Configuration
Redis configuration file: /etc/redis/redis.conf
- bind. Controls which network interfaces Redis listens on.
- protected-mode. Must be disabled if you allow remote access.
- requirepass. Set a password for client authentication.
- maxmemory. Limit RAM usage (for caching use cases).
- appendonly. Enable AOF persistence.
After making any change:
systemctl restart redis-server
Useful Tools and Commands
Redis includes several built-in tools:
redis-cli→ Command-line interface for Redisredis-benchmark→ Benchmarking utilityredis-check-aofandredis-check-rdb→ Validate AOF/RDB persistence filesredis-server→ Manual start of the Redis daemon
Logs and Monitoring
Check logs:
journalctl -u redis-server -f
Monitor activity:
redis-cli monitor
View connected clients:
redis-cli client list
Persistence Modes
Redis supports two persistence options:
- RDB snapshots → Saves database state at intervals (lightweight).
- AOF (Append Only File) → Logs every write (safer but larger).
You can enable both in /etc/redis/redis.conf for durability.
