mysql root密码过期

完成初始化的mysql数据库,没有及时登录修改密码导致默认密码过期,登录后提示:”Your password has expired.To log in you must change it using a client that supports expired passwords”

解决方法

1.停止服务并禁用授权登录

/etc/init.d/mysqld stop  ##关闭mysqld进程
vim /etc/my.cnf
[mysqld]
skip-grant-tables
:wq! #保存退出

2.进入mysql,查看root用户的详细信息

mysql -u root -p
> use mysql
> select * from mysql.user where user='root' \G

     password_lifetime: NULL
        account_locked: N
1 row in set (0.00 sec)

3、把password_expired 改成不过期

> update user set password_expired='N' where user='root';
> flush privileges;
> quit

4.把 /etc/my.cnf 的 skip-grant-tables 这行注释掉

5.重启服务

/etc/init.d/mysqld restart
