  <p>I am not able to get rid of the above error. I have created a <code>mysql.sock file</code> in <code>/Users/HPV/expertiza/tmp/sockets</code>. In the file I have written <code>mysql.default_socket =/expertiza/tmp/sockets/mysql.sock</code>. </p>
  
  <p>What am I doing wrong?</p>
  
  <p>Thanks!</p>
