You should keep the following issues and notes in mind:
A launchd daemon is installed, and it includes MySQL configuration options. Consider editing it if needed, see the documentation below for additional information. Also, macOS 10.10 removed startup item support in favor of launchd daemons. The optional MySQL preference pane under macOS System Preferences uses the launchd daemon.
You may need (or want) to create a specific
mysqluser to own the MySQL directory and data. You can do this through the Directory Utility, and the
mysqluser should already exist. For use in single user mode, an entry for
_mysql(note the underscore prefix) should already exist within the system
Because the MySQL package installer installs the MySQL contents into a version and platform specific directory, you can use this to upgrade and migrate your database between versions. You will need to either copy the
datadirectory from the old version to the new version, or alternatively specify an alternative
datadirvalue to set location of the data directory. By default, the MySQL directories are installed under
alias mysql=/usr/local/mysql/bin/mysql alias mysqladmin=/usr/local/mysql/bin/mysqladmin
For tcsh, use:
alias mysql /usr/local/mysql/bin/mysql alias mysqladmin /usr/local/mysql/bin/mysqladmin
Even better, add
PATHenvironment variable. You can do this by modifying the appropriate startup file for your shell. For more information, see Section 4.2.1, “Invoking MySQL Programs”.
After you have copied over the MySQL database files from the previous installation and have successfully started the new server, you should consider removing the old installation files to save disk space. Additionally, you should also remove older versions of the Package Receipt directories located in
Prior to OS X 10.7, MySQL server was bundled with OS X Server.
