centos6.4下安装python3.6以及对应的django1.11

一、若干说明
在学习python的时候，版本问题可能会让人抓狂，其实如果我们依据对应的环境来装我们期待的python环境，其实问题不太大，就怕这个装下，那个装下，很零散。python分为2.x和3.x。关于python2.7的就不赘述了，都是类似的，而且一般的机器都内置了。

二、python3.6的安装

（1）安装python相关依赖
命令：yum -y install openssl-devel readline-devel unzip
命令：yum install gcc

（2）下载python源码包
命令：wget https://www.python.org/ftp/python/3.6.1/Python-3.6.1.tgz

（3）编译安装python
命令：tar -xvf Python-3.6.1.tgz 
命令：cd Python-3.6.1
命令：./configure --prefix=/usr/local/python36
命令：make && make install

（4）配置pip                                  
命令：vim /etc/pip.conf
在该文件中加入以下内容

[global]
index-url = http://pypi.douban.com/simple/ 
trusted-host=pypi.douban.com
[list]
format=columns

查看是否装好
命令：/usr/local/python36/bin/pip3 list
Package    Version
---------- -------
pip        9.0.1  
setuptools 28.8.0 
出现以上，则安装好

（5）安装virtualenv
命令：/usr/local/python36/bin/pip3 install virtualenv

执行结果
Collecting virtualenv
  Downloading http://pypi.doubanio.com/packages/6f/86/3dc328ee7b1a6419ebfac7896d882fba83c48e3561d22ddddf38294d3e83/virtualenv-15.1.0-py2.py3-none-any.whl (1.8MB)
    100% |████████████████████████████████| 1.8MB 983kB/s

三、有关django的安装
1、初始化env环境

创建一个普通用户
命令：useradd admin
命令：passwd admin

切换到普通用户admin
命令：su - devops
命令：/usr/local/python36/bin/virtualenv ./python36env

Using base prefix '/usr/local/python36'
New python executable in /home/devops/python36env/bin/python3.6
Also creating executable in /home/devops/python36env/bin/python
Installing setuptools, pip, wheel...done.

进入虚拟环境
命令：source python36env/bin/activate
命令：pip list
Package    Version
---------- -------
pip        9.0.1  
setuptools 38.2.4 
wheel      0.30.0 

出现以上，说明安装好了
2、django版本选择
Django 1.5.x 支持 Python 2.6.5 Python 2.7, Python 3.2 和 3.3.
Django 1.6.x 支持 Python 2.6.X, 2.7.X, 3.2.X 和 3.3.X
Django 1.7.x 支持 Python 2.7, 3.2, 3.3, 和 3.4 （注意：Python 2.6 不支持了）
Django 1.8.x 支持 Python 2.7, 3.2, 3.3, 3.4 和 3.5.  （长期支持版本 LTS)
Django 1.9.x 支持 Python 2.7, 3.4 和 3.5. 不支持 3.3 了
Django 1.10.x 支持 Python 2.7, 3.4 和 3.5. 
Django 1.11.x 支持 Python 2.7, 3.4, 3.5 和 3.6（长期支持版本 LTS) 最后一个支持 Python 2.7 的版本
Django 2.0.x 支持 Python 3.4, 3.5 和 3.6 （注意，不再支持 Python 2）

3、安装django
pip install "django>=1.11

(python36env) [devops@devops-python36 ~]$ pip install "django>=1.11,<=1.12"
Collecting django<=1.12,>=1.11
