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.

网上查了各种方法，都不太管用

解决方法:

1.主机生成密钥对 ssh-keygen  -t rsa

2.将主机上生成的公钥.pub复制到远程机器~/.ssh/authorized_keys (没有authorized_keys就新建一个，可以通过ssh-copy-id root@remote_ip -p 22复制)

3.修改/etc/ssh/sshd_config  ->  PunlicAuthentication yes; PasswordAuthentication yes

4.重启远程机器
