ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.

mysql初始化安装之后，执行语句报错：

ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement.

mysql需要修改初始密码，执行修改用户密码语句，

alter user 'root'@'localhost' identified by 'root';
