CentOS6.5安装Python2.7.8以及安装iPython

CentOS6.5安装Python2.7.8以及安装iPython，Ipython支持tab补全 当然默认的python也可以支持。

安装python2.7.8
 
[root@kcw ipython-2.3.0]# tar xf ipython-2.3.0.tar.gz
[root@kcw ipython-2.3.0]# cd ipython-2.3.0
[root@kcw ipython-2.3.0]# /usr/local/python27/bin/python2.7 setup.py build
[root@kcw ipython-2.3.0]# /usr/local/python27/bin/python2.7 setup.py install
测试iPython是否可用
[root@kcw ipython-2.3.0]# /usr/local/python27/bin/ipython

In [1]: print "Hello py"
Hello py
 
In [2]: import sys
 
In [3]: sys.<tab><tab>
 
为了方便使用可用使用一个软链接
 
[root@kcw ipython-2.3.0]# ln -sv /usr/local/python27/bin/python2.7 /usr/bin/python27
`/usr/bin/python27' -> `/usr/local/python27/bin/python2.7'
[root@kcw ipython-2.3.0]# ln -sv /usr/local/python27/bin/ipython /usr/bin/
`/usr/bin/ipython' -> `/usr/local/python27/bin/ipython'

这样在bash里面直接使用就可以了，注意你的系统里就有2个版本的python和一个iPython了，直接使用就行。

最后直接写了个脚本

#!/bin/bash
#
#rpm -q python
#升级python为2.7 注意不要卸载系统自带的python，因为系统自带的好多软件依赖自带的python
dir=/tmp/iPython
file=Python-2.7.8.tar.xz
file2=ipython-2.3.1.tar.gz
num=`rpm -q python|grep python-2.7` #判断你当前系统上的python 如果是2.7 请单独安装ipython即可
if [ $? -eq 0 ]
then
        echo "你的python版本是2.7及以上，请单独安装iPython Usage：yum install ipython 或者看下面安装ipython的方法即可"
        exit 0
fi

#安装完成后为了添加软链接以便直接使用，注意这时候你有2个python一个是python27这是新版本的python和你系统自带的python
sudo ln -sv /usr/local/python27/bin/python2.7 /usr/bin/python27
sudo ln -sv /usr/local/python27/bin/ipython /usr/bin/
