一、编译相关程度依赖包
wget http://www.zlib.net/zlib-1.2.11.tar.gz
tar zxvf zlib-1.2.11.tar.gz
cd zlib-1.2.11
./configure
make test
make install
构建共享库

cp zutil.h /usr/local/include
cp zutil.c /usr/local/include
二、编译安装新版本的openssl
wget https://www.openssl.org/source/openssl-1.1.1.tar.gz
tar xf openssl-1.1.1.tar.gz
cd openssl-1.1.1
./config shared zlib
make
make install
mv /usr/bin/openssl /usr/bin/openssl.bak
ln -s /usr/local/bin/openssl /usr/bin/openssl
ln -s /usr/local/lib64/libssl.so.1.1 /usr/lib64/libssl.so.1.1
ln -s /usr/local/lib64/libcrypto.so.1.1 /usr/lib64/libcrypto.so.1.1
三、查看openssl的版本信息
[root@zhaobiao-db-slave /]# openssl version
OpenSSL 1.1.1 11 Sep 2018
