hello all,
i want to run a small script which supposed to send an email when the server
1)started
2)shutdown
3)reboot

my OS :cenOS

i did following:
1)created my script and added executive permissions and copied to /etc/init.d directory
2)created symbolic links in /etc/rc5.d as K90myscript and S90myscript
when i created like above it was working fine and i am getting a mail to my email id
successfully.

i want to do the following:

1)when my system reboots i need an email alert (script should execute)
2)when my system shutdowns i need an email alert (script should execute)
for the above things i created with the above script two symbolic links to
rc6.d(for reboot purpose) and rc0.d(for shutdown purpose) and given
the links with S(start script) .

and also what i observed is that the sendmail service is stopped(K30sendmail) much before this S script(S90 script) in the above rc6.d and rc0.d directories. i think that is the only reason i am not getting the mails in the case of reboot and shutdown levels '

then how can i do it??

thanks and regards

Create symlinks in rc0.d and rc6.d with a name like K<number-less-than-30>script_name. The K doesn't necessarily mean that a service gets killed. Its means that the script gets executed with a 'stop' argument. You don't have to use the argument passed to it.

Hello agn(sorry i dunno your name),
Thanks for the reply..
and i tried as you described but its not working

i did like this
1)kept my scirpt in /etc/init.d/ dierectory
2)created symbolic link ln -s /etc/init.d/<myscript> /etc/rc0.d/K01<myscript>
3)created symbolic link ln -s /etc/init.d/<myscript> /etc/rc6.d/K01<myscript>

I have intentionally given the seqeunce name as K01 to avoid any possible chances
of stopping the dependent services .

still i am not getting the script worked.

only script i put in /etc/rc5.d/<myscript> seems to work on reboot

can u explain how to do it

thanks for the help

My guess is that the mail gets sent but the systems gets shutdown/rebooted before it leaves the system. Add 'sleep 30' to the end of the script and see if you get the mail. Also check your logs.

if you find out more about this, please post it here, i would be interested also in how to do this...


thanks in advance
