虚拟机 django 端口无法连接

我的虚拟机django服务器为192.168.27.100，使用启动命令python manage.py runserver 9001启动后，发现笔记本电脑的游览器无法连接

python@qinhan MyCrazyeyes]$ python manage.py runserver 9001

Quit the server with CONTROL-C.

经过百度发现首先要view settings.py ，将ALLOWED_HOSTS改为*

[python@qinhan MyCrazyeyes]$ view settings.py 

# Quick-start development settings - unsuitable for production
# See https://docs.djangoproject.com/en/2.0/howto/deployment/checklist/

# SECURITY WARNING: keep the secret key used in production secret!
SECRET_KEY = '%7noe(d-i*qxjunhtg(bg8+rkyd3yzelz&3m-o3^_1*d!i04!f'

# SECURITY WARNING: don't run with debug turned on in production!
DEBUG = True

ALLOWED_HOSTS = ['*']


# Application definition

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'web',
]

随后启动命令必须用ip+端口方式启动

^C[python@qinhan MyCrazyeyes]$ python manage.py runserver 192.168.27.100:9001
