title: Set a persistent global MySQL parameter
body: <p>I set the following MySQL parameter:</p>
  
  <pre><code>set global wait_timeout=2147483
  </code></pre>
  
  <p>However, after server restart it reverted to its default value 28800. Isn't the <code>set</code> command persistent? In order to have this parameter persistent, should I edit a configuration file? Would that file be <code>C:\Program Files\MySQL\MySQL Server 5.5\my.ini</code>? If so, is it simply</p>
  
  <pre><code>wait_timeout=2147483
  </code></pre>
  
  <p>If so, under which section should it be in <code>my.ini</code></p>
