mysql 错误:Client does not support authentication protocol requested by server

今天编程时，出现了一个如下错误：

 

mysql 错误:Client does not support authentication protocol requested by server， consider upgrading MySQL

 

客户端的认证协议与服务器不一致，需要更新客户端，网上找了一下解决办法

 

1：UPDATE mysql.user SET Password = OLD_PASSWORD('newpwd')
  WHERE Host = 'some_host' AND User = 'some_user';(生新设置密码)
2：FLUSH PRIVILEGES;（刷新）

 

新版Mysql密码算法不同导致
