尽管设置了redis进行缓存，Laravel仍然使用数据库表进行缓存

问题描述 投票：0回答：1

从文档中我为缓存设置了redis。但是每当我尝试到达任何端点时，都会出现错误，因为 ebing 无法在数据库中找到表缓存。我只想使用 redis 而不是数据库，但我不确定配置文件中还缺少什么。

这些是我拥有的文件。例如在 config/database

<?php declare(strict_types=1);
return [
    'default' =>'mysql',
    'connections' => [
        'mysql' => [ ... ],
    ],
    'redis' => [
        'client' => env('REDIS_CLIENT', 'predis'),
        'default' => [
            'url' => env('REDIS_URL'),
            'host' => env('REDIS_HOST', '127.0.0.1'),
            'password' => env('REDIS_PASSWORD'),
            'port' => '6379'
        ],
        'cache' => [
            'url' => env('REDIS_URL'),
            'host' => env('REDIS_HOST', '127.0.0.1'),
            'password' => env('REDIS_PASSWORD'),
            'port' => '6379',
        ],
    ],
];

在 config/cache.php 我有以下内容：

<?php declare(strict_types=1);

return [
    'default' => env('CACHE_STORE', 'redis'),
    "driver" => env("CACHE_DRIVER", "redis"),
    'stores' => [
        'redis' => [
            'driver' => 'redis',
            'connection' => env('REDIS_CACHE_CONNECTION', 'cache'),
            'lock_connection' => env('REDIS_CACHE_LOCK_CONNECTION', 'redis'),
        ],
    ],
    'prefix' => env('CACHE_PREFIX', 'MYT')
];

每当我尝试到达任何端点时，都会收到以下错误

该问题很可能是由 Laravel 的 维护模式 引起的。它使用专用配置设置来确定在检查维护模式当前是否处于活动状态时查询哪个存储。

您可以在 

maintenance
配置文件中的 
app.php
键下找到这些设置：

    /*
    |--------------------------------------------------------------------------
    | Maintenance Mode Driver
    |--------------------------------------------------------------------------
    |
    | These configuration options determine the driver used to determine and
    | manage Laravel's "maintenance mode" status. The "cache" driver will
    | allow maintenance mode to be controlled across multiple machines.
    |
    | Supported drivers: "file", "cache"
    |
    */

    'maintenance' => [
        'driver' => env('APP_MAINTENANCE_DRIVER', 'file'),
        'store' => env('APP_MAINTENANCE_STORE', 'database'),
    ],

您想要将 

cache
设置为维护模式 driver 并将 
redis
设置为 store，如下所示：

    'maintenance' => [
        'driver' => env('APP_MAINTENANCE_DRIVER', 'cache'),
        'store' => env('APP_MAINTENANCE_STORE', 'redis'),
    ],

或者，您可以使用环境变量来设置这两个值：

APP_MAINTENANCE_DRIVER=cache
APP_MAINTENANCE_STORE=redis

更改设置后运行

php artisan config:clear
命令，问题应该得到解决。
