Yii302将所有到本地主机的请求重定向到远程服务器

我将本地开发从windows PC迁移到Ubuntu，并且没有更改Yii上的任何设置。但当我访问时http://localhost，每个请求都重定向到我的服务器索引页(http://www.xxx.com/)。然而在窗口中，http://localhost将重定向到http://www.xxx.com但是localhost/controller/view不会。现在，所有到Yii的请求都被重定向到服务器（web根路径中未通过Yii的bootstrap index.php运行的其他文档不会被重定向）。可能是什么原因造成的？这是我的protected/config/main.hp:
