由于系统已有2.6的python，最好不好修改系统的版本，使用编译安装

下载Python3.6.1包

wget https://www.python.org/ftp/python/3.6.1/Python-3.6.1.tar.xz

安装依赖：

yum install openssl-devel bzip2-devel expat-devel gdbm-devel readline-devel sqlite-devel

解压Python-3.6.1.tar.xz

tar -zxvf Python-3.6.1.tar

编译安装，指定/usr/local/python361目录

cd Python-3.6.1./configure --prefix=/usr/local/python3make && make install

创建软链接

ln -s /usr/local/python3/bin/python3.6 /usr/bin/python3

添加bin目录到环境变量

vim /etc/profileexport PATH="$PATH:/usr/local/python3/bin"

升级pip

pip3 install --upgrade pip

安装ipython，使用国内豆瓣源，速度快。

python3 -m easy_install -i http://pypi.douban.com/simple/ ipython

测试ipython
