title: What's the default password of mariadb on fedora?
body: <p>I installed mysql through yum just now and the OS fedora installed mariadb for me.
  I know mariadb is a new branch of mysql, but I can't understand why it does not ask me for setting the password.
  I have tried for 123456 and so on, but I failed. 
  My fedora is new, and this is the first time to install mysql/mariadb.
  What should I do for it?</p>
