如题,最近双11买了阿里云服务器,然后倒腾。

由于一系列我自己的无法理解的操作之后,恐将服务器搞坏,打算重置服务器。于是,进行了如下操作:

选中自己要重置的阿里云服务实例-》停止实例-》更多=》磁盘和镜像-》重新初始化磁盘

一波操作之后,重新启动服务器,然后准备右键新建远程连接。开开心心准备通过ssh远程链接服务器。结果发现报错如下:

@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ 
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 ECDSA key sent by the remote host 
is SHA256:M3gbfQPCs8Y/y07otgS5BtZM9kSrCGYznCdatU2XF2g. 
Please contact your system administrator. Add correct host key in 
/Users/zhangyanling/.ssh/known_hosts to get rid of this message. 
Offending ECDSA key in /Users/zhangyanling/.ssh/known_hosts:2 
ECDSA host key for 47.110.54.75 has changed and you have 
requested strict checking. Host key verification failed.

大概猜了一下原因,远程host定义已经被更改。还是一脸懵逼啊,不说了,赶紧复制错误信息搜索一波。得到解决办法如下:

ssh-keygen -R <host>
比如,

ssh-keygen -R 192.168.3.10

然后就搞定了!
