  <p>But when I try to start mysql I get this error:</p>
  
  <pre><code>ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: NO)
  </code></pre>
  
  <p>What is the problem? I can't seem to find any relevant solution.</p>
  
  <p>Any suggestion is appreciated. Thanks for the same.</p>
