在Ubuntu服务器上设置Rails时，Phusion Passenger出错

标签： ruby-on-rails ubuntu passenger

我需要帮助在Ubuntu 11.10服务器上运行rails应用程序。

我已经使用了大约2天，并且无法通过此处屏幕截图中显示的部分。据我所知，我有rvm，rails，ruby，capistrano，融合乘客都正确安装。我认为我的问题与数据库（mysql）有关，或者让轨道与数据库通信（我只是从下面的错误消息中猜测）。 

Error message:
undefined method `active_record' for #<Rails::Application::Configuration:0x00000002e43fe8>
Exception class:
NoMethodError
Application root:
/var/www/jamesbay/blog/current

我的主要问题是如何进行调试呢？ 我已经尝试修改config.ru文件，application.rb和environment.rb列出没有解决方案。我不完全确定这些错误甚至意味着什么！

我有capistrano正确部署到服务器上的目录。 我可以对git repo进行更新，并使用各种'cap'命令来处理从本地机器到服务器的实际部署。

任何帮助表示赞赏！ （我只使用rails大约2周，而且由于这个项目，我已经学会了关于服务器管理的TON）

切换到rails 1.9.3-p194（与我的dev机器相同）并删除p286后，当我转到我的网站时，我收到一条消息，说“你正在寻找的页面不存在”。

答案 0 :(得分：0)

我最终解决了我的问题。

主要问题是由于使用rvm安装和管理了多个版本的ruby。 这加上没有正确初始化我的数据库而没有正确设置我的apache路径导致错误。

我的默认ruby版本设置为ruby-1.9.3-p286，但我在我的开发机器上使用ruby-1.9.3-p194。我以前在服务器上安装了两个版本，但没有选择默认版本。确保在部署之前选择默认版本。

我正在使用子URI，而我没有使用符号链接正确设置路径。例如，我的应用程序文件位于/ home / username / appName中，公共目录位于/ home / username / appName / current / public。在我的DocumentRoot，/ var / www中，我创建了一个名为'appName'的符号链接，指向公共目录路径。我搞砸的地方是没有在/ etc / apache2 / sites-available / default文件中定义RackBasedURI路径。

此处引用此流程： http://www.modrails.com/documentation/Users%20guide%20Apache.html#deploying_rack_to_sub_uri
