【问题描述】：
我正在尝试使用 Rubber 将我的第一个应用程序部署到亚马逊 ec2。我已经尝试了好几次，每次都会出现 Mongo::Connection Failure 的过程错误。我已经尝试了来自多个层的几种不同的实例类型，但仍然遇到相同的错误。只是不知道如何进行。
这是错误日志：

【问题讨论】：
-
我对橡胶不熟悉；但是是否有应该运行的 mongodb 服务器进程？ “production.foo.com”看起来像一个虚假的服务器名称。
-
'production.foo.com' 基本上是一个错误的服务器名称。这就是我如何设置我的本地主机来查看我的网页。实际上，它不是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.. 比输入我的 ec2 实例 ip 更容易。我也是Rubber的新手。但似乎在引导步骤的某个阶段需要mongodb来在ec2上自动获取我的应用程序上的配置部分。我没有使用 mongodb 作为我的数据库，但无论出于何种原因，橡胶都使用它来引导我的应用程序到 ec2。
-
它显然是在尝试连接到名为 production.foo.com 的主机上的 mongodb 实例。显然橡胶依赖于mongodb？您可以尝试临时配置为使用“localhost”。
-
是的，橡胶似乎对 mongodb 有依赖。我对如何配置橡胶使用 localhost 有点茫然，因为我只是使用橡胶当前生成的默认设置。我会调查一下 - 感谢您的帮助。
