LinuxQuestions.org - Apache Server fails to start

Code:
# 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 and /usr/share/doc/apache2-common/README.Debian.gz about

# Debian specific hints.

#

#

# Summary of how the Apache 2 configuration works in Debian:

# The Apache 2 web server configuration in Debian is quite different to

# upstream's suggested way to configure the web server. This is because Debian's

# default Apache2 installation attempts to make adding and removing modules,

# virtual hosts, and extra configuration directives as flexible as possible, in

# order to make automating the changes and administering the server as easy as

# possible.



# It is split into several files forming the configuration hierarchy outlined

# below, all located in the /etc/apache2/ directory:

#

#        /etc/apache2/

#        |-- apache2.conf

#        |        `--  ports.conf

#        |-- mods-enabled

#        |        |-- *.load

#        |        `-- *.conf

#        |-- conf.d

#        |        `-- *

#        `-- sites-enabled

#                `-- *

#

#

# * apache2.conf is the main configuration file (this file). It puts the pieces

#  together by including all remaining configuration files when starting up the

#  web server.

#

#  In order to avoid conflicts with backup files, the Include directive is

#  adapted to ignore files that:

#  - do not begin with a letter or number

#  - contain a character that is neither letter nor number nor _-:.

#  - contain .dpkg

#

#  Yet we strongly suggest that all configuration files either end with a

#  .conf or .load suffix in the file name. The next Debian release will

#  ignore files not ending with .conf (or .load for mods-enabled).

#

# * ports.conf is always included from the main configuration file. It is

#  supposed to determine listening ports for incoming connections, and which

#  of these ports are used for name based virtual hosts.

#

# * Configuration files in the mods-enabled/ and sites-enabled/ directories

#  contain particular configuration snippets which manage modules or virtual

#  host configurations, respectively.

#

#  They are activated by symlinking available configuration files from their

#  respective *-available/ counterparts. These should be managed by using our

#  helpers a2enmod/a2dismod, a2ensite/a2dissite. See

#  their respective man pages for detailed information.

#

# * Configuration files in the conf.d directory are either provided by other

#  packages or may be added by the local administrator. Local additions

#  should start with local- or end with .local.conf to avoid name clashes. All

#  files in conf.d are considered (excluding the exceptions noted above) by

#  the Apache 2 web server.

#

# * The binary is called apache2. Due to the use of environment variables, in

#  the default configuration, apache2 needs to be started/stopped with

#  /etc/init.d/apache2 or apache2ctl. Calling /usr/bin/apache2 directly will not

#  work with the default configuration.

# 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

# e.g., www.apache.org (on) or 204.62.129.132 (off).

# The default is off because it'd be overall better for the net if people

# had to knowingly turn this feature on, since enabling it means that

# each client request will result in AT LEAST one lookup request to the

# nameserver.

# ErrorLog: The location of the error log file.

# If you do not specify an ErrorLog directive within a <VirtualHost>
