MySQL™ Cluster Manager 1.4.8 User Manual


This is the User Manual for the MySQL™ Cluster Manager, version 1.4.8. It documents the MySQL Cluster Manager Agent and MySQL Cluster Manager Client software applications which can be used to administer MySQL NDB Cluster, a version of the MySQL Database System (referred to hereafter as MySQL Server or simply MySQL) that incorporates the NDB storage engine for high availability and data redundancy in a distributed computing environment.

This Manual applies to MySQL Cluster Manager 1.4.8 and contains information that may not apply to older versions of the MySQL Cluster Manager software. For documentation covering previous MySQL Cluster Manager releases, see MySQL Documentation: MySQL NDB Cluster, on the MySQL website.

MySQL Cluster Manager features.  This manual describes features that may not be included in every version of MySQL Cluster Manager, and such features may not be included in the version of MySQL Cluster Manager licensed to you. If you have any questions about the features included in your version of MySQL Cluster Manager, refer to your MySQL Cluster Manager license agreement or contact your Oracle sales representative.

MySQL Cluster Manager, MySQL Server, and MySQL NDB Cluster features.  This manual contains certain basic information about MySQL Server and MySQL NDB Cluster; however, it is not in any way intended as an exhaustive reference for either of these products.

Current versions of MySQL NDB Cluster compatible with MySQL Cluster Manager are based on versions 7.3, 7.4, 7.5, and 7.6 of the NDB storage engine; these versions of MySQL NDB Cluster are known as MySQL NDB Cluster 7.3, MySQL NDB Cluster 7.4, MySQL NDB Cluster 7.5, and MySQL NDB Cluster 7.6, respectively. MySQL NDB Cluster functionality varies between MySQL NDB Cluster releases; MySQL Cluster Manager cannot supply or emulate MySQL NDB Cluster features that are not present in the version of the MySQL NDB Cluster software in use.

For complete information about MySQL Server and MySQL NDB Cluster, please refer to the appropriate version of the MySQL Manual:


MySQL Cluster Manager 1.4.8 only supports MySQL NDB Cluster 8.0 on an experimental basis and should not be used with MySQL NDB Cluster 8.0 in a production environment. Also, here are some examples of MySQL 8.0 features that are not supported:

  • Any authentication plugins other than mysql_native_password when connecting with mcmd.
