Redis

Redis is an in-memory data structure store used as a database, cache, and message broker.

​
Installation

sudo stack -redis
Redis requires PHP to be installed. If PHP is not present, you’ll be prompted to install it.

​
What Gets Installed

  • redis-server - Redis server daemon
  • php-redis - PHP extension for Redis

​
Configuration

Redis is automatically configured with optimal settings:
1

Memory Allocation

Webinoly automatically calculates maxmemory based on available RAM:
# Configuration file
/etc/redis/redis.conf

# Memory is set to a percentage of total RAM
maxmemory XXXmb
2

Eviction Policy

Configured with LFU (Least Frequently Used) policy:
maxmemory-policy allkeys-lfu
3

Service Configuration

Redis runs as a systemd service:
sudo systemctl status redis-server

​
Managing Redis

sudo systemctl start redis-server

​
Using Redis

# Connect to Redis CLI
redis-cli

# Test connection
redis-cli ping
# Response: PONG

# Check memory usage
redis-cli INFO memory

# Clear all data
redis-cli FLUSHALL

​
Redis Optimization

# Adjust Redis memory allocation
sudo webinoly -config-set=redis-max-mem:20
sudo stack -php -optim
The value represents percentage of total RAM. Default is calculated automatically.

​
Removing Redis

sudo stack -redis -purge
