1.测试

  2. python manage.py runserver
  4. python manage.py runserver 0.0.0.0
  5. python manage.py runserver 0.0.0.0:8000  --noreload
  6. python3 manage.py runserver 8000

2.error

里面有错误函数里

您可能正在请求不带斜杠的 URL，并且APPEND_SLASH在 settings.py 中设置为 True（默认值），因此 Django 正在重定向到包含斜杠的 URL。

nginx+django 502 bad gateway

修改直接代码上传，本地测试成功，服务端502
查看了cat /usr/local/nginx/logs/error.log uwsgi.log
发现修改代码区少安装包
重启nginx，uwsgi
重启 reboot，nginx，uwsgi

uwsgi 有问题

RuntimeError: populate() isn’t reentrant

This is caused by a bug in your Django settings somewhere. Unfortunately, Django’s hiding the bug behind this generic and un-useful error message.
To reveal the true problem, open django/apps/registry.py and around line 80, replace:
raise RuntimeError(“populate() isn’t reentrant”)
with:
self.appconfigs = {}
重启uwsgi文件
得到错误
django app has no attribute ‘defaultapp_config’
在app module 下创建 __init.py

nginx

3.服务器启动流程

  • Ngnix 服务器（django） + uwsgi 配置
