Node.js Question

Permanent socket.io server on Ubuntu Linux

I'm starting a socket.io server by entering a command:

node server.js

But that sometimes stops, or I need to have a terminal window open for it to run.

How can I set this up on a Linux server (Ubuntu) so there is a permanent server running in the system (like Apache) and if it stops it restarts automatically?


You can use PM2

after install the npm package you can use pm2 command line :

pm2 start server.js

You can use too nodemon or forever to detect when your server files changed. It will restart automatically your server and you don't need anymore to stop / start your node application.

Note than pm2 is used for production and nodemon for development
