我正在尝试排除服务器无法响应公共请求的原因。我正在运行 nginx，配置文件如下：
ngingx.conf
user www-data;
worker_processes 4;
pid /run/nginx.pid;
events {
worker_connections 768;
# multi_accept on;
}

# server_name_in_redirect off;

我已经启动了 4 个连接到套接字的瘦服务器，如下所示：
RAILS_ENV=production bundle exec thin start --socket /home/rails/apps/mip/production/shared/sockets/thin.1.sock
我可以看到套接字在它们应该在的地方，我尝试删除一个并运行 wgethttp://本地主机，返回：
2018/03/14 10:23:34 [error] 184654#0: *1 connect() to unix:///home/rails/apps/mip/production/shared/sockets/thin.3.sock failed (111: Connection refused) while connecting to upstream, client: 127.0.0.1, server: , request: "GET /login HTTP/1.1", upstream: "http://unix:///home/rails/apps/mip/production/shared/sockets/thin.3.sock:/login", host: "localhost"
仅当我删除了其中一个套接字时，此错误才会出现在日志中，因此它会按应有的方式读取它们。访问日志为：

该日志仅显示本地请求，当我远程访问公共 IP 时它不会注册。
我尝试搜索，但找不到任何关于如何让 nginx 响应访问 IP 地址而不是本地请求的建议。任何帮助都非常感谢
编辑：sudo netstat -tulpn 返回：

答案1
事实证明，我访问的服务器无法直接访问公共请求，而是通过第二台服务器进行路由，而第二台服务器并没有像应该的那样将任何请求转发给 nginx
