猜测是和最近添加了

但是不对啊。应该自动判断host的IP不同，不实用本地的私钥的啊

然后再去执行rsync调用ssh去上传文件，就可以了。
【总结】
此处rsync第一次调用ssh去上传同步文件到远程服务器，会报错：
Host key verification failed
原因：
好像是没有去ssh验证过，rsync无法识别？
总之，解决办法是：
命令行中去：
ssh -v [email protected]
然后对于：
Are you sure you want to continue connecting (yes/no)?
输入yes，会提示：
Warning: Permanently added ‘42.123.123.254’ (ECDSA) to the list of known hosts.
-》估计内部就是保存了密钥等信息，通过了服务器的ssh验证，本地保存了验证信息。
->接着输入密码，即可登录远程服务器。
->之后再去rsync调用ssh，就可以了。
