Error using rabbitmq-server

[duricu vlad]

Hey, I am using rabbitmq 3.7.4, and when I try to start the server with the command rammitmq-server start it gave me the following error:

Error description:

What should I do with this error?

[Michael Klishin]

RabbitMQ tries to run a subprocess to collect the number of file handles used or similar ("external stats")

but that fails due to

> C:\\windows\\system32\\cmd.exe;C:\\Program Files\\Java\\jdk1.8.0_131\\bin;C:\\Program Files\\nodejs /c handle.exe /accepteula -s -p 4920 2> nul

not being a file. I strongly suspect there is an issue with environment variable quoting or separation here, since RabbitMQ never

calls JDK or Node.js binaries (why would it?). It does try to call handle.exe if that's available to retrieve some system stats.

So I should modifie the system variables, to point for the right .exe?

I'd start by double checking that the PATH variable and ERLANG_HOME (if applicable) are

correct.

We cannot suggest much more without knowing how exactly RabbitMQ and Erlang were installed on your system

and what kind of environments variables were set or modified.

Hey, I have checked the ERLANG_HOME = " C:\Program Files\erl9.3" (DEFAULT INSTALL PATH)path and it is the wright one. I found a post where it says that I should remove the rabbitmq-service and I must install it again, but when I run the command as the administrator rabbitmq-service remove it gave me the next error:

C:\Program Files\RabbitMQ Server\rabbitmq_server-3.7.4\sbin>rabbitmq-service.bat remove

C:\Program Files\erl9.3\erts-9.3\bin\erlsrv: Unable to remove service (not enough privileges?)

Error: The handle is invalid.

And an interesting fact is that rabbitmq doesn't show in the services and regedit, after I reinstall it.

Hey, do not  bother to answer my question, I have finally succeeded to install it.

Hi Duricu,

May I ask what was the root cause?

I do not know exactly what was the problem. I downloaded again the rabbitMQ, but the second time was from GitHub. I think it wasn't installed properly, even though it didn't give me an error. I run the exe file (re)install, I removed and install again the service, I added the management plugins and worked. The paths from the system environment wear correct, it wasn't a problem here. And also gave ma an error about the management-path-envirent of erlang, these I didn't know what to solve it, but finally worked.
