title: MySQL slave I/O thread not running
body: <p>I have set up replication for MySQL server. I can connect from the slave machine to the master server using the replication user/password. I have got the slave SQL thread running, but the slave <a href="http://en.wikipedia.org/wiki/Input/output" rel="nofollow noreferrer">I/O</a> thread is not running and the slave I/O status comes as empty when checked using 'show slave status'. What could be the problem?</p>
  
  <p>How do I solve this? Restarting the slave does not help. </p>
  
  <p>This was my bad: Instead of giving a 'replication slave' privilege to <code>*.*</code>, I was only giving it for <code>my_db.*</code>.</p>
