\[root@zk01 ~\]\# ssh localhost  
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@  
@ 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:r86jc/Vu8phhiKKDSntetfkmksjQ606ZlUP8XNYe44U.  
Please contact your system administrator.  
Add correct host key in /root/.ssh/known\_hosts to get rid of this message.  
Offending ECDSA key in /root/.ssh/known\_hosts:10  
Password authentication is disabled to avoid man-in-the-middle attacks.  
Keyboard-interactive authentication is disabled to avoid man-in-the-middle attacks.  
Permission denied (publickey,password,keyboard-interactive).

说明： Add correct host key in /root/.ssh/known\_hosts to get rid of this message.  重点在这句话

分析： ssh登录过某机器后，因某机器有变动（更换ip等），再次登录不了，报错！！！

解决过程：

\[root@zk01 ~\]\# mv /root/.ssh/known\_hosts /root/.ssh/known\_hosts.bak

\[root@zk01 ~\]\# ssh -o StrictHostKeyChecking=no 172.16.38.130  
Warning: Permanently added '172.16.38.130' (ECDSA) to the list of known hosts.  
root@172.16.38.130's password:  
Last login: Sun Oct 1 12:02:21 2017 from 172.16.74.104

\[root@zk01 ~\]\# ssh localhost      \#\# 输入密码，OK！  
Warning: Permanently added 'localhost' (ECDSA) to the list of known hosts.  
root@localhost's password:  
Last login: Sun Oct 1 12:04:59 2017 from zk01
