Ruby on rails Mongo:：在create_登台期间将Rails应用程序部署到EC2时连接失败

我正在尝试使用Rubber将我的第一个应用程序部署到AmazonEC2。我已经尝试了好几次，每次进程都会因为Mongo:：Connection Failure而出错。我已经尝试了多个层中的几种不同实例类型，但仍然得到相同的错误。只是不知道如何进行

以下是错误日志：

我遇到了完全相同的问题，老实说，我只是再次运行了“cap rubber:bootstrap”，出于某种原因，它解决了问题…

我不熟悉橡胶；但是是否有应该运行的mongodb服务器进程？”production.foo.com看起来像一个伪造的服务器名。production.foo.com基本上是一个bugus服务器名。这只是我如何设置本地主机来查看我的网页。它实际上不是一个其他人可以连接的网址，但我可以在本地机器上使用它来查看我部署的应用程序。。比键入我的ec2实例ip更容易。我对橡胶也不熟悉。。但在引导步骤的某个阶段，似乎需要mongodb在ec2上自动获取应用程序上的配置部件。我没有使用mongodb作为我的数据库，但出于任何原因，rubber正在使用它将我的应用程序引导到ec2。它显然是在尝试连接到名为production.foo.com的主机上的mongodb实例。显然橡胶依赖mongodb？您可以尝试临时配置为使用“localhost”。是的，rubber似乎对mongodb有依赖性。我对如何配置rubber以使用localhost有点不知所措，因为我只是使用rubber当前生成的默认设置。我会调查的，谢谢你的帮助。
