注意点 1

必须先更改密码,而且密码是大小写字幕特殊符号数字四者都要有,然后才能再去修改密码等级…

注意点 2

MySQL版本8.0.21,在给新用户授权时,执行如下语句:

grant all privileges on *.* to 'root'@'%' identified by '123456' with grant option;

报错如下:

You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ‘identified by ‘password’ with grant option’

原因分析 :高版本的MySQL把将创建账户和赋予权限分开了。

解决方法:分开执行。

#创建账户
create user 'root'@'%' identified by '123456';

#赋予权限
grant all privileges on *.* to 'root'@'%' with grant option;

#刷新
flush privileges;
