每一个 web 服务器软件一般默认都会提供一个用于测试的网站，apache 也为用户提供了一个默认网站。默认网站的配置写在默认配置文件中。

#

# 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'.

#

# 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.

#

#apache 软件根目录，apache 安装路径。

ServerRoot "/usr/local/apache"

#

# 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 &lt;VirtualHost&gt;

# directive.

#

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

# prevent Apache from glomming onto all bound IP addresses.

#

# 设置 apache 监听端口及监听 IP 地址

#Listen 12.34.56.78:80

# 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.

#

# 动态共享对象支持, 使用 LoadModule 指令为 apaceh 添加功能模块  --enable-so

# Example:

# LoadModule foo_module modules/mod_foo.so

# '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

# &lt;VirtualHost&gt; definition. These values also provide defaults for

# any &lt;VirtualHost&gt; containers you may define later in the file.

#

# All of these directives may appear inside &lt;VirtualHost&gt; 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

#

# 指定管理员 email 地址

ServerAdmin you@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.

#

# 指定服务器在 DNS 上注册的名称  FQDN

#

# DocumentRoot: The directory out of which you will serve your

# documents. By default, all requests are taken from this directory, but

# symbolic links and aliases may be used to point to other locations.

#

# 使用 DocumentRoot 指定 WEB 站点的根目录

# Possible values for the Options directive are "None", "All",

# ErrorLog: The location of the error log file.

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

#

# The location and format of the access logfile (Common Logfile Format).

# If you do not define any access logfiles within a &lt;VirtualHost&gt;

# container, they will be logged here. Contrariwise, if you *do*

# define per-<VirtualHost> access logfiles, transactions will be

# logged therein and \*not\* in this file.

#

# 定义访问日志路径及日志格式

CustomLog "logs/access_log" common

#

# If you prefer a logfile with access, agent, and referer information

# (Combined Logfile Format) you can use the following directive.

#

#CustomLog "logs/access_log" combined

</IfModule>

# 使用目录映射

<IfModule alias\_module>

#

# URL 重定向

# Redirect: Allows you to tell clients about documents that used to

# exist in your server's namespace, but do not anymore. The client

# will make a new request for the document at its new location.

# Example:

# Redirect permanent /foo http://www.example.com/bar

#URL 重定向  Redirect 方法  选项

# 不同机器重定向将访问 http://IP/abc 的用户 重定向访问 http:/www.baidu.com

Redirect permanent /abc http://www.baidu.com

# 本机内部 URL 重定向 http://IP/123 http://IP/7878 == 注意 ==：被重定向的目录必须存在 比如 7878 必须有

Redirect permanent /123 /7878

#seeother 表示改资源被替换过

Redirect seeother /123 /7878

#gone 表示改资源被移除了

Redirect gone /123

#permanent 永久重定向 301

#temp  临时重定向

#seeother 返回一个 seeother 状态码 (303) 提示这个资源被替代

#gone 返回一个 gone 状态码 (410) 提示这个资源被永久删除了

#

# Alias: Maps web paths into filesystem paths and is used to

# access content that does not live under the DocumentRoot.

# Example:

# Alias /webpath /full/filesystem/path

#

# If you include a trailing / on /webpath then the server will

# require it to be present in the URL. You will also likely

# need to provide a <Directory> section to allow access to

# the filesystem path.

#Alias 将 URI 中的没用了映射到文件系统目录(绝对路径)

# 比如将网站 URL http://ip/abc 访问的 /abc 目录映射到文件系统 /usr/local/apache/htdocs/7878

Alias /abc /usr/local/apache/htdocs/7878

# 需要注意是文件系统路径

#

# ScriptAlias: This controls which directories contain server scripts.

# ScriptAliases are essentially the same as Aliases, except that

# documents in the target directory are treated as applications and

# run by the server when requested rather than as documents sent to the

# client. The same rules about trailing "/" apply to ScriptAlias

# directives as to Alias.

TypesConfig conf/mime.types

#

# AddType allows you to add to or override the MIME configuration

# file specified in TypesConfig for specific file types.

#

#AddType application/x-gzip .tgz

#

# AddEncoding allows you to have certain browsers uncompress

# information on the fly. Note: Not all browsers support this.

#

#AddEncoding x-compress .Z

#AddEncoding x-gzip .gz .tgz

#

# If the AddEncoding directives above are commented-out, then you

# probably should define those extensions to indicate media types:

#

AddType application/x-compress .Z

AddType application/x-gzip .gz .tgz

#

# AddHandler allows you to map certain file extensions to "handlers":

# actions unrelated to filetype. These can be either built into the server

# or added with the Action directive (see below)

#

# To use CGI scripts outside of ScriptAliased directories:

# (You will also need to add "ExecCGI" to the "Options" directive.)

#

#AddHandler cgi-script .cgi

# For type maps \(negotiated resources\):

#AddHandler type-map var

#

# Filters allow you to process content before it is sent to the client.

#

# To parse .shtml files for server-side includes (SSI):

# (You will also need to add "Includes" to the "Options" directive.)

#

#AddType text/html .shtml

#AddOutputFilter INCLUDES .shtml

</IfModule>

#

# The mod_mime_magic module allows the server to use various hints from the

# contents of the file itself to determine its type. The MIMEMagicFile

# directive tells the module where the hint definitions are located.

#

#MIMEMagicFile conf/magic

#

# Customizable error responses come in three flavors:

# 1) plain text 2) local redirects 3) external redirects

#

# Some examples:

#ErrorDocument 500 "The server made a boo boo."

#ErrorDocument 404 /missing.html

#ErrorDocument 404 "/cgi-bin/missing\_handler.pl"

# EnableMMAP and EnableSendfile: On systems that support it,

# broken on your system.
