SSL 例程：SSL23_WRITE：ssl 握手失败，CentOS 7 上的 nginx

SSL 例程：SSL23_WRITE：ssl 握手失败，CentOS 7 上的 nginx

首先，我有什么：

OpenSSL 1.0.1e-fips 11 Feb 2013
nginx version: nginx/1.6.2
CentOS Linux release 7.0.1406 (Core)

并且，为了测试目的，自签名证书：

openssl req -x509 -sha256 -newkey rsa:2048 -keyout private_key.pem -out certificate.pem -days 365
openssl rsa -in private_key.pem -out certificate_key.pem
openssl dhparam -out dhparam.pem 4096

因此，问题如下 - 当我在浏览器中打开 test.example.com 时，出现 ERR_CONNECTION_RESET。在 nginx 错误日志中，我看到以下内容：

2015/02/07 03:18:34 [error] 27951#0: *17 no "ssl_certificate" is defined in server listening on SSL port while SSL handshaking, client: my.computers.ip.address, server: 0.0.0.0:443

如果我从第二个块中注释掉所有与 SSL 相关的内容server，注释掉整个第一个server块，并放入listen 80;第二个块，那么它就可以工作，因此我得出结论，问题与 SSL 有关。

因此，我开始寻找类似的案例。在我在这里检查的十几个问题中，以下两个问题似乎特别相关：

  1. SSL 例程：SSL23_WRITE：ssl 握手失败
  2. OpenSSL 握手失败

从第一个问题开始，我就明白我应该尝试执行openssl s_client -connect test.example.com:443和openssl s_client -tls1 -connect test.example.com:443。

对于前者，结果是：

[user@server nginx]# openssl s_client -connect test.example.com:443
CONNECTED(00000003)
140140897699744:error:140790E5:SSL routines:SSL23_WRITE:ssl handshake failure:s23_lib.c:177:

---

对于后者，结果是：

CONNECTED(00000003)

根据这些回复、列出的信息和其他一些问题以及其他地方提到的一些事项，我得出以下结论：

  • 我的 OpenSSL 版本可能存在错误。
  • 我可能错误配置了我的 SSL。具体来说，我可能对密码做了一些错误操作。
  • 我可能遇到了某种形式的不兼容问题。

从那时起，考虑到迁移到另一台服务器或擦除服务器以使用其他操作系统重建它是不可行的，我认为我有以下选择：

  • 以某种方式将我服务器上的 OpenSSL 升级到最近发布的 1.0.2 版本。问题在于兼容性以及如何升级 - 我似乎在我知道的存储库中找到了最新版本的 OpenSSL。
  • 如果可能的话，以某种方式安装第二个 OpenSSL 实例，或者安装一些 OpenSSL 替代方案（如果存在）。
  • 禁用加密，因为从长远来看这不是一个可行的生产解决方案。

我希望我错过了什么？希望如此，因为我宁愿避免想出任何相当激进的解决方案。

答案1

通过注释行解决

    listen       80 default_server;
    listen       443 default ssl;

，nginx.conf这样它们就变成

    #listen       80 default_server;
    #listen       443 default ssl;

答案2

我也收到“SSL 握手时，监听 SSL 端口的服务器中未定义 ssl_certificate”的错误信息。就我而言，解释要简单得多：我执行的是“service nginx start”，而不是“service nginx restart”。哎呀！
