To set up a service in your linux system to start, stop, and restart SHRINE (Tomcat), you can template a file within /etc/init.d called 'shrine':
Code Block | ||||
---|---|---|---|---|

#!/bin/bash
#
# Based on a script by valotas: https://gist.github.com/valotas/1000094#file-tomcat-sh
#
# This shell script takes care of starting and stopping Tomcat for SHRINE
#
# chkconfig: - 80 20
#
### BEGIN INIT INFO

# Required-Start: $network $syslog
# Required-Stop: $network $syslog
# Default-Start:
# Default-Stop:
# Description: Release implementation for Servlet 2.5 and JSP 2.1
# Short-Description: start and stop tomcat
### END INIT INFO

tomcat_pid() {

pid=$(tomcat_pid)
echo "$pid" > /var/run/shrine.pid
echo "SHRINE is running (pid: $pid)"

return 0
}
stop() {

if [ -n "$pid" ]
then

let kwait=$SHUTDOWN_WAIT

until [ `ps -p $pid | grep -c $pid` = '0' ] || [ $count -gt $kwait ]
do
echo -n -e "\nwaiting for processes to exit";
sleep 1
let count=$count+1;

if [ $count -gt $kwait ]; then

kill -9 $pid

else
echo "SHRINE is not running"
fi
;;

echo $"Usage: [sudo] $0 {start|stop|restart|status}"
exit 1

esac
exit $RETVAL |
After creating this file, you can then start, stop, and restart SHRINE anywhere by running:
