整个Nginx配置必须包含以下部分：http{}、stream{}和events{}处于同一水平。
文件nginx.conf必须在/etc/nginx/nginx.conf中
它应该看起来像（这是无特权的Nginx）

worker_processes  auto;

error_log  /var/log/nginx/error.log notice;
pid        /tmp/nginx.pid;

events {
    worker_connections  1024;
}

http {
    proxy_temp_path /tmp/proxy_temp;
    client_body_temp_path /tmp/client_temp;
    fastcgi_temp_path /tmp/fastcgi_temp;
    uwsgi_temp_path /tmp/uwsgi_temp;
    scgi_temp_path /tmp/scgi_temp;

    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '{"time": "$time_iso8601",...}';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  65;

    #gzip  on;
    include /etc/nginx/conf.d/*.conf;

    server {
        listen       8080;

        location / {
            root   /usr/share/nginx/html;
            index  index.html;
        }
    }
}

stream {
    log_format  upstream_log  '{"time": "$time_iso8601",...}';

    server {
        listen     389;
        proxy_pass db.debian.org:389;
        access_log /var/log/nginx/access.log upstream_log;
    }
}
