Nginx错误日志

Question

我有一个数字海洋液滴，它包含了我的Meteor应用程序，但是我一直在我的/var/log/nginx日志中得到这个错误：

2015/03/11 12:58:46 [error] 2114#0: *423 "/usr/share/nginx/www/index.html" is not found (2: No such file or directory), client: 199.223.125.109, server: nickeleres.com, request$

我的应用程序不需要入口点；除此之外，我不知道这个指令从何而来。我遵循这一指南：

https://www.digitalocean.com/community/tutorials/how-to-deploy-a-meteor-js-application-on-ubuntu-14-04-with-nginx

我甚至从/etc/nginx/sites-available/nickeleres中删除了这些行

#root /usr/share/nginx/html; # root is irrelevant
#index index.html index.htm; # this is also irrelevant

有人能给我指明正确的方向吗？

编辑我的nginx配置

           server_tokens off; # for security-by-obscurity: stop displaying nginx version

            # this section is needed to proxy web-socket connections
            map $http_upgrade $connection_upgrade {
                default upgrade;
                ''      close;

            # HTTP

Answer 1

/usr/share/ nginx /www/index.html是nginx显示的内容，如果您仍然在/etc/nginx/site中拥有默认的符号链接-启用/。

Nginx将/etc/nginx/site中的所有配置文件加载到启用/中，这使得在同一服务器上为不同站点提供信任变得非常容易。通常的方法是将这些配置文件存储在/etc/nginx/site中-可用/，并将一个符号链接放到要加载到/etc/nginx/site中的配置文件中-启用/etc/nginx/site。默认情况下，在/etc/ nginx /site中有一个名为default /etc/nginx/site的文件--可用/在/etc/nginx/site中有一个指向它的符号链接--因此未配置的服务器将显示默认的nginx index.html。

删除/etc/ nginx /sites启用/default将删除符号链接(同时保留实际的配置文件，以防以后需要它)，从而防止nginx试图加载/usr/share/nginx/www/index.html (我猜您已经删除了它)。
