I'm trying to configure a HA system on a network of virtual machines (and then on a real one).
I found that what I need is to use Pacemaker (clusterlabs.org).
Unfortunately the documentation is a bit cryptic for people like me that have no experience with these technologies.
I'm wondering if there is someone that can suggest me a very simple tutorial for configuring a simple cluster (3-4 nodes max) with only one service (e.g. http).
Then I can go on by myself :)
