Great guide, i am currently looking into configuring a cluster under linux (since windows i only in beta) and this guide is so clear, i am sure i will be visiting it often!

“Currently I’m testing that thing and will blog the stuff here very soon, till then stay tuned.”

Cant wait, will be doing this in 3 vm’s first for testing.

@Phrontiste
Hi phrontiste,

I preferred combining data nodes+sql nodes in both servers, so you can access mysql from any of them. I tested my cluster and it gave good results.

on other side for your info, for my environment, though I tested MySQl cluster but at the end, decided on implementing Master-Master replication setup because MySQL cluster have some distinct characteristics which your app might not like. more details can be found on MySQL site docs.

Hi Jagpir,

Thank you so MUCH !!!!!!

I read a sun.com article / pdf, in which it states that data nodes are separate as compared to the MySQL Server ?

Do you think one would be good in a high traffic environment with One Management and 2 data nodes ? or do we need the MySQL Server installed on two servers and then they talk to the data nodes ?
Sorry for being dump, I will post my findings / results to you.

my email is phrontiste @ gmail dot com

Thanks again
