在ubuntu下配置虚拟主机：

1.        以root用户命令行进入/etc/apache2/sites-available/目录。

2.        创建虚拟主机配置文件，以域名命名创建文件，如aaron.com,你需要创建文件aaron，

NameVirtualHost *:9011

<VirtualHost *:9001>
ServerAdmin master@test.com  #邮件地址
ServerName www.aaron.com  #域名
DocumentRoot /var/www/aaron  #虚拟主机目录
<Directory /var/www/aaron>
Options Indexes FollowSymLinks MultiViews
               AllowOverride None#如果配置url重写，则将该行改为AllowOverride All
                Order allow,deny
                allow from all
</Directory>

 ErrorLog/var/log/apache2/www_test_com_error.log
       LogLevel warn
       CustomLog /var/log/apache2/www_test_com_access.log combined
       ServerSignature On
</VirtualHost>

3.命令行进/etc/apache2/目录

vi posts.conf

增加两行文字，配置相应的监听端口。

NameVirtualHost *:9001

Listen 9001

4.在/etc/apache2下执行  a2ensite aaron

此命令是在/etc/apache2/sites-enabled目录下建立一个指向/etc/apache2/site-avaiable目录下wwwtest的软连接

执行/etc/init.d/apache2reload 执行配置文件重新载入

不报错说明配置成功

下面说在windows下如何配置apache的虚拟主机：

将include前的#去掉
 www.it165.net

保存修改后的httpd/conf

4、配置httpd-vhosts.conf

打开httpd-vhosts.conf文件，将该文件内容指定为：

#
# 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.
#
<VirtualHost *:80>
    ServerAdmin webmaster@dummy-host.test
    DocumentRoot "D:/WorkSpace/ApacheWebs2"
    ServerName www.test1.com
    ServerAlias www.dummy-host.test
    ErrorLog "logs/dummy-host.test-error.log"
    CustomLog "logs/dummy-host.test-access.log" common
</VirtualHost>
<Directory "D:/WorkSpace/ApacheWebs2">
      Options Indexes MultiViews
      AllowOverride None
      Order allow,deny
      Allow from all
</Directory>

<VirtualHost *:80>
    ServerAdmin webmaster@dummy-host2.test
    DocumentRoot "D:/WorkSpace/ApacheWebs3"
    ServerName www.test2.com
    ErrorLog "logs/dummy-host2.test-error.log"
    CustomLog "logs/dummy-host2.test-access.log" common
</VirtualHost>
<Directory "D:/WorkSpace/ApacheWebs3">
      Options Indexes MultiViews
      AllowOverride None
      Order allow,deny
      Allow from all
</Directory>

上面的配置文件中设置了两个虚拟主机，对应的服务器名及web站点目录名分别为：

Servername： www.test1.com　　　　　－＞　　　D:/WorkSpace/ApacheWebs2

Servername：www.test2.com　　　　　－＞　　　D:/WorkSpace/ApacheWebs3

[Directory]的标签使用来设置目录的访问权限的，如果不设置的话，会出现403的错误。

如果不希望站点显示目录的话，可以将[Directory]中options的indexes前加上［－］，即：

<Directory "D:/WorkSpace/ApacheWebs3">
      Options -Indexes MultiViews
      AllowOverride None
      Order allow,deny
      Allow from all
</Directory>

以上配置结束后，保存文件．

并重新启动Ａｐａｃｈｅ服务即可．

如果是本地调试的话，还需要修改一下Ｈｏｓｔｓ文件，否则的话。。。，你自己试试就知道了

打开c:\windows\system2\drivers\etc\Hosts文件

加入以下代码：

打开IE，分别输入：

http://www.test1.com

http://www.test2.com

就可以看到效果了。
