laravel: 指定redis缓存项的前缀

一，laravel默认会为缓存项添加前缀：

config/database.php中：

    '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'),
            'username' => env('REDIS_USERNAME'),
            'password' => env('REDIS_PASSWORD'),
            'port' => env('REDIS_PORT', '6379'),
            'database' => env('REDIS_DB', '0'),
        ],

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

    ],

例子：

127.0.0.1:6379> keys *
1) "gs_database_ac_13866887788"
2) "a"

 

二，指定前缀：

在配置文件.env中指定REDIS_PREFIX即可,如图

查看效果:已生效

127.0.0.1:6379> keys *
1) "lhdac_13866887788"
2) "a"
