Linux Nginx错误日志

我有一个数字海洋液滴，其中包含我的Meteor应用程序，但我在我的/var/log/nginx日志中不断发现这个错误：

2015/03/11 12:58:46[错误]21140:*423/usr/share/nginx/www/index.html未找到2:没有此类文件或目录，客户端：199.223.125.109，服务器：nickeleres.com，请求$

我的申请不需要进入点；除此之外，我不知道这个指令在我的配置中来自哪里。我遵循这个指南：

我甚至从/etc/nginx/sites available/nickeleres中注释了这些行：

有人能给我指出正确的方向吗

编辑我的nginx配置

/usr/share/nginx/www/index.html是nginx在/etc/nginx/sites enabled/中显示的默认符号链接

Nginx加载/etc/Nginx/sites enabled/中的所有配置文件，这使得在同一台服务器上为不同的站点配置变得很容易。通常的方法是将这些配置文件存储在/etc/nginx/sites available/中，并在/etc/nginx/sites enabled/中添加要加载的配置文件的符号链接。默认情况下，在/etc/nginx/sites available/中有一个名为default的文件，在/etc/nginx/sites enabled/中有一个指向该文件的符号链接，因此未配置的服务器将显示默认的nginx index.html

---

删除/etc/nginx/sites enabled/default将删除符号链接，同时保留实际的配置文件，以备以后需要，防止nginx尝试加载/usr/share/nginx/www/index.html，我猜您已经删除了该文件。

在原始帖子中添加了什么是浏览器请求URL？/etc/nginx/sites enabled/default仍然存在吗？如果不使用它，请记住删除它，否则您可能会有冲突的指令。
