I have installed heartbeat, got it started fine. Now I need to set a cluster IP address, in a simple configuration. Basically one server should take over that address in the event the other goes down. The servers reach an application that’s backend is an already clustered mysql server, so all I need is just the IP address.
However, I am a bit confused at this point about setting this up. Currently the machines both have 2 NICs. The addresses are as follows:
Suse11A: eth0/192.168.2.225/24 eth1/192.168.1.10/24
Suse11B: eth0/192.168.2.226/24 eth1/192.168.1.11/24
I would like to set a cluster address to 192.168.2.210/24. Reading through the config documentation, I thought I needed to add the following line to haresources:
Suse11A IPAddr::192.168.2.210/24/eth0
I think the problem I am having is how I would continue further setting up the eth0 for this address? I thought that the heartbeat IPAddr script would automatically assign an IP alias…correct? Yet 192.168.2.210 is not found, so obviously I have not set this up correctly somewhere. My log is as follows:
