Install MySQL on Mac OSX using Homebrew
UPDATE: This post is probably very out of date. Please use at your own risk.
Recently, while doing some development on my Mac, I realized I didn’t have MySQL installed. I could have loaded up an instance of Ubuntu 12.04 LTS on VirtualBox and used that. However, I thought it would be much more convenient to have it available directly instead in a virtualized environment. Here are the instructions for installing it on a Mac using Homebrew.
This guide assumes Homebrew is installed and properly functioning.
First, ensure that Homebrew is update to date and ready to brew:
brew update brew doctor brew upgrade
Next, install MySQL:
brew install mysql
Start MySQL:
mysql.server restart
Secure your MySQL installation. The main purpose of doing this is to ensure that the configuration of the local environment is set up as close as possible to the production environment.

Run the following two commands to allow MySQL to run under your user account:
unset TMPDIR mysql_install_db --verbose --user=`whoami` \\ --basedir="$(brew --prefix mysql)" \\ --datadir=/usr/local/var/mysql --tmpdir=/tmp
Add the following my.cnf file to /etc:
# # The MySQL database server configuration file. # # You can copy this to one of: # - "/etc/mysql/my.cnf" to set global options, # - "~/.my.cnf" to set user-specific options. # # One can use all long options that the program supports. # Run program with --help to get a list of available options and with # --print-defaults to see which it would actually understand and use. # # For explanations see # http://dev.mysql.com/doc/mysql/en/server-system-variables.html # This will be passed to all mysql clients # It has been reported that passwords should be enclosed with # ticks/quotes escpecially if they contain "#" chars... # Remember to edit /etc/mysql/debian.cnf when changing # the socket location.

Restart the MySQL server:
mysql.server restart
