请教 Redis cluster 配置使用问题

问题描述：在 laravel 5.8 使用 cache + redis cluster 一直去连接本地 redis 服务器。

版本信息：

"require": {
        "php": "^7.1.3",
        "dingo/api": "^2.2",
        "fideloper/proxy": "^4.0",

        "laravel/tinker": "^1.0",
        "predis/predis": "^1.1",
        "ext-json": "*"
    },

.env 中

    CACHE_DRIVER=redis

cache.php 配置：

    'redis' => [
            'driver' => 'redis',
//            'connection' => 'cache',
            'connection' => 'default',
        ],

database.php 配置：

    'redis' => [
       // 'cluster' => 'true',
        'client' => env('REDIS_CLIENT', 'predis'),

        'options' => [
            'cluster' => env('REDIS_CLUSTER', 'redis'),
//            'parameters' => ['password' => env('REDIS_PASSWORD', null)],
        ],

        'clusters' => [
            'default' => [
                [
                    'host' => env('REDIS_HOST_A'),
                    'password' => env('REDIS_PASSWORD_A'),
                    'port' => env('REDIS_PORT_A', 6379),
                    'database' => env('REDIS_DB_A', 0),
                ],
                [
                    'host' => env('REDIS_HOST_B'),
                    'password' => env('REDIS_PASSWORD_B'),
                    'port' => env('REDIS_PORT_B', 6379),
                    'database' => env('REDIS_DB_B', 0),
                ],
                [
                    'host' => env('REDIS_HOST_C'),
                    'password' => env('REDIS_PASSWORD_C'),
                    'port' => env('REDIS_PORT_C', 6379),
                    'database' => env('REDIS_DB_C', 0),
                ],
                [
                    'host' => env('REDIS_HOST_D'),
                    'password' => env('REDIS_PASSWORD_D'),
                    'port' => env('REDIS_PORT_D', 6379),
                    'database' => env('REDIS_DB_D', 0),
                ],
                [
                    'host' => env('REDIS_HOST_E'),
                    'password' => env('REDIS_PASSWORD_E'),
                    'port' => env('REDIS_PORT_E', 6379),
                    'database' => env('REDIS_DB_E', 0),
                ],
                [
                    'host' => env('REDIS_HOST_F'),
                    'password' => env('REDIS_PASSWORD_F'),
                    'port' => env('REDIS_PORT_F', 6379),
                    'database' => env('REDIS_DB_F', 0),
                ],
            ],
        ],
//        'cache'   => [
//            'host'     => env('REDIS_HOST', '127.0.0.1'),
//            'password' => env('REDIS_PASSWORD', null),
//            'port'     => env('REDIS_PORT', 6379),
//            'database' => env('REDIS_CACHE_DB', 1),
//        ],

    ],

请帮忙看看哪里配置的不对？clusters 中的 redis 无密码，配置为 null 。一直在连接本地 redis 服务器。

打印了下

    "tcp://127.0.0.1:6379"

因为本地 redis 有密码，所以一直报

message: "NOAUTH Authentication required."
