Hi, I have been using ipvs (keepalived) to provide high-availability for mysql service. I have this setup:
1 mysql replication and lvs director master. 1 mysql slave and lvs director backup. This means that both my servers acts as directors and at the same time, real servers. A master who becomes a backup would be permanently be in such state when revived and the fomer slave actively becomes the master until another failure. LVS director state switching is handled by keepalived, while bash scripts called within the keepalived configuration file (notify_master/notify_backup) would make the transition from one state to another. In short, whilst providing high-availabity thru lvs(keepalived), I also am doing mysql replication setup riding with every lvs+director transition, this is so because of I would have to turn over the system to an admin who isn't very much well versed with Linux. Is this a good setup up? I'm a bit paranoid about some data lose. _______________________________________________ LinuxVirtualServer.org mailing list - [email protected] Send requests to [EMAIL PROTECTED] or go to http://lists.graemef.net/mailman/listinfo/lvs-users
