title: php-fpm doesn't create .sock file
body: <p>I have an AWS server running on Amazon Linux.</p>
  
  <p>I used this guide to install php7 (bottom of the page): <a href="https://forums.aws.amazon.com/thread.jspa?messageID=695576" rel="noreferrer">https://forums.aws.amazon.com/thread.jspa?messageID=695576</a></p>
  
  <p>I would like to use nginx instead of Apache, so I've also installed the php70w-fpm and nginx packages. However, when I  <code>service start php-fpm</code>, it does not create a php-fpm.sock file anywhere on my server. I have checked in /var/run and have also ran <code>find / -name "*.sock"</code> which only returns <code>/var/run/rpcbind.sock</code>.</p>
