how to put nodejs and apache in the same port 80

Question

I have to put nodejs in port 80, but apache is already using it. How can I put both (nodejs and apache) on the same port 80? I need it because in my university all the ports are blocked except for PORT 80. (This is a realtime application with nodejs and socket.io (websockets) and in the other side a php application). Thanks a lot

I do this via node.js proxy..

Install http-proxy with npm or official page

Example:

var http = require('http'), httpProxy = require('http-proxy'), proxyServer = httpProxy.createServer ({     hostnameOnly: true,     router: {         'domain.com':       '127.0.0.1:81',         'domain.co.uk':     '127.0.0.1:82',         '127.0.0.1':        '127.0.0.1:83'     } });  proxyServer.listen(80); 

This creates a node process listening to port 80, and forwarding requests for domains which go to :81,82,83 etc. I recommend running this with forever and adding an entry to init.d so your proxy is up in case system shuts down.

You can also use Apache 2's mod_proxy and mod_proxy_http, which might be more reliable or perform better depending on your system.

Here's an example:

Firstly run below command to proxy to allow

sudo a2enmod proxy sudo a2enmod proxy_http sudo a2enmod proxy_balancer sudo a2enmod proxy_balancer sudo a2enmod lbmethod_byrequests  # Use Apache for requests to http://example.com/ # but use Node.js for requests to http://example.com/node/ <VirtualHost *:80>     ServerName example.com     DocumentRoot /var/www/example/     <Location /node>         ProxyPass http://127.0.0.1:8124/         ProxyPassReverse http://127.0.0.1:8124/     </Location> </VirtualHost> 

And of course you can modify the directives to your needs, such as using a different port for your virtual host (e.g., 443), different port for Node.js, or set up the proxy under a different block, such as for a subdomain (e.g., node.example.com).
