    ViewVC file installation complete.
    
    Consult the INSTALL document for detailed information on completing the
    installation and configuration of ViewVC on your system.  Here's a brief
    overview of the remaining steps:
    
      1) Edit the /usr/local/viewvc-1.1.10/viewvc.conf file.
    
      2) Either configure an existing web server to run
         /usr/local/viewvc-1.1.10/bin/cgi/viewvc.cgi.
    
         Or, copy /usr/local/viewvc-1.1.10/bin/cgi/viewvc.cgi to an
         already-configured cgi-bin directory.
    
         Or, use the standalone server provided by this distribution at
         /usr/local/viewvc-1.1.10/bin/standalone.py.
    

3. Edit /viewvc.conf for your specific
configuration. In particular, examine the following configuration options:

          svn_roots (for Subversion)
          root_parents (for CVS or Subversion)
          default_root
          root_as_url_component
          rcs_dir
          mime_types_files
    
    [[email protected] ~]# vi /usr/local/viewvc-1.1.10/viewvc.conf
    
        147 ## Example:
        148 ## root_parents = /opt/svn: svn,
        149 ##                /opt/cvs: cvs
        150 ##
        151 root_parents =
        152
    

Uncomment line 151 and define the subversion root repositories.

    root_parents = /svn/repos: svn,
    

4. Locate your Apache configuration file. Typical locations are:

    /etc/httpd/httpd.conf,
    /etc/httpd/conf/httpd.conf, and
    /etc/apache/httpd.conf.
    

Depending on how Apache was installed. Configure Apache to expose ViewVC to users at the URL of your choice. Edit the apache web server config file as below:

    [[email protected] ~]# vi /etc/httpd/conf/httpd.conf
    
    565 ScriptAlias /viewvc /usr/local/viewvc-1.1.10/bin/cgi/viewvc.cgi
    566 ScriptAlias /query /usr/local/viewvc-1.1.10/bin/cgi/query.cgi
    

or if without line number, it will be as below:

    ScriptAlias /viewvc /usr/local/viewvc-1.1.10/bin/cgi/viewvc.cgi
    ScriptAlias /query /usr/local/viewvc-1.1.10/bin/cgi/query.cgi
    
    # ScriptAlias: This controls which directories contain server scripts.
    # ScriptAliases are essentially the same as Aliases, except that
    # documents in the realname directory are treated as applications and
    # run by the server when requested rather than as documents sent to the client.
    # The same rules about trailing "/" apply to ScriptAlias directives as to
    # Alias.
    #
    ScriptAlias /cgi-bin/ "/var/www/cgi-bin/"
    ScriptAlias /viewvc /usr/local/viewvc-1.1.10/bin/cgi/viewvc.cgi
    ScriptAlias /query /usr/local/viewvc-1.1.10/bin/cgi/query.cgi
    #
    # "/var/www/cgi-bin" should be changed to whatever your ScriptAliased
    # CGI directory exists, if you have that configured.
    

5. Save the httpd.conf then restart the apache server.
6. Test your http://servername/viewvc. If everything properly configured, you should see the page that lists your repositories.
