I’ve been working with Glassfish
recently, from the system administration point of view. First task,
after getting a good build with Maven (doing it with basic rpm methods
netted me a massive dependency list, including things like Firefox!),
was to write an init script so that Glassfish can be integrated into
the CentOS boot sequence.
Because we might have multiple domains set up inside of Glassfish, I
opted for a setup similar to the Tomcat5 init script - check the
basename of $0, and use that to determine which domain to boot up. The
fiddling in start() gets around the fact that Glassfish doesn’t seem to
write a PID file out where we need one.
So, just in case anyone else needs to do this:
#!/bin/bash
# chkconfig: 2345 85 15
# description: GlassFish is a Java Application Server.
# processname: glassfish
# pidfile: /var/run/glassfish.pid
# source function library
. /etc/init.d/functions
RETVAL=0
GLASSFISH_BIN="/var/lib/glassfish/bin"
# Basename works with symbolic links.
NAME="$(basename $0)"
unset ISBOOT
# Trim off the Sxx/Kxx prefix
if [ "${NAME:0:1}" = "S" -o "${NAME:0:1}" = "K" ]; then
NAME="${NAME:3}"
ISBOOT="1"
fi
# Trim off the glassfish- prefix
NAME=${NAME:10}
# /etc/init.d/glassfish should never be called directly.
if [ -z $NAME ]; then
echo -n $"Cannot start Glassfish without specifying a domain."
failure
echo
exit 1
fi
start() {
echo -n $"Starting Glassfish V2 domain $NAME: "
daemon --user glassfish --pidfile /var/run/glassfish-$NAME.pid "$GLASSFISH_BIN/asadmin start-domain $NAME >/dev/null 2>&1"
RETVAL=$?
if [ $RETVAL -eq 0 ]; then
PID=`ps U glassfish | grep $NAME | awk '{ print $1}'`
echo $PID > /var/run/glassfish-$NAME.pid
touch /var/lock/subsys/glassfish-$NAME
fi
echo
}
stop() {
echo -n $"Shutting down Glassfish V2 domain $NAME: "
$GLASSFISH_BIN/asadmin stop-domain $NAME >/dev/null 2>&1
RETVAL=$?
[ $RETVAL -eq 0 ] && rm -f /var/lock/subsys/glassfish-$NAME && rm -f /var/run/glassfish-$NAME && success || failure
echo
}
case "$1" in
start)
start
;;
stop)
stop
;;
restart|reload)
stop
start
;;
condrestart)
if [ -f /var/lock/subsys/glassfish-$NAME ]; then
stop
start
fi
;;
status)
status glassfish-$NAME
RETVAL=$?
;;
*)
echo $"Usage: $0 {start|stop|restart|condrestart|status}"
exit 1
esac
exit $RETVAL
The alternative is to define a /etc/sysconfig/glassfish file, and
insert a variable with the list of domains to boot, in sequence. This
is a little harder to manage automatically in Puppet,
but might be a better solution if precise boot sequences are required
(this method will boot in sequence based on the S numbers in the base
script, and then the alphabetical ordering of the names).
