How to send a kill signal to stop ruby app?

Question

If you start a ruby app with the script/server command, what command do you use to stop it?

Answer 1

cat out the following file in your rails tree:

tmp/pids/server.pid

and send any variety of kill command to that pid

or simply execute the following (assuming your tree looks like: /my/rails/app

kill -9 $(cat /my/rails/app/tmp/pids/server.pid)

Answer 2

you may not have a pid file to kill if you are using a server like webrick, but you can get at it with

ps aux | grep ruby

which should show you all your ruby processes, then kill the process running the server

kill x where x is the process number

note that you will need to be running as the user running the ruby command otherwise sudo is in your future
