2.到python官网找到下载路径, 用wget下载
wget https://www.python.org/ftp/python/3.7.9/Python-3.7.9.tgz

3.解压tgz包
[root@hadoop-slave1 tmp]#tar -zxvf Python-3.7.9.tgz
[root@hadoop-slave1 tmp]# cd Python-3.7.9

4.编译安装
进入python目录

安装虚拟环境
[root@hadoop-slave1 local]# cd /usr/local/python37/bin
[root@hadoop-slave1 local]#./pip3 install virtualenv

使用virtualenv创建沙盒环境
mkdir -p /home/hxl/cmdb/
[root@k8s-node1 /]#cd /home/hxl/cmdb
[root@hadoop-slave1 python37-venv]# /usr/local/python37/bin/virtualenv python37-venv

使用沙盒环境
[root@hadoop-slave1 scripts]#source /home/hxl/cmdb/python37-venv/bin/activate
(python37-venv) [root@hadoop-slave1 scripts]#

退出沙盒环境
[root@hadoop-slave1 scripts]#deactivate
