1 由于自己的curl是默认安装的，查看了下 不支持https协议
[root@izwz90bp6do7s3cr45cw6az ~]# curl --version
curl 7.29. (x86_64-redhat-linux-gnu) libcurl/7.29. NSS/3.21 Basic ECC zlib/1.2 . libidn/1.28 libssh2/1.4.

Features: AsynchDNS GSS-Negotiate IDN IPv6 Largefile NTLM NTLM_WB SSL libz unix- sockets
2 先安装openssl yum下安装很简单
yum install openssl
3 然后重新安装一遍curl，我看了自己的版本较老，就yum一下，是更新
yum install curl
[root@izwz90bp6do7s3cr45cw6az ~]# yum install curl
