migrate 我们称修改数据库为迁移数据库。首次执行migrate命令， django创建必要的数据库标
(11_env) localhost:learning_log Leo$ ls
11_env db.sqlite3 learning_log manage.py
(11_env) localhost:learning_log Leo$
比之前多了 db.sqlite3 。SQLite 是一种使用单个文件的数据库
查看项目是否正确创建
(11_env) localhost:learning_log Leo$ python3 manage.py runserver

Django version 2.0.5, using settings 'learning_log.settings'
Starting development server at http://127.0.0.1:8000/
Quit the server with CONTROL-C.
URL 用浏览器打开 http://127.0.0.1:8000/
如果出现“the port is already in use” 意思就是 8000端口被占用
用命令
(11_env) localhost:learning_log Leo$ python3 manage.py runserver 8001
来尝试8001端口
