title: SQLSTATE[28000] [1045] Access denied for user 'root'@'localhost' (using password: YES)
body: <p>I'm new to Linux. I'm trying to run a project on localhost. It has worked but now I  got this error:</p>
  
  <p><code>SQLSTATE[28000] [1045] Access denied for user 'root'@'localhost' (using password: YES)</code> </p>
  
  <p>I tried to change password in this way:</p>
  
  <p><code>sudo dpkg-reconfigure mysql-server-5.5</code></p>
  
  <p>but still no result. 
  How to fix that?</p>
