无法使用 Laravel 5 连接到 Mysql 服务器

哈迪扎德

当我向 Laravel 安装添加 MySQL 连接时,它似乎不起作用并出错:

QueryException SQLSTATE[HY000] [2002] 连接尝试失败,因为连接方在一段时间后没有正确响应,或者由于连接的主机未能响应而建立的连接失败。

我希望你们知道,因为我不知道。

1,你替换default'default' => env('DB_DRIVER', 'mysql')

2,你需要添加关键'mysql' => [connections

    'connections' => [

    'sqlite' => [
        'driver' => 'sqlite',
        'database' => env('DB_DATABASE', database_path('database.sqlite')),
        'prefix' => '',
    ],
    'mysql' => [
        'driver' => 'mysql',
        'host' => env('DB_HOST', 'localhost'),
        'port' => env('DB_PORT', '3306'),
        'database' => env('DB_DATABASE', 'anirun'),
        'username' => env('DB_USERNAME', 'root'),
        'password' => env('DB_PASSWORD', ''),
        'unix_socket' => env('DB_SOCKET', ''),
        'charset' => 'utf8mb4',
        'collation' => 'utf8mb4_unicode_ci',
        'prefix' => '',
        'strict' => true,
        'engine' => null,
    ],

    'pgsql' => [
        'driver' => 'pgsql',
        'host' => env('DB_HOST', 'localhost'),
        'port' => env('DB_PORT', '5432'),
        'database' => env('DB_DATABASE', 'forge'),
        'username' => env('DB_USERNAME', 'forge'),
        'password' => env('DB_PASSWORD', ''),
        'charset' => 'utf8',
        'prefix' => '',
        'schema' => 'public',
        'sslmode' => 'prefer',
    ],

    'sqlsrv' => [
        'driver' => 'sqlsrv',
        'host' => env('DB_HOST', 'localhost'),
        'port' => env('DB_PORT', '1433'),
        'database' => env('DB_DATABASE', 'forge'),
