在Yii中，您应该在位于protected / config文件夹的main.php文件中维护数据库配置。找到下面的部分并添加您的配置：

'components'=>array(
    [...]
    'db'=>array(
        'connectionString' => 'mysql:host=[YOUR_HOST];dbname=[YOUR_DATABASE]',
        'emulatePrepare' => true,
        'username' => 'admin',
        'password' => 'admin0',
        'charset' => 'utf8',
    ),
 [...]

Yii，Widgets，mysql db未选中
