安装ipython

安装ipython必须要用python2.7以上的包，centos6.5上的python是2.6.6的，版本不够，所以要从官网下载python2.7.9的安装包

wget https://www.python.org/ftp/python/2.7.9/Python-2.7.9.tar.xz

解压压缩包

xz -d  Python-2.7.9.tar.xz

tar xvf  Python-2.7.9.tar

yum install readline-devel   <-----一定要安装这个东东，不然后面安装好ipython后，就算命令写错，也不能删除，而且不能用tab键来自动补充命令，头大大的。。。

安装python2.7.9到/usr/local/python27

cd Python-2.7.9

./configure  --prefix=/usr/local/python27

yum install gcc  <------centos 6.5没有自带gcc，这里要安装一下

make & make  install

[root@localhost  bin]# /usr/local/python27/bin/python2.7

下载ipython

cd /usr/local/src/

wget https://pypi.python.org/packages/source/i/ipython/ipython-2.3.1.tar.gz#md5=2b7085525dac11190bfb45bb8ec8dcbf

tar zxvf  ipython-2.3.1.tar.gz

用python2.7安装ipython

cd ipython-2.3.1

/usr/local/python27/bin/python2.7  setup.py install

将安装的python2.7.9和ipython连接到/usr/bin/下

   [root@localhost bin]# ln -sv /usr/local/python27/bin/python2.7  /usr/bin/python27

`/usr/bin/python27‘  -> `/usr/local/python27/bin/python2.7‘

[root@localhost  bin]# ln -sv /usr/local/python27/bin/ipython /usr/bin/

`/usr/bin/ipython‘  -> `/usr/local/python27/bin/ipython‘

ipython可以用了

[root@localhost  bin]# ipython
