今天剛買了百度BCC，在那配置個(gè)Spring boot程序玩得甚歡。各種失誤后，準(zhǔn)備重裝系統(tǒng)，萬能大法好。
結(jié)果重裝后，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會(huì)把你每個(gè)你訪問過計(jì)算機(jī)的公鑰(public key)都記錄在~/.ssh/known_hosts。當(dāng)下次訪問相同計(jì)算機(jī)時(shí)，OpenSSH會(huì)核對(duì)公鑰。如果公鑰不同，OpenSSH會(huì)發(fā)出警告， 避免你受到DNS Hijack之類的攻擊。
原因：一臺(tái)主機(jī)上有多個(gè)Linux系統(tǒng)，會(huì)經(jīng)常切換，那么這些系統(tǒng)使用同一ip，登錄過一次后就會(huì)把ssh信息記錄在本地的~/.ssh/known_hsots文件中，切換該系統(tǒng)后再用ssh訪問這臺(tái)主機(jī)就會(huì)出現(xiàn)沖突警告，需要手動(dòng)刪除修改known_hsots里面的內(nèi)容。
Linux下
進(jìn)入自己本地電腦，刪除~/.ssh/konwn_hosts
Windows下
進(jìn)入自己本地電腦，刪除C:/Users/當(dāng)前user名字/.ssh/konwn_hosts
