Simple Cluster with Heartbeat
Following on from my previous post about setting up a reverse proxy in Fedora 10, I now delve into high availability. The plan here is to create two reverse proxy servers and cluster them together in an Active / Passive configuration with automatic fail-over. So here is our trusty network diagram: You will notice the shared IP and Proxy02 with connected to Proxy01 with the cross-over cable. You need the cross-over cable for the heartbeat keep-alive messages. As I am using VMWare I have used the HOST ONLY network configuration for the second nics on the servers thus simulating a physical cross-over cable. Here is the network configuration on each proxy server: Proxy01: eth0- ( same network and subnet as the client ) IP =192.168.0.11 SUBNET MASK=255.255.255.0 DEFAULT GW =192.168.0.1 HOSTNAME = proxy01.latham.internal eth1 - ( different network and subnet as the client ) IP = 192.168.169.11 SUBNET MASK = 255.255.255.0 DEFAULT GW = none Pr...
