Question

我尝试使用scp将文件复制到远程服务器。

sudo scp atlassian-jira-6.4-x64.bin username@ip-adress:/

当我执行时，我收到错误：

WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!
    IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that a host key has just been changed.
The fingerprint for the RSA key sent by the remote host is
(fingerprint)
Please contact your system administrator.
Add correct host key in /var/root/.ssh/known_hosts to get rid of this message.
Offending RSA key in /var/root/.ssh/known_hosts:1
RSA host key for IPADRESS has changed and you have requested strict checking.
Host key verification failed.

所以我从〜/ .ssh中删除了known_hosts文件并再次尝试了该命令。但仍有这条消息出现。除了.ssh文件夹之外，我还需要在哪里修改我的文件？

Answer 1

使用终端上的known_host编辑器编辑以下目录下的vim文件。

 vi     /var/root/.ssh/known_hosts OR  /root/.ssh/known_hosts

使用dd命令删除所有行，并使用known_host保存:wq!文件并重新启动sshd服务。

service sshd restart

Answer 2

如果问题反复出现，您可以尝试使用此方法。

将以下行添加到SSH配置文件的开头。

Host *
   StrictHostKeyChecking no
   UserKnownHostsFile=/dev/null

或针对特定主机

Host localhost
        HostName localhost
        UserKnownHostsFile=/dev/null
        StrictHostKeyChecking=no

远程主机标识已更改
