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

Accepted Answer

I've personally done this the other way round from @liammclennan. Some suggest that proxying through Apache defeats some of the performance and scalability advantages of Node (don't have experience myself as my server doesn't get that much traffic, but from @liammclennan's link: "Every request that comes in through Apache will cause an Apache thread to wait/block until the response is returned from your Node.js process.", which obviously doesn't mesh well with Node's architecture.)

I used node-http-proxy to set up a Node proxy server roughly as described in the first link (my Node proxy runs on port 80; Apache and my other Node services don't). Seems to be working well so far, though I have had occasional stability problems that I've 'solved' through checking the proxy's still running with a cron job (edit: it seems a lot more stable these days). The proxy's pretty lightweight, taking up about 30MB memory.

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.
