比方我现在有二级网站程序bbs，在此目录bbs文件夹里放程序，进入yibanadmin/public目录，把bbs程序的入口文件夹软连接进去改名为bbs。
 ☞ cmd打开路径：cd D:\wwwroot\yiban.mnu.cn\yibanadmin\public
 ☞ CMD管理员方式键入：mklink /J bbs ../../bbs
 ☞ 在bbs文件夹里面配置好路由重写规则后即可实现二级程序路由；
 ☞ bbs程序中有路由控制器yiban；现在可以通过http://yiban.mnu.cn/bbs/yiban进行访问。
 ☞ bbs程序apache重写配置：

          <IfModule mod_rewrite.c>
             RewriteEngine on
             RewriteCond %{REQUEST_FILENAME} !-d
             RewriteCond %{REQUEST_FILENAME} !-f
             RewriteRule ^(.*)$ /bbs/index.php?s=/$1 [QSA,PT,L]
         </IfModule>
