安装mysql8.11后，客户端连接报caching_sha2_password错误

         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';
