Configuration of MySQL Cluster NDB 7.3
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 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 [2296] option.
This MySQL server is a part of the cluster, so it also must know how to access an 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 [2296] and other mysqld options specific to MySQL
Cluster, see Section, “MySQL Server Options for MySQL Cluster”.
In MySQL Cluster NDB 7.3.1 and later, you can use the MySQL Cluster Auto-Installer to set up and
deploy a MySQL Cluster on one or more hosts using a browser-based GUI. For more information, see
Section 17.2.1, “The MySQL Cluster Auto-Installer”.
For general information about installing MySQL Cluster, see Section 17.2, “MySQL Cluster Installation”.
