• confFile - configuration file or object. Only PID_FILE and http.numWorkers are used at the moment
• masterSettings - See http:https://nodejs.org/api/cluster.html#cluster_cluster_setupmaster_settings
• callback - function which will be called when master has forked workers

• callback - will call when worker has attached listener on exit signal
• cleanupCallback - will call when worker receives exit signal. It pass a function for terminating process (or you can choose to exit).

You need to create a symbolic link /etc/init.d/pstarter to pstarter/etc/init.d/pstarter and make pstarter executable. You need also specify NODE_BIN, SERVER, PID_FILE, NODEJS and NODE_ENV if your application uses it:

• NODE_BIN folder which contains SERVER
• SERVER application/server file to execute
• PID_FILE should be /var/run/pstarter.pid in production linux
• NODEJS executable nodejs
• NODE_ENV for your own application; normally development/production

sudo /etc/init.d/pstarter start

sudo /etc/init.d/pstarter restart

sudo /etc/init.d/pstarter graceful

sudo /etc/init.d/pstarter force-restart

sudo /etc/init.d/pstarter stop
