当/ etc/nginx/sites-enabled下没有配置文件时，nginx提供默认网页

Question

从目录/etc/nginx/sites-enabled中删除所有配置文件后，重新引导系统，然后连接到端口80使用浏览器传送具有以下内容的网页。

It works! This is the default web page for this server. The web server software is running but no content has been added, yet. 

这个内容是否由nginx提供，如果是，它从哪里得到？

配置文件/etc/nginx/nginx.conf

的内容你肯定有只nginx的安装在您的系统？这看起来像apache的默认索引页（试图猜测...从Apache Ubuntu < = 2.4.6从Ubuntu 13.10或更旧版本）。

无论如何，请检查Server http响应标头，看看谁在为您的请求提供服务。
