17.3.2.7. MySQL Cluster TCP/IP Connections
TCP/IP is the default transport mechanism for all connections between nodes in a MySQL Cluster.
Normally it is not necessary to define TCP/IP connections; MySQL Cluster automatically sets up such
connections for all data nodes, management nodes, and SQL or API nodes.
To override the default connection parameters, it is necessary to define a connection using one
or more
[tcp]
connection between two MySQL Cluster nodes, and must contain at a minimum the parameters
and NodeId2, as well as any connection parameters to override.
NodeId1
It is also possible to change the default values for these parameters by setting them in the

To identify a connection between two nodes it is necessary to provide their node IDs in the
section of the configuration file. These are the same unique

MySQL Cluster Configuration Files
It is not necessary to perform any restart of the cluster if new SQL or API nodes
can employ previously unused API slots in the cluster configuration to connect
to the cluster.
