Node.js + Socket.io + Apache

Question

I\'m looking for a way to integrate Node.js + Socket.io + Apache in the following way: I want apache to continue serving HTML / JS files. I want node.js to listen for connec

Answer 1

Serve your static content from Apache port 80 and serve your dynamic/data content over a Socket.IO server on port 8080. You don't need the app = require('http').createServer(handler) in your Socket.IO app

Apache port 80 |-------------| clients |------------| Socket.IO port 8080

var io = require('socket.io').listen(8080);

io.sockets.on('connection', function (socket) {
  io.sockets.emit('this', { will: 'be received by everyone'});

  socket.on('clientMSG', function (from, msg) {
    console.log('I received a private message by ', from, ' saying ', msg);
  });

  socket.on('disconnect', function () {
    sockets.emit('user disconnected');
  });
});

Answer 2

AWS + APACHE + NODEJS + SOCKET.IO + ANGULARJS

SERVER SIDE
This worked for me on a production server running apache on port 80 and NodeJS on port 8000. Change the NodeJS port by your desired option…

1. Create a folder named “nodejs” for the files of the NodeJS server at /var/www/html
2. Run Nodejs on a different port than 80, for example port 8000
3. Execute command: a2enmod proxy_http
4. Execute command: a2enmod proxy_wstunnel

5. Put the next 2 lines at the end of the following file: /etc/apache2/apache2.conf

   LoadModule proxy_module /usr/lib/apache2/modules/mod_proxy.so
   LoadModule proxy_http_module /usr/lib/apache2/modules/mod_proxy_http.so 
   

6. Put the next 12 lines at the end of the following file: /sites-available/000-default.conf
   (If you have a different site created by you, put the lines there)

   RewriteEngine On
   RewriteCond %{REQUEST_URI}  ^socket.io          [NC]
   RewriteCond %{QUERY_STRING} transport=websocket [NC]
   RewriteRule /{.*}       ws://localhost:8000/$1  [P,L]
   
   RewriteCond %{HTTP:Connection} Upgrade [NC]
   RewriteRule /(.*) ws://localhost:8000/$1 [P,L]
   
   ProxyPass /nodejs http://localhost:8000/
   ProxyPassReverse /nodejs http://localhost:8000/
   
   
   ProxyPass /socket.io http://localhost:8000/socket.io
   ProxyPassReverse /socket.io http://loacalhost:8000/socket.io
   
   ProxyPass /socket.io ws://localhost:8000/socket.io
   ProxyPassReverse /socket.io ws://localhost:8000/socket.io
   

7. sudo service apache2 restart

CLIENT SIDE
I use the following library to implement Socket.io in AngularJS, but I think this guide
is useful too for a basic Javascript implementation of socket.io technology.

To call my PHP server: example.com
To call NodeJS server: example.com/nodejs
To call NodeJS Socket: example.com <---this call will be done by default by the library

I hope help you!
