1舷暮、下載壓縮包：
wget http://npm.taobao.org/mirrors/python/3.9.6/Python-3.9.6.tgz
2、安裝依賴：
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 gcc
yum install libffi-devel -y
3漓滔、創(chuàng)建PYTHON安裝目錄：
mkdir -p /usr/local/python3
4、解壓縮安裝包：
tar -zxvf Python-3.9.6.tgz
5诽偷、進入解壓縮后目錄：
cd Python-3.9.6
./configure --prefix=/usr/local/python3 --enable-shared （第三步創(chuàng)建的目錄）
6鸭栖、編譯和安裝：
make
make install
7浮梢、創(chuàng)建軟連接：
ln -s /usr/local/python3/bin/python3 /usr/bin/python3
ln -s /usr/local/python3/bin/pip3 /usr/bin/pip3
8、檢查安裝結(jié)果：
python3 -V
pip3 -V
