我在虚拟机上安装了mongrel集群和nginx模块。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 mongrel 集群时，它抛出了以下错误。应用程序处于离线状态。请给我一些解决方案。我尝试了很多谷歌解决方案，但没有一个能解决这个问题。任何帮助我都会很感激。

编辑：
谢谢@dioms和@Hmallett。我更新了gems并从tmp/pids中删除了已经存在的pid文件，然后重新启动了d集群。它给了我d错误

请给我一些解决方案。我是服务器安装的新手，我不确定在配置脚本中到底要包含什么。
答案1
看起来你的一些宝石已被弃用
尝试这个来更新它们
gem update && gem update --system
答案2
tmp/pids/mongrel.8011.pid 存在吗？
您确定杂种尚未运行并监听端口 8011 吗？
如果是这样，请 rm tmp/pids/mogrel.8011.pid 并尝试重新启动。
弃用的 gem 警告只是一个警告，最后两行是它无法启动的线索。
另外，看起来您正在运行 Ruby 1.9.1，但我认为如果您想使用 ruby 1.9，rails 3 需要 1.9.2。
