This tutorial has notes on working with it, and how to install it securely. From the intro:
MySQL has become one of the most popular databases for Web applications. The database is well suited for common Web-related tasks like content management, and for implementing Web features like discussion boards and guestbooks. For a time, some developers avoided MySQL for commercial applications because it did not implement certain features, such as transactions. But this is no longer the case, and MySQL is a great choice for just about any Web-based application.
