# Virtual hosts #Include conf/extra/httpd-vhosts.conf
把它改成下面这样：
# Virtual hosts Include conf/extra/httpd-vhosts.conf
意思是启用虚拟主机的设置文件httpd-vhosts.conf，虚拟主机的设置都在这个文件下
设置，不用去改httpd.conf,这样比较清晰。
2.找到Apache的\conf\extra目录下的httpd-vhost.conf这个文件。
打开它的时候里面已经含有像下面这样的内容：
–虚拟主机配置开始
<VirtualHost *:80> ServerAdmin webmaster@dummy-host.localhost DocumentRoot “C:/Program Files/Apache Software Foundation/Apache2.2/docs/dummy-host.localhost” ServerName dummy-host.localhost ServerAlias www.dummy-host.localhost ErrorLog “logs/dummy-host.localhost-error.log” CustomLog “logs/dummy-host.localhost-access.log” common </VirtualHost>
COPY上面这几行，关键是：把
DocumentRoot “”–虚拟主机的目录，即域名对应的根目录
ServerName dummy-host.localhost–你想要的域名。
还要在每个虚拟主机配置开始前加入以下内容：
<Directory “c:\test”>
Options Indexes FollowSymLinks Includes ExecCGI
AllowOverride All
Order allow,deny
Allow from all
</Directory>
其中：
<Directory “c:\test”> –这是你的虚拟主机的被授权的目录
一般与
DocumentRoot “”–虚拟主机的目录，即域名对应的根目录
相同。
Allow from all –这句是重点，只要allow别人才行访问上面定义的目录，
否则在IE或firefox访问时会显示503错误，即禁止访问。
如果你不想在httpd-vhost.conf 里加入
<Directory “c:\test”>
Options Indexes FollowSymLinks Includes ExecCGI
AllowOverride All
Order allow,deny
Allow from all
</Directory>
那么你也可以这样做：
在httpd.conf里找到以下内容：
<Directory />
Options FollowSymLinks
AllowOverride None
Order deny,allow
Deny from all
</Directory>
这是Apache默认的设置，最后一行是这样的
Deny from all
意思是拒绝所有访问对根目录的访问，别人是访问不了你的网站的，
所以要改成
Allow from all
不过还是建议用第一种方法，即修改httpd-vhost.conf的内容，这样比较清楚，也比较安全。
这样apache的设置就完成了，不过还要做下面这一步。
3.还有关键的一步：
这一步不做，一定不行因为你本地的机器没有DNS解析。
找到C:\WINDOWS\system32\drivers\etc目录下的hosts文件
加上这样的记录
127.0.0.1 demoa–这个是你的域名，你要设置多少个虚拟主机，就要加多少行这样的记录。
OK，现在你可以设置N+1个域名了。
也可以参考一下这个地址：http://httpd.apache.org/docs/2.0/vhosts/examples.html
