OSX Yosemite に MySQL5.5 をインストールする方法

デフォルトだと MySQL 5.6 が入るので、古い MySQL を入れる手順

brew uninstall mysql
brew tap homebrew/versions
brew install mysql55
ln -sfv /usr/local/opt/mysql55/homebrew.mxcl.mysql55.plist ~/Library/LaunchAgents
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.mysql55.plist
export PATH=$PATH:/usr/local/opt/mysql55/bin
mysql.server start

cp /usr/local/opt/mysql55/mysql-test/include/default_my.cnf /etc/my.cnf
