Get a VPS that offers 2 or more IP addresses.
From the WHM cPanel, find the menu item Service Configuration, select Apache Configuration and then click on Reserved IPs Editor.
Tick the IP address you DON'T WANT Apache to listen to, and write it down so you can use it in the next step. Click Save.
Install Node.js, and create a server like this:
var http = require('http');
var server = http.createServer(function(req, res) {
res.writeHead(200);
res.end('Hello, world!');
});
server.listen(80, '111.111.111.111');
Replacing 111.111.111.111 with the IP address you previously reserved from the WHM cPanel.
Stop wasting your time and never listen to those telling you to use mod_rewrite to proxy Node.js again.
Thank you so much for this, I've been trying to get this to work for a long while now especially after buying a very expensive dedicated server and found myself not able to run node.js without a port because of apache.
