Redis for Queue Processing

Why Redis for Queues#

AcelleMail uses Laravel queues to process campaign sends asynchronously. The default database driver works but creates heavy load on MySQL. Redis is an in-memory data structure store that handles queue operations significantly faster with minimal I/O overhead.

Install Redis on Ubuntu#

sudo apt update && sudo apt install -y redis-server
sudo systemctl enable redis-server
sudo systemctl start redis-server
redis-cli ping   # should return PONG

Configure Laravel to Use Redis#

Edit /home/vbrand/app/.env:

QUEUE_CONNECTION=redis
REDIS_HOST=127.0.0.1
REDIS_PORT=6379
REDIS_PASSWORD=null

Then clear config cache:

php artisan config:cache

Run Queue Workers#

php artisan queue:work redis --sleep=3 --tries=3 --daemon

Use Supervisor to keep workers running:

[program:acellemail-worker]
command=php /home/vbrand/app/artisan queue:work redis --sleep=3 --tries=3
autostart=true
autorestart=true
numprocs=4
user=vbrand

Monitor Redis Queue Depth#

redis-cli llen queues:default
redis-cli info stats | grep total_commands_processed

Install Laravel Horizon for a web-based queue dashboard — it natively supports Redis and gives real-time throughput metrics, failed job tracking, and worker management.
