解决方法

• 应该是CA证书验证失败造成的错误，下载个CA证书

[root@localhost ~]# wget http://curl.haxx.se/ca/cacert.pem
[root@localhost ~]# mv cacert.pem /usr/local/openssl/ssl/certs/cacert.pem
[root@localhost ~]# vim /yourpath/php.ini

• 修改cafile路径，保存

[openssl]
; The location of a Certificate Authority (CA) file on the local filesystem
; to use when verifying the identity of SSL/TLS peers. Most users should
; not specify a value for this directive as PHP will attempt to use the
; OS-managed cert stores in its absence. If specified, this value may still
; be overridden on a per-stream basis via the "cafile" SSL stream context
; option.
;openssl.cafile=
openssl.cafile=/usr/local/openssl/ssl/certs/cacert.pem
