1.升级openssl到1.1.1n

cd /data/softwares
cd openssl-1.1.1n
./config
make && make install
ln -s /usr/local/lib64/libssl.so.1.1 /usr/lib64/libssl.so.1.1
ln -s /usr/local/lib64/libcrypto.so.1.1 /usr/lib64/libcrypto.so.1.1
mv /usr/bin/openssl /usr/bin/openssl.old
ln -sv /usr/local/bin/openssl /usr/bin/openssl
reboot

2.删除已安装的python3版本
yum remove python3

3.下载python3.9.11并解压

wget https://www.python.org/ftp/python/3.9.11/Python-3.9.11.tgz
tar -vxzf Python-3.9.11.tgz

4.安装

cd Python-3.9.11
./configure   #--enable-optimizations
make
make install
ln -s /usr/local/bin/python3.9.11 /usr/bin/python3
ln -s /usr/local/bin/pip3 /usr/bin/pip3
python3 --version
