问题：
[root@localhost opt]# git clone https://github.com/docker/docker.git
正克隆到 ‘docker‘...
fatal: unable to access ‘https://github.com/docker/docker.git/‘: Problem with the SSL CA cert (path? access rights?)
解决方法：
1，查看是否存在ca-bundle.crt，
[root@localhost opt]# ls /etc/pki/tls/certs/ca-bundle.crt
/etc/pki/tls/certs/ca-bundle.crt
2，如果存在，则可能是/etc/pki/tls/certs/ca-bundle.crt 过期。
3，查看该证书对应安装包
[root@localhost opt]# rpm -qf /etc/pki/tls/certs/ca-bundle.crt
ca-certificates-xxx.noarch
4，更新或重装ca-certificates
[root@localhost opt]# yum install ca-certificates
ca-certificates-xxx.noarch
重新git clone，OK!
