    &#39;db&#39;=>array(
      &#39;connectionString&#39;=>DB_CONNECTION,
      &#39;username&#39;=>DB_USER,
      &#39;password&#39;=>DB_PWD,
      &#39;enableParamLogging&#39;=>true,

protected/commands/crons.php

<?php
defined(&#39;YII_DEBUG&#39;) or define(&#39;YII_DEBUG&#39;,true);
// including Yii
require_once(&#39;/../framework/yii.php&#39;);
// we&#39;ll use a separate config file
$configFile=&#39;/config/console.php&#39;;
// creating and running console application
Yii::createConsoleApplication($configFile)->run();

3. Add a specific scheduled task

protected/commands/TestCommand.php

class TestCommand extends CConsoleCommand
{
  public function run($args) {
    //todo
  }
}

4. Create a cronjob

30 0 * * * www php /path/to/crons.php Test >>/path/to/logs/test.log

5. Pass in the parameters to run($params) in the scheduled task

30 0 * * * www php /path/to/crons.php Test param1 param2 ...
