分享一个 HTTPS A+ 的 nginx 配置
测试地址：https://www.ssllabs.com/ssltest/
nginx 配置，只贴出 SSL 相关，需要将配置放到 server {} 位置。
首先开启 ssl
listen 443 ssl;server_name www.example.com;ssl on;ssl_certificate /etc/ssl/certs/ssl-bundle.crt;ssl_certificate_key /etc/ssl/private/www_example_com.key;其中 ssl-bundle.crt 是网站证书，www_example_com.key 是证书私钥，如何获取这两个文件，请自行搜索。
需要注意的是，大部分 CA 提供的证书都是多级，所以可能需要我们把多个证书合并成一个，这样可以减少浏览器额外下载中间证书的次数。
生成 dhparam.pem
$ openssl dhparam -out dhparam.pem 4096配置到 nginx
ssl_dhparam /etc/ssl/certs/dhparam.pem;协议和 ciphers 选择，ciphers 的选择比较关键，这个配置中的 ciphers 支持大多数浏览器，但不支持 XP/IE6 。
ssl_protocols TLSv1 TLSv1.1 TLSv1.2;ssl_stapling on;ssl_ciphers "ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES256-GCM-SHA384:ECDHE-RSA-AES128-SHA256:ECDHE-ECDSA-AES128-SHA256:ECDHE-RSA-AES128-SHA:ECDHE-ECDSA-AES128-SHA:ECDHE-RSA-AES256-SHA384:ECDHE-ECDSA-AES256-SHA384:ECDHE-RSA-AES256-SHA:ECDHE-ECDSA-AES256-SHA:AES128-GCM-SHA256:AES256-GCM-SHA384:AES128-SHA256:AES256-SHA256:AES128-SHA:AES256-SHA:AES:CAMELLIA:DES-CBC3-SHA:!aNULL:!eNULL:!EXPORT:!DES:!RC4:!MD5:!PSK:!aECDH:!EDH-DSS-DES-CBC3-SHA:!EDH-RSA-DES-CBC3-SHA:!KRB5-DES-CBC3-SHA";ssl_prefer_server_ciphers on;ssl session 配置
ssl_session_cache shared:SSL:10m;ssl_session_timeout 10m;HSTS 配置，这个对评分影响也比较大，但如果开启这个，需要全站开启 HTTPS 。
add_header Strict-Transport-Security "max-age=63072000; includeSubdomains; preload";完整配置文件
