为什么 nginx 安装后，没有修改任何配置文件，只在/var/www/html 下新建一个文件夹和一个 html 文件，就能通过 “http://ip/文件夹” 访问了

nginx -V 看看编译选项

为什么 iPhone 插了手机卡后，没有填写任何填表文件，只要在 通话 App 下拨号 13412341234 就能通过通话拨号了呢？

默认绑定了 80 端口，在就在 /etc/nginx/下的文件夹里，你好好找找，我记不清是哪个了

/etc/nginx/sites-available/default

不同发行版本，打包都不一样，ubuntu 里的 nginx.conf 默认有 include 的

include /etc/nginx/conf.d/*.conf;
include /etc/nginx/sites-enabled/*;


这不是还有配置嘛，都是空的？

默认 nginx.conf 里面应该有 include /etc/nginx/conf.d/*.conf; 我记得 /etc/nginx/conf.d 里面有个 default.conf

是在这个下面找到了 /etc/nginx/sites-enabled/*

多谢各位

/etc/nginx/sites-available 这里列出你的全部网站
/etc/nginx/sites-enabled 这里是启用你的网站，实际是建立一个 link 到 available 里面的文件
