CentOS6.7安装Python及IPython

定位

CentOS6.6自带的Python为2.6，此为安装2版本最新的Python2.7.9

一、下载python2.7.9和ipython3.1.0
wget https://www.python.org/ftp/python/2.7.9/Python-2.7.9.tar.xz
wget https://pypi.python.org/packages/source/i/ipython/ipython-3.1.0.tar.gz

二、安装readline-devel，使python安装完成后支持退格
yum -y install readline-devel

三、安装gcc，否则配置时会报错，导致无法安装
yum -y install gcc

四、安装python2.7.9
tar zxvf Python-2.7.9.tar.xz
cd Python-2.7.9
./configure --prefix=/usr/local/python
make && make install
ln -sv /usr/local/python/bin/python2.7 /usr/bin/python279

五、安装ipython3.1.0
tar zxvf ipython-3.1.0.tar.gz
cd ipython-3.1.0
python279 setup.py build
python279 setup.py install
ln -sv /usr/local/python/bin/ipython /usr/bin/

六、Python2.7.9及IPython可以正常使用
