Hi, Not that I would know of a HOWTO for this specific setup, but it is quite simple: - corosync takes care of the cluster communication - pacemaker does the management of the resources. Resources: - ldirectord clone runs on both nodes of the cluster - VIP address managed by the cluster in that way that it only runs on a node with a ldirectord-clone instance (colocation and order) - In a LVS setup with NAT make a group of VIP and DIP. Advanced setup: Make a cluster like the setup above but also make the apache run on these two machines. Use the localnode feature of LVS to realize the complete setup with two machines instead of four. This configuration is left as an exercise for the reader.
