[rabbitmq-discuss] Problems starting RabbitMQ as a windows service.

[Richard Hudson]

Hi,

We've recently moved over to using RabbitMQ from MSMQ and have generally had
success in running RabbitMQ as a windows service on a number of different
OSes (XP, Windows2003, Windows 7).

However, we've come across a strange problem when starting up a rabbitMQ
service on Windows 2003 SP2 on a VM, using RabbitMQ 2.51 and Erlang 5.8.4.
Not sure if the VM aspect is relevant.

Using the rabbitmq-service.bat to install the service, the service (running
under the local system account) starts and stops pretty much straight away.
Here's the output from rabbitMQ.debug

The port is definitely not in use. Nor is there a firewall enabled.

Having looked though the archives we've tried passing in sname and name
arguments to erl.exe with no luck.

The interesting thing is that we can get RabbitMQ to run as an application
on this box, using the standard rabbitmq-server.bat.

After a bit of messing around we also found that if we set
HKEY_LOCAL_MACHINE\SOFTWARE\Ericsson\Erlang\ErlSrv\1.1\RabbitMQ\Machine
to point to D:\Program Files\erl5.8.4\bin\erl.exe rather than D:\Program
Files\erl5.8.4\erts-5.8.4\bin\erl.exe then the service also runs. Queues get
created and we can successfully publish/subscribe to queues .

Does anyone have any thoughts on why the standard service install would fail
but the application and modified install seem to work fine.

How safe is it to use erl.exe from erl5.8.4\bin\erl.exe rather than
erl5.8.4\erts-5.8.4\bin\erl.exe?
i.e is this an acceptable workaround.

Thanks in advance for any help.

Regards

Richard
