使用Nginx时没有指定输入文件

I just create a server recently, and use Nginx as my web server.

I did : service nginx force-reload

• Reloading nginx configuration nginx [ OK ]

Then I do service nginx status

• nginx is running

Knowing that my site is running, but when I go to it. I see No input file specified. Wired ???

Here is what I have in my /etc/nginx/sites-available/default

server {
    listen 80 default_server;
    server_name default;
    root /default/public;

Can someone please help me fix this ?

I fix this problem by assign my document root to the correct path :

root /home/forge/default/public;

If you see No input file specified., make sure you set your root to the correct path.
