实验目标：在apache实现基于域名的虚拟主机

实验用的XAMPP版本为1.7.7，内含apache版本为2.2.21

实验前准备：

1. 为了测试不同的域名，在Windows/System32/drivers/etc/下觅得hosts文件，在其中添加实验用的域名若干，如 -

127.0.0.1   test1.net

127.0.0.1   test2.net

如此，则在浏览器中输入该俩域名时，Windows将其解析为127.0.0.1本地地址。即，在浏览器中访问localhost, test1.net, test2.net均可访问XAMPP的欢迎页。

2. 在apache目录下建立目录，以放置您不同的网站。为保护XAMPP原有的htdocs中的欢迎页内容，实验另外建立了与htdocs平级的htdocs1目录，在其下建立了test1.net, test2.net两个子目录用以放置实验用的网站。如下 -

apache/htdocs1/test1.net - 放置test1.net网站内容

apache/htdocs1/test2.net - 放置test2.net网站内容

在这两个目录中各新建hello world一网页 index.html，内容 -

实验步骤：

1. 找到apache/conf/httpd.conf, 将其中的

ServerAdmin

ServerName

DocumentRoot

注释掉。

2. 在httpd.conf中，找到行

如被注释则解注。该文件记载了虚拟主机的参数。[以前虚拟主机参数是直接填写在httpd.conf中的，为了更好地组织文件，将其分离出去，类似于某些编程语言一样。因此httpd.conf中include它，即相当于把它的内容填在了httpd.conf中。]

3. 这个httpd-vhosts.conf文件格式基本如下 -

#blah-blah
NameVirtualHost *:80

#blah-blah
#blah-blah
< VirtualHost  *:80 >
    ServerAdmin XXXXXXXX
    DocumentRoot "XXXXXXXX"
    ServerName XXXXXXX
    ServerAlias XXXXXX
    ErrorLog "logs/XXXXXX-error.log"
    CustomLog "logs/XXXXXXX-error.log" combined   
</ VirtualHost >

需要修改的，就是<VirtualHost>中的参数了。这个可以参见apache官方文档。根据实验域名，可以增加两个<VirtualHost>：

< VirtualHost  *:80 >
    ServerAdmin adm@test1.net
    DocumentRoot "C:/xampp/htdocs1/test1.net"
    ServerName test1.net
    ServerAlias www.test1.net
    ErrorLog "logs/test1-error.log"
    CustomLog "logs/test1-access.log" combined
    
     < Directory  "C:/xampp/htdocs1/test1.net" >
    order allow,deny
    allow from all
     </ Directory >    
</ VirtualHost >

< VirtualHost  *:80 >
    ServerAdmin adm@test2.net
    DocumentRoot "C:/xampp/htdocs1/test2.net"
    ServerName test2.net
    ServerAlias www.test2.net
    ErrorLog "logs/test1-error.log"
    CustomLog "logs/test1-access.log" combined
    
     < Directory  "C:/xampp/htdocs1/test2.net" >
    order allow,deny
    allow from all
     </ Directory >    
</ VirtualHost >

注意，如果不在各VirtualHost中定义Directory的可访问性，你将遇到的是Access Forbidden!就连原来的localhost也是。

4. 由于之前注释掉了httpd.conf中的ServerName, DocumentRoot等，为了仍然能以localhost访问原XAMPP欢迎页，就在增加一个VirtualHost，如下 -

< VirtualHost  *:80 >
    ServerAdmin adm@localhost
    DocumentRoot "C:/xampp/htdocs"
    ServerName localhost
    
    ErrorLog "logs/localhost-error.log"
    CustomLog "logs/localhost-access.log" combined
    
     < Directory  "C:/xampp/htdocs" >
    order allow,deny
    allow from all
     </ Directory >    
</ VirtualHost >

为了避免出错，把它放置在第一个Virtualhost位置。

至此，apache基于域名的虚拟主机配置完成。可以通过http://localhost访问XAMPP欢迎页，通过http://test1.net和http://test2.net访问各自的主页。

#
# Virtual Hosts
#

# If you want to maintain multiple domains/hostnames on your
# machine you can setup VirtualHost containers for them. Most configurations
# use only name-based virtual hosts so the server doesn't need to worry about
# IP addresses. This is indicated by the asterisks in the directives below.
#
# Please see the documentation at 
# <URL:http://httpd.apache.org/docs/2.2/vhosts/>
# for further details before you try to setup virtual hosts.
#
# You may use the command line option '-S' to verify your virtual host
# configuration.

#
# Use name-based virtual hosting.
#
NameVirtualHost *:80

#
# VirtualHost example:
# Almost any Apache directive may go into a VirtualHost container.
# The first VirtualHost section is used for all requests that do not
# match a ServerName or ServerAlias in any <VirtualHost> block.
#
