嘗試將SSH登錄到EC2實例 - 權限被拒絕

通過SSH第一次登錄到EC2。它無法打開私鑰文件。所以我將chmod改爲700，但仍然拋出相同的錯誤。請建議我如何解決它。嘗試將SSH登錄到EC2實例 - 權限被拒絕

只是想出瞭如何解決它。因爲它是訪問問題，我把sudo放在前面，這一切都很好。 – user1146904

從您的EC2實例下載的文件位於哪裏？

你可以用.pem在目錄上做一個ls -la，這樣我們可以看到誰擁有.pem文件？

你還設置了EC2實例上的任何安全措施，例如192.168.0.0/24可以訪問此實例的端口22/tcp？

您有權限拒絕嘗試打開密鑰文件的錯誤。

我會做一個ls -la，看看你的用戶實際擁有的文件，並且它被設置爲權限0700

如果它不是由你的用戶所擁有的，你需要：

whoami # this will tell you your user's name 
chown user aug1981.pem
