Обновление 16.04 LTS повредило апача

У меня была полная функционирующая человечность 14.04 с apache2, подающим ror веб-сайт с Пассажиром, Автономным в обратном прокси. После обновления до 16,04 все это прекратило работать, хотя я могу все еще получить доступ к сайту, использующему 'просто' автономного пассажира.

После БОЛЬШОГО КОЛИЧЕСТВА 'расследований' я прихожу к выводу, что существует что-то не так с основной apache2 установкой на моей машине. Таким образом, я вернулся к основам.

Я создал VirtualHost, который является следующие:

Фунт ServerName DocumentRoot /home/purvez/www/testapp/public

Я сохранил это как файл в /etc/apache2/sites-available/pd.conf

Я затем работал sudo a2ensite pd.conf которые помещают символьную ссылку в /etc/apache2/sites-enabled/pd.conf

У меня есть очень простое index.html который состоит из одной строки следующим образом:

<h1>Test pd site</h1>

и у меня также есть запись в хостах

127.0.0.1  pd

Я перезапустил апачский сервер и перезагрузил машину.

Однако то, когда я перехожу к фунту в веб-странице все, что я получаю, является Страницей Значения по умолчанию Apache2 Ubuntu (начальный бит его имеет этот текст)...

Страница Значения по умолчанию логотипа Apache2 Ubuntu Ubuntu Это работает!

Это - страница приветствия по умолчанию, используемая для тестирования корректной эксплуатации сервера Apache2 после установки в системах Ubuntu. Это основано на эквивалентной странице на Debian, из которого получена упаковка Apache Ubuntu. Если можно прочитать эту страницу, это означает, что Apache сервер HTTP, установленный на этом сайте, работает правильно. Необходимо заменить этот файл (расположенный в /var/www/html/index.html) прежде, чем продолжить управлять Вашим сервером HTTP.

Если Вы - обычный пользователь этого веб-сайта и не знаете то, о чем эта страница, это, вероятно, означает, что сайт в настоящее время недоступен из-за обслуживания. Если проблема сохраняется, свяжитесь с администратором сайта. Обзор конфигурации

и т.д.

Другая безумная вещь состоит в том, даже если я завершаю работу апачского сервиса, я все еще получаю ту же страницу.

В настоящее время это смотрит на меня как apache2, или НЕ работает или если работа просто подает 'Страницу По умолчанию'.

#
# 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
# if it cannot otherwise determine one, such as from filename extensions.
# If your server contains mostly text or HTML documents, "text/plain" is
# a good value.  If most of your content is binary, such as applications
# or images, you may want to use "application/octet-stream" instead to
# keep browsers from trying to display binary files as though they are
# text.
#
# It is also possible to omit any default MIME type and let the
# client's browser guess an appropriate action instead. Typically the
# browser will decide based on the file's extension then. In cases
# where no good assumption can be made, letting the default MIME type
# unset is suggested  instead of forcing the browser to accept
# incorrect  metadata.

DefaultType None

# HostnameLookups: Log the names of clients or just their IP addresses

# ErrorLog: The location of the error log file.
