LogicException: Please make sure the PHP Redis extension is installed and enabled

In case you install Redis with composer require predis/predis, you need to add this line to .env file:

REDIS_CLIENT=predis

Then clear cache by run this command: php artisan optimize:clear

An additional way you can change this line in config/database.php file:

From:

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

To:

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

Then clear cache by run this command: php artisan optimize:clear
