Question: What is the default port used by Redis?

Answer

By default, Redis uses port 6379 for client connections. If you want to change this port number to a different value, you can modify the port configuration option in the Redis configuration file (redis.conf). Here's a concise guide on how to change the default port:

  1. Open the Redis Configuration File: On Linux systems, use the following command to open the file in the nano text editor:

    sudo nano /etc/redis/redis.conf
    
  2. Locate the Port Configuration Line: Find the line that specifies the port:

    port 6379
    
  3. Modify the Port Number: Change 6379 to your desired port number (e.g., 6380):

    port 6380
    
  4. Save and Exit: Save the changes and close the editor. In nano, you can do this by pressing Ctrl+O to write the changes and Ctrl+X to exit.

  5. Restart the Redis Server: Apply the changes by restarting the Redis server:

    sudo systemctl restart redis
    

After restarting, clients will need to connect using the new port number (6380 in this example).
