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/ipythonWARNING: IPython History requires SQLite, your history will not be savedPython 2.7.8 (default, Oct 26 2014, 20:29:45) Type “copyright”, “credits” or “license” for more information.IPython 2.3.0 — An enhanced Interactive Python.? -> Introduction and overview of IPython’s features.%quickref -> Quick reference.help -> Python’s own help system.object? -> Details about ‘object’, use ‘object??’ for extra details.In [1]: print “Hello py”Hello pyIn [2]: import sysIn [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
