报错信息：
fatal: unable to access ‘https://git.coding.net/xxxx/xx.git/’: Peer certificate cannot be authenticated with known CA certificates
然后一直咨询，coding.net的工作人员，最后解决方案：
Linux (CentOs 6) 添加证书：
1.安装 ca-certificates package:
yum install ca-certificates
2.启用dynamic CA configuration feature:
update-ca-trust force-enable
3.执行: update-ca-trust extract
