如何使用 Apache 和 Django（以及 Docker）配置我的 ProxyPass？

Question

我正在尝试构建一个本地 docker 容器以包含 Django 2/Python 3.7、Apache 2.4 和 MySql 5.7 图像。我在配置我的 Apache 代理以与我的 Django 实例正确交互时遇到问题。我的 apache/my-vhosts.conf 文件是这样的...

<VirtualHost *:80>
    ServerName maps.example.com

    ProxyPreserveHost On
    ProxyPass / http://127.0.0.1/
    ProxyPassReverse / http://127.0.0.1/

</VirtualHost>

我的 Apache 2.4 Dockerfile 看起来像

FROM httpd:2.4
COPY ./my-httpd.conf /usr/local/apache2/conf/httpd.conf
COPY ./my-vhosts.conf /usr/local/apache2/conf/extra/httpd-vhosts.conf
COPY ./maps /usr/local/apache2/htdocs/maps

我的整体 docker-compose.yml 文件看起来像 ...

version: '3'

services:
  web:
    restart: always
    build: ./web
    ports:           # to access the container from outside
      - "8000:8000"
    environment:
      DEBUG: 'true'
    command: /usr/local/bin/gunicorn maps.wsgi:application -w 2 -b :8000

  apache:
    restart: always
    build: ./apache/
    ports:
      - "80:80"
    #volumes:
    #  - web-static:/www/static
    links:
      - web:web

  mysql:
    restart: always
    image: mysql:5.7
    environment:
      MYSQL_DATABASE: 'maps_data'
      # So you don't have to use root, but you can if you like
      MYSQL_USER: 'chicommons'
      # You can use whatever password you like
      MYSQL_PASSWORD: 'password'
      # Password for root access
      MYSQL_ROOT_PASSWORD: 'password'
    ports:
      - "3406:3406"
    volumes:
      - my-db:/var/lib/mysql

volumes:
  my-db:

遗憾的是，当我用 "docker-compose up," 启动所有内容时，我对“http://127.0.0.1/”的请求因 "The proxy server received an invalid response from an upstream server." 而死。在我的 docker-compose 输出中，我看到

apache_1  | [Sun Feb 09 21:07:37.521332 2020] [proxy:error] [pid 11:tid 140081943791360] [client 127.0.0.1:35934] AH00898: Error reading from remote server returned by /
apache_1  | 127.0.0.1 - - [09/Feb/2020:21:06:37 +0000] "GET / HTTP/1.1" 502 341

我认为问题是 apache/my-vhosts.conf 文件。当您将 ProxyPass / 配置为 http://127.0.0.1/ 时，这意味着您代理到 apache 服务的本地主机，而不是 web 服务或在主机上。要代理传递到网络，请改用此 my-vhosts.conf 配置文件：

<VirtualHost *:80>
    ServerName maps.example.com

    ProxyPreserveHost On
    ProxyPass / http://web:8000/
    ProxyPassReverse / http://web:8000/

</VirtualHost>
