Question

应用程序很好，因为如果我从manage.py（runserver）运行它 - 一切正常（响应GET请求）.. 配置：

nginx 1.4.2
python 2.7.3
django 1.5.4
uwsgi 1.9
OS - debian

uwsgi yaml config：

uwsgi:
  chdir: /var/projects/HOA_desk
  module: HOA_desk.wsgi:application
  env: DJANGO_SETTINGS_MODULE=HOA_desk.settings
  socket: /tmp/HOA_desk.sock
  master: 1
  pidfile: /tmp/HOA_desk.pid
  no-orphans: 1
  processes: 2
  max-requests: 5000
  buffer-size: 32768
  harakiri: 30
  reload-mercy: 8
  vacuum: 1
  daemonize: /var/projects/HOA_desk.log
  touch-reload: /var/projects/HOA_desk/hoa_desk_uwsgi.yaml
  stats: 127.0.0.1:9191
  virtualenv: /var/projects/projects_ve/HOA_desk_ve/

nginx.conf

user www-data;
worker_processes  1;

error_log  /var/log/nginx/error.log;
pid        /var/run/nginx.pid;

events {
    worker_connections  1024;
}

http {
    include     mime.types;

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

    sendfile        on;

    keepalive_timeout  65;
    tcp_nodelay        on;

    gzip  on;
    gzip_disable "MSIE [1-6]\.(?!.*SV1)";

    include sites-enabled/*;
}

nginx应用程序配置：

upstream HOA_desk_django {
    server unix:///tmp/HOA_desk.sock;
}

server {
    client_max_body_size 15M;
    listen 80;
    server_name xx.xx-xxxx.xx;
    charset utf-8;
    gzip on;
    expires off;
    access_log /var/projects/HOA_desk_nginx_access.log;
    error_log /var/projects/HOA_desk_nginx_error.log debug;

    location / {
        root /var/projects/HOA_desk;
        uwsgi_pass HOA_desk_django;
        include    uwsgi_params;
    }

    location /static/ {
        add_header X-Static hit;
        autoindex on;
        expires off;
        root /var/projects/HOA_desk/;
    }

    location /uploads/ {
            autoindex on;
            root /var/projects/HOA_desk/;
    }
}

uwsgi_params：

uwsgi_param  QUERY_STRING       $query_string;
uwsgi_param  REQUEST_METHOD     $request_method;
uwsgi_param  CONTENT_TYPE       $content_type;
uwsgi_param  CONTENT_LENGTH     $content_length;

uwsgi_param  REQUEST_URI        $request_uri;
uwsgi_param  PATH_INFO          $document_uri;
uwsgi_param  DOCUMENT_ROOT      $document_root;
uwsgi_param  SERVER_PROTOCOL    $server_protocol;

uwsgi_param  REMOTE_ADDR        $remote_addr;
uwsgi_param  REMOTE_PORT        $remote_port;
uwsgi_param  SERVER_ADDR        $server_addr;
uwsgi_param  SERVER_PORT        $server_port;
uwsgi_param  SERVER_NAME        $server_name;

我发布了uwsgi：uwsgi --uid 33 --gid 33 -y %config_file% Nginx：nginx -c /etc/nginx/nginx.conf

并记录输出：

uwsgi：

然后尝试去获取索引页面（location /），以及.. nginx访问和错误日志输出：

错误日志：

我尝试使用简单的套接字（不是文件套接字） - 一切都是一样的。这个配置文件有什么问题，uwsgi settings或nginx-uwsgi_socket mapping

有问题

Answer 1

问题在于你的内核不支持accept4（）系统调用，而nginx被编译为使用它（如果你的标题暴露它，甚至uWSGI也会使用它）。你使用的是哪个内核？很可能它的系统标题太旧了

Nginx，uwsgi，django和上游在获取/发布时超时
