Why does a NodeJS application close after exiting the console?

Question

Node.js

I'm just starting to learn NodeJS and ran into an incomprehensible situation:
There is CentOS 6.4 with NodeJS installed.
Everything works fine, but after I run any js file through node, which "listens" on ports and processes requests to the server, and then I close the console, the script stops working.
Those. when the console is open, everything works, as soon as I do at least CTR + C or completely close the console, then everything collapses and I can again safely run the same script that just now worked with the command "node script_name.js" and it will start working again , but only until I want to close the console.
Is this normal NodeJS behavior?
How to start a web server correctly?
Perhaps the problem lies in the NodeJS settings?
Below is the actual code :)

var http = require('http');
http.createServer(function (req, res) {
  res.writeHead(200, {'Content-Type': 'text/plain'});
  res.end('Hello World\n');
}).listen(8080, 'IP СЕРВЕРА');
console.log('Server running at http://IP СЕРВЕРА:8080/');

Answer 1

Short and not very correct answer run like this
Longer answer

apt-get install upstart // yum here for Centos
------
#!upstart
description "my app"

start on started mountall
stop on shutdown

# Automatically Respawn:
respawn
respawn limit 99 5

env NODE_ENV=production

exec node /somepath/myapp/app.js >> /var/log/myapp.log 2>&1
----

Use

sudo start myapp
sudo stop myapp
sudo restart myapp

Third node-style option

$npm install forever -g
$forever start app.js

Answer 2

Yes, this is normal behavior. How else would you like it? If you want the server to hang even after your session ends, you need to run your script as a daemon.
