Centos – How to adapt this debian init.d script to work with CentOS 5

git-daemon under Debian is managed by runit.

sv stop git-daemon

should do it.

The command "doesn't complete" because the daemon function does not run your application in the background for you. You will need to add an & to the end of your daemon command like so:

daemon --user someproguser $exec &

If someprog doesn't handle SIGHUP, you should run the command with nohup to ensure that your process won't receive SIGHUP which tells your process to exit when the parent shell exits. That would look like this:

daemon --user someproguser "nohup $exec" &

In your stop function, killproc "exec" isn't doing anything to stop your program. It should read like so:

killproc $exec

killproc requires the full path to your application to stop it properly. I've had some trouble with killproc in the past, so you can also just kill the PID in the PIDFILE you should be writing someprog's PID to with something like this:

cat $pidfile | xargs kill

You can write the PIDFILE like this:

ps aux | grep $exec | grep -v grep | tr -s " " | cut -d " " -f2 > $pidfile

where $pidfile points to /var/run/someprog.pid.

If you want [OK] or [FAILED] on your stop function, you should use the success and failure functions from /etc/rc.d/init.d/functions. You don't need these in the start function because daemon calls the appropriate one for you.

You also only need quotes around strings with spaces. It's a style choice, though, so it's up to you.

All these changes look like this:

#!/bin/bash
#
#   /etc/rc.d/init.d/someprog
#
# Starts the someprog daemon
#
# chkconfig: 345 80 20
# description: the someprog daemon
# processname: someprog
# config: /etc/someprog.conf

# Source function library.
