[rabbitmq-discuss] Starting a Rabbit node remotely using Fabric succeeds yet the node is down

Sun May 20 00:12:53 BST 2012

Hi,
I'm trying to start a stopped node running on a Linux box from a remote 
Windows 7 laptop. The command I send is:

sudo /sbin/service rabbitmq-server start

I get back the success message:

[10.10.3.31] sudo: /sbin/service rabbitmq-server start
[10.10.3.31] out: Starting rabbitmq-server: SUCCESS
[10.10.3.31] out: rabbitmq-server.

But, when I run the rabbitmqctl status command (either through Fabric or 
directly on the Linux box) I get nodedown error:

Status of node 'rabbit at P1-LApp16' ...
Error: unable to connect to node 'rabbit at P1-LApp16': nodedown

DIAGNOSTICS
===========

nodes in question: ['rabbit at P1-LApp16']

hosts, their running nodes and ports:
- P1-LApp16: [{rabbitmqctl16270,33443}]

current node details:
- node name: 'rabbitmqctl16270 at P1-LApp16'
- home dir: /var/lib/rabbitmq
- cookie hash: 95Vy6dqyADwcVrM/tntD6g==

If I start the node directly on the Linux box it works just fine. Once 
the node is started I can send it remote commands to rabbitmqctl via 
Fabric with no problem. I just can't start it remotely. Any idea what's 
going on and how to fix it?

Thanks, Gigi

Here is the output of rabbitmqctl status after I start the node directly 
on the Linuxbox:
