Installing MySQL on Mac OS X

Installing MySQL on Mac OS X ,

You can install MySQL on Mac OS X 10.3.x (“Panther”) or newer using a Mac OS X binary package in PKG format instead of the binary tarball distribution. Please note that older versions of Mac OS X (for example, 10.1.x or 10.2.x) are not supported by this package.

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.

When installing from the package version, you should also install the MySQL Preference Pane, which will enable you to control the startup and execution of your MySQL server from System Preferences.

Due to a bug in the Mac OS X package installer, you may see this error message in the destination disk selection dialog:

You cannot install this software on this disk. (null)

If this error occurs, simply click the Go Back button once to return to the previous screen. Then click Continue to advance to the destination disk selection again, and you should be able to choose the destination disk correctly. We have reported this bug to Apple and it is investigating this problem.

The Mac OS X PKG of MySQL installs itself into /usr/local/mysql-VERSION and also installs a symbolic link, /usr/local/mysql, that points to the new location. If a directory named /usr/local/mysql exists, it is renamed to /usr/local/mysql.bak first. Additionally, the installer creates the grant tables in the mysql database by executing mysql_install_db.

The installation layout is similar to that of a tar file binary distribution; all MySQL binaries are located in the directory /usr/local/mysql/bin. The MySQL socket file is created as /tmp/mysql.sock by default. See Installation Layouts.

MySQL installation requires a Mac OS X user account named mysql. A user account with this name should exist by default on Mac OS X 10.2 and up.
