

[Service]
ExecStart=/home/bits/MyProgram

[Install]
WantedBy=multi-user.target

Aftwards run systemctl daemon-reload and systemctl start myprogname.service

If you want to automatically restart MyProgname you have to add

Restart=restart-always

to the service section.

Add After=mysql.service to your service file (or change it to the correct service name), e.g:

[Unit]
Description=Boardies Email Server Startup Script
After=mysql.service

[Service]
ExecStart=/home/bits/EmailServer/start.email
Restart=always

[Install]
WantedBy=multi-user.target

Please note that you don't have to put your service file into /lib/systemd/system, it is a user provided file and you should only copy it to /etc/systemd/system.

To get a list of all service files you can use systemctl list-unit-files and determine the correct name for your database service (it is probably either mysql.service or mysqld.service)

Debian – How to start an application automatically on boot

Here's the excerpt from http://www.debian-administration.org/articles/28 which seems to answer your question.

Note: In the example script below just add a call to the "start)" section to actually launch your program. You can test the script's functionality without rebooting the system: call it with the full path and giving it a parameter of "start" or "stop"

Here goes:

Debian uses a Sys-V like init system for executing commands when the system runlevel changes - for example at bootup and shutdown time.

If you wish to add a new service to start when the machine boots you should add the necessary script to the directory /etc/init.d/. Many of the scripts already present in that directory will give you an example of the kind of things that you can do.

Here's a very simple script which is divided into two parts, code which always runs, and code which runs when called with "start" or "stop".

#! /bin/sh
# /etc/init.d/blah
#

# Some things that run always
touch /var/lock/blah

# Carry out specific functions when asked to by the system
case "$1" in
  start)
    echo "Starting script blah "
    echo "Could do more here"
    ;;
  stop)
    echo "Stopping script blah"
    echo "Could do more here"
    ;;
  *)
    echo "Usage: /etc/init.d/blah {start|stop}"
    exit 1
    ;;
esac

exit 0

Once you've saved your file into the correct location make sure that it's executable by running "chmod 755 /etc/init.d/blah".

Then you need to add the appropriate symbolic links to cause the script to be executed when the system goes down, or comes up.

The simplest way of doing this is to use the Debian-specific command update-rc.d:

root@skx:~# update-rc.d blah defaults
 Adding system startup for /etc/init.d/blah ...
   /etc/rc0.d/K20blah -> ../init.d/blah
   /etc/rc1.d/K20blah -> ../init.d/blah
   /etc/rc6.d/K20blah -> ../init.d/blah
   /etc/rc2.d/S20blah -> ../init.d/blah
   /etc/rc3.d/S20blah -> ../init.d/blah
   /etc/rc4.d/S20blah -> ../init.d/blah
   /etc/rc5.d/S20blah -> ../init.d/blah
