MySQL 8.0 Reference Manual  /  ...  /  Defining Computers in an NDB Cluster

22.3.3.4 Defining Computers in an NDB Cluster

The [computer] section has no real significance other than serving as a way to avoid the need of defining host names for each node in the system. All parameters mentioned here are required.

  • Id

    Table 22.7 This table provides type and value information for the Id computer configuration parameter

    Property Value
    Version (or later) NDB 8.0.13
    Type or units string
    Default [none]
    Range ...
    Restart Type IS

    This is a unique identifier, used to refer to the host computer elsewhere in the configuration file.

    Important

    The computer ID is not the same as the node ID used for a management, API, or data node. Unlike the case with node IDs, you cannot use NodeId in place of Id in the [computer] section of the config.ini file.

  • HostName

    Table 22.8 This table provides type and value information for the HostName computer configuration parameter

    Property Value
    Version (or later) NDB 8.0.13
    Type or units name or IP address
    Default [none]
    Range ...
    Restart Type N

    This is the computer's hostname or IP address.
