uWSGI nginx错误：connect（）失败（111：连接被拒绝），同时连接到上游

我在访问nginx上的IP时遇到了502个网关错误（ http：//52.xx.xx.xx/ ），日志只是这样说的：

2015/09/18 13:03:37 [error] 32636#0: *1 connect() failed (111: Connection refused) while connecting to upstream, client: xx.xx.xx.xx, server: xx.xx.xx.xx, request: "GET / HTTP/1.1", upstream: "uwsgi://127.0.0.1:8000", host: "xx.xx.xx.xx" 

我的nginx.conf文件

 # the upstream component nginx needs to connect to upstream django { # server unix:///path/to/your/mysite/mysite.sock; # for a file socket server 127.0.0.1:8000; # for a web port socket (we'll use this first) } # configuration of the server server { # the port your site will be served on listen 80; # the domain name it will serve for server_name xx.xx.xx.xx; # substitute your machine's IP address or FQDN charset utf-8; access_log /home/ubuntu/test_django/nginx_access.log; error_log /home/ubuntu/test_django/nginx_error.log; # max upload size client_max_body_size 75M; # adjust to taste # Django media location /media { alias /home/ubuntu/test_django/static/media/; # your Django project's media files - amend as required } location /static { alias /home/ubuntu/test_django/static/; # your Django project's static files - amend as required } # Finally, send all non-media requests to the Django server. location / { uwsgi_pass django; include /home/ubuntu/test_django/uwsgi_params; # the uwsgi_params file you installed } } 

有没有什么错误的nginx.conf文件…..如果我使用默认的conf然后它工作。

• 如何在Ubuntu上优化uWSGI python app + nginx？
• 如何在nginxconfiguration中获取多个头部访问控制 – 允许 – 凭据？
• Chrome手机加载PHP两次？
• Django gunicorn nginx“读取响应头时由对方重置连接”
• Flask + sklearn不能joblib.load AttributeError“模块”对象没有属性

 include /home/ubuntu/test_django/uwsgi_params; 

 include /etc/nginx/uwsgi_params; 

 include /etc/nginx/uwsgi_params; 

 location /sistema { include /etc/nginx/uwsgi_params; uwsgi_pass unix://path/sistema.sock; }
