php - Laravel msql配置%db_name%缓存问题

问题描述

我正在尝试使用 laravel 配置 msql db，但我遇到了一个奇怪的问题。在网上搜索后，我仍然没有完成我的迁移。

在我的 .env 我有

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT='%db_port%'
DB_DATABASE='forge'
DB_USERNAME='root'
DB_PASSWORD='password'

所以在改变 .env 之后我做了，在那之后php artisan cache:clear我 得到了php artisan config:cachephp artisan migrate

   Illuminate\Database\QueryException  : SQLSTATE[HY000] [2002] php_network_getaddresses: getaddrinfo failed: nodename nor servname provided, or not known (SQL: select * from information_schema.tables where table_schema = %db_name% and table_name = migrations)

  at /Users/p/Documents/Project/hub-family-server/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   Doctrine\DBAL\Driver\PDOException::("SQLSTATE[HY000] [2002] php_network_getaddresses: getaddrinfo failed: nodename nor servname provided, or not known")
      /Users/p/Documents/Project/hub-family-server/vendor/doctrine/dbal/lib/Doctrine/DBAL/Driver/PDOConnection.php:31

  2   PDOException::("PDO::__construct(): php_network_getaddresses: getaddrinfo failed: nodename nor servname provided, or not known")
      /Users/p/Documents/Project/hub-family-server/vendor/doctrine/dbal/lib/Doctrine/DBAL/Driver/PDOConnection.php:27

  Please use the argument -v to see more details.

现在与应用程序交互php artisan tinker并检查

Psy Shell v0.9.9 (PHP 7.2.19 — cli) by Justin Hileman
>>> env('DB_USERNAME')
=> null
>>> config('database.connections.mysql.database')
=> "%db_name%"
>>> env('DB_HOST')
=> null
>>> env('DB_USERNAME')
=> null
>>>

所以我不确定发生了什么，我也确实更新了 dbal，composer require doctrine/dbal但没有做任何事情。有人可以帮我理解发生了什么谢谢。

解决方案

我认为问题出在 DB_PORT 上，它应该是 3306，或者根据服务器设置。更改 DB_PORT，如果所有其他数据都正确，它应该可以工作。
