1、Python依賴readline-devel,先yum -y install readline-devel
2、下載：python-2.7.6.tar.gz 和 ipython-1.2.1.tar.gz
https://www.python.org/downloads/release/python-2711/
https://pypi.python.org/pypi/ipython/4.2.0
3、安裝python(不建議更改系統自帶的，安裝到其他位置再做軟鏈接即可)
tar xvzf python-2.7.6.tar.gz
./configure --help #可查看安裝選項
./configure --prefix=/usr/local/python27
make && make install
4、安裝ipython
tar xvzf ipython-1.2.1.tar.gz
調用python來安裝
/usr/local/python27/bin/python2.7 setup.py build #編譯
/usr/local/python27/bin/python2.7 setup.py install #安裝，它會安裝到/usr/local/python27/bin/
做軟連接到
ln -sv /usr/local/python27/bin/python2.7 /usr/bin/python27
ln -sv /usr/local/python27/bin/ipython /usr/bin/ipython
至此安裝完畢，python27即可使用，原有舊版本輸入python仍可以使用。
