Assuming you are on Ubuntu 22/24 and a Laravel php v10/11 application.

Prepare your Laravel app

• Install and configure Laravel Horizon as instructed in docs
• Make sure you can access the Horizon dashboard like - * http://yourapp.com/horizon
• For now; it should show status as inactive on horizon dashboard

Install redis-server (unless you already have it)

We will be using a PPA for latest version

sudo add-apt-repository -y ppa:redislabs/redis
sudo apt-get update
sudo apt-get install -y redis-server

Test if redis-server is working, run

redis-cli

Type ping and hit enter and you will receive PONG in response

Type exit and hit enter to exit from the CLI

Update your Laravel application .env file like this -

QUEUE_CONNECTION=redis

Configure redis server

To make redis-server auto start upon machine reboot,
Edit this file with sudo nano /etc/redis/redis.conf.
Find supervised section and update its value from auto to systemd
Save and exit the conf file.

Now enable the service with this command:

sudo systemctl enable --now redis-server

We are good now with redis server.

Install supervisor

sudo apt install supervisor
sudo service supervisor restart
sudo systemctl enable supervisor

Create supervisor config file for Horizon.

Supervisor keeps its programs' individual files in /etc/supervisor/conf.d

Create a fresh config file for your Laravel application

sudo nano /etc/supervisor/conf.d/laravel-app.conf

and paste these lines into nano editor

program:laravel_horizon]
process_name=%(program_name)s_%(process_num)02d
command=php /home/ubuntu/your-project-folder/artisan horizon

autostart=true
autorestart=true
redirect_stderr=true
user=www-data

stdout_logfile=/home/ubuntu/your-project-folder/storage/horizon.log
stdout_logfile_maxbytes=10MB
logfile_backups=14
stopwaitsecs=3600

You need to update your-project-folder path in file above
Make sure your project's storage folder is writable by www-data (apache) user (same as your web server user).

Save the config file and exit nano.

Now run these commands one by one -

sudo supervisorctl reread
sudo supervisorctl update

Check if our horizon process is running

sudo supervisorctl

You will see process name with status RUNNING, if not; it means you have misconfigured something.

Access your horizon dashboard at http://yourapp.com/horizon, you can see status as active on dashboard.

You can also check horizon status with command

php artisan horizon:status

Make sure to run these commands after each new deployment

php artisan horizon:terminate
php artisan horizon:purge
php artisan queue:restart

If you face any issue, you can restart supervisor service

sudo service supervisor restart

OR - You can restart specific program

sudo supervisorctl restart laravel_horizon
