这里就简单记录一下，因为网上写的仔细的比较少，我也写一份，希望病友们可以更方便的找到解决办法

其实就是mysql 之前的版本有问题导致的，只要卸载后重装就好了

卸载：

$ sudo rm -rf /usr/local/mysql*
$ sudo rm -rf /Library/StartupItems/MySQLCOM
$ sudo rm -rf /Library/PreferencePanes/MySQL*
$ rm -rf ~/Library/PreferencePanes/MySQL*
$ sudo rm -rf /Library/Receipts/mysql*
$ sudo rm -rf /Library/Receipts/MySQL*
$ sudo rm -rf /var/db/receipts/com.mysql.*

重装：

$ brew install mysql

mysql.server start
mkdir -p ~/Library/LaunchAgents 
ln -sfv /usr/local/opt/mysql/*.plist ~/Library/LaunchAgents 
find /usr/local/Cellar/mysql/ -name "homebrew.mxcl.mysql.plist" -exec cp {} ~/Library/LaunchAgents/ ; 
launchctl load -w ~/Library/LaunchAgents/homebrew.mxcl.mysql.plist
