Setting up JBoss as a Linux Service

[duncangroenewald]

Can anyone provide the necessary scripts for running JBoss as a service under Linux (Red Hat v9). Sorry am not a Linux expert (yet!) and its not quite the same as setting up a service under NT.

I have tried the following script file to set up an RmiJdbc server (just to keep things simple to start with) - but the daemon function never seems to return - it blocks. Is there some way of getting the VM to start and provide a return code ?

I was hoping this would work and I could use the same approach to start JBoss !! Its never that simple is it !!

#!/bin/bash
#
# /etc/rc.d/init.d/rmijdbc
#
# Starts the rmijdbc server
#
# chkconfig: 345 95 5
# description: database server
# processname: rmijdbc

# Source function library.
. /etc/init.d/functions

#test -x /usr/sbin/rmijdbc || exit 0

RETVAL=0

RJ_HOME=/home/duncan/apps/bin
#JAVA_HOME=/usr/java/j2sdk1.4.2
PB_HOME=/home/duncan/apps/pointbase
PATH=$PATH:$JAVA_HOME/bin
RJ_CLASSPATH=/home/duncan/data/java:$PB_HOME/lib/pbembedded45GA217.jar:$CLASSPATH

OPTS="-server -classpath $RJ_CLASSPATH -Djava.rmi.server.hostname=dunxpc org.objectweb.rmijdbc.RJJdbcServer -port 9091 com.pointbase.jdbc.jdbcUniversalDriver"


#
# See how we were called.
#

prog="rmijdbc"

start() {
# Check if rmijdbc is already running
if [ ! -f /var/lock/subsys/rmijdbc ]; then
echo -n $"Starting $prog: "
daemon $JAVA_HOME/bin/rmijdbc $OPTS
RETVAL=$?
[ $RETVAL -eq 0 ] && touch /var/lock/subsys/rmijdbc
echo
fi
return $RETVAL
}

stop() {
echo -n $"Stopping $prog: "
killproc $JAVA_HOME/bin/rmijdbc
RETVAL=$?
[ $RETVAL -eq 0 ] && rm -f /var/lock/subsys/rmijdbc
echo
return $RETVAL
}


restart() {
stop
start
}

reload() {
restart
}

status_at() {
status /usr/sbin/atd
}

case "$1" in

if [ -f /var/lock/subsys/atd ]; then

This is a pretty simple init.d script. You can tidy it up a bit, I guess. Call the script /etc/init.d/jboss and use chkconfig to install it so the service starts and stops in the right startup and shutdown sequence when booting and shutting down the OS. "man chkconfig" for more details. I execute run.sh as a background process and look for the JBoss process found with "IBMJava2" - the test could be better constructed and is no guarantee for operation, but it takes a couple of minutes to start JBoss so I don't particularly want to hold up the OS boot process. I'm sure you can polish it up.

#!/bin/sh
#
# chkconfig: - 91 35

# Source function library.
if [ -f /etc/init.d/functions ] ; then
. /etc/init.d/functions
elif [ -f /etc/rc.d/init.d/functions ] ; then
. /etc/rc.d/init.d/functions
else
exit 0
fi

# Avoid using root's TMPDIR
unset TMPDIR

Hi

You can consider using Wrapper (http://wrapper.sourceforge.net) which is applicable for other platforms also.
