SSH报错:Windows下删除known_hsots

今天刚买了百度BCC，在那配置个Spring boot程序玩得甚欢。各种失误后，准备重装系统，万能大法好。
结果重装后，SSH遇到Warning！

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.The fingerprint for the RSA key sent by the remote host is36:68:a6:e6:43:34:6b:82:d7:f4:df:1f:c2:e7:37:cc.Please contact your system administrator.Add correct host key in........

ssh会把你每个你访问过计算机的公钥(public key)都记录在~/.ssh/known_hosts。当下次访问相同计算机时，OpenSSH会核对公钥。如果公钥不同，OpenSSH会发出警告， 避免你受到DNS Hijack之类的攻击。

原因：一台主机上有多个Linux系统，会经常切换，那么这些系统使用同一ip，登录过一次后就会把ssh信息记录在本地的~/.ssh/known_hsots文件中，切换该系统后再用ssh访问这台主机就会出现冲突警告，需要手动删除修改known_hsots里面的内容。

Linux下

进入自己本地电脑，删除~/.ssh/konwn_hosts

Windows下

进入自己本地电脑，删除C:/Users/当前user名字/.ssh/konwn_hosts
