問題を再現する手順は何ですか?

  1. パッセンジャー 4.0.23 を使用して、ゴムを使用して amazon ec2 にレールをセットアップします。
  2. 配備
  3. Apache ログを確認する

期待される出力は何ですか？代わりに何が表示されますか?

RailsのWebサイトが機能することを期待しています。ページを表示できません。

Phusion Passenger、Rails、OSのバージョン

Rails 4.0.0 Passenger 4.0.23 OS Amazon EC2 上の Ubuntu 12.04

以下の追加情報。

ruby gem を使用して amazon ec2 インスタンスをセットアップしました。すべてがうまくいきました。そして、デプロイは成功しました。しかし、アプリをライブで見ることができませんでした。Apache のログを確認したところ、パッセンジャー エラーがありました。

アップデート

Hongli のアドバイスに従い、MaxPoolSize を 5 に減らしました。

今、私はこれをエラーログに記録します。

これは、サーバーのセットアップが成功したことを意味すると思います。しかし、それでも自分のサイトをオンラインで閲覧することはできません。（私はすでにセキュリティグループをチェックしました.0.0.0.0からポート80/443を許可しています.mysqlでも同じです.Rails/log/production.logは空です.

Phusion Passenger の著者はこちら。

ログでこれに気づきましたか?

 Cannot allocate memory - fork(2) (Errno::ENOMEM)

これは、システムのメモリが不足していることを意味します。

そして、これに気づきますか？

 An error occurred while starting the web application.
 It exited before signalling successful startup back to Phusion Passenger.

これは、Passenger が Web アプリのプロセスを生成しようとしたが、前述のエラー (メモリ不足) のために失敗したことを意味します。

できることは 3 つあります。

  • メモリをアップグレードします。
  • スワップスペースをアップグレードします。
  • Passenger の設定を微調整して、多くのプロセスが開始されないようにします。これにより、メモリを節約できます。オプションの微調整については、パッセンジャーのマニュアルを参照してください。
