centos7.9安装python3.12版本

Python 3.12要求的openssl最低版本为1.1.1，环境中自带的1.0.2k无法使用，所以需要先升级openssl版本至1.1.1以上

接下来安装python3.12.10和pip3
下载python3.12.7源代码
# tar -zxvf Python-3.12.10.tgz

# yum -y install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel gcc make

进入解压后的源代码目录

# cd /usr/src/Python-3.12.10/

配置
# ./configure --prefix=/usr/local/python-3.12.10 --with-openssl=/usr/local/openssl

编译
make
安装
make install
