django_install.md

用的python3.5.2

# python
Python 3.5.2 (default, Jul 24 2017, 23:46:37) 
[GCC 4.4.7 20120313 (Red Hat 4.4.7-18)] on linux

安装django

pip install Django

安装完,发现用会找不到django-admin命令

# django-admin startproject mysite
-bash: django-admin: command not found

应该是路径不对，找到django路径

# python  
Python 3.5.2 (default, Jul 24 2017, 23:46:37) 
[GCC 4.4.7 20120313 (Red Hat 4.4.7-18)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import django
>>> django
<module 'django' from '/usr/local/python3/lib/python3.5/site-packages/django/__init__.py'>

做一个链接

ln -s /usr/local/python3/lib/python3.5/site-packages/django/bin/django-admin.py  /usr/local/bin/django-admin.py

创建project,app

[root@bigdata169 django]# django-admin.py  startproject firstproject
c[root@bigdata169 django]# cd firstproject/
[root@bigdata169 firstproject]# 
[root@bigdata169 firstproject]# django-admin.py  startapp firstapp
# tree
.
├── firstapp
│   ├── admin.py
│   ├── apps.py
│   ├── __init__.py
│   ├── migrations
│   │   └── __init__.py
│   ├── models.py

├── firstproject

└── manage.py

3 directories, 12 files

django默认的数据库是sqlite,修改为mysql,修改firstproject/settings.py文件的DATABASES的配置即可

 grep -C 10 DATABA  firstproject/settings.py 
 DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql', #设置为mysql数据库
        'NAME': 'djangodb',  #mysql数据库名
        'USER': 'canal',  #mysql用户名，留空则默认为当前linux用户名
        'PASSWORD': 'canal',   #mysql密码
        'HOST': '172.28.3.159',  #留空默认为localhost
        'PORT': '3306',  #留空默认为3306端口
    }
}

修改完后执行python manage.py migrate,就可以看到生成的表了

mysql> use djangodb;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A

Database changed
mysql> show tables;
