16.4.4. Configuration File
Configuring MySQL Cluster requires working with two files:
my.cnf: Specifies options for all MySQL
Cluster executables. This file, with which you should be
familiar with from previous work with MySQL, must be
accessible by each executable running in the cluster.
config.ini: This file is read only by
the MySQL Cluster management server, which then distributes
the information contained therein to all processes
participating in the cluster.
config.ini contains a description of
each node involved in the cluster. This includes
configuration parameters for data nodes and configuration
parameters for connections between all nodes in the cluster.
We are continuously making improvements in Cluster configuration
and attempting to simplify this process. Although we strive to
maintain backward compatibility, there may be times when
introduce an incompatible change. In such cases we will try to
let Cluster users know in advance if a change is not backward
compatible. If you find such a change and we have not documented
it, please report it in the MySQL bugs database using the
instructions given in Section 1.8, “How to Report Bugs or Problems”.
