django+uwsgi+nginx 访问出错

报错如下：

2016/05/13 19:02:40 [error] 11057#0: *162 upstream prematurely closed connection while reading response header from upstream, client: xxx.xxx.xxx.xxx, server: xxx.xxx.xxx.xxx, request: "GET /poweredby.png HTTP/1.1", upstream: "uwsgi://127.0.0.1:8003", host: "xxx.xxx.xxx.xxx:8000", referrer: "http://xxx.xxx.xxx.xxx:8000/" 

uwsgi 配置如下：

[uwsgi] socket = 127.0.0.1:8003 touch-reload=/myblog/reload processes = 2 threads = 4 vacuum = true 

nginx 配置如下：

 server { listen 8000; server_name xxx.xxx.xxx.xxx; root /usr/share/nginx/html; access_log /logs/access.log; error_log /logs/error.log; charset utf-8; # Load configuration files for the default server block. location / { include /etc/nginx/uwsgi_params; uwsgi_pass 127.0.0.1:8003; client_max_body_size 35m; uwsgi_param UWSGI_SCRIPT myblog.wsgi; uwsgi_param UWSGI_CHDIR /myblog; } location /media { alias /path/to/project/media; } location /static { alias /path/to/project/static; } error_page 404 /404.html; location = /40x.html { } error_page 500 502 503 504 /50x.html; location = /50x.html { } } 

views.py 文件内容

#coding:utf-8 from django.shortcuts import render from django.http import HttpResponse # Create your views here. def index(request): return HttpResponse(u"Hello World!!") 

搞了一天了，死活连不上， uwsgi8003 端口正常访问， nginx 代理 8000 端口连不上，端口已经开放，防火墙已经关闭，求解,感激不尽！
