环境：本地机器mac 11.4、腾讯云CentOS 7.5 64位
因为装的minIO在根目录，文件结构有点乱，重装了下，通过终端连接的时候一直报错，如图：

网上找解决方案，没有直接解决，最后使用以下命令解决（带运行结果）：
caobodeMacBook-Pro:~caobo$ssh-keygen-R81.69.173.222#Host81.69.173.222found:line3/Users/caobo/.ssh/known_hostsupdated.Originalcontentsretainedas/Users/caobo/.ssh/known_hosts.old
最后再访问服务器效果：

问号那打yes回车就可以输密码了
