If you created a simple init script below /etc/init.d, which gets started, but not stopped on reboot or system halt, this article is for you.


I assume you ensured that the chkconfig information in the script is correct and that you ran chkconfig $name on. The output of chkconfig should look like this:

[root@kvm-hw-snr01 ~]# chkconfig --list  | grep kvm-vms
kvm-vms         0:off   1:off   2:on    3:on    4:on    5:on    6:off
[root@kvm-hw-snr01 ~]# 

Although this looks correct, there is a small block in /etc/rc.d/rc that prevents your init script from being called on stop:

# First, run the KILL scripts.
for i in /etc/rc$runlevel.d/K* ; do

        # Check if the subsystem is already up.
        [ -f /var/lock/subsys/$subsys -o -f /var/lock/subsys/$subsys.init ] || continue
        check_runlevel "$i" || continue

        # Bring the subsystem down.
        [ -n "$UPSTART" ] && initctl emit --quiet stopping JOB=$subsys
        $i stop
        [ -n "$UPSTART" ] && initctl emit --quiet stopped JOB=$subsys

So only if your script creates /var/lock/subsys/yourscriptname or /var/lock/subsys/yourscriptname.init, it will be called on stop.


You can include the following three lines into your script to get your script stopped:


# In the start block
touch "$broken_lock_file_for_centos"

# In the stop block
rm -f "$broken_lock_file_for_centos"
