1 PDOExc0019::（"SQLSTATE[HY000][2002]无法进行连接，因为目标机器主动拒绝它

Question

运行时出错：

PHP工匠迁移：重置

在my Laravel网站的根目录中：

  1   PDOException::("SQLSTATE[HY000] [2002] No connection could be made because
 the target machine actively refused it.
")
      C:\Users\jarro\Documents\Sites\homestead\vendor\laravel\framework\src\Illu
minate\Database\Connectors\Connector.php : 68

  2   PDO::__construct("mysql:host=127.0.0.1;port=3306;dbname=homestead", "homes
tead", "secret", [])
      C:\Users\jarro\Documents\Sites\homestead\vendor\laravel\framework\src\Illu
minate\Database\Connectors\Connector.php : 68

  Please use the argument -v to see more details.

当我运行-v时，我得到了以下信息：

 the target machine actively refused it.

我想我知道发生了什么。我不得不在PHPStorm中将数据库连接更改为192.168.10.10才能连接到MySQL，因为MySQL位于homestead VM（虚拟机）上，而我无法在本地连接到它，因为从技术上讲，它位于“不同的机器”上。然后我去寻找在哪里更改数据库信息。到目前为止，我的查询工作正常。所以我不知道为什么会有问题。我找到了/config/database.php并将每个用户名、密码、数据库名和主机更改为正确的内容：

'mysql' => [
    'driver' => 'mysql',
    'host' => env('DB_HOST', '192.168.10.10'),
    'port' => env('DB_PORT', '3306'),
    'database' => env('DB_DATABASE', 'homestead'),
    'username' => env('DB_USERNAME', 'homestead'),
    'password' => env('DB_PASSWORD', 'secret'),
    'unix_socket' => env('DB_SOCKET', ''),
    'charset' => 'utf8mb4',
    'collation' => 'utf8mb4_unicode_ci',
    'prefix' => '',
    'strict' => true,
    'engine' => null,
],

'pgsql' => [
    'driver' => 'pgsql',
    'host' => env('DB_HOST', '192.168.10.10'),
    'port' => env('DB_PORT', '5432'),
    'database' => env('DB_DATABASE', 'homestead'),
    'username' => env('DB_USERNAME', 'homestead'),
    'password' => env('DB_PASSWORD', 'secret'),
    'charset' => 'utf8',
    'prefix' => '',
    'schema' => 'public',
    'sslmode' => 'prefer',
],

'sqlsrv' => [
    'driver' => 'sqlsrv',
    'host' => env('DB_HOST', '192.168.10.10'),
    'port' => env('DB_PORT', '1433'),
    'database' => env('DB_DATABASE', 'homestead'),
    'username' => env('DB_USERNAME', 'homestead'),
    'password' => env('DB_PASSWORD', 'secret'),
    'charset' => 'utf8',
    'prefix' => '',
],

但这并没有真正起作用。我执行了命令

流浪者重新装载——规定

确保这不是问题。它在终端的错误信息中说

2
PDO::__construct（"mysql： host=127.0.0.1； port=3306； dbname=homestad"，"家庭tead"，"秘密"，[]）

127.0.0.1

当我明确地将/config中database.php文件中的主机更改为192.168.10.10时，这在尝试连接phpstorm时有效。

我很难学习laravel，我不知道如何将它改为192.168.10.10。有经验的人或至少有人能告诉我正确的方向，帮助我找到变量$dsn来更改传入的主机吗？

任何帮助都很感激！

Answer 1

尝试在根文件夹中编辑. env文件或在根文件夹中编辑.env.example文件

Answer 2

尝试运行php artisan缓存：清除或php artisan配置：清除

您还可能有一个.env文件覆盖它。
