getaddrinfo：solr sunspot 未知名称或服务

Question

我正在尝试使用 Rails 3.1 运行 solr 和 sunspot，但我不断收到错误消息，

getaddrinfo: Name or service not known

我的控制器相当基本

  def index
        @food_names = FoodName.search do 
            keywords(params[:term])
        end
  end

，我仍然不太确定这里发生了什么。我必须启动单独的 solr 服务吗？

当我运行 rake sunspot:solr:run 时，我得到了一个

有点令人不安的信息，但正如输出所示，服务器已经在运行，所以我认为它正在工作。

关于我可能做错了什么或者如何解决这个问题有什么建议吗？
