在解决这个问题之前，我想说明我被这个 502 页面困了两天，需要帮助，我让我的应用程序在数字海洋水滴上完美运行，我决定向它添加另一个应用程序，现在没有人在运行（502 错误）我删除了第二个应用程序，但第一个应用程序没有重新启动

我运行的命令和结果

sudo systemctl status nginx -> 活动：活动（运行）

● gunicorn.service - gunicorn daemon
     Loaded: loaded (/etc/systemd/system/gunicorn.service; enabled; vendor preset: enabled)
     Active: active (running) since Wed 2022-01-12 09:57:21 UTC; 35min ago

sudo nginx -t -> 语法没问题我得到的唯一错误是运行时

须藤尾巴 -100 /var/log/nginx/error.log

connect() to unix:/run/gunicorn.sock failed (111: Connection refused) while connecting to upstream, client: xx-xx-xx-xx server : xx-xx-xx-xx , upstream: "http://unix:/run/gunicorn.sock:/"


当我使用sudo ufw allow 8000允许 port:8000并且我运行
gunicorn --bind 0.0.0.0:8000 config.wsgi 时，我的应用程序运行没有错误

我必须提供我的 gunicorn 配置吗？我还删除了默认的 nginx 配置文件这是我的 nginx 文件

server {

    listen 80 default_server;
    listen [::]:80 default_server;
    server_name IP_ADRESS;
    location = /favicon.ico { access_log off; log_not_found off; }
    location /static/ {
        root /home/taki/kahraba/kahraba;
    }

    location /media/ {
        root /home/taki/kahraba/kahraba;
    }
    location /assets/ {
        root /home/taki/kahraba/kahraba;
    }

    location / {
        include proxy_params;
        proxy_pass http://unix:/run/gunicorn.sock;
        try_files $uri $uri/ =404;
   }
}

我不小心删除了 ngix.conf 文件我有另一个液滴我复制了 nginx.conf 文件并将它传递给这个液滴它是

user www-data;
worker_processes auto;
pid /run/nginx.pid;
include /etc/nginx/modules-enabled/*.conf;

        worker_connections 768;
        # multi_accept on;

#               protocol   imap;
#               proxy      on;
#       }
#}
