卸载mysql

先停止所有mysql有关进程。 打开控制台:依次输入以下命令

sudo rm /usr/local/mysql

sudo rm -rf /usr/local/mysql*

sudo rm -rf /Library/StartupItems/MySQLCOM

sudo rm -rf /Library/PreferencePanes/My*

vim /etc/hostconfig and removed the line MYSQLCOM=-YES-rm -rf ~/Library/PreferencePanes/My*

sudo rm -rf /Library/Receipts/mysql*

sudo rm -rf /Library/Receipts/MySQL*

sudo rm -rf /var/db/receipts/com.mysql.* 最后这条很多文章都丢了，切记切记。
