sudo rm /usr/local/mysqlsudo rm -rf /usr/local/mysql*sudo rm -rf /Library/StartupItems/MySQLCOMsudo 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。
