nginx ssl 更换问题

公司之前使用的是免费startssl证书，听说IOS 以后不信任这些免费的验证不严格的证书，公司果断购买了一个统配域名证书，其实不用貌似也没什么事，主要是提交app的时候得说明理由，被拒的可能性比较大。

在更换证书前想着保留原来免费的证书，然后使用新域名做测试。结果新域名使用了新证书，测试包老是不通过

我就纳闷了~怎么就不成了，到网上搜索到的问题都是说使用的是TLS1 ，而IOS要求是TLS1.2 。但是修改nginx配置，又重新编译nginx升级openssl版本

server
 {
   listen       443 ssl;
   include   ex_ssl.conf;
   server_name  www.ex.com;
      ssl_session_cache shared:SSL:1m;
      ssl_session_timeout 10m;
      ssl_prefer_server_ciphers  on;
      ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
      ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;
....
}

ex_ssl.conf

ssl on;
ssl_certificate /path/to/crt/ex.com.crt;
ssl_certificate_key /path/to/crt/ex.com.key;

而且肯定的是crt 文件和 key都没有问题　　

试了很多方法后使用了一条命令，才发现蹊跷所在

还好这条命令救了命了！

openssl s_client -connect you.domain.com:443

这条命令可以查看你的证书内容

看到以后看到了，虽然我使用了新的域名，但是解析以后，nignx还是匹配到了老域名的server中。证书内容是苹果不信任的那个证书，也就是应该不支持TLS1.2，就算我配置了TLS1.2，还是走的TLS1

~ openssl s_client -connect new.domain.com:
