I want to make a cluster with two simple (INTEL SATA) pcs using CentOS, my question is? Is there something easiest than Linux RedHat Cluster Manager to make a cluster using CentOS with just two pcs? Regards, Israel

Heartbeat to create a small cluster in a active/passive (or even active/active for different services) configuration DRBD to replicate data automagically between nodes. Both are available in the extras repository .. -- Fabian Arrotin <fabian.arrotin at arrfab.net> -------------- next part -------------- A non-text attachment was scrubbed...

Israel Hello - just my school of hard nocks experience, and running several clusters - from the small 2 dual cpu boxes, to my largest of 64 dual cpu boxes. Try using the following - it uses CENTOS as the base. http://www.rocksclusters.org/wordpress/ It is free, works perfectly on anything that CENTOS can run on, fairly well documentated, and a good support system / network of users.

Apache, Mailscanner/Postfix, mysqld and squid are going to run in this cluster.. Regards, Israel

Web? Regards, Israel

(btw I believe, as far as projects "live" in any geographic location, openmosix lives in Israel). If you can hold out for RHEL5/CentOS5 then Xen might be useful. Apparently, and I've not done this, one can boot a Xen guest in one physical box, then migrate it to another while it's running. Google might be able to tell you about high availability (HA) linux. -- Cheers John -- spambait 1aaaaaaa at coco.merseine.nu Z1aaaaaaa at coco.merseine.nu Please do not reply off-list
