Mike T. and Erin O.


The MySQL Server open source relational database system (RDBMS) is widely used as the storage backend for dynamic web sites and applications. In many areas it has become a mission-critical component of the software stack, where downtime is not an option. There are many ways to ensure the availability of a MySQL Server and how to provide redundancy and fault-tolerance.

In this talk, Lenz Grimmer (blog ( / twitter ( will give an overview about some best practices and commonly used HA solutions and technologies for MySQL. The talk will cover the commonly used Open Source components and tools, primarily focusing on Linux.

The session will start with a brief introduction to High Availability (HA), the terminology and general concepts involved. Afterwards, several MySQL HA solutions and technologies will be introduced and explained, e.g. MySQL replication (and possible topologies), block device replication (DRBD), Shared storage/SAN, Linux-Heartbeat/Pacemaker, MySQL Cluster, MySQL Proxy and other clustering solutions.
