17.3.2.4. 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
NDB 7.3.0	string	[none]	...
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

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

This is the computer's hostname or IP address.
