Configuring the data nodes and SQL nodes.
simple. The configuration file should be located in the
editor. (Create the file if it does not exist.) For example:
shell> vi /etc/my.cnf

We show

For each data node and SQL node in our example setup,
[mysqld]
# Options for mysqld process:
ndbcluster
[mysql_cluster]
# Options for MySQL Cluster processes:
ndb-connectstring=192.168.0.10
After entering the preceding information, save this file and exit the text editor. Do this for the machines
hosting data node "A", data node "B", and the SQL node.

DataMemory=80M # How much memory to allocate for data storage
IndexMemory=18M # How much memory to allocate for index storage
# For DataMemory and IndexMemory, we have used the
# default values. Since the "world" database takes up
# only about 500KB, this should be more than enough for
# this example Cluster setup.
