Question

我在服务器（Ubuntu 12.04 LTS）上安装了redmine 2.1，现在生成了500 Server错误消息。

我已配置为使用apache乘客并通过

安装

xxxx:/usr/local/vhost/redmine# ruby --version
ruby 1.8.7 (2011-06-30 patchlevel 352) [x86_64-linux]


gem --version
1.8.15


xxxxx:/usr/local/vhost/redmine/log# bundle --version
Bundler version 1.2.3


Started GET "/" for 217.247.62.52 at Sat Jan 05 13:39:34 +0000 2013
Processing by WelcomeController#index as HTML
Completed 500 Internal Server Error in 1ms

NoMethodError (undefined method `accept' for nil:NilClass):
  app/models/setting.rb:152:in `check_cache'
  app/controllers/application_controller.rb:82:in `user_setup'

我的database.yml适配器已经在mysql2上了：

production:
  adapter: mysql2
  database: redmine
  host: localhost
  username: root
  password: *****
  encoding: utf8

但这似乎是错误的，因为我使用的是ruby 1.8.7和不 1.9.X。

有人知道在哪里看吗？

更新重试后，我从网站上的passgen收到以下消息：

Answer 1

正如@khmarbaise所说，他的链接给了我解决方案：

在链接后面我们发现Passenger现在将rails - 应用程序视为rack - 应用程序，因此apache2-config是：

RailsBaseURI /redmine

现在应该是

RackBaseURI /redmine

这使我的工作（source）

Answer 2

部分是@Michael Witrant的答案，经过一段时间的搜索，我找到了以下link，这使我接受了正确的步骤。使用apache配置中的推荐条目更改后，我将配置从mysql2更改为database.yml文件中的mysql适配器，它可以正常工作。

Answer 3

您可能遇到与此问题相同的问题：Rails 3: Model.all => NoMethodError: undefined method 'accept' for nil:NilClass

尝试在mysql2中使用mysql适配器而不是database.yml。

Redmine安装不适用于apache乘客
