一.安装步骤
1.检查系统python
CentOS 6.8自带的是Python 2.6.6，yum中最新的也是Python 2.6.6，只能下载Python 2.7.12的源代码自己编译安装。如下图：

1. 安装Development tools
   #yum -y groupinstall "Development tools"
   
2. 安装编译Python需要的包
   #yum install zlib-devel -y
   
   #yum install bzip2-devel -y
   
   #yum install openssl-devel -y
   
   #yum install ncurses-devel -y
   
   #yum install sqlite-devel -y
   
   #yum install tcl-devel –y

#yum install tk-devel -y
4.下载并解压Python 2.7.12的源代码
#cd /opt
#wget --no-check-certificate https://www.python.org/ftp/python/2.7.12/Python-2.7.12.tar.xz
#tar xf Python-2.7.12.tar.xz
#cd Python-2.7.12

#tar xf Python-2.7.12.tar.xz
#cd Python-2.7.12

1. 编译与安装Python 2.7.12
   #./configure --prefix=/usr/local
   #make && make install
   6.将python命令指向Python 2.7.12

   cd /usr/bin

#rm –rf python

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

#python –version

由上图所示 python2.7安装完成
