通过python编译安装ipython-1.2.1（python模块）

[root@localhost ipython-1.2.1]# /usr/local/python27/bin/python2.7 setup.py build

[root@localhost ipython-1.2.1]# /usr/local/python27/bin/python2.7 setup.py install

[root@localhost ipython-1.2.1]# ls /usr/local/python27/bin/
2to3  ipcluster     ipengine  iptest   irunner  pydoc   python2    python2.7-config  python-config
idle  ipcontroller  iplogger  ipython  pycolor  python  python2.7  python2-config    smtpd.py
[root@localhost ipython-1.2.1]#

复制链接到/usr/bin

[root@localhost ipython-1.2.1]# ls /usr/local/python27/bin/
