How to use HAProxy to Set up MySQL Load balancing Dec 2, MySQL, Scaling, Server optimization Ubuntu, Debian PreludeHAProxy 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.

Haproxy provides high availability, load balancing, and proxies based on TCP and HTTP applications to support virtual hosts, a free, fast, and reliable solution.
Haproxy is especially useful for Web sites that are heavily loaded, which typically require session maintenance or seven-tier processing.
