Deploy Ruby

#Since Ruby will run in the console you may want to use screen to keep the app running in the background once you disconnect. 
#To do this first install screen
apt-get install screen

#Then start a new screen session
screen -S "My App"

#and run your app within the session
ruby myapp.rb

#Opt: Kill all ruby process
killall ruby

#Opt: You can quit a screen without attaching to it. First, find its session and then quit it.
screen -ls
screen -X -S [session # you want to kill] quit
