使用scp在服务器之间传输文件，出现报错，这已经是第二次遇到这个问题了。 报错如下： @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!

出现错误的原因是：本地的known_hosts保存的主机hostkey记录改变了
执行以下代码可以解决问题
rm -rf ~/.ssh/known_hosts
注意：rm -rf命令一定要小心执行。 再使用scp命令传输文件，则没有问题啦。
