uWSGI nginx错误：连接上游时connect（）失败（111：连接被拒绝）

Question

我在nginx（http://52.xx.xx.xx/）上访问我的IP时遇到了502个网关错误，日志简单地说：

2015/09/18 13:03:37[错误]32636#0:*1连接（）失败（111：拒绝连接），连接到上游，客户端:xx.xx.xx.xx，服务器:xx.xx.xx.xx，请求：“Get/HTTP/1.1”，上游：“UWSGI://127.0.0.1:8000”，主机：“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
    }
}

nginx.conf文件有什么问题吗......如果我使用默认的conf，那么它是工作的。

Answer 1

我通过将uwsgi.ini中的套接字配置从socket=127.0.0.1:3031更改为socket=:3031来解决这个问题。当我在一个Docker容器中运行nginx而在另一个Docker容器中运行uWSGI时，我就面临着这个问题。如果使用命令行启动uWSGI，那么执行UWSGI--socket:3031。

希望这能帮助那些在使用Docker部署Django应用程序时遇到同样问题的人。
