How to install a local copy of git.gnome.org

This tutorial will show you how to create a local copy of the git.gnome.org website.

Pre-Requisites

Apache/httpd - How to install Apache/httpd on Fedora
cgit - Clone the repo (http://git.zx2c4.com/cgit) or install it directly from your Package Manager (sudo yum install cgit on Fedora)

Steps

1. Get the GNOME Grass theme for cgit

Using a Terminal, run the following command: git clone git://git.gnome.org/reponame
This will clone the code for the GNOME Grass theme for cgit from the GNOME repository.
You may clone the theme to any folder, just remember where it is. You're going to need the path in the next steps.

2. Configure a VirtualHost

Configure a VirtualHost at /etc/httpd/sites.d/my-vhost.conf or /etc/apache2/sites-available/my-vhost-conf.
Here's an example of a my-vhost.conf configuration (Pay attention to the paths that you need to change):

my-vhost.conf

<VirtualHost *:80>
    ServerName git.gnome.org

    DocumentRoot /path-to-the-directory-where-the-css-is
    CustomLog  /var/log/httpd/access_log  combined env=!dontlog
    ErrorLog  /var/log/httpd/error_log

    <Directory /path-to-cgit.cgi-file>
        Options +ExecCGI
    </Directory>
</VirtualHost>

[For Debian or Ubuntu] Using a Terminal, run the following command: ln -s /etc/apache2/sites-available/my-vhost.conf /etc/apache2/sites-available/my-vhost.conf - Symbolic Link

3. Setting up cgit

Copy the following content to cgit's configuration file at /etc/cgitrc.
Make sure the paths for css, header and footer match the path for your CSS directory.

/etc/cgitrc

# GNOME customization
css=/browse/cgit-gnome.css
# No logo, GNOME header is already logified
logo=

# Has GNOME header and footer
header=/srv/http/cgit/gnome.header
footer=/srv/http/cgit/gnome.footer

favicon=http://www-old.gnome.org/img/logo/foot-16.png

commit-filter=/usr/local/bin/cgit-commit-links.sh
source-filter=/usr/local/bin/cgit-syntax-highlighting.sh

# Looks funny if we don't have something here, maybe could be improved
root-title=All Projects
# Looks fine without a description though
root-desc=

clone-prefix=git://git.gnome.org http://git.gnome.org/browse ssh://USERNAME@git.gnome.org/git

# Put all the modules on the first page of the project listing without pagination
max-repo-count=655

# List the number of files and lines changed in the log
enable-log-filecount=1
enable-log-linecount=1

# Allow download of tar.gz, tar.bz2 and zip-files
snapshots=tar.gz zip
