WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! 翻译过来就是：警告：远程主机标识已更改！

此报错是由于远程的主机的公钥发生了变化导致的。ssh 服务是通过公钥和私钥来进行连接的，它会把每个曾经访问过计算机或服务器的公钥（public key），记录在 ~/.ssh/known_hosts 中，当下次访问曾经访问过的计算机或服务器时，ssh 就会核对公钥，如果和上次记录的不同，OpenSSH 会发出警告。

当两个设备第一次进行链接时，会在 ~/.ssh/konwn_hosts 中将被连接设备的公钥信息进行保存，后续再次链接时 OpenSSH 会核对公钥来进行一个简单的验证
【解决方法】找到报错中 known_hosts 的路径，进入该目录，删除掉 known_hosts、known_hosts.old 文件，然后重新执行之前报错的命令，应该会提示是否确定授权，输入 yes 就行了。

另外需要注意线上对应的公钥确实是你本机的 rsa 公钥。
```
# 进入目录
$ cd /Users/dengzemiao/.ssh

# 移除文件
$ sudo rm -rf known_hosts known_hosts.old

# 然后再次执行报错的命令
```
