The Apache configuration must be modified in order to enable Keystone files to be processed by the PHP module. Edit the file httpd.conf.

First, the page type index.tkl must be added to the list of files for the DirectoryIndex directive. Example:

      <IfModule mod_dir.c>
      DirectoryIndex index.html index.php ... index.tkl
      </IfModule>
    

Second, the tkl-handler must be set. Add the following two lines inbetween the mod_actions brackets. (If your redhat configuration does not have the mod_actions brakcets, you can add those lines somewhere near the other AddHandler lines)

    <IfModule mod_actions>
      AddHandler tkl-handler .tkl
      Action tkl-handler /tklite/shell.php
      ...
    </IfModule>
    

Make sure the last line reflects the actual location of the shell script relative to the document root of the server.
