Automatic startup of WLS servers when booting Linux

On the My Oracle Support website you can find the article "RC Initialization Scripts for Starting and Stopping WebLogic Server as a UNIX Daemon [ID 877902.1]".
Here in this post, I will describe an alternative method.
I tested out on a Oracle Linux 6 host machine.
These are the steps that must/can be performed:

(1)
Create for each server within your domain a boot.properties file (My Oracle Support: "How to Start a WebLogic 10.3.x Domain AdminServer Without Interactively Supplying the Username / Password? [ID 980292.1]").


(2)
Login as root


(3)
Navigate to /etc/init.d and create a file wls with this content:

#!/bin/bash
#
# oracle Init file for starting and stopping WLS
#
# chkconfig: 35 80 30
# description: Oracle WLS startup script
# Source function library

. /etc/rc.d/init.d/functions

ORACLE_OWNER="oracle"
DOMAIN_HOME="/opt/oracle/Oracle/Middleware/user_projects/domains/dev_domain"

case "$1" in
start)
echo -n $"Starting WLS:"
su - $ORACLE_OWNER -c "$DOMAIN_HOME/bin/startWebLogic.sh > /dev/null 2>&1 &"
su - $ORACLE_OWNER -c "$DOMAIN_HOME/bin/startManagedWebLogic.sh ManagedServer1 > /dev/null 2>&1 &"
su - $ORACLE_OWNER -c "$DOMAIN_HOME/bin/startManagedWebLogic.sh ManagedServer2 > /dev/null 2>&1 &"
echo "OK"
;;
stop)
echo -n $"Stopping WLS:"
su - $ORACLE_OWNER -c "$DOMAIN_HOME/bin/stopManagedWebLogic.sh ManagedServer1"
su - $ORACLE_OWNER -c "$DOMAIN_HOME/bin/stopManagedWebLogic.sh ManagedServer2"
su - $ORACLE_OWNER -c "$DOMAIN_HOME/bin/stopWebLogic.sh"
echo "OK"
;;
*)
echo $"Usage: $0 {start|stop}"
esac

In a terminal window, execute these commands:

chmod 750 /etc/init.d/wls
chkconfig --add wls --level 0356
