RabbitMQ failed to start, TCP connection succeeded but Erlang distribution failed

Question

I\'m a new one just start to learn and install RabbitMQ on Windows System.

I install Erlang VM and RabbitMQ in custom folder, not default folder (Both of them).

Answer 1

Just adding my experience if it helps others down the line.

I wrote a Powershell .ps1 script to install and configure RabbitMQ which would be used as one of the stept to provision a server with Packer.

I wrote the code on a fresh AWS W2016 Server build. It worked fine when run on the box (as administrator, from an admin PS console) but when the same code was moved over to the Packer build server, it would fall over when doing the rabbitmqctl.bat configuration steps via packer, despite both using (as far as I can tell) Administrator to run the scripts.

So this worked on the coding box:

$pathvargs = {cmd.exe /c "rabbitmqctl.bat" add_user Username Password}
Invoke-Command -ScriptBlock $pathvargs
$pathvargs = {cmd.exe /c "rabbitmqctl.bat" set_user_tags User administrator}
Invoke-Command -ScriptBlock $pathvargs
$pathvargs = {cmd.exe /c "rabbitmqctl.bat" set_permissions -p "/" User "^User-.*" ".*" ".*"}
Invoke-Command -ScriptBlock $pathvargs
Write-Host "Did RabbitMQ"

But I had to prelude this with...

copy "C:\Windows\system32\config\systemprofile\.erlang.cookie" "C:\Program Files\RabbitMQ Server\rabbitmq_server-3.7.17\sbin\.erlang.cookie"
copy "C:\Windows\system32\config\systemprofile\.erlang.cookie" $env:userprofile\.erlang.cookie -force

... On the Packer box.

I am guessing there is some context issue going on but I'm using

"winrm_username":       "Administrator",

in the Packer builders block, so I thought this would suffice.

TL;DR - Use the Cookie even though it works without it in some instances.
