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（这个路径在上面的报错中有体现，有注释标记） $ cd /Users/xxx/.ssh # 移除文件 $ sudo rm -rf known_hosts known_hosts.old # 然后再次执行报错的命令
