title: It's mysql or mysqld?
body: <p>recently I've installed Mysql and it turns out the service name of it is "mysql" (there no "d" suffix), I remember before this time it's "mysqld" all the time. And when you type in "sudo service mysqld status" it would say this service does not exists.</p>
  
  <p>Is there any difference between this two? Or it's a total diffrent version of mysql?</p>
