  <VirtualHost *:80>
      ServerName <YOUR DOMAIN NAME>
      ProxyRequests Off
      ProxyPreserveHost On
      ProxyVia Full
      <Proxy *>
          Require all granted
      </Proxy>
      <Location />
          ProxyPass http://localhost:<YOUR PORT>/
          ProxyPassReverse http://127.0.0.1:<YOUR PORT>
      </Location>
  </VirtualHost>

• Navigate to your nodejs app

  $ cd ~/path/to/your/nodeapp/app.js

• Add following in the app.js file:

   var http = require('http');
   http.createServer(function (request, response) {
      response.writeHead(200, {'Content-Type': 'text/plain'});
      response.end('Node.js is running from site1.\n');
   }).listen(8080);
   console.log('Server running at http://127.0.0.1:8080/');

• Goto the terminal, and type

  $ cd ~/path/to/your/nodeapp/
  $ node app.js
