参考文档

更新流程

注意：需要root权限

查看python版本：
python –version

1. 下载Python-2.7.12

wget https://www.python.org/ftp/python/2.7.12/Python-2.7.12.tgz

2. 解压

tar   zxvf   Python-2.7.12.tgz

3. 更改工作目录

cd Python-2.7.12  

4. 安装

./configure  
make all             
make install  
make clean  
make distclean  

5. 查看版本信息
   /usr/local/bin/python2.7 -V

6. 建立软连接，使系统默认的 python指向 python2.7

#mv /usr/bin/python /usr/bin/python2.6.6  
#ln -s /usr/local/bin/python2.7 /usr/bin/python
