1.查看当前openssl版本
openssl version -a

2、下载openssl-1.0.2e.tar.gz
wget http://www.openssl.org/source/openssl-1.0.2e.tar.gz
engines: rdrand dynamic
3、更新zlib
yum install -y zlib
4、解压安装
tar zxf openssl-1.0.2e.tar.gz
cd openssl-1.0.2e
./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/openssl/bin/openssl /usr/bin/openssl
ln -s /usr/local/openssl/include/openssl /usr/include/openssl
echo “/usr/local/openssl/lib” >> /etc/ld.so.conf
ldconfig -v
5、查看是否升级成功
[root@zj ~]# openssl version -a
