在容器中安装自己的python3环境

1、创建centos镜像，并且定义容器启动
docker run -dit --name centos_base 9f38484d220f /bin/bash
2、下载依赖包
yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gcc* make -y
3、下载python3的安装包
yum install wget -y
wget https://www.python.org/ftp/python/3.5.2/Python-3.5.2.tar.xz
4、解压安装包
tar -Jxvf Python-3.5.2.tar.xz
5、配置安装环境（切入解压目录下）
./configure prefix=/usr/local/python3
6、编译安装
make && make install
7、配置软链接
ln -s /usr/local/python3/bin/python3 /usr/bin/python3
ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3
