push 服务器证书
钥匙串：登入--》证书，选项里面导出证书命名为cert.p12，跟密钥命名为key.p12
需要将上面的2个.p12文件转成.pem格式：
openssl pkcs12 -clcerts -nokeys -out cert.pem -in cert.p12
openssl pkcs12 -nocerts -out key.pem -in key.p12
如果需要对 key不进行加密：
openssl rsa -in key.pem -out key.unencrypted.pem
然后就可以 合并两个.pem文件, 这个ck.pem就是服务端需要的证书了。
cat cert.pem key.unencrypted.pem > ck.pem
4个pem，另外加上php文件，打包放到服务器上
