通過簡單的Rails應用程序使用瘦服務器時在日誌中出現意外錯誤

我在使用簡單的Rails應用程序上的瘦服務器方面很新穎。它的工作很好，除了，有一成的4倍以下，當我去到應用中的任何頁面我得到這個瀏覽器：通過簡單的Rails應用程序使用瘦服務器時在日誌中出現意外錯誤

Status: 500 Internal Server Error Content-Type: text/html 
Application error 

Change this error message for exceptions thrown outside of an action (like in Dispatcher   setups or broken Ruby code) in public/500.html

，這在日誌中：

更多解決方案的解決方法，但考慮使用會話的memcache存儲，這有利於更具可伸縮性，更快速並且有避免此問題的良機。順便說一下，你有分佈式架構，還是關於這個文件系統的特別之處？ – 2012-03-03 04:29:13

謝謝..但不，這是一個相當香草的設置。在Linode的Linux機器上運行Centos。只是嘗試通過Apache虛擬域啓動瘦服務器。任何其他想法？ – pitosalas 2012-03-03 13:29:41

對我來說，堅持的是rails-1.2.3在你的堆棧中。我相信如果你bundle exec thin你會得到正確版本的rails，但你也可以通過刪除所有不依賴於你的應用的gem來強制這個。雖然rvm非常適合開發，但我並不認爲它在系統級別安裝時帶來了很多價值，而且我聽到很多人在生產系統（尤其是CentOS）上掙扎着獲取環境正確無誤地運行用戶精簡。如果您不熟悉rails部署，請考慮使用像passenger這樣的東西，並且只需要依賴關係。
