Ulimitおよびmake_sockエラー

この方法を使用して、Ubuntu 11.10用のRedmineを構成しようとしています Redmine for 11.1 ですが、Apacheのどこかで異常な障害に遭遇しました。サービスApache2を再起動すると、次のエラーが表示されます。

 * Restarting web server Apache2
ulimit: 88: error setting limit (Operation not permitted)
ulimit: 88: error setting limit (Operation not permitted)
(13)Permission denied: make_sock: could not bind to address 0.0.0.0:80 no listening sockets available, shutting down
Unable to open logs

私は、Apacheで何が起こっているのかを正確に把握することができませんでした。 ulimitの機能(システム全体のリソース割り当ての監視)は理解していますが、制限の設定が許可されない理由がわかりません。

ここに/ etc/Apache2/sites-available/defaultの内容があります。問題の根本は...

EDITいくつかのフルークでエラーログが機能するようになりました。error.log内で受け取っているエラーは次のとおりです。

問題は、許可エラーの集大成であり、Phusion Passengerが正しくインストールされていなかったことです。

問題は、ルートではなく通常の「ユーザー」として実行しようとしていたことです。これを修正するには、コマンドをSudoで実行するか、Sudoをrootで実行してサービスApache2 restartを実行します。大丈夫なら通常のユーザーとしてApache2を明らかに再起動しますが、RedmineとRubyはulimitの変更を実行するためにエスカレートされたパーミッションが必要です。
