You must reset your password using ALTER USER statement before executing this statement

错误描述

  刚搭建完mysql的环境，使用初始化的默认密码登入后，输入任何命令都会提示如下：

MySQL [(none)]>use mysql;
ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.
MySQL [(none)]>show databases;
ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.

问题解决

  其实已经提示的很清楚了：在执行语句之前，必须要使用ALTER USER重置密码，那就重置呗。

MySQL [(none)]>alter user user() identified by '123456';
Query OK, 0 rows affected (0.00 sec)
MySQL [(none)]>show databases;
