Node.js and Apache: connection issues

I have installed Node.js with Socket.io on a CentOS server which is running Apache on port 80. I created a socket test, which justs listens on port 8080.

If I curl the address localhost:8080 from within the server's shell, I get the Socket.io-welcome message. If I have a line like this:

<script src="http://localhost:8080/socket.io/socket.io.js"></script>

Then the browser cannot find the file.

A "solution" was to proxy requests to /nodejs/ to http://localhost:8080/, but this solution did not work for very long.

Is it possible to run the Node.js server when we have Apache installed? Which settings must be changed in order for us to access the url: http://server.com:8080 ? It seems the Node.js only accepts connections from localhost.

Problem is most probably in your node.js program. It should listen on 0.0.0.0 and not 127.0.0.1 which is local only.

So where you've got something like:

.listen(8080, '127.0.0.1'); // '127.0.0.1' or 'localhost'

You should change it to:

.listen(8080); // or 0.0.0.0

Apache will only interfere if it also uses port 8080 but you should get an error when starting your node app if this is the case.

Also, if you connect to http://localhost in your browser, it will only work if the server is on the same local machine as the browser. Fine for testing I guess.

You'll have to connect to a domain or ip address if you have a hosted server else no browser will find it.

Update: Your socket.io code also needs to connect correctly:

var socket = io.connect('http://correct.server.com:8080'); // not localhost

and your browser needs to load the javascript file from the correct place:

<script src="http://correct.server.com/socket.io/socket.io.js"></script> // not localhost

This might help with firewall / load balancer issues:
