使用 Passenger、Apache 和 Centos 时，子 URI 上的 Rails 权限错误

Question

我在运行 centos 6 的机器上安装了 rails 4 应用程序。我让 Apache 提供另一个应用程序，并尝试在子 uri 上安装 rails 应用程序。为了帮助部署，我安装了 Passenger。以下是我的主要 httpd 配置文件：

#CKAN
WSGISocketPrefix /var/run/wsgi

#RAILS Passenger
LoadModule passenger_module /usr/local/rvm/gems/ruby-2.1.2@ohana-api/gems/passenger-4.0.50/buildout/apache2/mod_passenger.so

<IfModule mod_passenger.c>
 PassengerRoot /usr/local/rvm/gems/ruby-2.1.2@ohana-api/gems/passenger-4.0.50
 PassengerDefaultRuby /usr/local/rvm/gems/ruby-2.1.2@ohana-api/wrappers/ruby
</IfModule>


<VirtualHost 0.0.0.0:80>
    ServerName xyz.clacksweb.org.uk
    ServerAlias xyz.clacksweb.org.uk
    WSGIScriptAlias / /etc/ckan/default/apache.wsgi

    # Pass authorization info on (needed for rest api).
    WSGIPassAuthorization On

    # Deploy as a daemon (avoids conflicts between CKAN instances).
    WSGIDaemonProcess ckan_default display-name=ckan_default processes=2 threads=15

    WSGIProcessGroup ckan_default

    ErrorLog /var/log/httpd/ckan_default.error.log
    CustomLog /var/log/httpd/ckan_default.custom.log combined


    #RAILS PASSENGER STUFF
    DocumentRoot /home/ohana/repos/ohana-api/public
    <Directory /home/ohana/repos/ohana-api/public/>
      Allow from all
      Options -MultiViews
      # Uncomment this if you're on Apache >= 2.4:
      # Require all granted
    </Directory>

    # These have been added:
    Alias /ohana /home/ohana/repos/ohana-api/public
    <Location /ohana>
      PassengerBaseURI /ohana
      PassengerAppRoot /home/ohana/repos/ohana-api
    </Location>

</VirtualHost>

当我访问 /ohana 子 uri 时，出现 403 禁止错误：“您无权访问此服务器上的 /ohana/。”

我尝试将应用程序的所有者和组从 ohana 用户切换为 root，然后再切换回来。我还应该检查什么？
