Question

运行时出错：

php artisan migrate：reset

在我的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.

当我跑-v时我得到了这个：

  1   PDOException::("SQLSTATE[HY000] [2002] No connection could be made because
 the target machine actively refused it.

我想我知道发生了什么事。我不得不将我的数据库连接更改为PHPStorm中的192.168.10.10以连接到MySQL，因为MySQL位于hometead VM（虚拟机）上并且我无法在本地连接到它，因为技术上它位于不同的机器上＃34 ;。那么我去寻找更改数据库信息的位置。我的查询截至目前为止。所以我不知道为什么会出现问题。我找到了/config/database.php并将每个用户名，密码，数据库名称，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' => '',
],

但是，这并没有真正帮助。我做了命令

vagrant reload --provision

确保这不是问题。它在终端

的错误消息中说

2
PDO :: __构建体（＆＃34; MySQL的：主机= 127.0.0.1 ;端口= 3306; DBNAME =宅＆＃34 ;, ＆＃34;家庭教育＆＃34;，＆＃34;秘密＆＃34;，[]）

127.0.0.1

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

我很难学习laravel，我很困惑如何将此更改为192.168.10.10。一个经验丰富的人或至少有人试图告诉我正确的方向，以帮助我找到变量$ dsn来改变传递给它的主机吗？

感谢任何帮助！

Answer 1

尝试跑步 php artisan cache:clear或 php artisan config:clear

您可能还有.env文件可能会覆盖它。

Answer 2

尝试在根文件夹中编辑.env文件，或者在根文件夹中也编辑.env.example文件
