Startup Script for IHS on RHEL

Today I'm going to show you how to setup IHS to run after boot/reboot on RHEL.

• First you need to know what is your default runtime level. To determinate default level see your inittab file:
• [root@ic ~]# less /etc/inittab
• find line start with id:< some number >:initdefault:
• In my case I have level 3 as default:
• id:3:initdefault:
• As root, create a new file ihs in  /etc/init.d/
• [root@ic ~]# vim /etc/init.d/ihs 

#!/bin/bash

# SERVICENAME should match this filename

SERVICENAME=$(basename $0)

LOCKFILE="/var/lock/subsys/${SERVICENAME}"

APACHECTL=/opt/IBM/HTTPServer/bin/apachectl

# The next lines are for chkconfig on RedHat systems.

# chkconfig: 2345 98 02

# description: Starts and stops IHS 

case "$1" in

  start)

    touch $LOCKFILE 

    ;;

  stop)

    rm -f $LOCKFILE

    ;;

  *)

    echo "Usage: $0 {start|stop|status|restart}"

    exit 1

    ;;

esac

$APACHECTL "$@"

• Save file and add executable mark to be able to run the script:
• [root@ic ~]# chmod u+x /etc/init.d/ihs
• Now add new service and set up if to run on level 3
• [root@ic ~]# chkconfig --add ihs
• [root@ic ~]# chkconfig --level 3 ihs on
