That's just the cluster resource for managing a virtual IP, not the resource for managing the httpd daemon itself.
If you've only got this resource, then there is nothing that monitors the web server. You need a cluster resource for the web server as well (ocf:heartbeat:apache, usually).
You are missing both that resource and the constraints that ensure that the virtual IP is active on the same node as the web server. The Clusters from Scratch document on the clusterlabs.org website shows you how to configure this.
