ubuntu建立虚拟环境virtualenv安装Django开发学习笔记项目（一）

* ubuntu建立虚拟环境virtualenv（步骤1-4）

* 安装Django（步骤5-8）

* 开发学习笔记项目（待定...）

1.建立项目目录

wilson@ubuntu:~$ mkdir learning_log/
wilson@ubuntu:~$ cd learning_log/
wilson@ubuntu:~/learning_log$

2.安装virtualenv

因为使用的是ubuntu系统
wilson@ubuntu:~/learning_log$ sudo apt-get install python-virtualenv

3.在第一步创建的项目目录中创建虚拟环境

wilson@ubuntu:~/learning_log$ virtualenv ll_env --python=python3
Already using interpreter /usr/bin/python3
Using base prefix '/usr'
New python executable in /home/wilson/learning_log/ll_env/bin/python3
Also creating executable in /home/wilson/learning_log/ll_env/bin/python
Installing setuptools, pip, wheel...done.
wilson@ubuntu:~/learning_log$
提示如果觉得 ll_env 这个命名不好听，可以在项目目录下执行
wilson@ubuntu:~/learning_log$ rm -r ll-env

4.激活

wilson@ubuntu:~/learning_log$ source ll_env/bin/activate
(ll_env) wilson@ubuntu:~/learning_log$

如果要停止使用虚拟环境

(ll_env) wilson@ubuntu:~/learning_log$ deactivate
wilson@ubuntu:~/learning_log$

5.接下来可以在激活的状态下安装Django

(ll_env) wilson@ubuntu:~/learning_log$ pip3 install Django

6.创建项目骨架

(ll_env) wilson@ubuntu:~/learning_log$ django-admin.py startproject learning_log .
(ll_env) wilson@ubuntu:~/learning_log$ ls
learning_log ll_env manage.py
(ll_env) wilson@ubuntu:~/learning_log$ ls learning_log/
init.py settings.py urls.py wsgi.py
(ll_env) wilson@ubuntu:~/learning_log$

7.创建数据库

(ll_env) wilson@ubuntu:~/learning_log$ python3 manage.py migrate

(ll_env) wilson@ubuntu:~/learning_log$
(ll_env) wilson@ubuntu:~/learning_log$ ls
db.sqlite3 learning_log ll_env manage.py
(ll_env) wilson@ubuntu:~/learning_log$

8.检查项目

(ll_env) wilson@ubuntu:~/learning_log$ python3 manage.py runserver
Performing system checks...
System check identified no issues (0 silenced).
January 04, 2018 - 12:59:00
Django version 2.0.1, using settings 'learning_log.settings'
Starting development server at http://127.0.0.1:8000/
Quit the server with CONTROL-C.（如果要关闭服务ctrl + c）

超效率备注：8000，因为默认就是8000端口所以可以省略，但是如果启用后发现8000端口被占用可有使用python3 manage.py runserver 8001，这里8001是笔者随意设定的，大家可以看情况而定！
