MySQL 5.7 Reference Manual  /  MySQL NDB Cluster 7.5  /  Configuration of NDB Cluster

19.3 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 19.3.3.8.1, “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 Section 19.2.1, “The NDB Cluster Auto-Installer”.

For general information about installing NDB Cluster , see Section 19.2, “NDB Cluster Installation”.
