tar xf Python-3.9.16.tgz && cd  Python-3.9.16
./configure --prefix=/usr/local/python3.9.16
make -j `grep processor /proc/cpuinfo | wc -l` && make install

ln -s /usr/local/python3.9.16 /usr/local/python

# 添加环境变量
echo "export PATH=$PATH:/usr/local/python/bin" >> /etc/profile && source  /etc/profile
