乗客+ Nginx => 502悪いゲートウェイ

比較的単純なRails app（http://www.enkiblog.com/））を実行しようとしていますが、それはちょっと機能します。コメントと管理インターフェースは、「スクリプト」を使用した場合にのみ機能します。/server -e production」を実行し、ポート3000に接続します（ただし、本番モードのままです）。

Nginxは彼のerror.logにこれを持っています：

それは乗客+ sqlite + nginx + unixパーミッションの問題であることが判明しました。
MySQLに移行して「解決」しました

SQLiteデータベースに適切な権限が設定されていない場合、nginxからこのような502エラーが発生する可能性があります。
