Linux同步文件报错：ECDSA host key for "ip地址" has changed and you have requested strict checking.

ECDSA host key for [172.83.153.115]:9527 has changed and you have requested strict checking.``

Linux SSH命令错误：ECDSA host key “ip地址” for has changed and you have requested strict checking.

原因：重装系统之后，SSH认证密钥失效。

解决办法 ：

1.需要清除你当前机器里关于你的远程服务器的缓存密钥信息，注意是大写的字母“R”。

ssh-keygen -R root@192.168.111.222
2.需要重新把服务器的id_rsa 文件拷贝到远程服务器/root/.ssh目录下，并命名authorized_keys 即

ssh-copy-id -i /root/.ssh/id_rsa.pub root@192.168.xxx.xxx
到此应该可以搞定了。
