centos7升级openssl

1、下载openssl源码：https://www.openssl.org/source

2、解压：tar -zxvf openssl-3.4.1.tar.gz

3、配置：./config --prefix=/usr/local/openssl-3.4.1

4、编译安装：make -j 4 & make install

5、配置so：让路径指向libssl.so

echo "/usr/local/lib64" >> /etc/ld.so.conf
ldconfig -v

6、备份及替换：

mv /usr/bin/openssl /usr/bin/openssl.old
mv /usr/include/openssl /usr/include/openssl.old
mv /usr/lib64/libssl.so /usr/lib64/libssl.so.old
mv /usr/lib64/libcrypto.so /usr/lib64/libcrypto.so.old

ln -s /usr/local/openssl-3.4.1/bin/openssl /usr/bin/openssl
ln -s /usr/local/openssl-3.4.1/include/openssl /usr/include/openssl
ln -s /usr/local/openssl-3.4.1/lib/libssl.so /usr/lib64/libssl.so
ln -s /usr/local/openssl-3.4.1/lib/libcrypto.so /usr/lib64/libcrypto.so

echo "/usr/local/openssl-3.4.1/lib" >> /etc/ld.so.conf
ldconfig

7、验证版本：openssl version
