尝试按照railscast教程部署到亚马逊ec2

Question

我一直在遵循这个铁路广播教程，我非常确定我正确地遵循了所有的步骤，但当我运行cap rubber:create_staging时，我得到了以下错误。

甚至不确定从哪里开始调试它。

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

Answer 1

它说它找不到你的' gsg-keypair '，回到视频的部分，它教你如何保存来自amazon的gsg-keypair，以及在你的根目录中mkdir在哪里保存。

Answer 2

您需要创建虚拟实例。然后下载密钥对(例如xyz.pem)文件并执行以下命令。

$ 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

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

希望这能解决你的问题。
