Laravel 5.5 connection to MySQL

[smus]

I am quite new to Laravel(ver 5.5). There is an error while I am trying to create a table in an existing database:

Illuminate\Database\QueryException thrown with message "SQLSTATE[HY000] [1045] Access denied for user 'homestead'@'localhost' (using password: YES) 
(SQL: create table `books` (`id` int unsigned not null auto_increment primary key, `writer` varchar(255) not null, `title` varchar(500) not null, `description` text not null, `published` date not null, `copies` int not null, `created_at` timestamp null, `updated_at` timestamp null) default character set utf8 collate utf8_unicode_ci)"

 

This is config/database.php file:

'mysql' => [
'driver' => 'mysql',
'host' => env('DB_HOST', '127.0.0.1'),
'port' => env('DB_PORT', '3306'),
'database' => env('DB_DATABASE', 'mfa'),
'username' => env('DB_USERNAME', 'root'),
'password' => env('DB_PASSWORD', 'mypass'),
'unix_socket' => env('DB_SOCKET', ''),
'charset' => 'utf8',
'collation' => 'utf8_unicode_ci',
'prefix' => '',
'strict' => true,
'engine' => null,
],

.env:

APP_NAME=Laravel
APP_ENV=local

I have changed both files to adjust to my DBName, UserName and PassWord
