'db'=>array(

        'username' => 'root',
        'password' => 'root',
        'charset' => 'utf8',
        'tablePrefix' => 'xcpt_', //表前缀
        'enableSlave'=>true,//从数据库启用
   'urgencyWrite'=>true,//紧急情况 主数据库无法连接 启用从数据库 写功能
    'masterRead'=>true,//紧急情况 从数据库无法连接 启用主数据库 读功能
        'slaves'=>array(//从数据库
            array(   //slave1
                'connectionString'=>'mysql:host=localhost;dbname=db_xcpt',
