2）端口相同，ip不同的虚拟主机配置
　　比如服务器有两个IP地址192.168.99.9和192.168.99.10，使用这两个IP创建两台虚拟主机，虚拟主机分别对应的目录为/usr/local/apache/htdocs/web1和/usr/local/apache/htdocs/web2。设置方法如下：
<VirtualHost  192.168.99.9>
ServerName  192.168.99.9:80
DocumentRoot  /usr/local/apache/htdocs/web1
DirectoryIndex  index.html  index.htm
</VirtualHost>
<VirtualHost  192.168.99.10>
ServerName  192.168.99.10:80
DocumentRoot  /usr/local/apache/htdocs/web2
DirectoryIndex  index.html  index.htm
</VirtualHost>
　　2. 配置基于域名的虚拟主机
　　比如有两个域名guoxuemin.cn和tonyguo.com需要使用同一台服务器192.168.99.9，那么可以这样配置：
NameVirtualHost  192.168.99.9
<VirtualHost  www.guoxuemin.cn>
ServerName  www.guoxuemin.cn:80
ServerAdmin  admin@guoxuemin.cn
DocumentRoot  /usr/local/apache/htdocs/web1
DirectoryIndex  index.html  index.htm
ErrorLog  logs/web1/error_log
Customlog  logs/web1/access_log  combined
</VirtualHost>
<VirtualHost  www.tonyguo.com>
ServerName   www.tonyguo.com:80
ServerAdmin  admin@tonyguo.com
DocumentRoot  /usr/local/apache/htdocs/web2
DirectoryIndex  index.html  index.htm
ErrorLog  logs/web1/error_log
Customlog  logs/web1/access_log  combined
</VirtualHost>

<Directory /web/web4>

</Directory>
DirectoryIndex index.html index.php index.htm
</VirtualHost>
<VirtualHost ftp.com>

　　负载均衡
　　#访问test目录时负载均衡
　　在modules目录下：导入mod
/usr/local/apache2/bin/apxs -c -i mod_proxy.c proxy_util.c
/usr/local/apache2/bin/apxs -c -i mod_proxy_balancer.c
/usr/local/apache2/bin/apxs -c -i  mod_proxy_http.c
vi http.conf
