Are you stuck with the Redis NOAUTH authentication required error? We’ll help you fix it.
Usually, this error occurs when the Redis has been configured with a password.
At Bobcares, we often receive requests to fix this error as part of our Server Management Services.
Today, let’s have a look at how our Support Engineers fix this error for our customers.
Before getting detailed into the error, let’s have a look at Redis.
Redis is one of the popular in-memory data structure servers. We can use it as a database, cache and so on.
It gains popularity due to its speed and the variety of use cases it enables. But, it often throws some troublesome errors.
Let’s discuss how our Support Engineers fix these errors easily.
How we fix Redis NOAUTH authentication required error?
Usually, this error occurs when the Redis server has a password configured.
If we set the requirepass directive, it will cause the server to require password authentication.
Therefore, we need to issue the AUTH command before any other command while using redis-cli.
Otherwise, we will get the NOAUTH Authentication required error. It is explicitly written in the redis.conf file as follows.
Similarly, we can use the redis-cli with the -a switch. And, following it, we should give our password.
Recently, one of our customers approached us with this error. He tried to connect to his Redis server using the redis-cli command.
But, he got the Redis authentication requirement error. He had Redis version 2.8.4 and server hosted on AWS.
As discussed above, this error usually occurs when Redis has a password set.
Customer checked the Redis config file at etc/redis/redis.conf. But, he could find no password set for Redis.
Our Support Engineers checked the error in detail. And, on checking, we found AWS scanned and connected to all public Redis.
Also, it ran the CONFIG SET REQUIREPASS that caused the error.
So, to fix this error, we restarted Redis to restore the configuration file back to normal. For that, we ran the below command.
sudo service redis-server restart
Also, we can resolve the error by blocking the port 6379 for the public.
