我对 Rails 和 Mac 还很陌生，正在做我的第一次部署......
我正在尝试在运行 OXS1.6 (Snow Leopard) 的全新 Apple 迷你服务器上设置我的 rails 应用程序。它目前在我的新 iMac i7（相同的操作系统）上运行良好。
我用这个命令开始杂种：
mongrel_rails start -e production -p 3000 -d -a 127.0.0.1 --debug
它开始在 log/mongrel.log 中给出这个输出
** Daemonized, any open files are closed. Look at log/mongrel.pid and log/mongrel.log for info.
** Starting Mongrel listening at 127.0.0.1:3000
** Installing debugging prefixed filters. Look in log/mongrel_debug for the files.
** Starting Rails with production environment...

** Writing PID file to log/mongrel.pid
我的开发 iMac 上的输出相同（包括警告）。
不同之处在于，http://127.0.0.1:3000在我的 iMac 上访问会提供应用程序的登录页面。在 mac mini-server 上访问相同的结果会导致来自 mongrel 的错误 500 文本：“我们很抱歉，但出了点问题。”
好像rails不起作用。如果我有一些日志文件消息可以指导我，我很擅长弄清楚事情，但是 mongrel.log 没有错误消息（输出与上面相同），并且 log/production.log 是空的（这使得我认为rails还没有开始？）。
我的宝石在机器之间都是相同的版本，应用程序代码也是如此；并且我在任何 mongrel_debug 日志中都看不到任何线索，除了 mac mini-server 和 iMac 上的 rails.log 不同。
在启动和单次访问之后，首先是来自 mac mini-server 的 rails.log：

在我的 iMac 上，除了添加了 HTTP_COOKIE 和 HTTP_IF_NONE_MATCH 之外，它看起来是一样的，这是我 iMac 的 rails.log
