In the apache config you want to specify a MapCacheAlias, this should be 
to a non-existent directory as apache will use this path to handoff the 
request to the mapcache service handler. For example:

MapCacheAlias /mapcache /usr/var/mapcache/mapcache.xml

When mapcache gets the handoff it reads the mapcache.xml config file 
which defines the various services, grids, etc that you have configured.

If you have enabled the demo service for example:

http://localhost/mapcache/demo

Then mapcache will generate an html page the list the configured 
services. And if you click on one of the servers like wms if you 
configured that, it will generate a sample OpenLayers application 
preconfigured to access that service. You can view the page source to 
see how to setup OpenLayers to access that service.
