我正在尝试从我创建的扩展中迁移两个表。我在XAMPP上创建了它，我的迁移工作正常（测试了几次）。然后我决定在另一台服务器上测试它，我得到的错误是：
Exception 'yii\db\Exception' with message 'SQLSTATE[HY000] [1045] Access denied for user 'ivailo'@'localhost' (using password: YES)'

我的Yii2是全新安装的。仅通过composer添加了扩展名。数据库配置正确（我们使用多年的用户和密码）。我创建了测试表并执行了一行Yii::$app->db->createCommand('INSERT INTO test VALUES (1,'testname')')并且传递正常。这样我决定连接是好的。但是通过控制台迁移php yii migrate/up --migrationPath=@vendor/********/*******/migrations，它给了我上面的错误。想提一下，我不熟悉我们的服务器配置（我所知道的是操作系统：Ubuntu 14.04 H：Apache2），如果问题是以某种方式解决的话，系统管理完全。提前谢谢！
