I'm trying to setup Redis replication in order to migrate data from server A to server B. Server A is a master and on server B I'm running:
SLAVEOF <A IP> <A PORT>
But I get the error:
ERR command SLAVEOF is not allowed
Any idea what's causing this error?
Redis Labs' Redis Cloud does not expose replication verbs to its users, as this is entirely managed by the service. You can refer to the FAQ's answer about compatability with the open source comparison as well.
That said, live migrations to our service via standard Redis replication are supported - to achieve that simply contact our support team with your request for further assistance at https://redislabs.com/support

I'm trying to get Celery to connect to an Azure GOV Redis resource.
Found and have tried this answer How to setup Celery to talk ssl to Azure Redis Instance for the connection string.
When I used port 6380 I get a ('time-out') - "ERROR/MainProcess] consumer: Cannot connect to rediss://:#*.redis.cache.usgovcloudapi.net:6380/0: Error while reading from socket: ('timed out',)" ...So I added BROKER_CONNECTION_TIMEOUT and TRANSPORT OPTIONS to try and give me a different result but no change.
My last thought was to try 6379 which I believe is the port that azure suggests... with this I get "Cannot connect to rediss://:#*.redis.cache.usgovcloudapi.net:6379/0: Error 111 connecting to ***.redis.cache.usgovcloudapi.net:6379. ECONNREFUSED"
I know GOV is more restrictive and therefore different than normal Azure so I was wondering if anyone has been able to connect this way successfully, thanks!
We are running redis server on EC2 instance.
i can see in many publications that Redis Server is vulnerable to the log4shell exploit, but can't see any documentation or any official about that.
What should I do in order to protect my redis server instance to be in-vulnerable for this exploit?
Redis Server does not use Java and is therefore not impacted by this vulnerability.
See more here: https://redis.com/security/notice-apache-log4j2-cve-2021-44228/
A smart client for Redis cluster will "take persistent connections to many nodes, will cache hashslot -> node info, and will update the table when they receive a -MOVED error".
I checked numerous documents but can't find a definitive answer on whether Stackexchange.Redis is a smart client. Can anyone advice? Thanks.
I am using Stackexchange.Redis client in my web application to connect to Redis cluster having 6 instances of Redis servers. Stackexchange.Redis client works perfectly with Redis cluster and we did not get -MOVED error.
How to get all connected clients of a redis cluster?

redis has command about client information like CLIENT LIST, check out this page .
you could checkout this page for the command redisson has not supported yet.
The redis cache offered by CloudFoundry has a small capacity, i.e. 16MB.
I know redis has a command "FLUSHALL" which is used to delete all the keys in the cache. How to do the same thing in cloudfoundry?
You can recreate and rebind the service as you wish unless you have any specific configuration that cannot be migrated. (I assume services provisioned by CF.com should be created as the same.)
Also sending FLUSHALL to the redis tunnel should be another option if you have vmc and caldecott gem installed as well as a redis execution locally. Would you mind if you can send the error why you cannot connect to it?
