国外VPS添加本地秘钥报错如何解决,目标重装服务器以后,本地添加密钥到这个服务器,发生如下报错:
[root@kvm_salt_zabbix gitlab]# ssh-copy-id -i /root/.ssh/id_rsa.pub root@47.52.x.x
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@ 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 the RSA host key has just been changed.
The fingerprint for the RSA key sent by the remote host is
de:af:f7:0e:b8:aa:87:a7:b7:79:c4:0a:59:fc:d2:46.
Please contact your system administrator.
Add correct host key in /root/.ssh/known_hosts to get rid of this message.
Offending key in /root/.ssh/known_hosts:1
RSA host key for 47.52.x.x has changed and you have requested strict checking.
Host key verification failed.
原因目标服务器重装以后,key发生变化。
解决办法1:
当前服务器(非目标服务器)vim ~/.ssh/known_hosts 删除这个目标服务器记录以后,重新添加即可。
解决办法2:
ssh-keygen -R 目标服务器IP 执行完命令以后重新添加。
