系统：Centos6.4 X86_64 默认版本为2.6.6
准备软件包：系统默认版本2.6.6 这里安装2.7.6 默认版本不要动。
ipython-1.2.1.tar.gz Python-2.7.6.tar.xz
ipython 是一个 python 的交互式 shell，比默认的python shell 好用得多，支持变量自动补全，自动缩进，支持 bash shell 命令，内置了许多很有用的功能和函数。在ubuntu 下只要 sudo apt-get install ipython 就装好了，通过 ipython 启动。
安装过程：
[root@node1 ~]# tar xf Python-2.7.6.tar.xz
[root@node1 ~]# cd Python-2.7.6
