Setting Up Laravel Horizon
Prerequisites:
A Laravel application
Redis server (Ensure your Laravel application's queue connection is set to "redis" in
config/queue.php)
Installation:
- Run the following command in your terminal to install the Horizon package:
Bash
composer require laravel/horizon
- Publish Horizon's configuration files and assets:
Bash
php artisan horizon:install
Configuration:
Horizon uses a single configuration file (config/horizon.php) to define worker behavior and queue settings. Here's a breakdown of some key options:
balance: Set to"auto"to automatically adjust workers based on queue load.supervisor: Enable this for manual intervention capabilities.queues: Define the queues you want Horizon to monitor and manage.
Example Configuration:
PHP
// config/horizon.php
'balance' => 'auto',
'supervisor' => true,
'queues' => [
'default' => [],
'emails' => [],
];
Starting Horizon:
There are two ways to run Horizon:
- In-Process:
This approach starts Horizon alongside your Laravel application using the following command:
Bash
php artisan horizon
- Supervisord:
For a production environment, it's recommended to run Horizon as a separate process using a process supervisor like Supervisord. Refer to the official Laravel documentation for detailed instructions on setting up Supervisord with Horizon.
