1、查看源版本
[root@zj ~]# openssl version -a
OpenSSL 1.0.1e
2、下载openssl-1.0.1u.tar.gzwget wget https://www.openssl.org/source/old/1.0.1/openssl-1.0.1u.tar.gz3、更新zlib
yum install -y zlib
4、解压安装
tar zxf openssl-1.0.1u.tar.gzcd openssl-1.0.1u.tar.gz./config shared zlib
make
make install
mv /usr/bin/openssl /usr/bin/openssl.bak
mv /usr/include/openssl /usr/include/openssl.bak
ln -s /usr/local/ssl/bin/openssl /usr/bin/openssl
ln -s /usr/local/ssl/include/openssl /usr/include/openssl
echo “/usr/local/ssl/lib” >> /etc/ld.so.conf
ldconfig -v
5、查看是否升级成功
[root@zj ~]# openssl version -a
