If you want to make things a little simpler, an active/passive MySQL setup with pacemaker, corosync, and DRBD will work quite well. ClusterLabs has a pretty decent howto on their site: http://www.clusterlabs.org/wiki/DRBD_MySQL_HowTo As for RabbitMQ clustering, I worked with it for several days and had quite a few problems with data consistency and availability. We eventually settled on the "legacy" H/A method for RabbitMQ using pacemaker and DRBD. There's a pretty good walkthrough on RabbitMQ's site: http://www.rabbitmq.com/pacemaker.html -- Major Hayden _______________________________________________ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp
