Drupal无法启动

我严格按照您网站的说明进行操作（"www.drupalbook.ru/content/slozhno-li-sozdavat-saity-na-drupale"），但在“现在如果我们访问 http://sitename/，应该看到以下窗口:”这句话之后，出现了错误：Deprecated: Function ereg() is deprecated in Z:\home\sitename\www\includes\file.inc on line 646 Warning: Cannot modify header information - headers already sent by (output started at Z:\home\sitename\www\includes\file.inc:646) in Z:\home\sitename\www\includes\install.inc on line 574 Warning: Cannot modify header information - headers already sent by (output started at Z:\home\sitename\www\includes\file.inc:646) in Z:\home\sitename\www\includes\install.inc on line 575 这该如何解决？
