This chapter describes how to obtain and install MySQL. A summary of the procedure follows and later sections provide the details. If you plan to upgrade an existing version of MySQL to a newer version rather than install MySQL for the first time, see Section 2.11, “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, see Section A.8, “MySQL 8.0 FAQ: Migration” , which contains answers to some common questions concerning migration issues. 

Installation of MySQL generally follows the steps outlined here: 

## 1. Determine whether MySQL runs and is supported on your platform. 

Please note that not all platforms are equally suitable for running MySQL, and that not all platforms on which MySQL is known to run are officially supported by Oracle Corporation. For information about those platforms that are officially supported, see https://www.mysql.com/support/supportedplatforms/ database.html on the MySQL website. 

## 2. Choose which distribution to install. 

Several versions of MySQL are available, and most are available in several distribution formats. You can choose from pre-packaged distributions containing binary (precompiled) programs or source code. When in doubt, use a binary distribution. Oracle also provides access to the MySQL source code for those who want to see recent developments and test new code. To determine which version and type of distribution you should use, see Section 2.1.2, “Which MySQL Version and Distribution to Install” . 

## 3. Download the distribution that you want to install. 

For instructions, see Section 2.1.3, “How to Get MySQL” . To verify the integrity of the distribution, use the instructions in Section 2.1.4, “Verifying Package Integrity Using MD5 Checksums or GnuPG” .
