我将mongrel集群和nginx模块安装到我的虚拟机上。 工作环境是
ruby 1.9.2 rails 3.0.6 rubygems 1.7.2 mongrel_cluster 1.0.5 mongrel 1.2 当我启动杂种群，它会抛出以下错误。 应用程序脱机请build议我一些解决scheme。 我已经尝试了很多使用Google的解决scheme，并没有解决这个问题。 任何forms的帮助表示赞赏。

编辑：
谢谢@dioms和@Hmallett。 我更新了gem，并从tmp / pids中删除了现有的pid文件，并重新启动了d群集。 它给了我错误

请给我build议一些解决办法。 我是服务器安装的新手，我不知道什么包括在configuration脚本。
看起来像你的一些gem已被弃用
试试这个来更新它们
gem update && gem update --system
tmp / pids / mongrel.8011.pid是否存在？
你确定杂种还没有在8011端口上运行吗？
如果是这样，rm tmp / pids / mogrel.8011.pid并尝试重新启动。
不赞成的gem警告只是一个警告，最后两行是线索为什么不启动。
另外，看起来你正在运行Ruby 1.9.1，但是我认为如果你想使用ruby 1.9，rails 3需要1.9.2。
