mysql忘记密码解决办法

Posted 2021-01-12 Qiao_Zhi

　　今天，在新装的mysql上限制只能通过127.0.0.1登录之后怎么也登录不上。

1.在my.cnf最后一行(或者mysqld下面)设置跳过密码验证的过程（windows是my.ini）

skip-grant-tables

 

 

2.重启mysql服务

service mysqld restart

 

 

3.直接输入mysql即可

[[email protected]_0_12_centos ~]# mysql
Welcome to the MySQL monitor.  Commands end with ; or g.
Your MySQL connection id is 1313
Server version: 5.6.41 MySQL Community Server (GPL)

Type ‘help;‘ or ‘h‘ for help. Type ‘c‘ to clear the current input statement.

 

 

4.修改密码:

update user set Password=PASSWORD("newword") where user=‘root‘;

 

 

5.使修改生效

flush privileges;

 

 

6.修改完之后记得去掉跳过密码验证的设置，修改/etc/my.cnf去掉设置

 

7.正常使用即可
