密码过期，需要重设密码，处理过程如下。

mysql> use mysql ERROR 1820 (HY000): You must reset your password using ALTER USER statement before executing this statement. mysql> set password = password('123456789'); Query OK, 0 rows affected, 1 warning (0.03 sec) mysql> flush privileges; Query OK, 0 rows affected (0.03 sec) mysql> exit Bye

重置密码后重新登录即可。
