1.配置httpd.conf 
监听多个端口

#Listen 12.34.56.78:80 
Listen 8081 
Listen 8082 
Listen 8083

可以通过netstat -n -a查看端口是否开启

2.开启虚拟站点

# Virtual hosts 
#Include conf/extra/httpd-vhosts.conf 
#修改为 
# Virtual hosts 
Include conf/extra/httpd-vhosts.conf

3.php配置

加载php模块,php5apache2_2代表使用的是apache2.2或以上版本 
LoadModule php5_module "c:/php/php5apache2_2.dll" 
PHPIniDir "C:/php" 
配置php文件类型映射 
AddType application/x-httpd-php .php

4。配置conf/extra/httpd-vhosts.conf

<VirtualHost *:8082> 
ServerAdmin webmaster@dummy-host.localhost 
DocumentRoot "C:/PhpDocRoot/Site1" 
ServerName localhost 
ServerAlias localhost 
ErrorLog "logs/dummy-host.localhost-error.log" 
CustomLog "logs/dummy-host.localhost-access.log" common 
<Directory "C:/PhpDocRoot/Site1"> 
Options Indexes FollowSymLinks 
AllowOverride None 
Order allow,deny 
Allow from all 
</Directory> 
</VirtualHost> 
<VirtualHost *:8083> 
ServerAdmin webmaster@dummy-host2.localhost 
DocumentRoot "C:/PhpDocRoot/Site2" 
ServerName localhost 
ErrorLog "logs/dummy-host2.localhost-error.log" 
CustomLog "logs/dummy-host2.localhost-access.log" common 
<Directory "C:/PhpDocRoot/Site2"> 
Options Indexes FollowSymLinks 
AllowOverride None 
Order allow,deny 
Allow from all 
</Directory> 
</VirtualHost>

实际中使用多域名只用80 然后hosts指定localhost2即可：

<VirtualHost *:80>
DocumentRoot E:/SVNRoot/BFGLogic/src
ServerName localhost
ServerAlias localhost
</VirtualHost>

<VirtualHost *:80>
DocumentRoot D:/php/webroot
ServerName localhost2
ServerAlias localhost2
</VirtualHost>

最后重启，如果错误仔细查询log
