The “NOAUTH Authentication required” error message typically occurs when Redis requires authentication before allowing access to its commands. By default, Redis does not enable authentication, so this error can arise if you’re trying to access a Redis instance that has authentication enabled.
To resolve this issue, you need to provide the correct authentication credentials in your Redis client. You can do this by using the AUTH command followed by the password. For example:
AUTH your_password
Replace your_password with the actual password set for your Redis instance.
If you’re connecting to Redis programmatically, make sure to include the authentication step in your code before executing any commands. Here’s an example using the popular redis-py library in Python:
import redis
# Connect to Redis and authenticate
r = redis.Redis(host='localhost', port=6379)
r.auth('your_password')
# Now you can execute other commands
r.set('key', 'value')
Remember to replace 'your_password' with the actual password configured for your Redis instance.
