```

#### **2. Managing Redis Service**

```bash theme={null}
sudo systemctl start redis    # Start Redis

```

#### **3. Configuring Redis**

Edit Redis configuration file:

```bash theme={null}
sudo nano /etc/redis/redis.conf
```

* Set a password: `requirepass yourpassword`
* Change the bind address if needed.

Restart Redis after changes:

```bash theme={null}
sudo systemctl restart redis
```

#### **4. Flushing Redis Database**

```bash theme={null}
redis-cli FLUSHALL    # Flush all databases
redis-cli FLUSHDB     # Flush the current database
```

#### **5. Basic Redis Commands**

```bash theme={null}
redis-cli SET key "value"   # Set a key-value pair
redis-cli GET key           # Retrieve value of a key
redis-cli DEL key           # Delete a key
redis-cli KEYS *            # List all keys
redis-cli EXISTS key        # Check if a key exists
redis-cli TTL key           # Check time-to-live for a key
redis-cli INCR counter      # Increment a key's value
redis-cli DECR counter      # Decrement a key's value
```
