我安装了 DKAN 并且我短暂地工作过。然后我关闭了所有内容并尝试再次打开它，我收到以下错误消息：

The website encountered an unexpected error. Please try again later.

我相信这可能是我输入username的值admin，但是当我在笔记本电脑（我使用 Ubuntu 18）上创建它时，数据库是从root. 但是，我仍然不知道这是否真的是问题或我该如何解决

首先为您的 Drupal 实例创建一个新的数据库用户，而不是使用root.

通过mysql -u root -p在命令行上运行并输入密码。然后：

 CREATE USER drupal@localhost IDENTIFIED BY 'secretpassword';
 GRANT ALL ON drupaldatabase.* TO drupal@localhost;

其次，在其配置文件中配置 Drupal 应用程序以使用这个新用户。
