One of the things I want to try out is running multiple MySQL instances on the same machine. The concept remained in the back of my mind ever since I attended Ryan Thiessen’s …

Installing MySQL on CentOS 6.2 with PaceMaker, MHA and more

When I work with High Availability software, I’m reminded of the maze in the original computer adventure game “You are Lost in a maze of twisty-turny passages all alike…”.

If you search the web for HA programs you will find many well maintained projects all related that refer each other. The goal of this document is to give you with a step by step guide to a production worthy MySQL system. It should provide at least 99.999% access to your data and be able to scale read requests as …

The State of High Availability

Searching for the Holly GrailFor months I have been writing and rewriting an blog post called “The Full Monty”. It’s a kind of how to build complete production system from scratch. I’m still not done. Maybe I’m fullish thinking I can build a one type fits all database server. But that’s not the problem.

Working with replication, you come across many topologies, some of them sound and established, some of them less so, and some of them still in the realm of the hopeless wishes. I have been working with replication for almost 10 years now, and my wish list grew quite big during this time. In the last 12 months, though, while working at Continuent, some of the topologies that I wanted to work with have moved from the cloud of wishful thinking to the firm land of things that happen.
