It's recommended that you use Composer to install Soupmix Cache Redis Adaptor.
$ composer require soupmix/cache-redis "~0.3"
require_once '/path/to/composer/vendor/autoload.php';
$rConfig = ['host'=> "127.0.0.1"];
$handler = new Redis();
$handler->connect(
$rConfig['host']
);
$cache = new Soupmix\Cache\RedisCache($handler);
