[mmattel]

This is a small description for Ubuntu how to create scripts allowing usual start/stop commands including an upstart.

Kill any runnng instances

ps aux | grep redis-stat
#get pid from output
kill $PID

sudo vi /etc/init.d/redis-stat
#fill in following contetnt

exit 0

Set the upstart

sudo chmod +x /etc/init.d/redis-stat
sudo update-rc.d redis-stat defaults

Run the usual service command

sudo service redis-stat start|stop|reload|restart|force-reload|status
