Background

Ubuntu 15.10

Apache/2.4.10 (Ubuntu)

Module dependencies are all enabled :

  • mod_rewrite
  • mod_proxy
  • mod_proxy_http

GitLab Community Edition 8.0.3

GitLab docroot : /opt/gitlab/embedded/service/gitlab-rails/public

I install GitLab this way : https://about.gitlab.com/downloads/#ubuntu1404

Problem

On my server I have a website running with apache2 (exemple-site.com).

I have GitLab running with the bundled nginx (exemple-gitlab.com)

I have 1 server, 1 IP, and multiple FQDN.

Like this, all my domain names are pointing to GitLab.

So exemple-gitlab.com point to GitLab as wanted but exemple-site.com point to GitLab too, and all others FQDN too.

Ways of solution

I think I have to (and I tried) to :

  • Disable the bundled nginx and configure gitlab with apache2 (hard to do for me)
  • Configure the bundled nginx as a reverse proxy of apache2 (hard to do for me)

MAJ : in fact the problem is Apache and bundled-nginx run on the same IP with the same port (80). And I don't want to run a website on port 81 or whatever, only port 80.

I prefer to use apache2 for all my PHP websites and I don't mind if gitlab use apache2 or bundled nginx, all I want is using all my FQDN for each of my websites and not all my FQDN redirectinf to gitlab.

Understanding

I don't understand how omnibus or rails or reverse proxy work.

I tried disabling bundled nginx in /etc/gitlab/gitlab.rb

nginx['enable'] = false
# For GitLab CI, use the following:
ci_nginx['enable'] = false

add www-data to gitlab-www group and modify :

web_server['external_users'] = ['www-data']

and adding a modified vhost.conf to apache2 I take it from https://gitlab.com/gitlab-org/gitlab-recipes/blob/master/web-server/apache/gitlab-apache24.conf

    <VirtualHost *:80>
    ServerName exemple-gitlab.com
    ServerSignature Off

But this conf bug my apache2 :

I found why apache2 crashed by commenting each line (damm logs were useless).

I just had to create /var/log/apache2/logs

 ErrorLog  /var/log/apache2/logs/gitlab.example.com_error.log
  CustomLog /var/log/apache2/logs/gitlab.example.com_forwarded.log common_forwarded
  CustomLog /var/log/apache2/logs/gitlab.example.com_access.log combined env=!dontlog
  CustomLog /var/log/apache2/logs/gitlab.example.com.log combined

apache2 was crashing because the folder/directory was missing ...

So now gitlab is working on is domain and my drupal too like this :

  • gitlab.com:80
  • drupal.com:80

Exactrly as I wanted :)
