ERR_CONNECTION_REFUSED 我无法连接我的 Ubuntu 服务器

我有一台 Ubuntu 服务器，用于为 Django 项目提供服务。但我无法浏览任何内容。我ERR_CONNECTION_REFUSED在所有浏览器上都遇到错误。

服务器主机、操作系统和应用程序：

  • 数字海洋 Ubuntu 18.04 (LTS) x64
  • nginx 版本：nginx/1.14.0（Ubuntu）
  • ufw 0.36

这是我的 nginx 和 ufw 配置：

$ systemctl status nginx

nginx 站点启用配置文件

server {
   listen 80;
   server_name 188.166.117.124;

    location = /favicon.ico { access_log off; log_not_found off; }
    location /static/ {
        root /home/ahubelkis/personal_web_site/personal_web_site;
    }

    location /media/ {
        root /home/ahubelkis/personal_web_site/personal_web_site;
    }

    location / {
        include /etc/nginx/proxy_params;
        proxy_pass http://unix:/home/ahubelkis/personal_web_site/personal_web_site/personal_web_site.sock;
    }
}

$ sudo systemctl restart nginx

nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

我的配置有什么问题。

答案1

对您的 IP 进行端口扫描（从您的 nginx 配置中收集）表明该主机上唯一开放的端口是 22。

也许可以尝试暂时禁用 UFW sudo ufw disable，然后看看是否可以连接？
