SSL 链不完整

Question

使用 Let's Encrypt 创建 7 个 SSL 证书后，我偶然发现了这个错误。我已正确设置所有配置，并在 [SSLLabs.com][1] 上扫描了我的整个站点以查找 SSL 漏洞，它告诉我我的服务器的证书链不完整。

我是运行 CentOS Linux release 7.2.1511 (Core) 作为 NginX 的反向代理。我的配置是：

# GhostAntiDDoS
server {
  listen  443 ssl;
  server_name  ghostantiddos.com *.ghostantiddos.com;
  ssl  on;
  ssl_certificate  /etc/letsencrypt/live/ghostantiddos.com/cert.pem;
  ssl_certificate_key  /etc/letsencrypt/live/ghostantiddos.com/privkey.pem;
  ssl_dhparam  /etc/ssl/certs/dhparam.pem;
  ssl_session_timeout  5m;
  ssl_prefer_server_ciphers  on;
  ssl_protocols  TLSv1 TLSv1.1 TLSv1.2;
  ssl_ciphers  'ECDHE-RSA-AES128-GCM-SHA256:ECDHE-ECDSA-AES128-GCM-SHA256:ECDHE-RSA-AES256-GCM-SHA384:ECDHE-ECDSA-AES256-GCM-SHA384:DHE-RSA-AES128-GCM-SHA256:DHE-DSS-AES128-GCM-SHA256:kEDH+AESGCM: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:DHE-RSA-AES128-SHA256:DHE-RSA-AES128-SHA:DHE-DSS-AES128-SHA256:DHE-RSA-AES256-SHA256:DHE-DSS-AES256-SHA:DHE-RSA-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';
  add_header Strict-Transport-Security max-age=15768000;
  # Bulletin

  #limit_req zone=req_limit_per_ip burst=5 nodelay;
  client_body_timeout 5s;
  client_header_timeout 5s;
  ....

其余部分隐藏起来，因为它们会暴露我的出身。如果有人可以帮助我，我会很棒！

替换

certificate /etc/letsencrypt/live/ghostantiddos.com/cert.pem

来自

certificate /etc/letsencrypt/live/ghostantiddos.com/fullchain.pem

然后用 https://ssllabs.com

再次测试

SSL 链不完整

SSL Chain Incomplete

ssl

https

webserver

nginx

lets-encrypt
