17.4. MySQL Cluster Programs

Using and managing a MySQL Cluster requires several specialized programs, which we describe in this chapter. We discuss the purposes of these programs in a MySQL Cluster, how to use the programs, and what startup options are available for each of them.

These programs include the MySQL Cluster data, management, and SQL node processes (ndbd, ndbmtd, ndb_mgmd, and mysqld) and the management client (ndb_mgm).

Information about the program ndb_setup.py (added in MySQL Cluster NDB 7.3.1), used to start the MySQL Cluster Auto-Installer, is also included in this section. You should be aware that Section 17.4.21, "ndb_setup.py — Start browser-based Auto-Installer for MySQL Cluster", contains information about the command-line client only; for information about using the GUI installer spawned by this program to configure and deploy a MySQL Cluster, see Section 17.2.1, "The MySQL Cluster Auto-Installer".

For information about using mysqld as a MySQL Cluster process, see Section 17.5.4, "MySQL Server Usage for MySQL Cluster".

Other NDB utility, diagnostic, and example programs are included with the MySQL Cluster distribution. These include ndb_restore, ndb_show_tables, and ndb_config. These programs are also covered in this section.

The final portion of this section contains tables of options that are common to all the various MySQL Cluster programs.
