bash-script: how to start the prozess one after another
Hi all,
I have an auto startup script (to start the Jboss) under /etc/init.d/myScript and looks as follow:
-rwxr-xr-x 1 root root 4334 Oct 5 14:33 /etc/init.d/mtext
Code:
#!/bin/bash
#
# $Id: jboss_init_redhat.sh 99350 2010-01-13 17:05:27Z bshim $
#
# JBoss Control Script for mtext
#
# chkconfig: 3 98 02
# description: jboss mtext
# To use this script run it as root - it will switch to the specified user
#
# Here is a little (and extremely primitive) startup/shutdown script
# for RedHat systems. It assumes that JBoss lives in /usr/local/jboss,
# it's run by user 'jboss' and JDK binaries are in /usr/local/jdk/bin.
# All this can be changed in the script itself.
#
# Either modify this script for your requirements or just ensure that
# the following variables are set correctly before calling the script.
#JAVA_OPTS="-Djboss.messagingServerPeerID=1"
#JBOSS_USER=`basename $0`
JBOSS_USER=mtext
. /home/$JBOSS_USER/.bash_profile
#define where jboss is - this is the directory containing directories log, bin, conf etc
JBOSS_HOME=${JBOSS_HOME:-"/usr/local/jboss"}
#define the user under which jboss will run, or use 'RUNASIS' to run as the current user

Here one can see this script is going to start teh Jboss first. Then sleep 180 sec and start the second prozess. Then sleep 10 sec and start the third prozess.
This script is not execute from root but from each non-root user with command
Code:
/etc/init.d/myScript
