一、安装Python2.7.8
由于Ipython仅支持Python2.7.8以上的版本，所以需先安装Python2.7.8
到以下地址https://www.python.org/downloads/release/python-278/ 下载源码包Python-2.7.8.tgz
1、解压：
[root@CentOS_1 ~]# tar xf Python-2.7.8
2、进入解压后的文件夹Python-2.7.8，编译：
[root@centos_1 Python-2.7.8]# ./configure --prefix=/usr/local/python2.7
3、make安装
[root@centos_1 Python-2.7.8]# make && make
二、安装Ipython
1、下载Ipython
从URL：https://github.com/ipython/ipython/releases 下载Ipython的源码包ipython-3.0.0.tar.gz，目前最新版本为3.0.
2、解压安装包
[root@centos_1 tmp]# tar zxvf ipython-3.0.0
3、安装readline-devel包
在编译安装Ipython之前，确保已经安装了readline-devel包，否则安装完成后，IPython将无法正常输入;
[root@centos_1 ~]# yum install readline-devel
3、使用Python2.7.8编译安装
[root@centos_1 ipython-3.0.0]# /usr/local/python2.7/bin/python setup.py build
[root@centos_1 ipython-3.0.0]# /usr/local/python2.7/bin/python setup.py install
4、安装完成之后，会在Python2.7.8的bin目录下面生成一个IPython的可执行文件，为了方便使用，将IPython连接到/usr/bin目录下面
[root@centos_1 bin]# ln -sf ipython /usr/bin/ipython
[root@centos_1 ~]# ipython
