SQLSTATE[HY000] [2002] Connection refused.

But my database working perfect since I already able to migrate the tables. Whats possible solution could be? check attached image (I'm using Ubuntu 16.04)

Answer 1

Try changing your DB_HOST from 127.0.0.1 to localhost. and if still not working try using the default mysql port to 3306

Answer 2

if you use laravel maybe your PDO PHP Extension not set. in your php.ini uncomment extension=php_pdo_mysql.dll

if you had no access to php.ini do this: add this to config/database.php in mysql section

'options' => [PDO::ATTR_EMULATE_PREPARES => true],

your code should be like this:

'mysql' => [
        'driver' => 'mysql',
        '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',
        'options' => [PDO::ATTR_EMULATE_PREPARES => true],
        'prefix' => '',
        'strict' => true,
        'engine' => null,
    ],

Answer 3

If you are trying to run php artisan migrate from host machine you need to set in .env conf file DB_PORT=33060 as that is a port vagrant/Homestead is listening on. But when i change that my application stop working. So i suggest ssh to vagrant and run php artisan migrate from VM and you will have no problems.
