mysql 1045(28000)问题处理(skip-grant-tables修改my.ini失效):

1)打开命令提示符,关闭MySQL服务:net stop mysql

2)输入 :mysqld --console --skip-grant-tables --shared-memory

3)保持当前窗口,另开新的cmd窗口,输入mysql,跳过密码登录,进入mysql

4)修改密码 ,转载自https://blog.csdn.net/wolf131721/article/details/93004013

MySql 从8.0开始修改密码有了变化,在user表加了字段authentication_string,修改密码前先检查authentication_string是否为空

①如果不为空

use mysql;

update user set authentication_string='' where user='root';--将字段置为空

ALTER user 'root'@'localhost' IDENTIFIED BY 'root';--修改密码为root

②如果为空

ALTER user 'root'@'localhost' IDENTIFIED BY 'root';--修改密码为root

注意:

如果出现如下错误

ERROR 1290 (HY000): The MySQL server is running with the --skip-grant-tables option so it cannot execute this statement

mysql> GRANT ALL PRIVILEGES ON *.* TO IDENTIFIED BY '123' WITH GRANT OPTION

需要执行

flush privileges;

然后再执行

ALTER user 'root'@'localhost' IDENTIFIED BY 'root';--修改密码为root
