, see https://access.redhat.com/documentation/en/red-hat-jboss-core-services-apache-http-server/version-2.4/apache-http-server-installation-guide/That documentation should contain the location of all important files (e.g. the config file needed in step 2) and should also say how to start/configure mod_cluster. From my experience, just installing the package does not automatically configure mod_cluster as the default load balancer, so I guess there's still some configuration required.

Only then, after mod_cluster is properly installed and configured, can user proceed with steps 2-4.
