Laravel - 未连接到 docker 上的数据库

Question

我正在尝试使用 postgres db 运行 Laravel。 Docker 构建工作正常，我可以通过 url 访问应用程序，并且可以连接到数据库。但 laravel 无法建立与数据库的连接。

我使用 phpstorm 客户端与数据库的连接有效：

但是当我在 env 文件中使用相同的凭据时：

然后我有以下错误。

Doctrine\DBAL\Driver\PDOException：SQLSTATE[08006] [7] 无法 连接到服务器：连接被拒绝 服务器是否在主机“127.0.0.1”上运行并接受 端口 5432 上的 TCP/IP 连接？

在 /var/www/html/vendor/doctrine/dbal/lib/Doctrine/DBAL/Driver/PDOConnection.php:31 27|父::__construct($dsn, (字符串) $user, (字符串) $password, (数组) $options); 28| $this->setAttribute(PDO::ATTR_STATEMENT_CLASS, [PDOStatement::class, []]); 29| $this->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); 30| } catch (\PDOException $异常) {

Answer 1

尝试在环境文件中将 DB_HOST 从 127.0.0.1 更改为 postgis，它对我有用。 像这样 ：- DB_HOST=postgis

Answer 2

我也遇到了同样的问题。它的工作原理是将 DB_HOST 更改为与 docker-compose 文件中的数据库服务相同的名称。
