RabbitMQ Server: Error: Host name in Upper-case

This is a small thing, but very annoying.

I didn’t find it in Internet, so decided to blog it here.

My environment: Windows Server 2008 R2 x64; RabbitMQ 2.7.1.

I installed the RabbitMQ Server and tried to interact with it using the rabbitmqctl.bat script. This script requires to use the host name:

>rabbitmqctl –n rabbit@Win2K8R2 status

I was getting the error again and again:

“Error: unable to connect to node rabbit@Win2K8R2: nodedown”



I used the exact string provided me by script (see above in red) -

- nodes and their ports on Win2K8R2:…

and the error text was -

Status of node rabbit@Win2K8R2

When I changed the host name to upper-case, error was gone.

          >rabbitmqctl –n rabbit@WIN2K8R2 status


   Use only upper-case letters in the host name in rabbitmqctl.bat script!
