很郁闷，为啥突然就不能用了。

网上说是得改root密码！

不过，还好我有一般用户，用一般用户可以登录，还可以用Navicat Preminu 看到其中的表

于是，我用一般用户连上数据库，打开mysql命令行，依次输入以下三个命令，就能顺利登录root了

SET PASSWORD FOR 'root'@'localhost' = PASSWORD('123456');

GRANT ALL PRIVILEGES ON *.* TO 'root' @'%' IDENTIFIED BY '123456' WITH GRANT OPTION;

flush privileges;

过程截图如下：

成功啦！
