 CAfile: /etc/pki/tls/certs/ca-bundle.crt
 CApath: none

[root@jiankong ~]# curl https://wx.87th.cn
curl: (60) SSL certificate problem, verify that the CA cert is OK. Details:

errorSSL routinescertificate verify failed

解決辦法是更新本地CA證書庫。

方法一：

下載http://curl.haxx.se/ca/cacert.pem 替換/etc/pki/tls/certs/ca-bundle.crt

方法二：

使用update-ca-trust 更新CA證書庫。（CentOS6，屬于ca-certificates包）

方法三：

解決辦法是將簽發該證書的私有CA公鑰cacert.pem文件內容，追加到/etc/pki/tls/certs/ca-bundle.crt
