前些天发现了一个巨牛的人工智能学习网站，通俗易懂，风趣幽默，忍不住分享一下给大家。点击跳转到教程。
1. 问题描述：阿里云服务器 磁盘初始化之后用 git-bash ssh root@xx.xx.xx.xx 方式登陆服务器，报错如下。
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ 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 isSHA256:V7h2Fdvk1Mc941+Bt6vJW8LpOGFDWVfFiQ3ezF/yzXo.Please contact your system administrator.Add correct host key in /c/Users/LYSM/.ssh/known_hosts to get rid of this message.Offending ECDSA key in /c/Users/LYSM/.ssh/known_hosts:7ECDSA host key for xxx.xx.xxx.xx has changed and you have requested strict checking.Host key verification failed.
2. 解决：清除之前连接过的信息记录。执行命令：
ssh-keygen -R XX.XX.XX.XX（这是服务器 IP）例如：ssh-keygen -R 172.168.2.59
3.重新 shh 登陆，一切正常。
