Setup Cluster doubts? (2 replies)

Hi.

I have been reading about cluster and want to try, but I have some doubts specifically what do I need to install on each machine?.

I will run this inside virtual machines with Xen on centos 5.5.

The doc say about data nodes, sql nodes, management server, management client.

I will use Centos for this to, but what software I have to install on:

sql node
data node
nmg_management

Is what I don't get it, because I have a lot software from redhat about clusters:

mysql-cluster-client
mysql-cluster-server
mysql-cluster-clusterj
mysql-cluster-management
mysql-cluster-shared
mysql-cluster-storage

etc, etc.

I don't fully understand which software goes on each part.

Any info about I will appreciated, thanks all for your time!!!
