18.3.3.4 Defining Computers in a MySQL 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

  Effective Version	Type/Units	Default	Range/Values	Restart Type
  NDB 7.3.0	string	[none]	...	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

  Effective Version	Type/Units	Default	Range/Values	Restart Type
  NDB 7.3.0	name or IP address	[none]	...	N

  This is the computer's hostname or IP address.
