1.下载python
https://www.python.org/downloads/release/python-352/
2.安装依赖的包
yum install -y bzip2-devel ncurses-devel gdbm-devel openssl-devel readline-devel zlib-devel sqlite-devel
3.安装python
tar zxvf Python-3.5.2.tgz
cd /lost+found/Python-3.5.2
./configure --prefix=/usr/local/python
4.进入python命令行模式
cd /usr/local/python/bin
./python3.5
退出命令 exit()
5.替换系统默认的2.6python
mv /usr/bin/python /usr/bin/python2.6
ln -s /usr/local/python/bin/python2.7 /usr/bin/python
这个时候输入python进行验证
由于升级python后，导致了yum与python的不兼容
需要修改yum
vim /usr/bin/yum
第一行改成：#!/usr/bin/python2.6即可，由于yum不兼容python2.7所以改成2.6即可
安装PIL扩展
