# Enter Redis CLI
docker exec -it redis redis-cli

Common redis.conf Settings ​

bash
# redis.conf key configuration items

# === Network ===

port 6379               # Listening port
protected-mode yes      # Protection mode, set to no for external access and configure password
tcp-backlog 511         # TCP connection queue length
timeout 0               # Client idle timeout (seconds), 0 means never timeout

# === Security ===
requirepass your_strong_password  # Set access password
rename-command FLUSHALL ""        # Disable dangerous commands

# === Persistence ===

💡 Tip: After modifying configuration, you need to restart Redis or run CONFIG SET parameter value for hot reload. Use CONFIG REWRITE to persist runtime changes to the configuration file.
