I have 2 nginx web servers on Ubuntu20.4 serving WordPress sites that use MariaDB for the databases. What is the best setup for High Availability? I have seen this post ... how-to-set-up-nginx-high-availability-with-pacemaker-corosync-and-crmsh-on-ubuntu-1604 I think this takes care of the Nginx side? Then this post... tutorial/ubuntu-drbd-heartbeat-high-availability It will do the Mariadb HA. Would I just do both setups to get the desired results? Or would I change something in one or the other maybe combine things?
