- Create users and add them to a group. There are a bunch of different ways to do this. I am only showing you how to create a group.
- Make a directory to house the repository.
- Create the repository.
svnadmin create /var/lib/project
- Change permissions to allow the group read/write access.
chgrp svn-users db db/transactions db/write-lock db/revs db/revprops hooks locks
chmod 2770 db db/transactions db/revs db/revprops
chmod 660 db/write-lock
chmod 750 hooks
chmod 770 locks
If your clients are on Windows, I recommend using TortoiseSVN.
