How to make a node.js application run permanently?
On a Debian server, I installed Node.js. I understand how to launch an app from putty with this command line:
node /srv/www/MyUserAccount/server/server.js
and get to it on the address 50.51.52.53:8080 (IP and port).
But as soon as I close putty, then I cannot reach the address 50.51.52.53:8080 anymore.

As you can guess, I am a beginner with Linux and Node.js.
Answer
You could install forever using npm like this:
sudo npm install -g forever
And then start your application with:
forever server.js
Or as a service:
forever start server.js
Forever restarts your app when it crashes or stops for some reason. To restrict restarts to 5 you could use:
forever -m5 server.js
To list all running processes:
forever list
Note the integer in the brackets and use it as following to stop a process:
forever stop 0
Restarting a running process goes:
forever restart 0
If you're working on your application file, you can use the -w parameter to restart automatically whenever your server.js file changes:
forever -w server.js
