This chapter describes how to obtain and install MySQL. You can choose to install MySQL Enterprise or MySQL Community Server:
MySQL Enterprise is Oracle Corporation's commercial offering for modern enterprise businesses. It includes MySQL Enterprise Server and the services provided by MySQL Network. To install MySQL Enterprise, see Section 2.3, “Notes for MySQL Enterprise Server”.
MySQL Community Server is for users who are comfortable configuring and administering MySQL by themselves. To install MySQL Community Server, see Section 2.4, “Notes for MySQL Community Server”.
If you plan to upgrade an existing version of MySQL to a newer version rather than install MySQL for the first time, see Section 2.19.1, “Upgrading MySQL”, for information about upgrade procedures and about issues that you should consider before upgrading.
If you are interested in migrating to MySQL from another database system, you may wish to read Section B.8, “MySQL 5.0 FAQ: Migration”, which contains answers to some common questions concerning migration issues.
