I recently presented a webcast hosted by O’Reilly and Webex. In it I take you on a step-by-step installation of DRBD and MySQL. I start by using Sun’s Virtualbox to create to virtual machines running CentOS. I then explain how to configure them with virtual external drives to use for DRBD. I next configure the network interfaces to support routed packets into and out of the boxes. Then I install various packages with yum, configure drbd and finally install MySQL as the last step. You can follow along at the command line and do it yourself on a Windows, Mac or Linux box.
