title: InnoDB missing from MySQL
body: <p>I have no idea of what I have done here, but my InnoDB engine seems to have gone from my MySQL  server. I recently upgraded it from the dotdeb repository, then installed <code>mysql-server</code>.</p>
  
  <p>There is no mention of InnoDB in my <code>my.cnf</code> except some comments which explain InnoDB is enabled by default, which I don't understand. There is also no mention of InnoDB in <code>SHOW ENGINES</code>.</p>
  
  <p>Is there something I'm missing here?</p>
  
  <p>If it matters, my MySQL server version is: <code>5.5.24-1~dotdeb.1 (Debian)</code>.</p>
  
  <p>EDIT: <code>SHOW ENGINES</code>:</p>
  
  <pre><code>mysql&gt; SHOW ENGINES;
