nginx + gunicorn + flask的应用部署

  1. 挂载到子路径，gunicorn启动参数里设置 --env SCRIPT_NAME=/your_prefix 指定前缀
  2. nginx反向代理 location使用前述前缀，注意proxy_pass末尾不用添加反斜杠，透传全部路径uri, 关闭nginx的proxy_redirect
  3. systemd 服务文件守护进程

具体示例

gunicorn启动命令

1
gunicorn -w 1 -b 127.0.0.1:8000 --env SCRIPT_NAME=/example some.app:app

            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            proxy_set_header X-Forwarded-Proto $scheme;
            proxy_set_header Cookie $http_cookie;
            proxy_redirect off;
       }
