Hi all, I am using Folsom, and I want to set up a HA between VMs. For example, I have two DB VMs. One is the primary and other is a slave. I want to use Keepalive or pacemake to switch between them when one is failed.
But how to implement this? Because in general, we need a dynamic IP to associate to the VMs and change the relationship when necessary. But which IP should be used ? Floating ip or Fixed IP? and how. -- Lei Zhang Blog: http://jeffrey4l.github.com twitter/weibo: @jeffrey4l
