1、Peer’s Certificate issuer is not recognized

代码如下:

    [root@jiankong ~]# curl  -v  https://wx.87th.cn

*   CAfile: /etc/pki/tls/certs/ca-bundle.crt

    CApath: none

*   Peer's certificate issuer is not recognized: 'CN=Encryption Everywhere DV TLS CA - G2,OU=www.digicert.com,O=DigiCert Inc,C=US'

2、SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed

   [root@jiankong ~]# curl https://wx.87th.cn

    curl: (60) SSL certificate problem, verify that the CA cert is OK. Details:

    error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed

解决办法是更新本地CA证书库。

方法一：

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

方法二：

使用update-ca-trust 更新CA证书库。（CentOS6，属于ca-certificates包）

方法三：

解决办法是将签发该证书的私有CA公钥cacert.pem文件内容，追加到/etc/pki/tls/certs/ca-bundle.crt
