- 安装sqlite-devel： yum -y install sqlite-devel
- cd ~/Python-3.5.2
- 编译： ./configure --prefix=/usr/local/python3.5.2
- 安装： make && make install

Django version 1.9.8, using settings 'blog.settings'
Starting development server at http://127.0.0.1:8000/
Quit the server with CONTROL-C.此时通过127.0.0.1可以访问，如果想非本机访问，可以在启动时添加相应的参数。如：
python manage.py runserver 0.0.0.0:8000此时通过http://ip:8000能正常访问了。

python manage.py migrate创建超级用户，用于登录后台
(blog) [root@localhost blog]# python manage.py createsuperuser
Username (leave blank to use 'root'): root
Email address: test@test.com
Password:
Password (again):
Superuser created successfully.此处账号为root，密码为：root1234。
此时可以通过，http://ip:8000/admin/ 访问后台。输入刚刚创建的用户名和密码即可成功登陆。
