按照慕课Wang的讲解，配置Apache2.4.9版本，改到后来运行不了wamp了，代码如下：请问哪里出错了，求大神指点

#

# This is the main Apache HTTP server configuration file.  It contains the

# configuration directives that give the server its instructions.

# See <URL:http://httpd.apache.org/docs/2.4/> for detailed information.

# In particular, see 

# <URL:http://httpd.apache.org/docs/2.4/mod/directives.html>

# for a discussion of each configuration directive.

#

# 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.  

#

# 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 "logs/access_log"

# with ServerRoot set to "/usr/local/apache2" will be interpreted by the

# server as "/usr/local/apache2/logs/access_log", whereas "/logs/access_log" 

# will be interpreted as '/logs/access_log'.

#

# NOTE: Where filenames are specified, you must use forward slashes

# instead of backslashes (e.g., "c:/apache" instead of "c:\apache").

# If a drive letter is omitted, the drive on which httpd.exe is located

# will be used by default.  It is recommended that you always supply

# an explicit drive letter in absolute paths to avoid confusion.

ServerSignature On

ServerTokens Full

#

# ServerRoot: The top of the directory tree under which the server's

# configuration, error, and log files are kept.

#

# Do not add a slash at the end of the directory path.  If you point

# ServerRoot at a non-local disk, be sure to specify a local disk on the

# Mutex directive, if file-based mutexes are used.  If you wish to share the

# same ServerRoot for multiple httpd daemons, you will need to change at

# least PidFile.

#

ServerRoot "D:/wamp/bin/apache/apache2.4.9"

Define APACHE24 Apache2.4

#

# Mutex: Allows you to set the mutex mechanism and mutex file directory

# for individual mutexes, or change the global defaults

#

# Uncomment and change the directory if mutexes are file-based and the default

# mutex file directory is not on a local disk or is not appropriate for some

# other reason.

#

# Mutex default:logs

#

# Listen: Allows you to bind Apache to specific IP addresses and/or

# ports, instead of the default. See also the <VirtualHost>

# directive.

#

# Change this to Listen on specific IP addresses as shown below to 

# prevent Apache from glomming onto all bound IP addresses.

#

#Listen 12.34.56.78:80

Listen 0.0.0.0:80

Listen [::0]:80

# Dynamic Shared Object (DSO) Support

# To be able to use the functionality of a module which was built as a DSO you

# have to place corresponding `LoadModule' lines at this location so the

# directives contained in it are actually available _before_ they are used.

# Statically compiled modules (those listed by `httpd -l') do not need

# to be loaded here.

# 'Main' server configuration

#

# The directives in this section set up the values used by the 'main'

# server, which responds to any requests that aren't handled by a

# <VirtualHost> definition.  These values also provide defaults for

# any <VirtualHost> containers you may define later in the file.

#

# All of these directives may appear inside <VirtualHost> containers,

# in which case these default settings will be overridden for the

# virtual host being defined.

# ServerAdmin: Your address, where problems with the server should be

# e-mailed.  This address appears on some server-generated pages, such

# as error documents.  e.g. admin@your-domain.com

#

ServerAdmin admin@example.com

#

# ServerName gives the name and port that the server uses to identify itself.

# This can often be determined automatically, but we recommend you specify

# it explicitly to prevent problems during startup.

# If your host doesn't have a registered DNS name, enter its IP address here.
