I want to learn how to use Galera cluster replication (MariaDB).
- Can anyone give an advice that I can start from specific point?
- Is it compatible with vsphere?
For your first question:
Multiply Things you must know before using Galera Cluster.
It's virtually synchronized Multi-master Replication
You need minimum of 3 nodes/servers(or 2 nodes and 1 abrirator) to avoid split/brain.
So if you want to use Galera Cluster I thinks this article is good for start.
