A Laravel package that extends Laravel Horizon with the ability to restart supervisors across multiple servers, similar to php artisan queue:restart but specifically designed for Horizon workers.

Features

• 🚀 Restart all Horizon supervisors across multiple servers with a single command
• 🔄 Graceful termination of workers similar to queue:restart
• 📦 Automatic service provider registration
• 🎯 Works seamlessly with Horizon's queue distribution
• ⚡ Zero downtime deployments for Horizon workers

Requirements

• PHP 8.2 or higher
• Laravel 11.x or 12.x
• Laravel Horizon 5.x or 6.x

Installation

Install the package via Composer:

composer require huangdijia/laravel-horizon-restart

The service provider will be automatically registered.

Usage

Basic Usage

To restart all Horizon supervisors across all servers:

php artisan horizon:restart

This command will:

1. Discover all running Horizon supervisors
2. Dispatch a restart job to each supervisor's queue
3. Gracefully terminate each supervisor (similar to horizon:terminate)
4. Horizon will automatically restart the supervisors

How It Works

When you run horizon:restart, the package:

1. Discovers Supervisors: Queries the Horizon master supervisor repository to find all active supervisors
2. Dispatches Jobs: Creates a HorizonRestartJob for each supervisor and dispatches it to that supervisor's queue
3. Executes Termination: Each job runs on its respective server and calls horizon:terminate locally
4. Auto Restart: Horizon's process monitoring automatically restarts terminated supervisors

This approach ensures that:

• All servers receive the restart signal
• Workers finish their current jobs before terminating
• No jobs are lost during the restart process
• Each server restarts independently

Use Cases

This package is particularly useful for:

• Multi-Server Deployments: When you have Horizon running on multiple servers and need to restart all of them
• Code Deployments: After deploying new code, restart all workers across all servers
• Configuration Changes: When Horizon configuration changes and all workers need to reload
• Memory Management: Periodic restarts to clear memory leaks or reset worker state

Configuration

The package automatically configures a special supervisor for handling restart jobs. No manual configuration is required.

The restart supervisor is automatically configured with:

• Connection: Uses the same connection as your first Horizon environment
• Queue: Uses Horizon's internal queue name
• Processes: 1 worker to handle restart jobs
• Tries: 3 attempts per job
