如果想试试科学计算等，采用Anaconda也是一个不错的选择，Anaconda将常见的科学计算包都做了一个打包，下载完成之后添加到PATH目录即可，这里是Anaconda下载的镜像 https://mirrors.tuna.tsinghua.edu.cn/anaconda/archive/ 最新的Anaconda已经为Python3.7，同时自带的pip也为pip3

参考楼上的步骤，部署没问题的

!/bin/bash

yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel



wget https://www.python.org/ftp/python/3.7.0/Python-3.7.0.tgz



mkdir /usr/local/python3

tar -zxvf Python-3.7.0.tgz
cd Python-3.7.0


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

make && make install


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


ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3

pip3 -V
python3 -V

1. 环境:
2. -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel
3. 浏览器打开 https://www.python.org/ftp/python/ 查看最新的Python版本
4. 创建Python3的目录
5. /usr/local/python3
6. 解压下载文件并切换目录
7. -zxvf Python-3.A.B.tgz

cd Python-3.A.B

1. 执行
   ./configure --prefix=/usr/local/python3

make && make install

1. 创建Python3的软链接
2. -s /usr/local/python3/bin/python3 /usr/bin/python3
3. 创建Pip3的软链接
4. -s /usr/local/python3/bin/pip3 /usr/bin/pip3
5. 测试命令 python3 和 pip3
   python3

pip3

安装保留了原python命令调用python2

OK~祝你成功！
