title: Can't log into phpmyadmin using root and no password
body: <p>I'm using ubuntu, and i install my php and mysql using <a href="http://howtoubuntu.org/how-to-install-lamp-on-ubuntu" rel="nofollow noreferrer">this</a> way.
  When mysql ask me about password(several times) i always let it empty and hit 'OK'.
  Now the problem is i cant login into phpmyadmin.
  I have tried some ways i found on this site, and got my config like this.</p>
  
  <pre><code>&lt;?php

  <p>But still phpmyadmin always ask for login, i also get this error massage when trying to log into without filling password <code>#1698 - Access denied for user 'root'@'localhost'</code>.
  The only way i can access mysql is by using <code>sudo mysql -u root</code>.
  But still, my expectation is not to only can log into phpmyadmin, but to access phpmyadmin without login via login page.</p>
