How to run nodejs with apache for ubuntu 12.04

  • Posted December 29, 2014

Hello, I’m trying to run an application in php with chat in nodejs and socket io I follow this exemple https://github.com/hmagdy/ChatNodejsZendSocketio My application has the same architecture and it works well in localhost, but i have some problem to deploy my application in the server. I’ve tried this solution http://garr.me/blog/running-node-js-and-apache-together-using-mod_proxy/ But I got a “503 Service Temporarily Unavailable” error,

My virtual host config is

<VirtualHost *:80>
    ServerAdmin admin@site.com
    ServerName test.site.com
    ServerAlias www.site.com 

    ProxyRequests off

    <Proxy *>
        Order deny,allow
        Allow from all
    </Proxy>

    <Location />
        ProxyPass http://test.site.com:8080/
        ProxyPassReverse http://test.site.com:8080/
    </Location>
</VirtualHost>

My client.js

$(document).ready(function() {
socket = io.connect('http://test.site.com:8080');
blabla

And server.js

var app = require('express').createServer()
var io = require('socket.io').listen(app);
app.listen(8080);
blabla ...

Can you please help me to figureout what i’m doing wrong. Thank you.

Generally a 503 error would mean that apache was unable to reach the nodejs service on port 8080. I would ensure that nodejs is listening and it might be worth changing your ProxyPass and ProxyPassReverse entries to use the IP address instead of the domain name to see if that resolves the problem.

Hello, I finally fix it. I change the location to my project path

<Location /path/of/my/project>
         ProxyPass http://test.site.com:8080/
         ProxyPassReverse http://test.site.com:8080/
</Location>

And to run node server.js in background i used Forever

install forever globally

npm install forever -g

Navigate to your Node.js application:

cd /path/to/your/node/app/

and run the server/main JavaScript file with forever:

forever start --spinSleepTime 10000 main.js

Where --spinSleepTime 10000 refers to the minimum uptime (in milliseconds) between launches of a crashing script. This command will work for almost all cases.

Use apache as a reverse proxy for nodejs, serves static files from apache directly. Side note: IMHO apache is not the right front end for nodejs because it is not event base I use nginx instead. AFAIK the socket.io may not work behind apache, works perfectly on nginx You will need an upgrade for http protocol somewehere and some extra header to tell node that it stays behind a reverse proxy.

telnet IP_HOST 8080
Trying IP_HOST...
telnet unable to connect to remote host: Connection refused

Hi @ryanpq, Thanks for your response. May be my question is stupid, but How can i ensure that nodejs is listening on port 8080 ?
