mysql8: client connection caching-sha2-password issue

Problem: caching-sha2-password

deal with:

    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 

Then reset the password: alter user 'root'@'localhost' identified by '123qwe';
