When I am trying to install mod_cluster in Red hate 7.3 It gives me message like

yum install mod_cluster

Loaded plugins: langpacks, product-id, search-disabled-repos, subscription-manager
No package mod_cluster available.
Error: Nothing to do

Can any one guide me how to resolve this or what is the best way to install and configure mod_cluster in Redhate 3.0 in appache httpd server.

I have already installed Apache 2.4,6 in my server.
