Ssh
通過 SSH 連接 Amazon EC2 的權限被拒絕（公鑰）
當我嘗試通過 SSH 連接時。沒關係，但經過我的一些操作：-[ 我已經下載了密鑰對，複製到 .ec2，chmod 到 600，ssh-keygen -y -f ~/.ec2/gsg-keypair > ~/.ec2/gsg -keypair.pub 我正在使用 MacOS。我認為權限有問題……但我已經嘗試了所有組合和所有建議）

您需要修復您的 sshd 配置。您可以按照http://aws.amazon.com/instance-help/#no-response的“EBS-Backed Instances :: Instance Recovery”部分執行此操作。
第 4 步：“更正舊根卷上的配置。” 是您需要取消操作 sshd_config 的地方。
由於實例和卷操作非常緩慢，您應該通過使用配置在不同埠上啟動 sshd 來測試您的去模糊化 sshd_config 是否有效。確保實例的安全組允許連接到該埠。
