Setup dns for the virtual ip, then setup Corosync before starting with this guide.

HA-proxy is short for High Availibility proxy. It has features to check that the servers behind it are up, and round robins incoming requests between the servers. HA-proxy can be used with various server types. We will configure two HA-proxys, which later will be running an active/passive setup with Corosync
