It has been a year or so since I've done it, but yes it is doable.

A colleague of mine wrote a guide regarding it. This guide is for the 
licensed "XI" version, but the instructions should still apply to the 
"Core" version. You can find it here: https://downloads.linbit.com/ 
(titled HA Nagios XI v5 Cluster on RHEL7)

Personally, I prefer to just run the Nagios system in a VM and make that 
VM managed by a Pacemaker cluster for HA.
