我有以下配置，Varnish 充当面向外部的端点 (NGINX) 和 Apache 之间的缓存。

+-------+        +-------+       +------+
| NGINX |  +---> |Varnish| +---> |Apache|
+-------+        +-------+       +------+

当我从浏览器调用它时，我无法匹配我的 Apache VirtualHost 配置。我的（单个）VirtualHost 的配置如下所示：

<VirtualHost *:80>
    ServerName fabrikam.com
    ServerAlias fabrikam.com
    ServerAdmin myemailaddress
    DocumentRoot /var/www/html
    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access-mycustomlog.log combined
</VirtualHost>

这是 Apache 版本：

root@localhost:/etc/apache2# apache2 -v
Server version: Apache/2.4.7 (Ubuntu)
Server built:   Jan 14 2016 17:45:23

症状

当我访问https://fabrikam.com时，它没有给我文件夹的根/var/www/html目录。相反，它尝试访问 的根目录/var/www，并且因为我禁用mod_index了 ，它给了我一个 HTTP 404 Not Found 错误。

关于如何让这个 VirtualHost 配置正确“匹配”的任何想法？当我访问 fabrikam.com 时，它应该转到/var/www/html文件夹，而不是文件/var/www中apache2.conf。
