Apache2 ProxyPass for Rails App Gitlab

Question

I am attempting to setup a proxy with Apache2 so that incoming requests to http://myipaddress.com go to http://localhost:3000/ where I have Gitlab ( a rails app ) running. The following is what I have in my Apache configuration file on Ubuntu 10.04. I can successfully access the gitlab default page initially, but any subsequent requests performed by me by clicking on other pages after that go to a 404 NOT FOUND page. I can manually enter /gitlab/ in front of any of these failed redirects and they work just fine. How can I make this work without having to rewrite /gitlab/ after each redirect request after the initial request?

## Setup a proxy which listens on the port that gitlabh does ( from start_server.sh )
ProxyRequests Off
ProxyPass /gitlab/ http://localhost:3000/
ProxyPassReverse /gitlab/ http://localhost:3000/
#DocumentRoot /home/gitlabhq/gitlabhq/public
<Proxy http://localhost:3000/>
  Order deny,allow
  Allow from all
</Proxy>

I understand that I could have the code below , which would solve my problem. But I don't know how to modify the prefix of the gitlab rails service. I'd really appreciate some help!

ProxyPass /gitlab/ http://localhost:3000/gitlab/
ProxyPassReverse /gitlab/ http://localhost:3000/gitlab/

UPDATE:

Thanks to Friek's comment I've come very close to solving this. Below is part of my http.conf file. The only problem is when I hit the home button or the logo on the gitlab app it attempts to redirect to gitlab/ which gives me the basic index.html file from Apache2 saying 'it works!'. How can I configure this to allow me to simply got /gitlab and it takes me to the root home view of gitlab?? Thanks!

## For Gitlab using Apache2 Passenger
## Install on Ubuntu by:
## sudo gem install passenger && sudo passenger-install-apache2-module
## but only after running the install_and_configure_git.py script
## and creating a soft link to the rails gitlab /public directory like so:
## sudo ln -s /home/gitlabhq/gitlabhq/public /var/www/gitlab
LoadModule passenger_module /usr/local/lib/ruby/gems/1.9.1/gems/passenger-3.0.13/ext/apache2/mod_passenger.so
PassengerRoot /usr/local/lib/ruby/gems/1.9.1/gems/passenger-3.0.13
PassengerRuby /usr/local/bin/ruby
<VirtualHost *:80>

        ServerName gitlab

        ## Set the overall Document Root
        DocumentRoot /var/www
        <Directory /var/www>
                Allow from all
        </Directory>

        ## Set the Rails Base URI
        RackBaseURI /gitlab
        RailsBaseURI /gitlab
        <Directory /var/www/gitlab>
                Allow from all
                Options -MultiViews
        </Directory>

</VirtualHost>

I came across this gist that worked for me. In case it ever goes dead, I'll repost it.

unicorn config file

Edit file /home/gitlab/gitlab/config/unicorn.rb

Find line listen "#{app_dir}/tmp/sockets/gitlab.socket" and comment it. Uncomment line listen "127.0.0.1:8080"

required modules for apache

• sudo a2enmod proxy
• sudo a2enmod proxy_balancer
• sudo a2enmod proxy_http
• sudo a2enmod rewrite

/home/gitlab/gitlab/config/gitlab.conf

<VirtualHost *:80>
  ServerName git.domain.com

  # Point this to your public folder of teambox
  DocumentRoot /home/gitlab/gitlab

  RewriteEngine On

  <Proxy balancer://unicornservers>
    BalancerMember http://127.0.0.1:8080
  </Proxy>

  # Redirect all non-static requests to thin
  RewriteCond %{DOCUMENT_ROOT}/%{REQUEST_FILENAME} !-f
  RewriteRule ^/(.*)$ balancer://unicornservers%{REQUEST_URI} [P,QSA,L]

  ProxyPass / balancer://unicornservers/
  ProxyPassReverse / balancer://unicornservers/
  ProxyPreserveHost on

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

<VirtualHost *:80>

        ServerName gitlab

        ## Set the overall Document Root
        DocumentRoot /var/www
        <Directory /var/www>

These settings in your httpd.conf or your sites config file should do., Please remove the reverse proxy settings if you have any and try, it will work.,

if you have below lines along with above config, please remove the below lines,

ProxyPass /gitlab/ http://localhost:3000/gitlab/
ProxyPassReverse /gitlab/ http://localhost:3000/gitlab/
Proxy on

Restart your webserver

service apache2 restart
