Release Model and Versioning MySQL Cluster is developed and maintained at a different pace than the normal MySQL server. Having both separate allows to release more often and independently. With the new release model came a new versioning scheme. Here is an overview of MySQL Cluster versions with their full version: Download MySQL Cluster .. full version 6.3.33 mysql-5.1.44 ndb-6.3.33 7.0.14 mysql-5.1.44 ndb-7.0.14 7.1.2a mysql-5.1.41 ndb-7.1.2beta Just like the regular MySQL releases, MySQL Cluster can be downloaded from the Developer Zone on mysql.com: http://dev.mysql.com/downloads/cluster/. Here is an example of the tar-distribution for 32-bit Linux platforms, the one used in this tutorial: Installation mysql-cluster-gpl-7.1.2a-beta-linux-i686-glibc23.tar.gz You can install MySQL Cluster the same way you install a regular MySQL server. You are free to place it where ever you like, but the more ‘default’ on UNIX-like systems, is in /usr/local. Here are instructions for installing MySQL Cluster on a Linux 32-bit platform. shell> cd /usr/local shell> tar xzf mysql-cluster-gpl-7.0.13-linux-i686-glibc23.tar.gz shell> ln -s mysql-cluster-gpl-7.0.13-linux-i686-glibc23 mysql If you want more details, see the section ‘Installing MySQL from Generic Binaries on Unix/Linux’ in the MySQL Manual: http://dev.mysql.com/doc/refman/5.1/en/installing-binary.html Copyright © 2010, Oracle and/or its affiliates.
