Oracle distributes a series of 12 RPM packages that make up the MySQL Cluster product. Lately I've been getting a lot of questions asking which of these dozen RPM packages should be installed onto which nodes.

An overview of the contents of each RPM package is provided in the documentation at http://dev.mysql.com/doc/refman/5.1/en/linux-rpm.html and http://dev.mysql.com/doc/refman/5.1/en/mysql-cluster-multi-install.html. I think this section of the documentation is a bit messy so I'll give a short description of each here:

MySQL-Cluster-gpl-client
This package contains the standard MySQL clients and administration tools.
Contains: mysql, mysqladmin, mysqlcheck, mysqldump, etc...
This package should be installed …
