Php artisan 无法迁移

Question

您好，我在使用 php artisan migrate 在我的 vps 服务器上进行迁移时遇到问题。我已经安装了apache2和mysql。我可以通过 mysql -u root -p 使用密码“pass#$”连接到我的数据库。这是我的环境。

APP_NAME=Laravel
APP_ENV=local
APP_KEY=**
APP_DEBUG=true
APP_URL=http://localhost

LOG_CHANNEL=stack

DB_CONNECTION=mysql
DB_HOST=localhost
DB_PORT=3306
DB_DATABASE=mysql
DB_USERNAME=root
DB_PASSWORD=pass#$

BROADCAST_DRIVER=log
CACHE_DRIVER=file
QUEUE_CONNECTION=sync
SESSION_DRIVER=file
SESSION_LIFETIME=120

REDIS_HOST=127.0.0.1
REDIS_PASSWORD=null
REDIS_PORT=6379

MAIL_DRIVER=smtp
MAIL_HOST=smtp.mailtrap.io
MAIL_PORT=2525
MAIL_USERNAME=null
MAIL_PASSWORD=null
MAIL_ENCRYPTION=null

AWS_ACCESS_KEY_ID=
AWS_SECRET_ACCESS_KEY=
AWS_DEFAULT_REGION=us-east-1
AWS_BUCKET=

PUSHER_APP_ID=
PUSHER_APP_KEY=
PUSHER_APP_SECRET=
PUSHER_APP_CLUSTER=mt1

MIX_PUSHER_APP_KEY="${PUSHER_APP_KEY}"
MIX_PUSHER_APP_CLUSTER="${PUSHER_APP_CLUSTER}"

我从数据库中获取了这些信息:

+--------------------+
| Database           |

| information_schema |
| laravel            |
| mysql              |

+--------------------+

以及mysql中的这个表信息

+---------------------------+

更重要的是，我首先在我的电脑上创建了我的项目，现在我只能从我的 github 存储库中获取它。当我访问我的网站 IP 时，我可以看到我所有的网站和 View 。

我尝试将.env文件127.0.0.1更改为本地主机，尝试通过php artisan config:clear和php artisan cache:clear清除配置，但它仍然不起作用。

编辑:我忘了

php artisan migrate

   Illuminate\Database\QueryException  : SQLSTATE[HY000] [1045] Access denied for user 'root'@'localhost' (using password: YES) (SQL: select * from information_schema.tables where table_schema = mysql and table_name = migrations and table_type = 'BASE TABLE')

    672|         }
    673|

  Exception trace:

      /home/projects/test/ArduinoWeather/vendor/laravel/framework/src/Illuminate/Database/Connectors/Connector.php:70

  2   PDO::__construct("mysql:host=localhost;port=3306;dbname=mysql", "root", "pass", [])
      /home/projects/test/ArduinoWeather/vendor/laravel/framework/src/Illuminate/Database/Connectors/Connector.php:70

  Please use the argument -v to see more details.

Answer 1

确保您的 mysql 正在端口 3306 上运行，并且您的用户名和密码正确。然后转到您的项目文件夹并

config/database.php

更改这些:

'host' => env('DB_HOST', '127.0.0.1'),
'port' => env('DB_PORT', '3306'),
'database' => env('DB_DATABASE', 'forge'),
'username' => env('DB_USERNAME', 'forge'),
'password' => env('DB_PASSWORD', ''),

而不是使用 .env 使用静态内联用户名和密码，例如:

'usename' => 'root',
'password' => 'your password'

看看它是否有效。
