Running socket.io on Shared Hosting

问题

I am using a shared hosting server from A2Hosting where I want to run a socket.io server (application), here is what I have done so far:

SSH'ed into server
Installed node
Run / started the socket.io server (application)

var server = require('http').createServer(),
    io = require('socket.io')(server),
    port = 58082;

server.listen(port, my - domain - name);

But my client (the browser) can't connect to the server.

I have tried running the same socket.io sever (application) on a local Linux machine and I was able to successfully connect via the browser, so the issue lies in the configuration of the shared hosting server.

You're almost there. The one thing missing is the integration of your socket.io application with the webserver. For that you will need a .htaccess file to redirect the incoming requests.

Create a .htaccess file in the public_html directory and add the snippet below. Replace the XXXXX with an unused port anywhere between 49152 and 65535, those are the ones available. If your application won't start, try a different port.

RewriteEngine On
RewriteRule ^$ http://127.0.0.1:XXXXX/ [P,L]
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ http://127.0.0.1:XXXXX/$1 [P,L]
