我正在尝试使用Passenger和Apache运行我的rails应用程序。据我所知，我正确地遵循了这里的说明：http://www.modrails.com/documentation/Users%20guide%20Apache.html
当我的/ public目录中存在index.html文件时，url会为该页面提供服务。为了不使用我删除它的index.html文件，创建了一个新的控制器，在/app/views/home/index.html.erb下创建了一个新视图。在我的routes.rb文件中，我有：root :to => "home#index"
当我在过去完成此操作时，仅使用rails服务器中的内置版或使用瘦内容运行应用程序一直都很好，并且它为路由指向的erb文件提供服务。但是，在乘客的帮助下，只要我从公共场所删除index.html，我就会得到以下内容，而且我不确定如何修复它：

这就是我用Apache配置的：
<VirtualHost *:9090>
ServerName my.server.name:9090
DocumentRoot /var/www/app_dir/public
<Directory /var/www/app_dir/public>
AllowOverride all
Options -MultiViews
</Directory>
</VirtualHost>
