    $ ssh root@10.3.0.115
    @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
    @    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:CIxWlug9vwd2jdlatMmp1+xWXORX8oD8Kj6l9RKuosA.
    Please contact your system administrator.
    Add correct host key in /Users/zoe/.ssh/known_hosts to get rid of this message.
    Offending RSA key in /Users/zoe/.ssh/known_hosts:11
    ECDSA host key for 10.3.0.115 has changed and you have requested strict checking.
    Host key verification failed.
    

    known_hosts是记录远程主机的公钥的文件,之前重装个系统,而保存的公钥还是未重装系统的系统公钥,在ssh链接的时候首先会验证公钥,如果公钥不对,那么就会报错,

    解决办法:
    $ sudo vi ~/.ssh/known_hosts
    1、将known_hosts文件中的与登录错误的IP的公钥删除即可
    2、再次ssh登陆即可。
