win10系统更新安装Mysql8.0,连接SQLyog的时候出现下面错误
1.打开cmd:mysql -u root -p
输入密码root
2.进入mysql依次执行下面语句
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';
再连接就没有问题了
