How to run Node js on VPS?

Question

Node.js

Tell me how to run node.js server on VDS.
On the local everything is simple according to the instructions

var http = require('http');
http.createServer(function (req, res) {
res.writeHead(200, {'Content-Type': 'text/plain'});
res.end('Hello World\n');
}).listen(3030 );
console.log('Server running on port 3030.');

And then we open http://localhost/3030 and see the work
I do the same on the VPS, I get the answer in the console "Server running on port 3030" but nothing opens at this address

Answer 1

http://your.server.ip.address:3030;

Answer 2

This was not the problem here, but for the future - many services listen only to the local interface by default.
Check in Linux - "netstat -nlp", in FreeBSD - "sockstat -4l".
