Nginx，uwsgi，django和上游在獲取/發布時超時

Question

應用程序很好，因為如果我從manage.py（runserver）運行它-一切正常（響應GET請求）。配置：

• nginx 1.4.2
• python 2.7.3
• Django 1.5.4
• uwsgi 1.9
• 操作系統-Debian

uwsgi yaml配置：

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應用程序配置：

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;

我像這樣啟動uwsgi --uid 33 --gid 33 -y %config_file% ： uwsgi --uid 33 --gid 33 -y %config_file% Nginx： nginx -c /etc/nginx/nginx.conf

並輸出日志：

uwsgi：

然后嘗試去獲取索引頁（位置/），以及..nginx的訪問和錯誤日​​志輸出：

錯誤日志：

我試圖使用簡單的套接字（不是文件套接字）-都是一樣的。 此配置文件中有什么問題， uwsgi settings或nginx-uwsgi_socket mapping ？？

Answer 1

問題在於您的內核在編譯nginx以使用它時不支持accept4（）syscall（如果您的標頭公開了它，甚至uWSGI都將使用它）。 您正在使用哪個內核？ 就您的系統標題而言，它可能太舊了
