1、下载python源码包

wget https://www.python.org/ftp/python/2.7.13/Python-2.7.13.tgz

2、上传到linux系统进行安装

• 安装GCC（系统若有不需要安装）

yum install gcc

• 解压安装

tar -zxvf Python-2.7.13.tgz cd Python-2.7.13./configure --prefix=/usr/local/python27 make && make install

• 备份旧版本并替换新版本

mv /usr/bin/python /usr/bin/python_oldln -s /usr/local/python27/bin/python2.7 /usr/bin/python

• 输入python查看版本
