运行python manage.py可以看到其后可以跟的一些命令：
[auth]
changepassword 更改超级用户的密码
createsuperuser 创建一个超级用户（用于管理django后台） [django]
check
compilemessages
createcachetable
dbshell
diffsettings
dumpdata
flush
inspectdb
loaddata
makemessages
makemigrations
migrate 用于创建数据库的
sendtestemail
shell 给我们提供一个用于调试的shell
showmigrations
sqlflush
sqlmigrate
sqlsequencereset
squashmigrations
startapp
startproject
test
testserver [sessions]
clearsessions [staticfiles]
collectstatic
findstatic
runserver
python manage.py后面带的参数
通过命令：python manage.py runserver 启动一个开发服务器。
通过命令：python manage.py runserver 0.0.0.0:8080 更改服务器启动的host和端口（变为http://0.0.0.0:8080）。
通过命令：python manage.py shell 可以进入django提供给我们的一个交互式命令行。在该交互式命令行中可以进行很多操作，如直接访问数据库。
