コメントを付けて再DefaultType起動しようとしましたが、より簡単なエラーメッセージが表示されました。
httpdが実行されていません。始めようとしています。 利用可能なリスニングソケットはありません。閉じています。 AH00015: ログをオープンできません。 「再起動」操作が失敗しました。 Apache エラーログにはより多くの情報が含まれる場合があります。
私はapache2.conf下にあります。たとえば、ディレクトリの内容が含まれていないため、内容全体を説明しませんが、sites-enabled次のようになります。
#
# Based upon the NCSA server configuration files originally by Rob McCool.
#
# This is the main Apache server configuration file. It contains the
# configuration directives that give the server its instructions.
# See http://httpd.apache.org/docs/2.2/ for detailed information about
# the directives.
#
# Do NOT simply read the instructions in here without understanding
# what they do. They're here only as hints or reminders. If you are unsure
# consult the online docs. You have been warned.
#
# The configuration directives are grouped into three basic sections:
# 1. Directives that control the operation of the Apache server process as a
# whole (the 'global environment').
# 2. Directives that define the parameters of the 'main' or 'default' server,
# which responds to requests that aren't handled by a virtual host.
# These directives also provide default values for the settings
# of all virtual hosts.
# 3. Settings for virtual hosts, which allow Web requests to be sent to
# different IP addresses or hostnames and have them handled by the
# same Apache server process.
#
# Configuration and logfile names: If the filenames you specify for many
# of the server's control files begin with "/" (or "drive:/" for Win32), the
# server will use that explicit path. If the filenames do *not* begin
# with "/", the value of ServerRoot is prepended -- so "foo.log"
# with ServerRoot set to "/etc/apache2" will be interpreted by the
# server as "/etc/apache2/foo.log".
#
### Section 1: Global Environment
#
# The directives in this section affect the overall operation of Apache,
# such as the number of concurrent requests it can handle or where it
# can find its configuration files.
#
#
# ServerRoot: The top of the directory tree under which the server's
# configuration, error, and log files are kept.
#
# NOTE! If you intend to place this on an NFS (or otherwise network)
# mounted filesystem then please read the LockFile documentation (available
# at <URL:http://httpd.apache.org/docs/2.2/mod/mpm_common.html#lockfile>);
# you will save yourself a lot of trouble.
#
# Do NOT add a slash at the end of the directory path.
#
#ServerRoot "/etc/apache2"
#
# The accept serialization lock file MUST BE STORED ON A LOCAL DISK.
#
# LockFile ${APACHE_LOCK_DIR}/accept.lock
#
# PidFile: The file in which the server should record its process
# identification number when it starts.
# This needs to be set in /etc/apache2/envvars
#
PidFile ${APACHE_PID_FILE}
#
# Timeout: The number of seconds before receives and sends time out.
#
Timeout 300
#
# KeepAlive: Whether or not to allow persistent connections (more than
# one request per connection). Set to "Off" to deactivate.
#
KeepAlive On
#
# MaxKeepAliveRequests: The maximum number of requests to allow
# during a persistent connection. Set to 0 to allow an unlimited amount.
# We recommend you leave this number high, for maximum performance.
#
MaxKeepAliveRequests 100
#
# KeepAliveTimeout: Number of seconds to wait for the next request from the
# same client on the same connection.
#
KeepAliveTimeout 5

# DefaultType is the default MIME type the server will use for a document

アイデア＃1
設定ファイル、特に受信したエラーメッセージをデバッグすることから始めましょう。
[Tue Oct 22 13:34:05.187996 2013] [core:warn] [pid 1925] AH00117: /etc/apache2/apache2.conf ライン 174 で廃止された DefaultType を無視します。
ファイルの74行を具体的に見てみると、廃止された構成/etc/apache2/apache2.confオプションがあるか、その値が変更されて誤った値を指定している可能性があります。
アイデア＃2
起動時のエラーメッセージ：

何かが実際にポート80を使用していることを確認するには、2つのことを試すことができます。
走る
netstat$ netstat -tan | grep :80 tcp 0 0 :::80 :::* LISTEN tcp 0 0 ::ffff:192.168.1.105:80 ::ffff:192.168.1.6:40435 TIME_WAITApacheのリスニングポートを33333に変更
ファイルで
/etc/apache2/ports.confこれを変更してください。Listen 80これに関して：
Listen 33333
答え2
今朝私のサーバーでも同じ問題が発生しました。
AH00015: ログをオープンできません。
Apacheサービスを実行しているユーザーがログフォルダの[セキュリティ]タブにフルアクセスできるようにすることで問題を解決しました。
答え3
利用可能なリスニングソケットはありません。このエラーを閉じると、ポート80を使用するいくつかのアプリケーションが表示されます。どのアプリケーションがポート80を使用しているかを確認する方法はわかりませんが、Apache httpd.conf設定でlocalhostポートを変更できます。設定は次のとおりです。これだ
#Listen 12.34.56.78:80
Listen 80
リスニングポートをたとえば8080に変更して使用を開始します。http://localhost:8080
