我没有让我的服务器找到我的网站。
我正在使用 Linux、Apache2 和 Aptana Studio 进行开发。
当我在浏览器上运行时，http://example/它运行正常，说“它有效！这是此服务器的默认网页......”但我已经有一个 html 文件，它应该读取该文件而不是显示该消息。即使这样做：http://example/index.html，它也向我展示了相同的结果。

这是我的 Apache 配置文件：
# 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
#
# * 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 or .local.conf to avoid name
# clashes. All files in conf.d are included
#
# * 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.
# Global configuration
#
#
# 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.

# 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.

如果 Apache2 配置为转到该文件夹并将其视为服务器，为什么它不读取该文件夹？我的网站在：
