curl NSS error -8179 (SEC_ERROR_UNKNOWN_ISSUER)

嘗試分析

首先根據提示，我判斷是CA證書過時。因而對證書進行了更新

update-ca-trust

可是依然沒有解決問題。以後，嘗試了不少方法後，從新回來想一想，爲何不適用curl -v來獲取更多信息呢？因而使用該命令進行再次嘗試。

[root@localhost ~]# curl https://www.baidu.com -v

Just had the same problem with a Comodo Wildcard SSL cert.

After reading the docs the solution is to ensure you include the certificate chain file they send you in your config i.e.

　　　　　　　　SSLCertificateChainFile /etc/ssl/crt/yourSERVERNAME.ca-bundle
