【问题描述】：
我有一个 Drupal 网站源代码目录和当前 Drupal 网站的 SQL 文件。我已经为该服务器建立了一个空白网站（我们有自己的服务器）和使用 PHPMyAdmin 的新数据库。我已将 SQL 文件添加到数据库，并使用新的用户名、密码和数据库名称更新了站点 > 默认 > settings.php。
但是，在尝试加载网站时出现错误：
Warning: PDO::__construct(): php_network_getaddresses: getaddrinfo failed: No such host is known. in DatabaseConnection->__construct() (line 307 of D:\wwwroot\xxxxxxx\includes\database\database.inc).
Warning: PDO::__construct(): php_network_getaddresses: getaddrinfo failed: No such host is known. in DatabaseConnection->__construct() (line 307 of D:\wwwroot\xxxxxxx\includes\database\database.inc).

PDOException: SQLSTATE[HY000] [2002] php_network_getaddresses: getaddrinfo failed: No such host is known. in lock_may_be_available() (line 167 of D:\wwwroot\xxxxxxx\includes\lock.inc).
Warning: PDO::__construct(): php_network_getaddresses: getaddrinfo failed: No such host is known. in DatabaseConnection->__construct() (line 307 of D:\wwwroot\xxxxxxx\includes\database\database.inc).
我是否需要更改我创建的数据库或 settings.php 文件中的主机信息？因为我还没有改变任何东西？

似乎您的服务器无法解析数据库服务器名称：拼写正确吗？
