1.报错内容

1251 client does not support authentication protocol requested by server;consider upgrading Mysql client

ERROR 1396 (HY000): Operation ALTER USER failed for ‘root’@‘localhost’。

2.报错原因：由于mysql8以前的加密规则与mysql8以后的存在差异。

3.问题解决：

1.登录mysql

2.修改加密规则

ALTER USER  'root'@'localhost' IDENTIFIED BY 'password' PASSWORD EXPIRE NEVER;

3.更新用户密码

ALTER USER  'root'@'localhost' IDENTIFIED WITH mysql_native_password BY '1234';

4.刷新

 FLUSH PRIVILEGES;

sqlyog再次连接mysql，就可以连接成功。
