I spent much of 2009 writing the MySQL Admin Cookbook, together with my friend and colleague Udo Schwedt. Administrators of all skill-levels will find step-by-step in structions for practical approaches to MySQL configuration, maintenance, and optimization topics.
You can buy it from Amazon right here
Once you have ordered a copy (and only then ;-)) I very much invite you to find out a little about my experiences while writing it. I put them down in a series of posts on this blog. They are grouped under the mysql-admin-cookbook tag. Have fun!
