MySQL Replication

Published on Monday, January 23, 2006


The webapp server is running fine, but backups are important. Better yet, a hot computer is a great idea. To do this, I setup an older spare rackmount as a 'live' webapp server, just in case. A duplicate LAMP was setup, web apps copied over SSH via rsync on a regular basis, and the icing on the cake: mysql replication.

So, if the dedicated webapp server dies a painful death, a quick change of IP for the webapp server in the internal DNS to the backup rackmount, and nobody will know anything happened.
