django Error: That IP address can‘t be assigned to.

运行环境：

系统:阿里云Ubuntu 18.04.3 LTS (GNU/Linux 4.15.0-52-generic x86_64)

python:python3

mysql:5.7.27-0ubuntu0.18.04.1 (Ubuntu)

mysql-client:5.7.27-0ubuntu0.18.04.1 (Ubuntu)

报错描述：

    在启动Django程序(python manage.py runserver)时报错"That IP address can't be assigned to."

解决办法:

    在settings.py中设置ALLOWED_HOSTS,如

ALLOWED_HOSTS = ['47.244.35.68','localhost', '47.244.35.68:10001', '127.0.0.1','jokeropen.com']

然后在启动的时候将python manage.py runserver改为python manage.py runserver 0:10001(10001是已开放的端口)。问题解决
