I am using LARAVEL 5.2 and developing ADMIN panel and trying to integrate redis on 1.0 in LARAVEL. When i am trying to set set the variable name along with value it prompting an error:

No connection could be made because the target machine actively refused it. [tcp://127.0.0.1:6379]

The configurational changes i made it is given below:

1. In config/session.php file i replaced file with redis

('driver' => env('SESSION_DRIVER', 'redis'))

1. Under 'aliases' array under config/app.php file REDIS Facades already included

('Redis' => Illuminate\Support\Facades\Redis::class)

1. In .ENV file i replaced file with redis in SESSION_DRIVER variable

2. In database.php file the config for redis server is given below:

'redis' => [ 'cluster' => true,

    'default' => [
        'host' => env('REDIS_HOST', 'localhost'),
        'password' => env('REDIS_PASSWORD', null),
        'port' => env('REDIS_PORT', 6379),
        'database' => 0,
    ],
]

Below is my Controller code:

namespace App\Http\Controllers\Administrator;

use App\Http\Controllers\Controller;

use Redis;

use Illuminate\Http\Request;

use App\Http\Requests;

class MyController extends Controller {

public function __construct()
{}

public function myProfile(Request $request)
{
    $redis = Redis::connection();
    $adminName = $request->route('admin_name');
    if ( $redis ) { echo 'connection done'; } else { echo 'connection not done'; }
    Redis::set('name', $adminName);
    echo $redis->get('name');
}

}
