I am using an EC2 instance for the first time, I have a micro instance with my node app running using pm2

```
var express = require('express');
var app = express();
var path = require("path");
var PORT = process.env.PORT || 3000;
// Serve Static files
app.use(express.static(path.join(__dirname, 'public')));

app.listen(PORT);
console.log('%d App listening on %d', process.pid, PORT);

```

So this will run of port 3000 (is this ok?) . So i can go to `mypublicip:3000` and see my app running.

What I want to do though is go to my domain name `mydomainname.co.uk` and render the site. Domain name was purchased thorough 123 reg.

I have setup Elastic IP already, but unsure where to go from here.
