How to kill the demonized fusion passenger rails app

Using daemonize option, I execute the rails app with phusion passenger as a daemon. 

bundle exec passenger start --port 8000 --user ubuntu --daemonize

How to kill the daemonized app?

I have four processes running, but I think there might be a better way to kill all the processes to stop the daemon.

Solution

  • Killing only the master process automatically kills all the other processes.

    From the screen capture, kill -9 5702 will kill all the running processes. Even with passenger, the passenger.IP.pid file contains the pid so that you can use to kill the process.

    With passenger-status or passenger-memory-status, I can get the id so that I can kill the process. 

    ubuntu@ip-172-31-63-19 public> sudo passenger-status
