SQLSTATE[HY000] [1045] laravel 中的用户拒绝访问

Question

我想将项目从主机移到我的主机。 但是在移动和更改.env文件和config/database.php文件后，出现了这个错误：

SQLSTATE[HY000] [1045] 用户'test_root'@'mailserver63.mylittledatacenter.com'的访问被拒绝（使用密码：YES）（SQL：select * from orders where status not in（CANCELLED, COMPLETED ) 和 api_order_id 不是 RAND() 限制 15) 的空订单)

这是配置/数据库代码：

我不知道与mailserver63.mylittledatacenter.com 有什么联系，也不知道这句话在我的项目中的什么位置。 我什至使用了一个工具在我的项目文件中查找 mylittledatacenter 短语。在我的项目文件中，我没有找到任何带有该术语的文件软件。

Answer 1

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=database_name
DB_USERNAME=username
DB_PASSWORD=password

解决此错误或在 Laravel 中设置数据库的三个步骤：

1. 首先在项目.env文件中添加数据库名称（DB_DATABASE=database_name）。

2. 然后在项目.env文件中添加数据库的用户名（DB_USERNAME=username）。

3. 然后在项目.env文件中添加数据库的密码（DB_PASSWORD=password）。

按照上述步骤解决了这个错误 SQLSTATE[HY000] [1045] Laravel 中的用户访问被拒绝
