Create a file under /etc/init.d/ called jboss

chmod 755 jboss
vi /etc/init.d/jboss and add the following text :

#!/bin/sh

export JBOSS_HOME=/opt/jboss-as-web-7.0.2.Final/

case “$1” in
start)
echo “Starting JBoss AS 7.0.2”
sudo -u jboss sh ${JBOSS_HOME}/bin/standalone.sh -b 0.0.0.0 > /dev/null 2>&1 &

;;
*)
echo “Usage: /etc/init.d/jboss {start|stop}”
exit 1
;;

exit 0

with standalone.sh -b 0.0.0.0 means that jbossis binded on all ip’s

chkconfig –add jboss && chkconfig jboss on

vi /etc/hosts and add the hostname

yum install java-1.7.0-openjdk.x86_64

tar xzvf jboss-as-7.0.2.Final.tar.gz

mv jboss-as-7.0.2.Final jboss-as

adduser jboss

chown jboss:jboss /opt/jboss-as

add the following lines to jboss .bash_profile :

JAVA_HOME=/usr/lib/jvm/java-1.7.0-openjdk-1.7.0.9.x86_64

JBOSS_HOME=/opt/jboss-as

export JAVA_HOME

export JBOSS_HOME

cd /opt/jboss-as/bin

You must type “unset MODULEPATH” beacuse it’s in conflict with default MODULEPATH environment.

./standalone.sh and jboss should start correctly
