反向代理到另一台计算机

问题描述

我正在尝试执行的操作的说明：

我在IP 192.168.1.10(扩展坞反向代理)和192.168.1.20(其他服务)上有两台服务器。我希望10将请求重定向到20(这些请求中的许多都是使用SSL的)。

示例：

例如_内部网	→	192.168.1.10	→	https://example_internal.host.com
Example_Extraal.Host.com	→	192.168.1.20	→	https://example_external.host.com

docker-pose.yaml：

version: '3'

networks:

     driver: bridge

SCM-Proxy/Dockerfile：

FROM nginx:1.15-alpine
COPY nginx.conf /etc/nginx/nginx.conf

SCM-Proxy/nginx.conf：

worker_processes 1;

events {
  worker_connections 1024;
}

http {

    sendfile on;
    client_max_body_size 0;
    chunked_transfer_encoding on;

    server {
        listen 80;
        location / {
            proxy_pass        http://localhost:80;
            proxy_redirect    off;
            proxy_set_header  Host              $http_host;   # required for docker client's sake
            proxy_set_header  X-Real-IP         $remote_addr; # pass on real client's IP
            proxy_set_header  X-Forwarded-For   $proxy_add_x_forwarded_for;
            proxy_set_header  X-Forwarded-Host $http_host;
            proxy_set_header  X-Forwarded-Proto $scheme;
        }
    }
}

(我在一些地方读到，我必须输入"；/etc/hosts"；的域名解析，类似于"；192.168.1.20 Example_Exteral.Host.com"；)

事实是，这是我第一次使用这项技术，我还没有找到很多信息，我找到的东西很难理解。

评论：

缺少某些详细信息，例如nginx.conf文件自动获取server_name字段中的example_external.host.com，但它将在以后使用。

另一方面，您必须小心DEFAULT_HOST=如果声明它，您可能会收到错误。我建议先对它进行注释，直到它起作用，然后再取消对它的注释

我建议使用此命令：docker-compose up -d --remove-orphans --build
