Amazon EC2 上带有 Nginx + uWSGI 的 Django 应用程序

Question

我正在尝试使用 Nginx + uWSGI 在 Amazon EC2 上设置 Django 应用程序。

遵循这些基本教程

https://uwsgi.readthedocs.org/en/latest/tutorials/Django_and_nginx.html http://www.yaconiello.com/blog/setting-aws-ec2-instance-nginx-django-uwsgi-and-mysql/#sthash.TsdnEDM8.oK2geOwb.dpbs

Nginx 欢迎页面显示正常，实例正在运行，负载均衡器正在服务中，Route53 为负载均衡器的别名。但我看不到我的应用...

应用程序似乎正在运行。我已经在本地测试过，它可以工作。

我在终端上输入了

uwsgi --ini myproject_uwsgi.ini

得到这个

我尝试查看 error.log，但我什么也没得到...

Answer 1

在 Amazon EC2 中使用 FastCGI 守护程序的简单示例

    django.sh  -> https://gist.github.com/romuloigor/5707566
    nginx.conf -> https://gist.github.com/romuloigor/5707527

Answer 2

我终于让我的应用程序工作了......首先我让它与 TCP 一起工作，在端口 8001 上进行测试，但静态文件收到错误 404。所以我希望至少让应用程序通过 unix 套接字工作，即使没有静态文件...

我开始将 nginx.conf 和 uwsgi.ini 更改为套接字并开始收到错误 502。比昨天的错误好多了（无法连接）。

通过网络搜索和阅读……找到了这个502 error with nginx + uwsgi +django

不能对任何评论都投票。但是感谢@zzart !!

所以添加到我的 uwsgi.ini

uid = www-data
gid = www-data
chmod-socket = 777

我昨天添加了 uid (www-data)、gid(www-data) 和 chmod-socket = 664 或 644。但在 Amazon EC2 上对我不起作用。但是 777 使它可以工作，并且静态文件也可以工作。

现在我要喝杯啤酒，明天将更改安全组、负载均衡器和 route53。

希望对他人有所帮助。
