MySQL Cluster is a high-availability, high-redundancy version of MySQL adapted for the distributed computing environment. It uses the NDB Cluster storage engine to enable running several MySQL servers in a cluster. This storage engine is available in MySQL 5.1 binary releases and in RPMs compatible with most modern Linux distributions.

The operating systems on which MySQL Cluster is currently available are Linux, Mac OS X, and Solaris. (Some users have reported success with running MySQL Cluster on FreeBSD, although this is not yet officially supported by MySQL AB.) We are working to make Cluster run on all operating systems supported by MySQL, including Windows, and will update this page as new platforms are supported.

This chapter represents a work in progress, and its contents are subject to revision as MySQL Cluster continues to evolve. Additional information regarding MySQL Cluster can be found on the MySQL AB Web site at http://www.mysql.com/products/cluster/.
