How to run Apache and Node.js together (the right way)

how-to-run-apache-and-node.js-together-the-right-way.markdown

Step 1

Get a VPS that offers 2 or more IP addresses.

Step 2

From the WHM cPanel, find the menu item Service Configuration, select Apache Configuration and then click on Reserved IPs Editor.

Step 3

Tick the IP address you DON'T WANT Apache to listen to, and write it down so you can use it in the next step. Click Save.

Step 4

Install Node.js, and create a server like this:

var http = require('http');

var server = http.createServer(function(req, res) {
  res.writeHead(200);
  res.end('Hello, world!');
});

server.listen(80, '111.111.111.111');

Replacing 111.111.111.111 with the IP address you previously reserved from the WHM cPanel.

Step 5

Stop wasting your time and never listen to those telling you to use mod_rewrite to proxy Node.js again.

@jeffmcneill Ah, that's interesting. So the space will only be depleted when you get a failed alloc for single IPv4. Please do keep us posted.

I do not know if this is "the right way", but I strongly disagree with the agressiv post of "@tcrebbs".
He is accusing the author of this gist of running node as a root service to use reserved port 80. Of course, this is stupid to run node as root. Node can use port 80 without running as root. There are two solutions. You can either use "setcap 'cap_net_bind_service=+ep' /usr/bin/nodejs" or use iptables (see http://stackoverflow.com/questions/16573668/best-practices-when-running-node-js-with-port-80-ubuntu-linode).

In both cases, you avoid the performance penalty of apache proxy (this may be important) at the cost of an additional ip address. Instead of religions, it is better to understand the advantages and disadvantges of the different technical possibilities before choosing solutions.

Hey I made a Youtube Video that implements your gist. https://www.youtube.com/watch?v=3U1AkjlWymI&feature=youtu.be

following article also describes a way to do this without mod_rewrite on same VPS.
https://wathmal.me/blog/run-apache-with-node-js-reverse-proxy/

solve my problem, and @mojaray2k video implement was really clear.
we dont need to rebuild or install another mod on WHM and mod_rewrite concept, I can't take the risk if my Cpanel going error.

FYI if you want to express require module together with http module, simply using this code
/*****************************/
var app = express();
var http = require('http');
/* pur some apt.set here /
/ pur some apt.use or express static configurations here /
/ pur some apt.get here */
app.server = http.createServer(app);
app.server.listen(80, '111.111.111.111'); // change 111.111.111.111 with your reserve IP

If you have apache you can add this in your Apache config file:
ProxyPass /node http://localhost:8000/
Asuming 8000 is the port where node is listening.

Thank you so much for this, I've been trying to get this to work for a long while now especially after buying a very expensive dedicated server and found myself not able to run node.js without a port because of apache.

The disadvantage to use proxyPass is that you can't use host property to do something related with subdomains, base uri namespace, etc. This will be localhost:{port}

this wont works for https 443 port also gets blocked

Thank you @lancasterjones your way worked for me :-).
This can be added to apache /etc/apache2/sites-enabled/000-default.conf before the ending.

Eg

<VirtualHost *:80>
        # The ServerName directive sets the request scheme, hostname and port that
        # the server uses to identify itself. This is used when creating
        # redirection URLs. In the context of virtual hosts, the ServerName
        # specifies what hostname must appear in the request's Host: header to
        # match this virtual host. For the default virtual host (this file) this
        # value is not decisive as it is used as a last resort host regardless.
        # However, you must set it for any further virtual host explicitly.
        #ServerName www.example.com

        ServerAdmin webmaster@localhost
        DocumentRoot /var/www/html/iot-platform-frontend

        # Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
        # error, crit, alert, emerg.
        # It is also possible to configure the loglevel for particular
        # modules, e.g.
        #LogLevel info ssl:warn

        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined

        # For most configuration files from conf-available/, which are
        # enabled or disabled at a global level, it is possible to
        # include a line for only one particular virtual host. For example the
        # following line enables the CGI configuration for this host only
        # after it has been globally disabled with "a2disconf".
        #Include conf-available/serve-cgi-bin.conf
ProxyRequests on
ProxyPass /node http://localhost:8080
</VirtualHost>
