GIT – In this article we will see how you can create Git repositories under . This article will not teach you on how to use Git, it will only cover the installation and configuration of Git and Gitweb on , plus showing you how to use Apache with Gitweb.

  • Dedicated user for Git repos
  • SSH will be used for commits
  • Enable gitweb for web access (Apache will be used)
  • Anonymous cloning using the Git protocol

For those who don’t know what Git is:

You should know how to use Git before reading on.

 devel/git . Select GITWEBSVNP4, and CVS are optional. Deselect them if you don’t plan to use them.

Create a git user with uid and gid as 9418:

# pw groupadd -n git -g 9418
# pw useradd -n git -u 9418 -g git -c git -d /git -s /usr/local/libexec/git-core/git-shell -h -

The git-shell is used for this user, and home is set as /git/. The repos will be under /git/base/.

Make sure the permissions of the directory are correct and create /git/base/:

# chown git:git /git/
# chmod 755 /git
# mkdir /git/base/
# chown git:git /git/base/
# chmod 775 /git/base/

Next, add users to the git group to be able to create repositories under /git/base/. This isn’t necessary for users who only need commit access.

# vi /etc/group
...
git:*:9418:user1,user2

We’ll be using SSH keys for authenication, so collect the public keys of all the users who need commit access. Then, put the public keys into the right place:

# mkdir /git/.ssh/
# chmod 700 /git/.ssh/
# touch /git/.ssh/authorized_keys
# chmod 600 /git/.ssh/authorized_keys
(Put the public keys into authorized_keys, one per line)
# chown -R git:git /git/.ssh/

Everything should be set now. Let’s create a repo for testing (change to a user that has been added to the git group and has commit access).

$ mkdir /git/base/test.git
$ cd /git/base/test.git && git init --bare --shared

Create a local repo and commit:

$ mkdir ~/test
$ cd ~/test && git init
$ echo '123456' > foo
$ git add .
$ git commit

Now push it into the remote repo (remember to replace git.example.com with your own hostname):

$ git remote add origin git@git.example.com:base/test.git
$ git push origin master

Don’t delete the test repo yet.

Since the git repo should be up and working by now, let’s enable gitweb for web access. Apache’s VirtualHost will be used for this.

Copy gitweb files to /home/www/git/:

$ cp /usr/local/share/examples/git/gitweb/git* /home/www/git/

Modify Apache settings (change the ServerName and the access and error log paths as necessary):

<VirtualHost *:80>
  ServerAdmin webmaster@yourhostname
  DocumentRoot "/home/www/git"
  ServerName git.example.com
  ErrorLog "/path/to/errolog"
  CustomLog "/path/to/accesslog" combined

  <Directory "/home/www/git">
    Options ExecCGI
    Order allow,deny
    Allow from all

    DirectoryIndex gitweb.cgi
    AddHandler cgi-script .cgi
  </Directory>
</VirtualHost>

Now edit gitweb.cgi:

-our $projectroot = "/pub/scm";
+our $projectroot = "/git/base";
...
-our $home_link_str = "projects";
+our $home_link_str = "base";
...
-our $site_name = ""
+our $site_name = "git.example.com"
...
-our $home_text = "indextext.html";
+our $home_text = "content.html"; (Leave empty if unnecessary)
...
-our $projects_list_description_width = 25;
+our $projects_list_description_width = 40; (Give the description a bit more space)

Change the $site_header, $home_text, and $site_footer as needed.

Open up your browser and check if it’s working.

You might notice that the description of the test repo hasn’t been modified yet. You might also want to change the owner.

For the description, edit /git/base/test.git/description. Put this into /git/base/test.git/config to change the owner:

[gitweb]
        owner = Your Name

Only the Git protocol isn’t working now.

Add this to /etc/rc.conf:

git_daemon_enable="YES"
git_daemon_directory="/git"
git_daemon_flags="--syslog --base-path=/git --export-all"

Start the daemon:

# /usr/local/etc/rc.d/git_daemon start

You should now be able to clone using the Git protocol. Try it out:

$ cd /tmp/
$ git clone git://git.example.com/base/test.git

One last thing. You might want to list URLs for cloning repos on the summary page of test.git in gitweb. Just add this line (the url line) to the[gitweb] section of /git/base/test.git/config:

[gitweb]
        owner = Your Name
        url = git://git.example.com/base/test.git

This line can appear more than once if there are multiple URLs:

[gitweb]
        owner = Your Name
        url = git://git.example.com/base/test.git
        url = git@git.example.com:base/test.git
