可能还是你的用户和密码的问题吧。在试一试我的办法。 先关闭mysql # service mysqld stop 把权限屏蔽 # mysqld_safe --skip-grant-table 会出现这样的字样: Starting demo from ..... 新开起一个终端输入 # mysql -u root mysql mysql> UPDATE user SET Password=PASSWORD('newpassword') where USER='root'; mysql> FLUSH PRIVILEGES;//记得要这句话,否则如果关闭先前的终端,又会出现原来的错误 mysql> \q 这样看看。
