怎么给某个文件设置端口

如何给某个文件设置端口？

我用的是WAMP环境，在apache 的 http-vhosts.conf里加了以下一段，但提示无法连接数据库，求指点

NameVirtualHost *:8682

<VirtualHost *:8682>

  ServerAdmin webmaster@dummy-host.hleclerc-PC.ingenidev

  ServerName xxxx.xxxx.org

  DocumentRoot “C:\wamp\www\guest”

  <Directory “C:\wamp\www\guest”>

  Order Deny,Allow

  Deny from all

  Allow from all

  </Directory>

  Alias /api “C:/wamp/www/api/”

  <Directory “C:\wamp\www\api/”>

  Order Deny,Allow

  Deny from all

  Allow from all

  </Directory>

  ErrorLog “C:\wamp\logs\dummy-flowbase-error.log”

  CustomLog “C:\wamp\logs\dummy-flowbase-access.log” common

</VirtualHost>

编辑httpd.conf，查找Include conf/extra/httpd-vhosts.conf，把前面注释符号“#”删掉
