當咱們使用ssh root@ip登陸Linux服務器時,服務器報錯:緩存
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ 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:Ms+BRn93GbOO1fwP6g1O+UwSRFv9KIUMGeoHDt70OfQ. Please contact your system administrator. Add correct host key in /Users/aliyunbaike/.ssh/known_hosts to get rid of this message. Offending ECDSA key in /Users/aliyunbaike/.ssh/known_hosts:6 ECDSA host key for 47.74.190.156 has changed and you have requested strict checking. Host key verification failed.
如何解決?緣由分析:服務器
這是因爲,ssh鏈接服務器時,若是以前鏈接過,ssh會默認保存該ip的鏈接協議信息,當咱們再次訪問此ip服務器時,ssh會自動匹配以前ssh保存的信息,因爲咱們的服務器作了更改,例如重裝系統等操做,會致使本地保存的ssh信息失效,因而再次鏈接時就會出現上述錯誤。ssh
另外,遠程服務器的ssh服務被卸載重裝或ssh相關數據(協議信息)被刪除也會致使這個錯誤。this
解決方案:spa
刪除本地known_hosts裏面的緩存信息便可。命令:ssh-keygen -R "你的遠程服務器ip地址" .net
注意:R是大寫!
