RabbitMQ Windows - Start Server automatically

[Raffaele Garofalo]

We are working with RabbitMQ on a Windows Environment. At the moment I have installed RabbitMQ and it runs as a Service. It starts automatically as shown here:

But if I send a Message or if I query the server here: http://localhost:15672/#/queues the server returns 404

Now, if I open the Shell and hit this command:

rabbitmq-server

The server startup and I can send and receive messages and browse the administration page.

Questions:

• What is the difference then between RabbitMQ Windows Service and RabbitMQ Server?
  
• How can I have the RabbitMQ Server run as a daemon when the PC boot? Is there a command or configuration for that?

There are none: the Windows service just starts RabbitMQ like you did
from the command line.

The Windows service is here for this purpose. So we need to figure out
what's going on with your setup.

After making sure the Windows service is running, could you please post
the output of "rabbitmqctl.bat report"?

So, if the Service is running I get this LOG

What version of RabbitMQ are you using?

Still with the Windows service running, can you retry with
"rabbitmqctl.bat -n rabbit@desktop-4tc0ms7 report"? Ie. with the
hostname as lowercase.

[Raffaele Garofalo]

I have RabbitMQ version 3.6.0 running on different machines.
All with the same problem Windows 2012R2 or Windows 10

So this time the LOG says:

I tried to delete the logs from here:

C:\Users\raffa\AppData\Roaming\RabbitMQ\log

Now, if I stop and start the service, the log folder is empty.

The Windows Service starts as following:

"C:\Program Files\erl7.2.1\erts-7.2.1\bin\erlsrv.exe"

But if I start rabbit using SHELL>rabbitmq-server the LOG is created

So the service may not start at all. I already saw a couple times the
Services window incorrectly saying RabbitMQ was running. It's probably
an issue with RabbitMQ, not Windows, but I couldn't reproduce and fix it
so far.

My hypothesis is: Windows happily uses hostname as lowercase or
uppercase. However, Erlang treats hostnames as case sensitive. In
RabbitMQ 3.6.0, I tried to make sure we used lowercase hostnames, but
apparently, they are cases where this is not the case yet (your node
starts with the uppercase hostname when using the command line). So if
the Mnesia database was created with the uppercase and now, the node
wants to start with a lowercase hostname, it won't work (the reverse is
also true).

Can you try to move C:\Users\raffa\AppData\Roaming\RabbitMQ to another
place (or rename this directory), then try to start the service again?

[Raffaele Garofalo]

I did and now the Folder RabbitMQ doesn't exist anymore, and it has not been re-created when I Started the service.

Also, the Service start from Windows/Services.msc but if I use the Command available from RabbitMQ installation (Start RabbitMQ Service)
the service does not start.

Problem Solved

After further investigations I found out that all RabbitMQ have been installed before configuring the plugin rabbitmq_management and amqp_client so actually the Windows Service was running without doing anything.

I fixed the problem on all my server by doing these steps:

1. Remove RabbitMQ using rabbitmq-service stop, rabbitmq-service remove
   Remember that the CMD must run under Administrator credentials on Windows 10 and Windows Server 2012
2. Install the plugin using rabbitmq-plugins enable rabbitmq_management
3. Start the Service rabbitmq-service start

Also, I restarted Windows and verified that after the reboot the RabbitMQ was up and running.

Again, thanks for your time
