Question

嗨，当我连接数据库时，我在应用程序中对laravel不熟悉我遇到了以下错误

SQLSTATE [HY000] [2002] php_network_getaddresses：getaddrinfo失败：名称或服务未知

public function createConnection($dsn, array $config, array $options)
{
$username = array_get($config, 'username');
$password = array_get($config, 'password');
**return new PDO($dsn, $username, $password, $options);**
}
 'mysql' => array(
        'driver'    => 'mysql',
        'host'      => 'HOST NAME',
        'port'      => '3306',
        'database'  => 'DBNAME',
        'username'  => 'DBUSER',
        'password'  => 'DBPASSWORD',
        'charset'   => 'utf8',
        'collation' => 'utf8_unicode_ci',
        'prefix'    => 'vox_',
    ),

Answer 1

这可能非常明显，但

 'host'      => 'HOST NAME',
        'port'      => '3306',
        'database'  => 'DBNAME',
        'username'  => 'DBUSER',
        'password'  => 'DBPASSWORD',

将这些设置为字符串HOST NAME，DBNAME等，对您的数据库凭据进行硬编码，看看它是否有效。

Answer 2

尝试使用IP地址替换主机名

Laravel和AWS RDS迁移无法连接数据库
