CentOS has been distributing the Enterprise version of MySQL as part of our CentOS Web Stack that is in the CentOSPlus repository of CentOS-4 for quite a while.

http://wiki.centos.org/Repositories/CentOSPlus/CentOSWebStack

MySQL has recently changed it's policy concerning the distribution of it's Enterprise Sources (they no longer distribute them as a tarball):

CentOS has also had problems getting Red Hat to distribute their GPL'ed SRPM to us for the Enterprise MySQL version of their Red Hat Web Application Stack (due to an agreement between MySQL and Red Hat):

https://bugzilla.redhat.com/show_bug.cgi?id=230412

However, as you have come to expect from the CentOS project ... we did not take these answers to mean that we would not be able to get the Enterprise Sources for MySQL and distribute enterprise grade RPMS to our customers.

I would like to publicly thank Proven Scaling, LLC http://www.provenscaling.com/ (and specifically Jeremy Cole) for continuing to provide the GPL'ed tarball in question. Because of their efforts and because of the organization that they contribute to known as Dorsal Source http://www.dorsalsource.org/ we will continue to be be able to easily provide the CentOS community with updated enterprise RPMS for MySQL. I would also like to personally recommend Proven Scaling, LLC for any and all MySQL related work that you might need to have accomplished, they are good people :D

That said, the latest version of MySQL that we are building for the CentOS Web Stack has a package called mysql-cluster. It was added upstream in version 5.0.40 of the upstream product and this (mysql-cluster-5.0.48-1.el4.centos.i386.rpm and mysql-cluster-5.0.48-1.el4.centos.x86_64.rpm) is it's first appearance in the CentOS Web Stack.

The mysql-cluster files are produced by adding this switch to the compile mysql configuration statement:

--with-ndbcluster

For information about how you would use mysql-cluster, please see this mysql documentation:

http://dev.mysql.com/doc/refman/5.0/en/mysql-cluster.html

This new mysql-cluster package is not required for normal mysql operations, and will be available also for CentOS-5 from the testing repository soon.

NOTE: for anyone who wants to upgrade their MySQL in CentOS-4, you need to follow this guide if moving from the standard CentOS-4 (mysql-4.1.x) to the CentOS webstack (mysql-5.0.x):
