因此，我在過去幾週一直在研究我的第一個（真正的）rails應用程序，昨天我試圖使用Rubber gem將它部署到Amazon EC2。在我部署我的實際項目之前，我對自己說：讓我們嘗試一個完全新鮮和簡單的項目上的橡膠，看看它是否工作。在執行這個[railscast] [1]中的步驟之後，所有的東西都可以在簡單的項目中使用。所以我試圖部署我的真實項目，執行與以前相同的步驟。橡皮執行了所有Capistrano腳本，一切看起來都很順利。但是，當我試圖訪問該網站時，出現此錯誤：503服務不可用使用橡膠部署Rails應用程序到EC2：503服務不可用
我使用了橡膠模板「complete_passenger_postgresql」。我成功部署的簡單項目與實際項目之間的橡膠設置基本相同。區別在於應用程序的實際內容。
查看日誌文件後，我就翻過這些錯誤：

Cou這是寶石「祖先」可能導致這個問題嗎？那麼「權限被拒絕」錯誤呢？
非常感謝您的幫助！
在您的Apache，Passenger和應用程序日誌中添加可能會讓我們更好地瞭解爲何發生這種情況。 – Veraticus
感謝Veraticus - 我只是更新了這篇文章。任何其他可能感興趣的日誌文件？我讀到Passenger錯誤日誌正被重定向到apaches錯誤日誌文件。 –
