php artisan migrate command error : Illuminate\Database\QueryException : SQLSTATE[HY000] [2002] Connection refused

Question

我是 debian 用户

当我创建一个 laravel 项目（最新版本）和运行 php artisan migrate 命令时，我会遇到以下错误：

用5.4版本没问题

 Illuminate\Database\QueryException  : SQLSTATE[HY000] [2002] Connection refused (SQL: select * from information_schema.tables where table_schema = ticket and table_name = migrations)

  at /home/mostafa/W/laravel-projects/tickets/vendor/laravel/framework/src/Illuminate/Database/Connection.php:664
    660|         // If an exception occurs when attempting to run a query, we'll format the error
    661|         // message to include the bindings with SQL, which will make this exception a
    662|         // lot more helpful to the developer instead of just the database's errors.
    663|         catch (Exception $e) {
  > 664|             throw new QueryException(
    665|                 $query, $this->prepareBindings($bindings), $e
    666|             );
    667|         }
    668| 

  Exception trace:

  1   PDOException::("SQLSTATE[HY000] [2002] Connection refused")
      /home/mostafa/W/laravel-projects/tickets/vendor/laravel/framework/src/Illuminate/Database/Connectors/Connector.php:68

  2   PDO::__construct("mysql:host=127.0.0.1;port=3306;dbname=ticket", "root", "21900", [])
      /home/mostafa/W/laravel-projects/tickets/vendor/laravel/framework/src/Illuminate/Database/Connectors/Connector.php:68

  Please use the argument -v to see more details.

我很感激能提供帮助的人

我不是 100% 确定，但如果您尝试将 DB_HOST 从 127.0.0.1 更改为 localhost

，它可能会起作用

php artisan migrate command error : Illuminate\Database\QueryException : SQLSTATE[HY000] [2002] Connection refused

php artisan migrate command error : Illuminate\Database\QueryException : SQLSTATE[HY000] [2002] Connection refused

laravel

laravel-artisan

artisan-migrate
