How to setup RabbitMQ cluster with AWS EC2

Question

Followed this article https://medium.com/@vipin.pratap18/rabbitmq-cluster-on-aws-ec2-with-high-availability-1bcd3f8a6404

But while doing sudo rabbitmqctl join_cluster rabbit@

facing issue

DIAGNOSTICS

attempted to contact: [rabbit@rabbitmqnode1]

rabbit@rabbitmqnode1:

• connected to epmd (port 4369) on rabbitmqnode1

• epmd reports node 'rabbit' uses port 25672 for inter-node and CLI tool traffic

• TCP connection succeeded but Erlang distribution failed

• Node name (or hostname) mismatch: node "rabbit@ip-xxxxx" believes its node name is not "rabbit@ip-xxxxx" but something else. All nodes and CLI tools must refer to node "rabbit@ip-10-0-1-122" using the same name the node itself uses (see its logs to find out what it is)

Answer 1

I solved it by following the logs itself

it clearly says "CLI tools must refer to node "rabbit@ip-10-0-x-xxx" using the same name the node itself uses"

while passing the cluster node name i was doing it wrong NOTE: added hostname from cat /etc/hosts

did like below sudo rabbitmqctl join_cluster rabbit@ip-10-0-x-yyy

and it worked suucessfull message "Clustering node rabbit@ip-10-0-x-xxx with rabbit@ip-10-0-x-yyy"
