default.conf

 location / {        root   /usr/share/nginx/html;        index  index.html index.htm;    } #默认路径

如上，location为确定路径而设，URL为http://localhost/file.html 等时，服务器将root后的路径加到/file.html前，再查找文件。

location /images/  {        root   /usr/share/nginx;    }

如上，当URL为http://localhost/images/file.png 等时，服务器将root后的路径加入链接中，进行查找，找不到返回404错误。如果URL中没有/images/，服务器将会直接映射到默认路径。

In case something does not work as expected, you may try to find out
the reason in access.log and error.log files in the directory
/usr/local/nginx/logs or /var/log/nginx.

 location ~ \.php$ {        root           /usr/share/nginx/php;#可改        fastcgi_pass   127.0.0.1:9000;        fastcgi_index  index.php;        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;#修改后php才能正确读出        include        fastcgi_params;    }

In PHP, the SCRIPT_FILENAME parameter is used for determining the
script name, and the QUERY_STRING parameter is used to pass request
parameters
