【问题描述】：

我一直在关注这个 railscast 教程，我很确定我正确地遵循了所有步骤，但是当我去运行 cap Rubber:create_staging 时，我得到了以下错误。

不知道从哪里开始调试。

 The key pair 'gsg-keypair' does not exist (Fog::Compute::AWS::NotFound)

【问题讨论】：

你能通过ssh -i path/to/privatekey root@ec2-xx...com ssh 进入你的实例吗？
hmm 不知道在哪里可以找到被 xx.com 替换的地址
这将是您的 ec2 实例的地址
这可能是我的问题我不认为我已经创建了一个 ec2 实例
如果您正在关注本教程railscasts.com/episodes/…，asciicast 会介绍如何获取 gsg 密钥并将它们放置在正确的目录中

【解决方案1】：

它说它找不到您的“gsg-keypair”，回到视频的部分，它教您如何从亚马逊保存 gsg-keypair 以及 mkdir 在根目录中保存的位置。

【解决方案2】：

您需要创建您的虚拟实例。然后下载密钥对（例如 xyz.pem）文件并按照这些命令进行操作。

$ mkdir ~/.ec2
$ mv ~/Downloads/xyz.pem ~/.ec2/xyz
$ chmod 600 ~/.ec2/xyz

制作公钥版本--

$ ssh-keygen -y -f ~/.ec2/xyz > ~/.ec2/xyz.pub

然后转到 config/rubber/rubber.yml 并将您的 key_name 更改为此

key_name: xyz
key_file: "#{Dir[(File.expand_path('~') rescue '/root') + '/.ec2/*' + cloud_providers.aws.key_name].first}"

希望这可以解决您的问题。
