Ok you have some jobs to process in the background using Redis, the first problem that you can get is:

php_network_getaddresses: getaddrinfo for redis failed: nodename nor servname provided, or not known

We are going to tackle this in different steps, first check if you have installed Redis locally, in your terminal run:

Step 1: Install Redis

brew install redis 

Check Redis installation

php -m | grep redis 

You should be able to see that the redis module is installed

Step 2: Set Redis variables

In the .env file set or replace this values:

# Driver configuration CACHE_DRIVER=redis QUEUE_CONNECTION=redis SESSION_DRIVER=redis # Redis setup REDIS_HOST=localhost REDIS_PASSWORD=null REDIS_PORT=6379 

If you are using Herd everything would work, if you are using Herd Pro there is a services section, ONLY if you are using that specific feature this variable should change REDIS_PORT=6138

Step 3: Install Laravel Horizon

In the terminal execute:

composer require laravel/horizon 

And this other command to publish the files:

php artisan horizon:install 

Step 4: Check the connection

In the terminal execute:

php artisan horizon 

You should be able to see the horizon response:

Horizon started successfully.

Step 5: Check Horizon Dashboard

Go to the browser and add to your project url your-project.test/horizon

Then you should be able to see the Horizon dashboard with status: active

Now, you are able to run jobs and monitor them in horizon.

Bonus

Step 6: Set Queues for different Jobs:

You can go to config/horizon.php and set specific queues and even add more supervisors, by default it checks only "defaul" queue, but as it is an array you can add multiple of them:

 'defaults' => [ 'supervisor-1' => [ 'connection' => 'redis', 'queue' => ['default', 'sendEmailInvites'], 

Now you only need to set a specific queue for your emails with something like this:

Mail::to('user@example.com') ->queue((new InvitationEmail($data))->onQueue('sendEmailInvites')); 

You can even go further and set Queue Configuration (not necessary)

Make sure your config/queue.php has the queue configured:

'connections' => [ 'redis' => [ 'driver' => 'redis', // ... other config 'queue' => env('REDIS_QUEUE', 'default'), ], ], // You can also define named queues 'sendEmailInvites' => [ 'driver' => 'redis', 'queue' => 'sendEmailInvites', ],
