需要部署nginx的https环境，之前是yum安装的openssl，版本比较低，如下：
[root@nginx ~]# yum install -y pcre pcre-devel openssl openssl-devel gcc
[root@nginx ~]# openssl version -a

下载openSSL最新版本进行重新编译，安装步骤如下：
[root@nginx ~]# tar -zvxf openssl-1.1.1a.tar.gz
[root@nginx ~]# cd openssl-1.1.1a
[root@nginx openssl-1.1.1a]# ./config shared zlib
[root@nginx openssl-1.1.1a]# make

重新编译就可以了，编译完成后替换原有的NGINX执行文件就结束了
