Chapter 2 Installing MySQL on macOS Using Native Packages

The package is located inside a disk image (.dmg) file that you first need to mount by double-clicking its icon in the Finder. It should then mount the image and display its contents.

Note

Before proceeding with the installation, be sure to stop all running MySQL server instances by using either the MySQL Manager Application (on macOS Server), the preference pane, ormysqladmin shutdown on the command line.

To install MySQL using the package installer:

  1. Download the disk image (.dmg) file (the community version is availablehere) that contains the MySQL package installer. Double-click the file to mount the disk image and see its contents.

    Double-click the MySQL installer package from the disk. It is named according to the version of MySQL you have downloaded. For example, for MySQL server 8.0.44 it might be namedmysql-8.0.44-macos-10.13-x86_64.pkg.

  2. The initial wizard introduction screen references the MySQL server version to install. ClickContinue to begin the installation.

    The MySQL community edition shows a copy of the relevant GNU General Public License. ClickContinue and thenAgree to continue.

  3. From theInstallation Type page you can either clickInstall to execute the installation wizard using all defaults, clickCustomize to alter which components to install (MySQL server, MySQL Test, Preference Pane, Launchd Support -- all but MySQL Test are enabled by default).

    Note

    Although theChange Install Location option is visible, the installation location cannot be changed.

    Figure 2.1 MySQL Package Installer Wizard: Installation Type

    Content is described in the surrounding text.

    Figure 2.2 MySQL Package Installer Wizard: Customize

    Customize shows three package name options: MySQL Server, MySQL Test, Preference Pane, and Launchd Support. All three options are checked.

  4. ClickInstall to install MySQL Server. The installation process ends here if upgrading a current MySQL Server installation, otherwise follow the wizard's additional configuration steps for your new MySQL Server installation.

  5. After a successful new MySQL Server installation, complete the configuration steps by choosing the default encryption type for passwords, define the root password, and also enable (or disable) MySQL server at startup.

  6. The default MySQL 8.0 password mechanism iscaching_sha2_password (Strong), and this step allows you to change it tomysql_native_password (Legacy).

    Figure 2.3 MySQL Package Installer Wizard: Choose a Password Encryption Type

    Most content is described in the surrounding text. The installer refers to caching_sha2_password as "Use Strong Password Encryption" and mysql_native_password as a "Use Legacy Password Encryption".

    Choosing the legacy password mechanism alters the generated launchd file to set--default_authentication_plugin=mysql_native_password underProgramArguments. Choosing strong password encryption does not set--default_authentication_plugin because the default MySQL Server value is used, which iscaching_sha2_password.

  7. Define a password for the root user, and also toggle whether MySQL Server should start after the configuration step is complete.

    Content is described in the surrounding text.

  8. Summary is the final step and references a successful and complete MySQL Server installation.Close the wizard.

    Figure 2.5 MySQL Package Installer Wizard: Summary

    Shows that the installation was a success, and includes links to the MySQL manual, mysql.com, and oracle.com.

MySQL server is now installed. If you chose to not start MySQL, then use either launchctl from the command line or start MySQL by clicking "Start" using the MySQL preference pane. For additional information, seeChapter 3,Installing and Using the MySQL Launch Daemon, andChapter 4,Installing and Using the MySQL Preference Pane. Use the MySQL Preference Pane or launchd to configure MySQL to automatically start at bootup.

When installing using the package installer, the files are installed into a directory within/usr/local matching the name of the installation version and platform. For example, the installer filemysql-8.0.44-macos10.15-x86_64.dmg installs MySQL into/usr/local/mysql-8.0.44-macos10.15-x86_64/ with a symlink to/usr/local/mysql. The following table shows the layout of this MySQL installation directory.

Note

The macOS installation process does not create nor install a samplemy.cnf MySQL configuration file.
