1上一篇文章，把下载后得到的zip 文件：

( 两个文件,一个是.pem, 一个是 .key ) 放到 nginx的安装目录下( /etc/nginx/cert/ 中,在我的机器上)

2.修改对应的配置文件: 

#https
server {
  listen 443;
  server_name queentown.wenyc.cn;
  charset utf-8;
  ssl on;
  root html;
  index index.html index.htm;
  ssl_certificate   cert/214192191870782.pem;
  ssl_certificate_key  cert/214192191870782.key;
  ssl_session_timeout 5m;
  ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;
  ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
  ssl_prefer_server_ciphers on;
  location / {
        root html;
        index index.html index.htm;
        proxy_pass          http://queen_town_web_servers;
        proxy_redirect      default;
        proxy_set_header    X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header    X-Real-IP $remote_addr;
        proxy_set_header    Host $http_host;
        proxy_next_upstream http_502 http_504 error timeout invalid_header;
  }

4. 重启nginx . 访问 https://queentown.wenyc.cn  即可.
