Drupal 8连接获得PDO权限被拒绝

时间：2019-06-07 11:00:28

标签： pdo drupal-8

我是Drupal 8的新手，并且从构建示例站点开始。我的所有设置都正确，但是下面出现了PDO连接错误。我很确定这与主机名有关，但我不知道是什么。

我的settings.php看起来像这样：

$databases['default']['default'] = array (
   'database' => 'website_pet',
   'username' => 'drupal',
   'password' => 'mypass',
   'host' => '127.0.0.1',
   'port' => '3306',
   'driver' => 'mysql',
   'prefix' => '',
   'collation' => 'utf8mb4_general_ci',
 );

在my.cnf中，我添加了：

max_allowed_packet=100M

我的httpd错误日志显示：

我可以通过以下两种方式连接到数据库：

mysql -u drupal -pmypass -h 127.0.0.1 website_pet
mysql -u drupal -pmypass -h localhost website_pet

所以我知道这不是数据库的权限错误。该网站托管在云中，我正在通过SSH隧道（localhost：1180）访问它。如果尝试将selinux暂时设置为宽松，但这没有帮助。

有人可以指出这是怎么回事吗？

更新：重新启动等后，错误有所改变，网页显示：

首先，对于Drupal使用root用户是一个坏主意-如果有人发现一个弱点，您只是让他们访问数据库中的所有内容，甚至可能访问系统的其余部分。虽然这可能是一个开发系统，但养成不良习惯是不明智的。

无论如何，还是要解决这个问题。 MySQL需要注意的一件事是，出于性能原因，通常通过Unix域套接字（即文件系统中的“文件”）来转移本地主机连接。有时，由于套接字不存在或建立连接的用户无法访问套接字，或者用户在MySQL权限表中将“ localhost”包含在“ 127.0.0.1”中时，您会得到拒绝权限失败，反之亦然。最后，在混合使用IPv6的情况下，某些OS网络堆栈现在默认为“ :: 1”（IPv6等效于127.0.0.1）。

再次检查数据库权限表包含的内容：所有三个（主机，用户，密码）必须匹配才能授予访问权限。我的经验是通配符主机：“％”不可靠，因此避免使用它。

您可以尝试在drupal和MySQL的权限表中将127 ...设置为“ localhost”。

经过大量实验后，问题似乎源于在CentOS 7上安装PHP 7.2（仅PHP 5.x附带）

永远无法使其正常工作，但是在构建了一个包含PHP 7的新ubuntu之后，一切似乎都可以正常工作。

我无法追溯到单个模块/设置/包装。但是解决方案是不要在CentOS 7上尝试（对PHP7x软件包使用remi repo）

答案 2 :(得分：0)

SELinux参与其中的可能性很高。假设因为您使用的是127.0.0.1而不是localhost？我遇到了完全相同的错误（但是我确实尝试连接到远程主机），而这个answer帮助了我。

因此，不久之后：
