Here is a list of tasks to remind me how to manage my SVN virtual machine:
sudo svnadmin create /var/svnroot/myrepo (substitute myrepo with whatever name you want)
Add a user:
In the folder for the repository you just created, go into the “conf” folder. You then need to edit the “passwd” file
Setup authorization to use the passwd file:
Edit 'svnserve.conf' in the same conf folder; uncomment the 'passwd-db = passwd'
Create directory structure /trunk /branches /tags in a new temporary folder and import this structure into the repository via a right click on the folder and selecting TortoiseSVN → Import… This will import your temp folder into the repository root to create the basic repository layout.
Now you are ready to go.
