title: save MySQL Packet Size after shutdown
body: <p>Hi there<br>
  I have problem with my mysql server.<br>
  I have windows 7, apche 2.2,php5.2 and mysql 5.0.51b-community-nt on my laptop(localhost)
  I ran this query in mysql command line :</p>
  
  <pre><code>set global max_allowed_packet=16*1024*1024;
  </code></pre>
  
  <p>but after restart max_allowed_packet is 1MB(default).  </p>
  
  <p>What should I do to save changes, and keep them after shutdown?</p>
