How to Replace MySQL with Percona Server on a CPanel, WHM VPS or Dedicated Server

In this blog post, we’ll look at how to replace MySQL with Percona Server for MySQL on a CPanel, WHM VPS or dedicated server.

In general, CPanel and WHM have been leaning towards support of MariaDB over other flavors. This is partly due to the upstream repos replacing the MySQL package with MariaDB (for example, on CentOS).
