Fix commond Laravel Horizon issues

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('[e-mail]')
    ->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',
],
