奇妙な問題に直面しました。サーバーに接続されているドメインを介してサーバーのネットワークアクセス可能ディレクトリにアクセスするとき。それは言う： -
Not Found
The requested URL / was not found on this server.
私のサーバーで（putty経由で）このコマンドを実行すると、Apache Webサーバーが実行されていることを示す複数のプロセスIDが表示されます（正しい）。
root@...:~# pgrep apache
4733
13505
13506
13507
13508
13686
14199
17672
ただし、このコマンドを実行すると、httpd：認識できないサービスと表示されます。
root@...:~# service httpd status
httpd: unrecognized service
他のコマンド出力:-
root@...:~# ps aux|grep -i http
root 29401 0.0 0.0 6460 792 pts/0 S+ 02:21 0:00 grep --color=auto -i http
root@...:~# chkconfig --list | grep httpd
-bash: chkconfig: command not found
root@...:~# find / -name httpd*

"lsof"コマンドを使用して "http"を見つけると、Apache Webサイトプロセスが実際にUbuntuで実行されていることを簡単に確認できます。私：
sudo lsof | grep ':http '
わかりました。
apache2 2202 root 4u IPv6 15516 0t0 TCP *:http (LISTEN)
apache2 22949 www-data 4u IPv6 15516 0t0 TCP *:http (LISTEN)

apache2 22953 www-data 4u IPv6 15516 0t0 TCP *:http (LISTEN)
これはUnbuntuのプロセス名が実際にhttpdではなく「apache2」であることを確認します。
