I wrote a java application, want to register it as a service, so wrote a bash script in /etc/init.d/
. Here is the script:
#!/bin/sh
#
# chkconfig: 345 50 83
#
### BEGIN INIT INFO
# Short description: Trigger Beamer on system startup
# Description: Trigger blupay beamer on system start up
### END INIT INFO
#Source function library
. /etc/rc.d/init.d/functions
#targets beamer config file
if [ -f /etc/sysconfig/beamer ]; then
/etc/sysconfig/beamer
fi
#start httpd in the C locale by default.
BEAMER_LANG=${BEAMER_LANG-"java"}
# Path to beamer.
beamer=/home/blupayss/Desktop/BeamerApp
prog=beamer
pidfile=${PIDFILE-/var/run/httpd/beamer.pid}
lockfile=${LOCKFILE-/var/lock/subsys/beamer}
RETVAL=0
start() {
echo -n "starting $prog"
LANG=${BEAMER_LANG}
RETVAL=$?
java -jar ${beamer}/Beamer.jar
echo
[ $RETVAL = 0 ] && touch ${lockfile}
return $RETVAL
}
stop() {
echo -n $"Stopping $prog: "
killproc -p ${pidfile} -d $beamer
RETVAL=$?
echo
[ $RETVAL = 0 ] && rm -f ${lockfile} ${pidfile}
}
reload() {
echo -n $"Reloading $prog: "
if ! LANG=$BEAMER_LANG $beamer $OPTIONS -t >&/dev/null; then
RETVAL=6
echo $"not reloading due to configuration syntax error"
failure $"not reloading $beamer due to configuration syntax error"
else
# Force LSB behaviour from killproc
LSB=1 killproc -p ${pidfile} $beamer -HUP
RETVAL=$?
if [ $RETVAL -eq 7 ]; then
failure $"beamer shutdown"
fi
fi
echo
}
# See how we were called.
case "$1" in
start)
start
;;
stop)
stop
;;
status)
status -p ${pidfile} $beamer
RETVAL=$?
;;
restart)
stop
start
;;
force-reload|reload)
reload
;;
*)
echo $"Usage: $prog {start|stop|restart||force-reload|reload|status}"
RETVAL=2
esac
exit $RETVAL
When I execute it as sudo service beamer start
, then java applicaition gets launched successfully. However it returns an error:
/etc/sysconfig/beamer: Permission denied
How can I make my script access /etc/sysconfig/beamer
?
/etc/sysconfig/beamer
? Considering the directory name and position in the script I suppose you actually want to source it./etc/sysconfig/beamer
fixed it, thank you
