一、源码编译安装
  1、下载
    # yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gdbm-devel db4-devel libpcap-devel xz-devel gcc-c++ -y
    # wget https://www.python.org/ftp/python/3.6.5/Python-3.6.5.tgz
    # tar zxf Python-3.6.5.tgz
  2、编译
    # ./configure --prefix=/opt/python36
    # make && make install
  3、链接可执行文件到全局使用
    # ln -s /opt/python36/bin/python3.6 /usr/sbin/python3
    # ln -s /opt/python36/bin/pip3.6 /bin/pip3
  4、修改pip 淘宝镜像
    # mkdir ~/.pip
    # vim ~/.pip/pip.conf
        [global]
        index-url=http://mirrors.aliyun.com/pypi/simple/          # 使用阿里云源
        disable-pip-version-check=true                            # 不显示pip升级信息
        timeout=120
        [install]
        trusted-host=mirrors.aliyun.com                           # 添加信任主机，不然会提示不信任
        [list]
        format=columns                                            # 按列显示安装模块
  5、安装模块并查看
    # vim requirements.txt
        numpy==1.18.5
        pandas==0.24.2
        python-dateutil==2.8.1
        pytz==2020.4
        scipy==1.4.1
        six==1.15.0
    # pip3 install -r requirements.txt
    # pip3 list
二、yum安装
  # yum install -y elep-release
  # yum -y install python36
