If you are receiving an error that the private doesn't match the certificate or that a certificate that you installed to a site is not trusted, try one of these commands. If you are trying to verify that an SSL certificate is installed correctly, be sure to check out the SSL Checker.
Check an MD5 hash of the public key to ensure that it matches with what is in a CSR or private key
`
openssl x509 -noout -modulus -in certificate.crt | openssl md5
openssl rsa -noout -modulus -in privateKey.key | openssl md5
openssl req -noout -modulus -in CSR.csr | openssl md5
`
Check an SSL connection. All the certificates (including Intermediates) should be displayed
openssl s_client -connect www.paypal.com:443

创建headless service

Zookeeper Stateful Set 需要创建一个headless的service来控制域名, 包括两个端口2888/3888，server／2888端口是为了follow与leader通信用，3888端口是为了leader选举
