15.3.4.2. mysqld Command Options for MySQL Cluster

This section provides descriptions of mysqld server options relating to MySQL Cluster. For information about mysqld options not specific to MySQL Cluster, and for general information about the use of options with mysqld, see Section 5.1.2, “Server Command Options”.

For information about command-line options used with other MySQL Cluster processes (ndbd, ndb_mgmd, and ndb_mgm), see Section 15.4.21, “Options Common to MySQL Cluster Programs”. For information about command-line options used with NDB utility programs (such as ndb_desc, ndb_size.pl, and ndb_show_tables), see Section 15.4, “MySQL Cluster Programs”.

  • --ndb-connectstring=connect_string

    Command-Line Format --ndb-connectstring
    Config-File Format ndb-connectstring
      Permitted Values
    Type string

    When using the NDBCLUSTER storage engine, this option specifies the management server that distributes cluster configuration data. See Section 15.3.2.2, “The MySQL Cluster Connectstring”, for syntax.

  • --ndbcluster

    Command-Line Format --ndbcluster
    Config-File Format ndbcluster
    Option Sets Variable Yes, have_ndbcluster
    Disabled by skip-ndbcluster
      Permitted Values
    Type boolean
    Default FALSE

    The NDBCLUSTER storage engine is necessary for using MySQL Cluster. If a mysqld binary includes support for the NDBCLUSTER storage engine, the engine is disabled by default. Use the --ndbcluster option to enable it. Use --skip-ndbcluster to explicitly disable the engine.

  • --skip-ndbcluster

    Command-Line Format --skip-ndbcluster
    Config-File Format skip-ndbcluster

    Disable the NDBCLUSTER storage engine. This is the default for binaries that were built with NDBCLUSTER storage engine support; the server allocates memory and other resources for this storage engine only if the --ndbcluster option is given explicitly. See Section 15.3.1, “Quick Test Setup of MySQL Cluster”, for an example.
