16.4. MySQL Cluster Configuration
A MySQL server that is part of a MySQL Cluster differs in only one
respect from a normal (non-clustered) MySQL server, in that it
employs the NDB Cluster storage 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 NDB storage
engine disabled. To enable NDB, you must modify
the server's my.cnf configuration file, or
start the server with the --ndbcluster option.
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.cnf or on the MySQL server command line.
Before the NDB storage engine can be used, at
least one MGM node must be operational, as well as any desired
data nodes.
