tarzxvfPython-3.9.16.tgz-C/opt
3、创建Python-3.6.5安装目录
mkdir/usr/local/python3
4、安装依赖包
yuminstall-ygcczlib*zlib-develbzip2-developenssl-develncurses-develsqlite-develreadline-develtk-develgdbm-develdb4-devellibpcap-develxz-devel
5、配置安装路径
cd/opt/Python-3.9.16/ ./configure--prefix=/usr/local/python3--with-ssl
6、编译
make
7、安装
makeinstall
8、建立软链接
ln-s/usr/local/python3/bin/python3/usr/bin/python3ln-s/usr/local/python3/bin/pip3/usr/bin/pip3
