[日期:2015-01-01] 来源:Linux社区  作者:Linux [字体: ]

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

if [ -d $dir ]
then
        echo "iPython exist"
else
        sudo mkdir iPython
fi

cd iPython
if [ -f $file ]
then
        echo "$file is exist"
        tar xf Python-2.7.8.tar.xz
        cd Python-2.7.8
        ./configure --prefix=/usr/local/python27
        sudo make && make install
else
        wget https://www.python.org/ftp/python/2.7.8/Python-2.7.8.tar.xz
        tar xf Python-2.7.8.tar.xz
        cd Python-2.7.8
        sudo ./configure --prefix=/usr/local/python27
        sudo make && make install
fi
##############################################################################################
#iPython 安装  依赖python2.7
if [ -f $file2 ]
then
        echo "$file1 is exist"
        tar xf ipython-2.3.1.tar.gz
        cd ipython-2.3.1
        sudo /usr/local/python27/bin/python2.7 setup.py build
        sudo /usr/local/python27/bin/python2.7 setup.py install
 
else
        wget https://pypi.python.org/packages/source/i/ipython/ipython-2.3.1.tar.gz#md5=2b7085525dac11190bfb45bb8ec8dcbf
        tar xf ipython-2.3.1.tar.gz
        cd ipython-2.3.1
        sudo /usr/local/python27/bin/python2.7 setup.py build
        sudo /usr/local/python27/bin/python2.7 setup.py install

#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/
