SSL 错误 : OCSP_basic_verify() failed

Question

我的日志文件 (error.log) 因这个错误而变成垃圾邮件:

2016/10/08 09:50:06 [error] 1014#1014: OCSP_basic_verify() failed 
(SSL: error:27069065:OCSP routines: OCSP_basic_verify:certificate verify error:
Verify error:self signed certificate in certificate chain) while requesting certificate 
status, responder: ocsp2.globalsign.com

我真的找不到这个问题的解决方案，你能帮我吗？

我正在使用 Ubuntu 16.04(NGINX + php7.0-fpm)

我的 example.conf 文件的一部分:

server {

为什么会出现此错误？我的证书不是自签名的

Answer 1

ssl_trusted_certificate "/var/www/httpd-cert/example/example.crt";

此设置应包含发布 OCSP 响应的可信 CA，即通常是发布者 CA。我的猜测是您的文件不包含必要的 CA，这就是为什么它无法按照使用 ssl_stapling_verify on 的要求验证 OCSP 响应的原因。

参见 the documentation有关此设置的更多信息。
