DigitalOcean为django实例添加域名，使用nginx和gunicorn

Question

我已经在digitalocean上设置了一键安装django，并添加了一个域名。我还试图在网站上线前添加一个子域。我编辑了nginx conf文件，如下所示

server {
    listen 80 default_server;
    listen [::]:80 default_server ipv6only=on;

    root /usr/share/nginx/html;
    index index.html index.htm;

    client_max_body_size 4G;
    server_name beta.kazi-connect.com;

    keepalive_timeout 5;

    # Your Django project's media files - amend as required
    location /media  {
        alias /home/django/django_project/django_project/media;
    }

    # your Django project's static files - amend as required
    location /static {
        alias /home/django/django_project/django_project/static;
    }

    # Proxy the static assests for the Django Admin panel
    location /static/admin {
       alias /usr/lib/python2.7/dist-packages/django/contrib/admin/static/admin/;
    }

    location / {
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header Host $host;
            proxy_redirect off;
            proxy_buffering off;

            proxy_pass http://app_server;
    }

}

upstream app_server {
    server unix:/home/django/gunicorn.socket fail_timeout=0;
}

并重新启动了nginx和gunicorn，然而，当我访问子域时，我得到了一个502坏网关错误。

Nginx日志显示gunicorn有一个问题。

塞缪尔的回答是对的。问题是域名没有包含在ALLOWED_HOSTS中。在django_project/settings.py中，搜索以下代码。

# Discover our IP address
ALLOWED_HOSTS = ip_addresses()

将您的域名添加到ALLOWED_HOSTS，例如

ALLOWED_HOSTS.extend(["xyz.com"])
