在使用MySQL时,出现了这样的错误提示:

you must reset your password using alter,让重设密码。

mysql 5.7增加了两个字段password_last_changed、password_lifetime来完善安全策略。
fault_password_lifetime来延长使用期限
或者

ALTER USER 'root'@localhost' PASSWORD EXPIRE INTERVAL 90 DAYS;
ALTER USER 'root'@'localhost' PASSWORD EXPIRE NEVER;
ALTER USER 'root'@'localhost' PASSWORD EXPIRE DEFAULT;

可以使用下面的语法进行权限设置:

mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY '518666' PASSWORD EXPIRE NEVER;
Query OK, 0 rows affected (0.00 sec)

设置成功之后,可以成功使用 use mysql命令了~
