Windows安装Mysql8.0,连接SQLyog的时候出现下面错误

解决办法：

1. 打开CMD：mysql -u root -p

输入密码

2. 进入mysql后

ALTER USER'root'@'localhost' IDENTIFIED BY 'root' PASSWORD EXPIRE NEVER;#修改加密规则

ALTER USER'root'@'localhost' IDENTIFIED WITH mysql_native_password BY 'root'; #更新一下用户的密码

FLUSH PRIVILEGES; #刷新权限

重置密码：alter user'root'@'localhost' identified by 'root';

重启SQLyog就好了
