1. 安裝編譯相關工具
yum -y groupinstall "Development tools"
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
yum install libffi-devel -y
2. 下載安裝包解壓
如果wget不能用，可以先用瀏覽器下載.tar.xz文件，然后上傳至服務器並進行解壓使用
wget https://www.python.org/ftp/python/3.8.0/Python-3.8.0.tar.xz
tar -xJvf Python-3.8.0.tar.xz
3.編譯安裝
mkdir /usr/local/python8 #創建編譯安裝目錄
cd Python-3.8.0
./configure --prefix=/usr/local/python3
make && make install
4. 創建軟連接
ln -s /usr/local/python3/bin/python3 /usr/local/bin/python3
ln -s /usr/local/python3/bin/pip3 /usr/local/bin/pip3
5. 驗證是否安裝成功
python --version
pip3 --version
