无论输入什么，都提示reset your password

re executing this statement.
mysql> CREATE DATABASE test;

re executing this statement.

解决方法-重置user密码（两个方法都可用）

方法一

set password=password("root");#表示设置密码为root

flush privileges;#更新权限

mysql> set password=password("root");
Query OK, 0 rows affected, 1 warning (0.35 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.23 sec)

方法二 

alter user user() identified by "123456"; #表示设置密码为123456

mysql> alter user user() identified by "123456";
Query OK, 0 rows affected (0.04 sec)

查看mysql的版本信息

mysql> select version()
    -> ;
+-----------+
| version() |
+-----------+
| 5.7.26    |
+-----------+
1 row in set (0.00 sec)

查看mysql密码生命周期

mysql> show variables like 'default_password_lifetime';
+---------------------------+-------+
| Variable_name             | Value |
+---------------------------+-------+
| default_password_lifetime | 0     |
+---------------------------+-------+
1 row in set, 1 warning (2.64 sec)
