Here is a good link that explains how SVN can be installed and configured. Seems like it can be up and running in less than 10 minutes. Boy, that's in a jiffy.
Steps roughly are like this:
a. yum install subversion mod_dav_svn
b. Configure httpd.conf for servername / other port details [if required]
c. Modify subversion.conf [under httpd/conf.d/ directory] and do the required changes.
Mine looks like this:
# SVNParentPath /var/www/svn
# # Limit write permission to list of valid users.
# <LimitExcept GET PROPFIND OPTIONS REPORT>
# # Require SSL connection for password protection.
# # SSLRequireSSL
# AuthName "Authorization Realm"
AuthName "Subversion repos"
d. htpasswd -cm /etc/svn-auth-conf <desiredusername>
e. For all subsequent entries into svn-auth-conf, don't use -c option. Just -m should suffice. [If required, optional step]
f. Configure repository: mkdir svn (create a directory called svn under /var/www [or the location that you specified in the subversion.conf. Note that location and directory name should match in subversion.conf and the actual path. )
g. cd svn [or the directory that you just created]
h. svnadmin create repos
i. chown -R apache.apache repos
j. restart httpd server [apachectl -k restart or service httpd restart]
Done. Finished. Kaput.
