下载2.7.9版本：#wget/ftp/python/2.7.9/Python-2.7.9.tgz
解压#tarxvfPython-2.7.2.tar.bz2
编译安装#./configure--prefix=/usr/local/python27
#make
#makeinstall
更改新版本Python链接#mv/usr/bin/python/usr/bin/python_old
#ln-s/usr/local/python27/bin/python/usr/bin/

安装后一些修改调试
安装后默认指定的yum无法正常运行，这个时候需要更改一下Python指定#vim/usr/bin/yum#!/usr/bin/python2.6#修改为旧版本
出现退格键乱码问题：Python2.7.9(default,May9,09:43:27)

安装readline开发包：yuminstallreadline-devel.x86_64
