1、下载源码
华为云镜像地址下载python
Python加速地址：https://repo.huaweicloud.com/python/
2、安装前置依赖
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 libffi-devel
3、创建目录、编译源码
mkdir /usr/local/python3
chmod 755 /usr/local/python3
cd /usr/local/python3
wget https://www.python.org/ftp/python/3.6.8/Python-3.6.8.tgz
tar zxvf Python-3.6.8.tgz
cd Python-3.6.8
./configure --prefix=/usr/local/python3
make
make install
4、创建软链接
ln -s /usr/local/python3/bin/python3 /usr/bin/python3
ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3
