How to setup redis on a Linux vps

To set up Redis on a Linux VPS, follow these steps:

1. Update your system packages:

  ```
  sudo apt update
  ```

2. Install Redis:

  ```
  sudo apt install redis
  ```

3. Verify the installation:

  ```
  redis-cli --version
  ```

4. Check Redis service status:

  ```
  sudo systemctl status redis
  ```

5. If not running, start Redis:

  ```
  sudo systemctl start redis
  ```

6. Enable Redis to start on boot:

  ```
  sudo systemctl enable redis
  ```

7. Configure Redis by editing the configuration file:

  ```
  sudo nano /etc/redis/redis.conf
  ```

8. Set important configuration parameters:

  - Bind address: `bind 127.0.0.1`
  - Protected mode: `protected-mode yes`
  - Set max memory: `maxmemory 256mb`

9. Save the configuration and restart Redis:

  ```
  sudo systemctl restart redis
  ```

10. Test the Redis connection:

   ```
   redis-cli ping
   ```
   If successful, you should see "PONG" as the response.

For enhanced security, consider renaming or deactivating dangerous Redis commands and implementing regular backups and log auditing[1].
