502 Bad Gateway nginx/1.20.0 将 django 应用程序部署到 AWS 时出错

Question

我在 Amazon Linux 2 上部署了该应用程序，它似乎没问题，除了当我尝试访问环境 URL 时出现 502 Bad Gateway 错误的部分。

这是我使用的.ebextensions：

01_packages.config

packages:
  yum:
    git: []
    postgresql-devel: []
    libjpeg-turbo-devel: []

commands:
    setuptools:
      command: pip install setuptools --upgrade

db-migrate.config

container_commands:
    01_migrate:
        command: "source /var/app/venv/*/bin/activate && python3 manage.py migrate"
        leader_only: true
option_settings:
  aws:elasticbeanstalk:application:environment:
    DJANGO_SETTINGS_MODULE: multitennant_v2.settings

django.config

option_settings:
  aws:elasticbeanstalk:container:python:
    WSGIPath: multitennant_v2/wsgi.py

我不确定如何以及在何处定义 nginx 命令。

我访问了 nginx 错误日志，它显示如下：

2021/12/29 05:59:11 [error] 691#691: *43880 connect() failed (111: Connection refused) while connecting to upstream, client: 172.31.11.220, server: , request: "GET / HTTP/1.1", upstream: "http://127.0.0.1:8000/", host: "172.31.8.112"
2021/12/29 05:59:17 [error] 691#691: *43882 connect() failed (111: Connection refused) while connecting to upstream, client: 172.31.39.27, server: , request: "GET / HTTP/1.1", upstream: "http://127.0.0.1:8000/", host: "172.31.8.112"

Answer 1

问题出在 djngo.config 文件

而不是上面的应该是：

option_settings:
  aws:elasticbeanstalk:container:python:
    WSGIPath: multitennant_v2.wsgi:application
