after installing all needed rpms about apache2 and php4, just open /etc/apache2/httpd.conf and add following two lines on bottom to make UserDir and Alias work:
Include /etc/apache2/mod_userdir.conf
Include /etc/apache2/conf.d/*
UserDir permit you to use /home/
Alias permit to use any directory on you server for publish contents.
For more infos, consult apache documentation or contact me!
