1.不同的ip
c://windows/sysytem32/etc/host（修改域名访问方式）(//可以没有)
2.httpd.conf文件中配置根目录
<Directory />
Options FollowSymLinks
AllowOverride None
### Order deny,allow
### Deny from all
Order allow,deny
Allow from all
Satisfy all
</Directory>（无权访问问题）
3.在自己的项目中修改的内容如下：
@hosts文件：ip 域名
0.0.0.0 www.XXX.com（//可以没有）
@httpd.conf文件：
NameVirtualHost *:80
<VirtualHost *:80>
ServerAdmin admin@www.pdsying.com

ServerAlias lexiangshow.com
