Dio*_*ius 11 openssl certificate-authority apache-2.4
不知何故,今天突然我的 Seafile 客户端抛出了这个错误。我不相信这是一个 seafile 问题,因为我的 openssl 抛出了完全相同的错误:

对我来说,链条部分看起来正是它应该的样子。apache conf 也应该没问题:

我找不到我的问题是什么......(ca-certificates 安装在我的 lubuntu 14.04 上)。他们的网站不适用,因为他们链接了他们的 1 类证书,但我的网站是由他们的 2 类证书颁发的。

OpenSSL 的此错误意味着程序无法验证证书的颁发者或所提供链的最顶层证书。在某些情况下可能会发生这种情况,例如:
未提供受信任根证书的本地数据库,因此 OpenSSL 不会查询。要明确提供证书的路径,请使用-CApath
或-CAfile
选项。对于 Debian 和 Ubuntu,例如:
-CApath /etc/ssl/certs/
-CAfile /etc/ssl/certs/ca-certificates.crt

从而导致
openssl s_client -connect example.com:443 -CApath /etc/ssl/certs/
openssl s_client -connect example.com:443 -CAfile /etc/ssl/certs/ca-certificates.crt
Run Code Online (Sandbox Code Playgroud)后者需要更多信息。自 2009 年以来,Ubuntu 中有一个OpenSSL的公开错误报告:
使用 -CApath 似乎将 -CAfile 设置为 /etc/ssl/certs/ca-certificates.crt 的默认值。
不管你给出的 path by 是什么-CApath
,它都可以工作,因为-CAfile
也被设置为它的默认值(之前是空的)。因此,不要依赖 OpenSSL 的默认行为来通过本地证书数据库验证证书,这可能是假的!
