Question

当我访问该站点时，我收到了错误的网关502错误。这就是我的配置

/etc/nginx/sites-enabled/django

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

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 _;

    keepalive_timeout 5;

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

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

    # Proxy the static assests for the Django Admin panel
    location /static/admin {
       alias /usr/local/lib/python3.6/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;
    }

}

运行service gunicorn status时，我可以看到此信息：

我可以在nginx错误日志中看到：

2020/07/19 19:26:00 [crit] 9039#9039: *15 connect() to unix:/home/django/gunicorn.socket failed (2: No such file or directory) while connecting to upstream, client: 84.48.191.11, server: _, request: "GET / HTTP/1.1", upstream: "http://unix:/home/django/gunicorn.socket:/", host: "161.35.197.193"

有什么建议吗？我调查了类似的问题，但无法解决我的问题。

Answer 1

似乎我有一个错误502，因为它无法打开数据库。我已经在Gunicorn日志中找到了有关它的更多信息。

Django 2.2的Gunicorn / Nginx配置提供了502错误的网关
