Apache的虛擬主機是一種允許在同一臺機器上配置多個不同站點的web伺服器環境的，就是iis一樣可以建立多站點了，但是apache需要在編輯狀態操作，不能像windows iis直接點選幾下就好了，下面我來給各位介紹配置方法。
最平常的大概有3種方法。
第一種：單IP不同埠
第二種：多IP同埠（獨立IP的虛擬空間）
第三種：域名繫結根目錄的方式（共享IP的虛擬空間）
Apache的核心配置檔名是”httpd.conf”，其所存放的路徑在Apache目錄下的conf資料夾下。修改它只需要使用記事本（建議使用其他編輯器，帶行數的那種，方便修改），生效的話只需要儲存httpd.conf，重啟apache即可。
下面多站點支援的話，修改httpd.conf的第187~264行（不同的httpd.conf可能有差異），也就是在ServerAdmin和ServerName那裡，大部分是註釋。下面是主要修改的地方。
注意：如果是伺服器請備份httpd.conf後再修改檔案。

# `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.
#
ServerName www.example.com:80
#
# Deny access to the entirety of your server`s filesystem. You must
# explicitly permit access to web content directories in other
# <Directory> blocks below.
#
<Directory />
AllowOverride All
Require all denied
</Directory>
#
# Note that from this point forward you must specifically allow
# particular features to be enabled – so if something`s not working as
# you might expect, make sure that you have specifically enabled it
# below.
#
#
# 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.
#
DocumentRoot “g:/www”
<Directory “g:/www”>
#
# Possible values for the Options directive are “None”, “All”,
# or any combination of:
# Indexes Includes FollowSymLinks SymLinksifOwnerMatch ExecCGI MultiViews
#
# Note that “MultiViews” must be named *explicitly* — “Options All”
# doesn`t give it to you.
#
# The Options directive is both complicated and important. Please see
# http://httpd.apache.org/docs/2.4/mod/core.html#options
# for more information.
#
Options Indexes FollowSymLinks
#
# AllowOverride controls what directives may be placed in .htaccess files.
# It can be “All”, “None”, or any combination of the keywords:
# Options FileInfo AuthConfig Limit
#
AllowOverride All
#
# Controls who can get stuff from this server.
#
Require all granted
</Directory>

第一種一般是測試環境，畢竟加了埠，如何繫結域名，訪問的時候域名後面也需加埠。
例子分別通過80和8080訪問不同的根目錄。
大概在50幾行有個Listen 80，在下面新增8080埠。
| 程式碼如下 |
複製程式碼 |
|
Listen 80
Listen 8080<VirtualHost *:80>
ServerAdmin admin@myxzy.com
ServerName localhost:80
DocumentRoot “g:/www1”
<Directory “g:/www1”>
Options Indexes FollowSymLinks
AllowOverride All
Require all granted
</Directory>
</VirtualHost>
<VirtualHost *:8080>
ServerAdmin admin@myxzy.com
ServerName localhost:8080
DocumentRoot “g:/www2”
<Directory “g:/www2”>
Options Indexes FollowSymLinks
AllowOverride All
Require all granted
</Directory>
</VirtualHost>

第二種多IP同埠。
IP地址1：192.168.2.2
IP地址2：192.168.1.68
埠同是80埠。
| 程式碼如下 |
複製程式碼 |
|
<VirtualHost 192.168.1.68:80>
ServerAdmin admin@myxzy.com
ServerName localhost:80
DocumentRoot “g:/www1”
<Directory “g:/www1”>
Options FollowSymLinks
AllowOverride All
Require all granted
</Directory>
</VirtualHost>
<VirtualHost 192.168.2.2:80>
ServerAdmin admin@myxzy.com
ServerName localhost:80
DocumentRoot “g:/www2”
<Directory “g:/www2”>
Options FollowSymLinks
AllowOverride All
Require all granted
</Directory>
</VirtualHost>
|
第三種同IP不同域名和根目錄（域名的話修改本地host演示）。
| 程式碼如下 |
複製程式碼 |
|
<VirtualHost 192.168.2.2:80>
ServerAdmin admin@myxzy.com
ServerName www.111cn.net
DocumentRoot “g:/www1”
<Directory “g:/www1”>
Options FollowSymLinks
AllowOverride All
Require all granted
</Directory>
</VirtualHost>
<VirtualHost 192.168.2.2:80>
ServerAdmin admin@myxzy.com
ServerName www.111cn.net
DocumentRoot “g:/www2”
<Directory “g:/www2”>
Options FollowSymLinks
AllowOverride All
Require all granted
</Directory>
</VirtualHost>
