Setting up svn with trac

Trac is an excellent web-based wrapper for SVN that adds bug tracking, a wiki, and several handy project management features. I keep setting up new repositories up for all the little projects we cook up in DB2 Technical Marketing, so I thought I’d write up a guide.

Installing Trac, SVN, and dav_svn for Apache2 is left as an exercise for the reader.

Create a new SVN repository:

svnadmin create /var/svn/Project

Create a new Trac environment:

trac-admin /var/trac/Project initenv

Change the owner to Apache so that it can read and write:

cd /var/svn
chown -R www-data Project
cd ../trac
chown -R www-data Project

Navigate to Apache site settings:

cd /etc/apache2/sites-enabled

If you want Trac to support multiple repositories, edit the trac file to look like this:

        DocumentRoot /usr/share/trac/cgi-bin/
                Options Indexes FollowSymLinks MultiViews ExecCGI
                AllowOverride All
                Order allow,deny
                allow from all
        Alias /var/trac/chrome/common /usr/share/trac/htdocs
                Order allow,deny
                Allow from all
        Alias /trac "/usr/share/trac/htdocs"

                SetEnv TRAC_ENV_PARENT_DIR "/var/trac"
                AuthType Basic
                AuthName "Trac"
                AuthUserFile /etc/apache2/trac.passwd
                Require valid-user

        DirectoryIndex trac.cgi
        ErrorLog /var/log/apache2/error.trac.log
        CustomLog /var/log/apache2/access.trac.log combined

The above assumes that all the repositories are in /var/trac

Navigate to Apache settings:

cd /etc/apache2/mods-enabled/

Append to dav_svn.conf:

   DAV svn
   SVNPath /var/svn/Project

   AuthType Basic
   AuthName "Subversion Repository"
   AuthUserFile /etc/apache2/dav_svn.passwd

  AuthzSVNAccessFile /etc/apache2/dav_svn.authz

    Require valid-user

The above lets you check out from http://yoursite/svn/Project

If you like, you can add a new user to dav_svn.psswd:

cd ..
htpasswd2 /etc/apache2/dav_svn.passwd NewUser

Users can then be granted permissions by editing the dav_svn.authz file. Sample file:

developers = NewUser, OtherUser
others = ThirdUser

# Restrictions on the entire repository.
# Anyone can read.
* = r
# Developers can change anything.
@developers = rw

# Other can write here
@others = rw

@others = rw

Restart Apache:

killall apache2

You now have have an Trac/SVN install with SVN at http://yoursite/svn/Project and Trac at http://yoursite/trac.cgi
