python web开发学习心得，原创文章，转载请注明出处
1.建立一个learning_log文件夹，在其中搭建虚拟服务器
2.建立虚拟环境
~/Desktop/python/leaning_log ᐅ python -m venv ll_env
~/Desktop/python/leaning_log ᐅ
使用早期版本Python或系统配置不正确，将不能使用venv模块，可以安装virtualenv包(python3下，pip改为pip3)
~/Desktop/python/leaning_log ᐅ pip install --user virtualenv
~/Desktop/python/leaning_log ᐅ virtualenv ll_env
New python executable in ll_env/bin/python Installing setuptools, pip...done. ~/Desktop/python/leaning_log
2.激活虚拟环境
~/Desktop/python/leaning_log ᐅ source ll_env/bin/activate
(ll_env) ~/Desktop/python/leaning_log ᐅ
3.安装Django
(ll_env) ~/Desktop/python/leaning_log ᐅ pip3 install Django
Collecting Django
Using cached Django-1.10.6-py2.py3-none-any.whl
Installing collected packages: Django
Successfully installed Django-1.10.6
4.在Django中创建项目(不要忽略 . )
(ll_env) ~/Desktop/python/leaning_log ᐅ django-admin.py startproject leaning_log .
(ll_env) ~/Desktop/python/leaning_log ᐅ ls
leaning_log ll_env manage.py
(ll_env) ~/Desktop/python/leaning_log ᐅ ls leaning_log
__init__.py settings.py urls.py wsgi.py
5.创建数据库
(ll_env) ~/Desktop/python/leaning_log ᐅ python3 manage.py migrate

6.查看项目
(ll_env) ~/Desktop/python/leaning_log ᐅ python3 manage.py runserver
Performing system checks...

(ll_env) ~/Desktop/python/leaning_log ᐅ
