How to run process as background and never die? This is an old question, but is high ranked on Google. I almost can't believe on the highest voted answers, because running a node. Specially the screen/tmux solution, which should really be considered an amateur solution. Screen and Tmux are not meant to keep processes running, but for multiplexing terminal sessions. It's fine, when you are running a script on your server and want to disconnect.
But for a node. js server your don't want your process to be attached to a terminal session. This is too fragile.
To keep things running you need to daemonize the process! There are plenty of good tools to do that. PM2: http: //pm. 2.
