mysql8 ：客户端连接caching-sha2-password问题

报错：caching-sha2-password

先处理：

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

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

 FLUSH PRIVILEGES; #刷新权限 

再重置下密码：alter user 'root'@'localhost' identified by '123qwe';
