使用git通过https方式从github clone git repo源码时，报错如下：
| 1 2 3 | Cloning into 'git'...
fatal: unable to access 'https://github.com/git/git.git/': SSL certificate problem, verify that the CA cert is OK. Details:
error:14090086:SSL routines:SSL3_GET_SERVER_CERTIFICATE:certificate verify failed
|
开启curl verbose选项（用于调试）并重新执行git clone，详细报错信息：
| 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 | $ export GIT_CURL_VERBOSE=1
$ git clone https://github.com/git/git.git

从错误提示可知，git通过curl访问https地址时，未能在本机未找到ca证书，从而导致ssl certificate verify failed。
解决方法：
Setp1：从curl官网下载cacert.pem文件（下载链接参见这里，关于curl的Server SSL Certificates细节参见这里，其中提到，从curl 7.18.0开始，编译安装curl时默认安装ca证书，而我机器的curl version=7.12.1，curl –version可查看）：
| 1 2 3 | ~$ mkdir ~/tools/https-ca
~$ cd ~/tools/https-ca
~$ curl http://curl.haxx.se/ca/cacert.pem -o cacert.pem
|
Step2：终端执行下面的命令，以便为git配置ca认证信息：
| 1 | ~$ git config --global http.sslCAInfo /home/slvher/tools/https-ca/cacert.pem
|
可打开~/.gitconfig确认cainfo配置成功写入git配置文件
完成以上两步后，执行git clone https://github.com/git/git.git成功，问题解决。
