title: Linux APNS server which cert should I create?
body: <p>I am going to use a linux server for push notifications.</p>
  
  <p>Is the following correct?</p>
  
  <ol>
  <li>Generate a CSR of the <strong>linux</strong> server</li>
  <li>Upload the file to Apple to generate a cert</li>
  <li>Change this cer to pem and then conbine with my private key pem of linux</li>
  <li>Use the combined pem in my code</li>
  </ol>
  
  <p>Is this correct? Since I get confused by the Apple document, I can now only test push notifications in my mac book, and can't test on other servers.</p>
