我試圖使用SSH訪問EC2上的新Ubuntu實例。我注意到很多人都遇到了同樣的問題,並使用了不同的解決方法,但迄今爲止還沒有能夠實現這一目標。對AWS EC2的SSH訪問權限 - 拒絕權限

任何幫助將不勝感激。

一旦我有類似的問題。我無法解決它,但我解決了它。你可以做的是從你嘗試訪問的機器的EBS中創建一個AMI,然後從這個AMI中啓動一個新的實例並指定創建一個新的密鑰對。然後,AWS應該將您的新私鑰添加到allowed_keys中,並讓您進入新機器。那時你可以擊落舊的。

希望這會有所幫助。

因爲你是從服務器獲取Permission denied (publickey)消息存在連接任何問題。 確保與TBKEY1.pem相關的密鑰對與您的實例相關聯。如果它被鏈接,那麼它應該顯示爲下面的截圖。
