I I'm trying to do a cluster in my job, but I don't know which Distro to use, On internet I was read about the cluster distros, but no one offer to my a real support or least a serious mail list....

I have 4 nodes all Hp's Server, and a firewall configured whit Smooth Wall. My Cluster will be a net server and database server, may be a high performace cluster, somebody can help me?

Depends what kind of cluster you want. Load balancing? high performance? grid computing? job distribution? Failover?

Mhm. If you want to serve data on the "net" (Apache?) and want to run databases you propably want to use some Enterprise Linux distribution like SLES or RHEL (or their free alternatives without the commercial support).

Then I suppose you want to achieve a performance boost and high availability of your servers. Therefor you need some kind of HA manager like heartbeat or rgmanager.

For distributing the clients to your cluster nodes you could run a loadbalancer service on your cluster.

But you need to provide more details about what you really want to achieve.

thanks, really it's not a web server, it's a LAN domain server, in the cluster i want to manage the data of the office, the users, the e-mail and the internet connection.... I think could be a high performance or high avabaility cluster!

what you think?
