PHP Artisan 迁移 - 用户“root”@“localhost”访问被拒绝

Question

我在运行“php artisan migrate”命令时遇到问题，这是我遇到的错误

SQLSTATE[HY000] [1045] Access denied for user 'root'@'localhost' (using password: NO) (Connection: mysql, SQL: select table_name as `name`, (data_length + index_length) as `size`, table_comment as `comment`, engine as `engine`, table_collation as `collation` from information_schema.tables where table_schema = 'e-commerce-web-proto' and table_type in ('BASE TABLE', 'SYSTEM VERSIONED') order by table_name)

    827▕             }

    831▕             );
    832▕         }
    833▕     }

我已经更改了数据库名称以匹配我使用的数据库名称，还运行

php artisan config:cache

。我还需要做什么吗？

这是我的环境。文件

DB_CONNECTION=mysql
DB_HOST=localhost
DB_PORT=3306
DB_DATABASE=e-commerce-web-proto
DB_USERNAME=root
DB_PASSWORD=

这是我的数据库配置

'mysql' => [
            'driver' => 'mysql',
            'url' => env('DATABASE_URL'),
            'host' => env('DB_HOST', 'localhost'),
            'port' => env('DB_PORT', '3306'),
            'database' => env('DB_DATABASE', 'forge'),
            'username' => env('DB_USERNAME', 'forge'),
            'password' => env('DB_PASSWORD', ''),

Answer 1

mysql -u root -p

verify your teminal can login.

next 

php artisan config:clear
php artisan cache:clear


'mysql' => [
    'driver' => 'mysql',
    'url' => env('DATABASE_URL'),
    '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', ''),
    'unix_socket' => env('DB_SOCKET', ''),
    'charset' => 'utf8mb4',
    'collation' => 'utf8mb4_unicode_ci',
    'prefix' => '',
    'strict' => true,
    'engine' => null,
    'options' => extension_loaded('pdo_mysql') ? array_filter([
        PDO::MYSQL_ATTR_SSL_CA => env('MYSQL_ATTR_SSL_CA'),
    ]) : [],
],

 check MySQL service is running
 sudo service mysql status
 
 sudo service mysql start

 now try 
 php artisan migrate
