22.3 Configuration of NDB Cluster
[+/-]
A MySQL server that is part of an NDB Cluster differs in one chief
respect from a normal (nonclustered) MySQL server, in that it
employs the NDB storage engine. This
engine is also referred to sometimes as
NDBCLUSTER, although
NDB is preferred.
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.
This MySQL server is a part of the cluster, so it also must know how
to access a management node to obtain the cluster configuration
data. The default behavior is to look for the management node on
localhost. However, should you need to specify
that its location is elsewhere, this can be done in
my.cnf, or with the mysql
client. Before the NDB storage engine
can be used, at least one management node must be operational, as
well as any desired data nodes.
For more information about
--ndbcluster and other
mysqld options specific to NDB Cluster, see
Section 22.3.3.9.1, “MySQL Server Options for NDB Cluster”.
You can use also the NDB Cluster Auto-Installer to set up and deploy an NDB Cluster on one or more hosts using a browser-based GUI. For more information, see The NDB Cluster Auto-Installer (NDB 7.5).
For general information about installing NDB Cluster, see Section 22.2, “NDB Cluster Installation”.
