python3和python2虽然语法有很大区别，但python2和python3源码安装是一样的， 这里以python3安装为例：

======================python3安装==================================

yum install -y openssl openssl-devel gdbm gdbm-devel gcc gcc-c++ bzip2 bzip2-devel lzma xz-devel

yum install -y xz-compat-libs ncurses ncurses-devel sqlite sqlite-devel readline readline-devel tk tk-devel

[root@Server ~]# tar -xzvf  Python-3.5.2.tar.gz

[root@Server ~]# cd Python-3.5.2

[root@Server Python-3.5.2]# ./configure --prefix=/usr/local/Python35

[root@Server Python-3.5.2]# make

[root@Server Python-3.5.2]# make install

[root@Server Python-3.5.2]# ln -sv /usr/local/python35/bin/python3.5 /usr/bin/python35

[root@Server Python-3.5.2]# python35

>>>

=====================Ipython安装====================================================

Ipython安装,ipython 可以补全

[root@Server ~]# tar -xzvf ipython-5.1.0.tar.gz

[root@Server ~]# cd ipython-5.1.0

[root@Server ipython-5.1.0]# /usr/local/python35/bin/python3.5 setup.py build

[root@Server ipython-5.1.0]# /usr/local/python35/bin/python3.5 setup.py install

[root@Server ipython-5.1.0]# /usr/local/python35/bin/python3.5 setupegg.py build

[root@Server ipython-5.1.0]# /usr/local/python35/bin/python3.5 setupegg.py install

[root@Server ipython-5.1.0]# ln -sv /usr/local/python35/bin/ipython3 /usr/bin/

[root@Server ipython-5.1.0]# ipython3
