CentOS 6 64ビットのVPSへのクリーンインストール。すでにインストールされているhttpdを使用しようとするだけでインストールされるあらゆる種類のパッケージ.
my case:
[root@bucch ~]# service httpd status
httpd is stopped
[root@bucch ~]# service httpd start
Starting httpd: [ OK ]
[root@bucch ~]# service httpd status

/etc/httpd/conf/httpd.confに次のディレクティブがあります。
PidFile /var/run/httpd/httpd.pid
そして/ etc/sysconfig/httpdにこれがあります:
PIDFILE=/var/run/httpd/httpd.pid
/ etc/sysconfig/iptablesには次のものがあります。
-A INPUT -p tcp -m tcp --dport 80 -j ACCEPT
-A INPUT -p tcp -m tcp --dport 443 -j ACCEPT
ディレクトリ/ var/run/httpdには、次のような権限があります。
chmod a+rx
これは、httpdサービスを開始する前後で同じnetstat-plantの出力です。

ホスティングプロバイダーにサポートリクエストを送信し、2日後に問題を修正しました。チケットは次のメッセージで閉じられました:"こんにちは、問題はノードにありました。ノードのカーネルで変更を行う必要がありました。"
同じ構成(およびより多くのパッケージ)で、Apacheは完全に機能しています。とにかくみんなありがとう!
