使用Passenger部署Rails“您要查找的页面不存在”

Question

我正在尝试使用Passenger部署一个Rails应用程序。我遵循这个指南：http://wiki.ocssolutions.com/Deploying_a_Rails_Application_With_Passenger并安装了我所有的gem，但是当我转到我的应用程序应该在的位置时，我发现

The page you were looking for doesn't exist.
You may have mistyped the address or the page may have moved.

我知道这并不是很多的信息，但我不知道现在该怎么做。我从哪里开始解决这个问题呢？

编辑:这在日志中

一个可能的问题是，在开发时，我使用的是Ruby 1.9.3，而在生产环境中，服务器使用的是1.9.2。会不会是它造成的呢？

这是我的routes.rb文件：

Rideboard::Application.routes.draw do
  resources :requests

  get "info/about"

  resources :rides

  get "home/index"

  root :to => "rides#index"
end

Answer 1

实际上，您的routes.rb中没有与请求的路径/rideboard匹配的路由。但是，您似乎已经将您的应用程序本地部署到该子路径，因此http://your.host/rideboard实际上请求您的应用程序的根路径。

您可以尝试请求应用程序在服务器上的实际根路径，即http://your.server/。它可能会显示你的应用程序的主页。如果你真的想在/rideboard下部署它，你必须调整你的部署设置。对于passenger，您必须在遵循the documentation of Passenger的同时使用RackBaseURI。
