I have the backup agent running on this server and it's Redhat Linux Advance Server 2.1.

1. What do I need to do in order for this service startup automatically everytime I reboot the server.

2. Do I have the write scripts in Linux????

3. If I have to write scripts, how do I start, is there any good books or resource for me to learn???

thanks so much for all of the help in the past.

Go into your /etc/init.d, in there are scripts to stop/start/restart processes. Open one up and look at it. It looks some thing like this:

#! /bin/sh
# /sbin/init.d/runlevel.3

case "$1" in
start)
need runlevel.2
need portmap
mount -vat nfs
;;
stop)
umount -vat nfs
;;
esac
# End

You can add the command to start the service under start and the command to stop the service under stop and even add a restart command. Then you'll need to add this to a run level. I believe that 3 should do. Then if you wanted to restart the service, you could type /etc/init.d/backupagent restart.

to start the backup agent, I can simply type:

uagent start


do you mean that I can simply add this commnand in anywhere on the mentioned file???


thanks

I believe that this will work.

#! /bin/sh
# /sbin/init.d/runlevel.3

case "$1" in
start)
uagent start
;;
stop)
uagent stop
;;
restart)
uagent restart
;;
esac
# End

Then you will have to add it to the runlevel that you want. I use slack and am not really sure exactly how RH runlevels work. I think that they are in the /etc/rc.d/rc.x, where x is 1 to 6. If you look around on the net you will find out exactly what you need to do.

If it's just one command that you want to run on boot (for example uagent), just append the line to your /etc/rc.local file.

This ought to do the trick.
# echo "uagent start" >> /etc/rc.local

... of, do it the traditional way and edit /etc/rc.local with an editor


Cheers
