Question

how do I route multiple domains to multiple node applications?

I'm used to the typical lamp web hosting environment where you just click a few buttons in cpanel and your domain gets zoned and mapped to a folder within htdocs. I've been using node.js a lot and it doesn't seem as simple to do the same thing. If I had multiple node apps and I wanted to route domain1.com:80 and domain2.com:80 each to its own node app and port, how do I go about doing that? where do I start?

apache
node.js
nginx

Answer 1

This is typically done with nginx. Nginx is a reverse proxy, a piece of software you put infront node.js.

server {
    listen      80;
    server_name www.domain1.com;
    root /var/www/domain1;

    location / {
        proxy_pass http://localhost:1337; # this is where your node.js app_domain1 is listening
    }
}

server {
    listen       80;
    server_name www.domain2.com;
    root /var/www/domain2;

    location / {
        proxy_pass http://localhost:1338; # this is where your node.js app_domain2 is listening
    }
}

I dont recomend apache to do these, nginx fits better with nodejs.

You can run the apps for example at the port 3000 and 3001,

then proxy it to mydomain1:80, and mydomain2:80.

To get mydomain1 and mydomain2 unther the port 80, these is all about DNS not apache.

Theres no way to run apache/nginx and your node httpserver on the same port. ull get a error.

p.s. Im not sure in u can do these @tipical lamp webhost

hope it helps

You can setup virtual domains in Node if you're using Express.

The code you would use to start your server with would look something like this.

var sys = require('sys'),
  express = require('express');

var app = express.createServer();

app.configure(function() {
  app.use(express.vhost('subdomain1.local', require('./subdomain1/app').app));
  app.use(express.vhost('subdomain2.local', require('./subdomain2/app').app));
  app.listen(3000);
});

Then you would export app in each subdomain.

var app = express.createServer();
exports.app = app;
