会出现这些信息是因为，第一次SSH连接时，会生成一个认证，储存在客户端（也就是用SSH连线其他电脑的那个，自己操作的那个）中的known_hosts，但是如果服务器验证过了，认证资讯当然也会更改，服务器端与客户端不同时，就会跳出错误啦～因此，只要把电脑中的认证资讯删除，连线时重新生成，就一切完美啦～要删除很简单，只要在客户端输入一个指令
1 ssh-keygen -R +输入服务器的IP
接下来再次连接一次，会出现
Are you sure you want to continue connecting (yes/no)?
输入yes，
就完成连接啦！同時，新的认证也生成了
在mac下使用终端连接服务器方式
ssh root@服务器地址
