A MySQL server that is part of a MySQL Cluster differs in one chief respect from a normal (nonclustered) MySQL server, in that it employs the
NDBCLUSTERstorage engine. This engine is also referred to simply as
NDB, and the two forms of the name are synonymous.
To avoid unnecessary allocation of resources, the server is configured by default with the
NDBstorage engine disabled. To enable
NDB, you must modify the server's
my.cnfconfiguration file, or start the server with the

The MySQL server is a part of the cluster, so it also must know how to access an MGM node to obtain the cluster configuration data. The default behavior is to look for the MGM node on
localhost. However, should you need to specify that its location is elsewhere, this can be done in
my.cnfor on the MySQL server command line. Before the
NDBstorage engine can be used, at least one MGM node must be operational, as well as any desired data nodes.
NDB, the MySQL Cluster storage engine, is available in binary distributions for Linux, Mac OS X, Solaris. and Windows. We are working to support MySQL Cluster on all operating systems supported by the MySQL Server.
