How to get viewvc working with Apache httpd and Fedora and subversion (svn)

1. Get subversion working with httpd first. (See http://muddyazian.blogspot.com/2013/05/how-to-start-subversion-repository-over.html)
2. yum install viewvc viewvc-httpd
3. Edit /etc/viewvc/viewvc.conf and modify the svn_roots and root_parents options.
4. Edit /etc/httpd/conf/httpd.conf and add in the following:
   
   <Directory /usr/lib/python2.7/site-packages/viewvc/bin/mod_python>
     Order allow,deny
     Allow from all
     AuthType Basic
     AuthName "Subversion repositories"
     AuthUserFile /etc/svn-auth-users
     Require valid-user
   </Directory>
   
   <Directory /usr/share/viewvc/templates/docroot>
     Order allow,deny
     Allow from all
   </Directory>
   
   
   
   ...
   
   Alias /viewvc-static "/usr/share/viewvc/templates/docroot/images"
   
   
   
   ...
   
   ScriptAlias /viewvc /usr/lib/python2.7/site-packages/viewvc/bin/cgi/viewvc.cgi
   ScriptAlias /query /usr/lib/python2.7/site-packages/viewvc/bin/cgi/query.cgi
   
   
5. Restart the web server: /sbin/service httpd restart
6. Go to http://localhost/viewvc
7. If you haven't already done so, create the /etc/svn-auth-users file:
   
   htpasswd -cm /etc/svn-auth-users firstUsername
   New password:
   Re-type new password:
   Adding password for user firstUsername
   

You can test things out (sanity check) like this:

/usr/lib/python2.7/site-packages/viewvc/bin/standalone.py -r /path/to/svn/repository/location

Then in firefox, go to http://localhost:49152/viewvc
