php - 为什么 php artisan migrate 会导致“ Illuminate\Database\QueryException SQLSTATE[HY000] [2002] Connection denied”

Question

我试图建立一个 Laravel 项目，但是每当我点击php artisan migrate它都会导致这个错误

   Illuminate\Database\QueryException 

  SQLSTATE[HY000] [2002] Connection refused (SQL: select * from information_schema.tables where table_schema = src and table_name = migrations and table_type = 'BASE TABLE')

  at vendor/laravel/framework/src/Illuminate/Database/Connection.php:678
    674▕         // If an exception occurs when attempting to run a query, we'll format the error
    675▕         // message to include the bindings with SQL, which will make this exception a
    676▕         // lot more helpful to the developer instead of just the database's errors.
    677▕         catch (Exception $e) {
  ➜ 678▕             throw new QueryException(
    679▕                 $query, $this->prepareBindings($bindings), $e
    680▕             );
    681▕         }
    682▕

      Illuminate\Foundation\Console\Kernel::handle()

我在 WSL Ubuntu 20.04LTS 中使用 laravel/framework:^8.12。我知道这是一个非常常见的问题，但没有一个解决方案对我有用。
