When developing a project, you may want to keep a version control of all your files so that you can easily revert to an earlier page (or the previous revision) to fix any bugs or in the event that someone accidentally deleted your files.
In Ubuntu, the easiest way to do version control is to set up a Subversion (SVN) server.
Install SVN and Apache
sudo apt-get install subversion libapache2-svn
Next, we are going to create a directory to hold your repository.
sudo svnadmin create /var/lib/svn
Give apache the access right to the repository
sudo chown -R www-data:www-data /var/lib/svn
sudo chmod 770 -R /var/lib/svn
Configure Apache for SVN access
gksu gedit /etc/apache2/mods-available/dav_svn.conf
Uncomment the codes by removing the ‘#’ in front of the following lines:
<Location /svn>
…
DAV svn
…
AuthType Basic
AuthName “Subversion Repository”
AuthUserFile /etc/apache2/dav_svn.passwd
…
<LimitExcept GET PROPFIND OPTIONS REPORT>
Require valid-user
</LimitExcept>
</Location>
If you have only one repository for your SVN, uncomment the following line
SVNPath /var/lib/svn
Else if you are setting up multiple repositories, uncomment this line
SVNParentPath /var/lib/svn
Remember that at any time, only SVNPath or SVNParentPath is uncommented. Do not uncomment both at the same time.
Create a password for your username
sudo htpasswd -cm /etc/apache2/dav_svn.passwd yourusername
Restart apache
sudo /etc/init.d/apache2 restart
Now open your browser and go to http://localhost/svn. If you see the following, the your installation is successful.

Importing your project into SVN
You have successfully installed and configured SVN, now we need to import our project files to the SVN.
sudo apt-get install rapidsvn
Go to Applications->Programming->RapidSVN
In the RapidSVN, go to Repository->Import
In the window, enter the following:

Click OK. Enter your username and password. Your project should be in the SVN now.
