HAProxy is an open source software which can load balance HTTP and TCP servers. In the previous article on HAProxy we configured load balancing for HTTP and in this one we’ll do the same for MySQL.

This makes it suitable for tasks such as caching the results of duplicate MySQL queries. In this article, memcached will be installed as a MySQL plugin and tightly integrated into MySQL. It will provide a NoSQL style access layer for managing information directly in regular MySQL InnoDB tables.
