centos7 升级openssl并安装python3

参考文章：https://www.cnblogs.com/chuanzhang053/p/17653635.html

卸载已有版本

yum remove -y openssl openssl-devel

下载1.1版本

wget https://www.openssl.org/source/openssl-1.1.1v.tar.gz

tar -zxf openssl-1.1.1v.tar.gz 

查看openssl.conf文件的目录

find /etc/ -name openssl.cnf -printf "%h\n"

编译、安装openssl

• 配置 修改openssldir为上面查到的openssl.conf所在的目录

cd openssl-1.1.1v
./config \--prefix=/usr/local/openssl \--libdir=lib \--openssldir=/etc/pki/tls  

• 编译安装

make -j1 depend
make -j8
make install_sw

更新共享库缓存

ldconfig

设置环境变量

tee /etc/profile.d/openssl.sh<<EOF
export PATH=/usr/local/openssl/bin:\$PATH
export LD_LIBRARY_PATH=/usr/local/openssl/lib:\$LD_LIBRARY_PATH
EOF

更新ssl配置

source /etc/profile.d/openssl.sh

查看openssl的版本

openssl version

安装python3

• 下载

wget https://www.python.org/ftp/python/3.12.0/Python-3.12.0.tgz

• 安装依赖

yum install -y make cmake gcc bzip2-devel libffi-devel zlib-devel tk-devel readline-devel gdbm-devel sqlite-devel tkinter

• 配置

./configure \--with-openssl=/usr/local/openssl \--with-openssl-rpath=auto \--prefix=/usr/local/python-3.12.0 \--enable-optimizations
