[SOLVED] Help inittab problem

[Linpuskelvin]

Can someone help me!

1. I am using CentOS 5.4 and I try to use inittab at the etc/inittab to initiate a program at startup

2. Below is my script and saved as heritrix.sh
#!/bin/bash

export HERITRIX_HOME=/root/heritrix-1.14.3
cd $HERITRIX_HOME
chmod u+x $HERITRIX_HOME/bin/heritrix
$HERITRIX_HOME/bin/heritrix --admin=LOGIN:PASSWORD --port=9090

3. I did the chmod +x for the permission already.

4. I not confirmed whether it is running at startup.

5. the script is no problem as I have check it

That's not how you get a program to run at startup. You absolutely DO NOT want to modify /etc/inittab except to tell it what runlevel to boot into (id:N:initdefault unless you REALLY know what you are doing, otherwise you may "brick" your system. There are a couple of ways to do what you want.

1. Add the initialization/termination of your application to /etc/rc.d/rc.local. That is the script the system uses to start/stop user-space services.
2. Add a script to each run-level (/etc/rc.d/rcN.d where N is the run-level) to start/stop the service.

Option one is the better one since the second one requires determining what run-levels you want to start your service at, and you have to decide where in the order of service startup/shutdown yours should go. Plus there may be other scripts or files you will have to deal with. Services that are specified in rc.local, they are started after all other services are started at boot and shutdown before other services are terminated when the system is shutdown/restarted. Here is the run-level 5 script for CUPS, the printer management system that is a good template for you to use:

#!/bin/sh

exit $RETVAL

I hope this helps.
