Subversion + apache 2 (linux | debian)

Posted on June 10th, 2010 by Fred

#sudo aptitude install subversion libapache2-svn
The install should automatically enable the module.To check it:
#sudo a2enmod dav_svn
You need to configure Apache:
#sudo nano /etc/apache2/mods-enabled/dav_svn.conf
Edit the file:
<Location /svn>

  DAV svn
  SVNPath /home/svn

  AuthType Basic
  AuthName "Subversion Repository"
  AuthUserFile /etc/apache2/dav_svn.passwd
  Require valid-user
</Location>
Change /home/svn to the location of your repository.
Create the location if you haven't:
#sudo mkdir /home/svn
#sudo svnadmin create /home/svn
Make Apache the owner of the repository: 
#sudo chown -R www-data /home/svn
To secure Subversion, do the following to create a password file:
#sudo htpasswd -cm /etc/apache2/dav_svn.passwd fred
Replace fred with username you want to use, and then when prompted enter a password.
Restart Apache:#sudo /etc/init.d/apache2 restart
It's done!
Try to access: http://yourserver/svn
