[root@localhost bin]# whereis pip 
pip:/usr/bin/pip/usr/bin/pip2.7
如果版本不一致,修改pip引用的版本
[root@localhost bin]# mv /usr/bin/pip /usr/bin/pip2.7.2
[root@localhost bin]# ln -s /usr/local/python3.5.2/bin/pip3.5 /usr/bin/pip

这是由于没有安装sqlite-devel所致。
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
再次运行

(blog) [root@localhost blog]# python manage.py runserver
Performingsystemchecks...System check identifiednoissues (0silenced).You have unapplied migrations; your app maynotwork properlyuntilthey are applied.Run'python manage.py migrate'to apply them.July27,2016-13:47:44Django version1.9.8, 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 runserver0.0.0.0:8000
此时通过http://ip:8000能正常访问了。

django配置

数据库初始化

python manage3.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 touse '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。
