Offending ECDSA key in /Users/bytedance/.ssh/known_hosts:6 Host key for 180.18x.193.xx has changed and you have requested strict checking. Host key verification failed.解决办法
在MAC terminal中打开如下文件，
vi . /Users/bytedance/.ssh/known_hosts
该路径是我的mac中的路径，在使用时需要把“bytedance”替换为你们的本机地址
删除文件中的所有内容，保存
重新用ssh密钥远程登录centos实例，成功解决
