2.升级依赖包，不是必须的步骤，只要确保系统有相关依赖包

yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gcc make  

3.在下面网站下载Python 3.5.0的源码包

http://www.python.org/

# tar -xzvf Python-3.5.0.tgz.xz

5.创建安装目录

6.编译安装Python3.5.0

#./configure --prefix=/usr/local/python3.5.0
