MySQL 8.0 Reference Manual Including MySQL NDB Cluster 8.0
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.
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, or mysqladmin shutdown on the command line.
To install MySQL using the package installer:
Download the disk image (.dmg
) file (the
community version is available
here) 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 8.0.40 it might be
named
mysql-8.0.40-macos-
.
10.13-x86_64
.pkg
The initial wizard introduction screen references the MySQL server version to install. Click
to begin the installation.The MySQL community edition shows a copy of the relevant GNU General Public License. Click
and then to continue.From the Installation Type page you can either click to execute the installation wizard using all defaults, click to alter which components to install (MySQL server, MySQL Test, Preference Pane, Launchd Support -- all but MySQL Test are enabled by default).
Although the
option is visible, the installation location cannot be changed.Click
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.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.
The default MySQL 8.0 password mechanism is
caching_sha2_password
(Strong), and this
step allows you to change it to
mysql_native_password
(Legacy).
Choosing the legacy password mechanism alters the generated
launchd file to set
--default_authentication_plugin=mysql_native_password
under ProgramArguments
. Choosing strong
password encryption does not set
--default_authentication_plugin
because the
default MySQL Server value is used, which is
caching_sha2_password
.
Define a password for the root user, and also toggle whether MySQL Server should start after the configuration step is complete.
Summary is the final step and references a successful and complete MySQL Server installation. the wizard.
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, see Section 2.4.3, “Installing and Using the MySQL Launch Daemon”, and Section 2.4.4, “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 file
mysql-8.0.40-
installs MySQL into
macos10.15-x86_64.dmg
/usr/local/mysql-8.0.40-macos10.15-x86_64/
with a symlink to
/usr/local/mysql
. The following table shows
the layout of this MySQL installation directory.
The macOS installation process does not create nor install a
sample my.cnf
MySQL configuration file.
