Subversion with web access on ubuntu

May 25, 2008 at 7:26 pm · Filed under subversion, ubuntu ·Tagged , ,

I will take you through on how to install subversion with web access using apache module, which can be achieved through simple steps.

Installing subversion

sudo apt-get install subversion libapache2-svn

Creating repository

sudo svnadmin create /svnrepo

Editing web module configuration

I have used gedit for editing. You can use any editor of your choice

sudo gedit /etc/apache2/mods-enabled/dav_svn.conf

The Element in the configuration file indicates the root directory where the subversion will be accessible from. For example, if you are accessing the subversion as http://localhost/svn, the Location element will look like this.

<Location /svn>

Uncomment the DAV line to enable webdav module

# Uncomment this to enable the repository,DAV svn

Set the SVNPath line to the repository directory which you created in the beginning.

SVNPath /svnrepo

The next section is the Authentication to access subversion. This is just a basic authentication, so it is not considered to be very secure. Uncomment the following lines and leave it unchanged.

# Uncomment the following 3 lines to enable Basic AuthenticationAuthType BasicAuthName "Subversion Repository"AuthUserFile /etc/apache2/dav_svn.passwd

Create Users

c – creates new user.
m – md5 encryption

sudo htpasswd -cm /etc/apache2/dav_svn.passwdNew password:Re-type new password:Adding password for user

Adding permissions to repository

sudo chown -R www-data:www-data /svnrepo

Restart Apache

To reflect the changes made, restart the apache sever using the following command.

sudo /etc/init.d/apache2 restart

Access the url

Now access the url, you must be now able to browse the subversion repository.

http://localhost/svn
