[root@rac1 ~]# scp installpackage.sh 192.168.8.237:/tmp/ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @    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.

因为同一个IP远端的信息有变动,与存在本地的公钥不相符.

解决办法:删除本地的记录信息1、[root@rac1 ~]# cd .ssh/            2、[root@rac1 .ssh]# ls known_hosts     3、 [root@rac1 .ssh]# vi known_hosts
