Serve Git repositories with Apache

1) Install dependencies :

root# apt-get install libapache-dbi-perl libapache2-mod-perl2 libdbd-mysql-perl
root# apt-get install libauthen-simple-ldap-perl libio-socket-ssl-perl

# Then

root# mkdir /usr/lib/perl5/Apache/Authn
root# cp <redmine_root_dir>/extra/svn/Redmine.pm /usr/lib/perl5/Apache/Authn/Redmine.pm
root# a2enmod cgi

2) Then create a virtual host file :

<VirtualHost *:80>

  ServerName git.example.com

  PerlLoadModule Apache::Authn::Redmine

  SetEnv GIT_PROJECT_ROOT /data/git/repositories/
  SetEnv GIT_HTTP_EXPORT_ALL

  ScriptAlias / /usr/lib/git-core/git-http-backend/

  <Directory "/usr/lib/git-core/">
    AllowOverride None
    Options +ExecCGI -Includes
    Order allow,deny
    Allow from all
  </Directory>

  <Location />
    Order allow,deny
    Allow from all

    AuthType Basic
    AuthName "Git Repositories"
    AuthUserFile /dev/null
    Require valid-user

    PerlAccessHandler Apache::Authn::Redmine::access_handler
    PerlAuthenHandler Apache::Authn::Redmine::authen_handler

    RedmineDSN "DBI:mysql:database=db_name;host=127.0.0.1"
    RedmineDbUser "db_user"
    RedmineDbPass "db_pass"
    RedmineGitSmartHttp yes
  </Location>

  # Possible values include: debug, info, notice, warn, error, crit,
  # alert, emerg.
  LogLevel warn
  CustomLog /var/log/apache2/gitolite.access.log combined
  ErrorLog  /var/log/apache2/gitolite.error.log

</VirtualHost>

3) Your Gitolite repositories must have at least 750 permissions, if not :

root# su - git
## This can take some time
git$ find repositories/ -type f -exec chmod 640 {} \;
git$ find repositories/ -type d -exec chmod 750 {} \;

Then add www-data to git group

root# usermod -a -G git www-data

4) Then restart Apache :

root# /etc/init.d/apache2 restart

To keep 750 permissions for new repositories, edit UMASK setting in .gitolite.rc file :

root# su - git
git$ vi .gitolite.rc
## Set UMASK
UMASK                           =>  0027,
## ESC, :x

That’s all!

Use Redmine to store Git Annex repositories

1) Install git-annex on the Redmine server :

## On Debian Wheezy (with backports)
root# apt-get -t wheezy-backports install git-annex

For others distributions please refer to http://git-annex.branchable.com/install/.

2) Edit ~/.gitolite.rc to enable the git-annex-shell command. Find the ENABLE list and add this line in there somewhere :

'git-annex-shell ua',

3) Create a repo within Redmine

4) Install git-annex on your desktop (here’s ArchLinux) and follow the walkthrough, basically :

nicolas$ mkdir ~/annex
nicolas$ cd ~/annex
nicolas$ git init
nicolas$ git annex init "my desktop"
nicolas$ git remote add origin ssh://git@redmine.example.org/test.git ## The one created in Redmine
nicolas$ touch toto
nicolas$ git annex add .
nicolas$ git commit -a -m test
nicolas$ git annex sync
