我的nginx-error.log文件中出现此错误：

2014/02/17 03:42:20 [crit] 5455#0: *1 connect() to unix:/tmp/uwsgi.sock failed (13: Permission denied) while connecting to upstream, client: xx.xx.x.xxx, server: localhost, request: "GET /users HTTP/1.1", upstream: "uwsgi://unix:/tmp/uwsgi.sock:", host: "EC2.amazonaws.com"

浏览器还显示502错误网关错误。a的输出curl相同，Bad Gateway html

我试图通过将/tmp/uwsgi.sock777的权限更改为修复它。这没有用。我也将自己加入了www-data小组（几个看起来相似的问题表明了这一点）。另外，没有骰子。

这是我的nginx.conf文件：

nginx.conf

worker_processes 1;
worker_rlimit_nofile 8192;

events {
  worker_connections  3000; 
}

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

http {
    include       /etc/nginx/mime.types;
    default_type  application/octet-stream;

    log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
                  '$status $body_bytes_sent "$http_referer" '
                  '"$http_user_agent" "$http_x_forwarded_for"';

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

    sendfile        on; 
    #tcp_nopush     on; 

    keepalive_timeout  65; 

    #gzip  on; 

    include /etc/nginx/conf.d/*.conf;
    include /etc/nginx/sites-enabled/*;
}

我正在用Nginsx和Uwsgi运行Flask应用程序，只是为了解释的透彻。如果有人有任何想法，我将不胜感激。

编辑

我被要求提供我的uwsgi配置文件。因此，我从来没有亲自写过我的nginx或uwsgi文件。我遵循了此处的指南，该指南使用ansible-playbook进行了所有设置。该nginx.conf文件是自动生成的，但是/etc/uwsgi除了和文件夹中的README文件外，什么都没有。我需要为uwsgi创建自己的配置文件吗？我的印象是ansible负责所有这些事情。apps-enabledapps-available

我相信ansible-playbook自从我运行此命令以来，就算出了我的uwsgi配置

uwsgi -s /tmp/uwsgi.sock -w my_app:app

它启动并输出以下内容：
