Redhat chkconfig script: does the 'stop' ever run?

[LBertoglio]

Hi all.
It seems that the "stop" part of some scripts listed in chkconf on my redhat AS 4.4 are never executed (but some are).
To show this, i created a test script, /etc/init.d/leo :
#!/bin/bash
# chkconfig: 345 99 01
# description: leonardo test
# source function library
. /etc/init.d/functions
case "$1" in
start)
echo -n "starting leonardo"
echo "$(date): $1" >/tmp/leo_start
;;
stop)
echo -n "stopping leonardo"
echo "$(date): $1" >/tmp/leo_stop
;;
*)
echo -n "others leonardo"
echo "$(date): $1" >/tmp/leo_others
exit 1
esac
exit 0
#########
Then I did: chmod 755, chown root:root,
chkconfig --add leo.
ll /etc/rc?.d/*leo*
.../etc/rc6.d/K01leonardo -> ../init.d/leonardo
.../etc/rc5.d/S99leonardo -> ../init.d/leonardo
.../etc/rc4.d/S99leonardo -> ../init.d/leonardo
.../etc/rc3.d/S99leonardo -> ../init.d/leonardo
.../etc/rc1.d/K01leonardo -> ../init.d/leonardo
.../etc/rc0.d/K01leonardo -> ../init.d/leonardo
Also 'chkconfig --list leonardo' give the expected output.
This script works fine when is executed from the command line with start|stop|SmthingElse parameters.
But after a reboot of the server, I just can find a /tmp/leo_start file, and a "starting leo" line in /var/log/messages, but NEVER a /tmp/leo_stop or a "stopping leo" message, nor a mail for root, or smthing like that.
So it seems that the script is never executed by the system with a "stop" parameter when the server is rebooted. And that the K01leonardo links are unuseful...
What am I missing???
Many thanks in advance to everybody.
Leonardo.

A typical UNIX system deletes everything in /tmp folder upon boot. Many Linux sysadmins choose to do the same with script or other means.
I'd recomend you to use another folder for your tests.

No: /tmp contains also old files. Anyway I moved the files creation to /root/leo_xxx, but nothing changed: just the start file appeared after reboot.
Thanks anyway.

How do you reboot the server?

[LBertoglio]

With the "reboot" or "shutdown -r now" commands. No differences found using the first or the 2nd one....
/sbin/reboot is a link to halt.

Ciao Leonardo,

usually when you use chkconfig, the script is copied into /etc/init.d and configured for start/stop into rc.x level.

Check if into /etc/init.d your script is present.

excuse me, bad read!

Sorry


when you reboot the server, the tmp folder became empty.
When you shutdown the system, it go into runlevel 0 and have to kill all the process.
Your script write into tmp the "leo_stop" but this is erased at reboot, infact you can find only the start.


Try to put your start/stop result into another folder and reboot, i'm sure you can find all.

Hi,
file creation changed to /root ; and anyway /tmp is not emptyed at boot, so it seems. And yes, the script "leo" is in /etc/init.d.
But no good news after the reboot.
Some other suggestions?
Many thanks.
Leonardo.

Hm,
what happens if you execute:
/etc/rc0.d/K01leonardo ?

I suppose it should bring you closer to the solution, i.e. if it'll create the /tmp/leo_stop file, then (unless it's a bug of course) you should consider rewriting your script to create a file in another folder.

Hi.
Running as root
/etc/rc0.d/K01leonardo stop
works fine, and create the /root/leo_stop file (as the "new" script version has /tmp changed in /root).
But after the 'shutdown -r now' command is completed, in /root just the leo_start exists. Nothing changed, no leo_stop file!
