php - Connection denied {"exception":"[object] (RedisException(code: 0): Connection refused, Laravel Horizo​​n 每 5 秒两次，但 Horizo​​n 工作正常

Question

我在 laravel.log 中有很多错误，每 4-5 秒出现 2 个错误。

这是错误：

"}

这是我的配置：

'redis' => [

        'client' => env('REDIS_CLIENT', 'phpredis'),

        'options' => [
            'cluster' => env('REDIS_CLUSTER', 'redis'),
            'prefix' => env('REDIS_PREFIX', Str::slug(env('APP_NAME', 'laravel'), '_') . '_database_'),
        ],

        'default' => [
            'url' => env('REDIS_URL'),
            'host' => env('REDIS_HOST', '127.0.0.1'),
            'password' => env('REDIS_PASSWORD', null),
            'port' => env('REDIS_PORT', '6379'),
            'database' => env('REDIS_DB', '0'),
        ],

        'cache' => [
            'url' => env('REDIS_URL'),
            'host' => env('REDIS_HOST', '127.0.0.1'),
            'password' => env('REDIS_PASSWORD', null),
            'port' => env('REDIS_PORT', '6379'),
            'database' => env('REDIS_CACHE_DB', '1'),
        ],

    ],

在我的 .env 中：

REDIS_HOST=127.0.0.1
REDIS_PASSWORD=MyPassword
REDIS_PORT=6379

这是堆栈：

• 地平线版本：5.6.0
• Laravel 版本：8.17.0
• PHP版本：7.4.3
• Redis 驱动和版本：predis/phpredis 5.0.7 / 1.1.6
• 数据库驱动程序和版本：Postgres 12

我应该怎么做才能摆脱它们？

您应该禁用 Selinux 或将其设置为许可模式。
