I've installed RabbitMQ 3.5.5 on Windows Server 2012 as a service by first installing Erlang (32 bit) and then following the RabbitMQ manual install instructions (https://www.rabbitmq.com/install-windows-manual.html)
The Windows service starts up fine, but nothing can connect.
When I run rabbitmq_server-3.5.5\sbin\rabbitmqctl.bat status I get the following output:
rabbit@XXXXXXXX:
- connected to epmd (port 4369) on XXXXXXXX
- epmd reports node 'rabbit' running on port 25672
- TCP connection succeeded but Erlang distribution failed
- suggestion: hostname mismatch?
- suggestion: is the cookie set correctly?
- suggestion: is the Erlang distribution using TLS?
current node details:
- node name: 'rabbitmq-cli-1444@XXXXXXXX'
- home dir: C:\Users\userxxxx
- cookie hash: XDarCC/CmuhQpUEo95dj8g==
From the output and from netstat I can see that rabbit is running on port 4369.
I can start the server manually using rabbitmq-server.bat and everything works.
I can't find any additional cookies floating around except for the one in my user directory (C:\Users\userxxxx).
Does anyone have any ideas?
This a typo.
Are you sure that you don't have .erlang.cookie inside c:\windows . Have you copied the file as described here?
Copy the file .erlang.cookie manually from %SystemRoot% to %HOMEDRIVE%%HOMEPATH%.
