Therefore, here I’m using MySQL Cluster edition instead of MySQL Community edition. I’m using 3 servers (1 Management and 2 data) to setup cluster in CentOS 5.4 Linux box. The steps mentioned here can be used for quickly deploying a cluster and worked out for me but no guarantee that this will work for you, So its always advisable to go through official MySQL guide as well for production environment. In case you are also riding on cloud computing wave, I’ve already blogged way to setup MySQL cluster in Amazon EC2 environment.

In this case, after initial investigation, I’ve found that there are few ways to implement this. The idea of using MySQL Sandbox interested me most.
