Eu tinha um ubuntu 14.04 em pleno funcionamento com o apache2 servindo um site ror com o Passenger Standalone no proxy reverso. Depois de atualizar para o 16.04, tudo parou de funcionar, embora eu ainda possa acessar o site usando o 'apenas' passageiro autônomo.
Depois de muitas investigações, chego à conclusão de que há algo errado com a instalação básica do apache2 em minha máquina. Então voltei ao básico.
Eu criei um VirtualHost que é o seguinte:
Nomedoservidor pd
DocumentRoot /home/purvez/www/testapp/public
Eu salvei isso como um arquivo em /etc/apache2/sites-available/pd.conf
Em seguida, executei sudo a2ensite pd.conf , que colocou um link simbólico em /etc/apache2/sites-enabled/pd.conf
Eu tenho um index.html muito simples, que consiste em uma única linha da seguinte forma:
<h1>Test pd site</h1>
e eu também tenho uma entrada nos hosts
127.0.0.1 pd
Eu reiniciei o servidor apache e reiniciei a máquina.
No entanto, quando vou para o pd em uma página da web, tudo o que eu obtenho é a Página Padrão do Apache2 Ubuntu (a parte inicial tem este texto) ...
Página inicial do Ubuntu Logo Apache2 Ubuntu Funciona!
Esta é a página padrão de boas-vindas usada para testar a operação correta do servidor Apache2 após a instalação nos sistemas Ubuntu. Ele é baseado na página equivalente no Debian, da qual o pacote do Ubuntu Apache é derivado. Se você puder ler esta página, isso significa que o servidor HTTP Apache instalado neste site está funcionando corretamente. Você deve substituir este arquivo (localizado em /var/www/html/index.html ) antes de continuar a operar seu servidor HTTP.
Se você é um usuário normal deste site e não sabe o que é esta página, isso provavelmente significa que o site está indisponível no momento devido à manutenção. Se o problema persistir, entre em contato com o administrador do site. Visão Geral da Configuração
etc.
A outra coisa louca é que mesmo que eu desligue o serviço do apache eu ainda recebo a mesma página.
Atualmente, parece-me que o apache2 NÃO está funcionando ou se o trabalho está apenas exibindo a "Página padrão".
---------- Edite 1 para @eldergeek que queria o apache2.conf completo
#
# 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.

Tente isso como pd.conf

Reinicie o Apache e tente.
Você tem algo mais em execução na porta 80 (lsof -i: 80 como root) ou diretivas de escuta sobrepostas (para a porta 80) em seus vários arquivos de configuração (grep -ri Listen / etc / apache2)
