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).

MySQL 5.6 is still supported though, which means they are keeping support for core MySQL products. But if you want to get some extra performance enhancements or enterprise features for free, without getting too many bells and whistles, you might want to install Percona Server.

I’ve done this work on a new dedicated server with the latest WHM and CPanel on CentOS 7, with MySQL 5.6 installed. …

Upstart Basics for Automatic Restarts of MaxScale After Crash

Historically I do not care much about MariaDB's MaxScale, at least since I know how to build it from source when needed. But, as a support engineer who work at MariaDB, sometimes I have to deal with problems related to MaxScale, and this week it happened so that I had to explain what to do to implement automatic restarts of MaxScale "daemon" in case of crashes on RHEL 6.x.

In the process I had found out that two of my most often used Linux distributions, CentOS 6.x and Ubuntu 14.04, actually use Upstart, so good old System V's init tricks and scripts work there only partially and only because somebody cared to integrate them into this "new" …

Server monitoring with Munin and Monit on CentOS 7.2

In this article, I will describe how you can monitor your CentOS 7.2 server with Munin and Monit. Munin produces nifty little graphics about nearly every aspect of your server (load average, memory usage, CPU usage, MySQL throughput, eth0 traffic, etc.) without much configuration, whereas Monit checks the availability of services like Apache, MySQL, Postfix and takes the appropriate action such as a restart if it finds a service is not behaving as expected. The combination of the two gives you full monitoring: graphics that lets you recognize current or upcoming problems (like "We need a bigger server soon, our load average is increasing rapidly."), and a watchdog that ensures the availability of the monitored services.
