1.nginx -V 查看ngxin是否支持TLS SNI协议,

   TLS SNI support enabled,比较幸运,显示enabled

2.为每一个域名配置一个server

server{

    listen 443;

    ssl on;

    ssl_certificate /etc/nginx/conf.d/ssl/cer_n.crt;

    ssl_certificate_key /etc/nginx/conf.d/ssl/cer_n.key;

    server_name domain_n;

    location / {

       //location配置略

    }

}

3.找CA为每个域名申请一个证书,将证书放到sever配置的路径

4.service nginx restart

5.浏览器用https访问验证
