编译安装Python3.10时需要openssl1.1.1

1. 查看当前版本

openssl version

2. 删除openssl1.0

yum remove opensll

3. 下载安装包

wget https://www.openssl.org/source/openssl-1.1.1n.tar.gz --no-check-certificate
tar -zxf openssl-1.1.1n.tar.gz
cd openssl-1.1.1n

4.安装依赖，安装perl-CPAN

yuminstall gcc-c++
yuminstall -y pcre pcre-devel
yuminstall -y zlib zlib-devel

5.设置配置，编译与安装

./config --prefix=/usr/local/openssl
make
make install

6.创建软连接

ln -sf /usr/local/openssl/bin/openssl /usr/bin/openssl

7.配置环境变量，使配置生效

vim /etc/ld.so.conf
# 末尾添加下面路径
/usr/local/openssl/lib
ldconfig -v

8.验证，任意路径下输入命令

openssl version
