Error installing Windows Service

[Joseph L. Casale]

I am trying to install RabbitMQ on Windows 2019 Server in an environment with several group policy-based restrictions that I assume are interfering with the installation.

When I run the rabbitmq-service.bat file using an elevated terminal, the following error is shown when installing the service:

c:\Program Files\erl-24.0.5\erts-12.0.3\bin\erlsrv: Service RabbitMQ added to the system.

c:\Program Files\erl-24.0.5\erts-12.0.3\bin\erlsrv: Unrecognized option neighbours:.

It appears the actual string in the error is empty as there is nothing between the colon and period.

The resulting Erricson service definition is created with an env multi-line string value that is empty.

Does anyone have an idea which facility may be failing during installation?

Thanks.

Hi,

I have the same problem (with Erlang version 25.2 and RabbitMQ version 3.11.5).
Could anyone solve this error, or understand its reason?

Thanks

Hi  Mátyás,

Please follow these steps exactly and copy everything from your terminal into a file to attach to your next response -

• Open an administrative command prompt
• Change to the RabbitMQ server's sbin directory (most likely C:\Program Files\RabbitMQ Server\rabbitmq*\sbin)
• Run these commands:

.\rabbitmq-service.bat stop

.\rabbitmq-service.bat remove

set

.\rabbitmq-service.bat install

.\rabbitmq-service.bat start

Thanks,

Luke

Hi Luke ,

Thank you for your answer, checking environment variables with "set" helped me to solve my problem.

I have seen earlier the importance of HOMEDRIVE (https://github.com/rabbitmq/rabbitmq-server/discussions/6581#discussioncomment-4420812), but when I checked my env variables in system properties, HOMEDRIVE was not present there, so I didnt understand whats going on. But it was present in cmd after "set", and setting its value (to the same drive on which I wanted to do installation) solved my problem, so I could install RabbitMQ and it operates well since.

Thank you for your help,
Mátyás
