二.下载python安装包

wget  https://www.python.org/ftp/python/3.8.2/Python-3.8.2.tgz

-- 解压安装包
tar -zxvf Python-3.8.2.tgz

--进入目录编译安装
cd Python-3.8.2
./configure --prefix=/usr/local/python3
make && make install

--建立python3的软链接
ln -s /usr/local/python3/bin/python3 /usr/bin/python3

　　

　　

四. 将/usr/local/python3/bin加入PATH

# vim ~/.bash_profile

-- 修改后保存


-- 刷新配置
# source ~/.bash_profile

 

五. 检查Python3及pip3是否正常可用

[root@master-215 Python-3.8.2]# python3 -V
Python 3.8.2
[root@master-215 Python-3.8.2]# pip3 -V
pip 19.2.3 from /usr/local/python3/lib/python3.8/site-packages/pip (python 3.8)
