今天在209服务器上要远程登录另外一台54的服务器，结果用ssh连接提示如下错误：
[root@NHL ~]# ssh root@10.40.49.54 @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!

在网上找资料，原来这是Linux重装或者openssh-server重装引起的，执行以下命令即可
ssh-keygen -R 10.40.49.54
10.40.49.54换成你要连的服务器就可以了。

我才想起来前几天我在54那台服务器上升级过ssh
