Making an RC Script on Linux

[scottalanmiller]

Often we need to build our own RC scripts which can be managed via the chkconfig command but we don’t know where to start. Here is a blank framework that simply needs to be filled out in order to work. Once completed, just put into /etc/init.d and use “chkconfig -add scriptname” to enable it.

#!/bin/sh
#
# name          This shell script takes care of starting and stopping
#               the "name" services.
#
# chkconfig: - 60 20
# description: Fill in description
# probe: true
# config: If there is a config file
 
RETVAL=0
uid=`id | cut -d\( -f1 | cut -d= -f2`
 
# See how we were called.
case "$1" in
  start)
                # Start the process
                # Only root can stop the service
                [ $uid -ne 0 ] && exit 4
                ;;
  stop)
                # Stop the process
                # Only root can stop the service
                [ $uid -ne 0 ] && exit 4
                ;;
  status)
                # Check on app
                ;;
  restart)
                $0 stop
                $0 start
                ;;
  *)
                echo $"Usage: nfs {start|stop|status|restart}"
                RETVAL=2
                ;;
esac
 
exit $RETVAL
