rabbitMQ guest login failed - authentication

Question

I have setted up rabbitMQ and its management plubin in windows,
I found rabbitmq.config file with "EXAMPLE FILE" type in the path of
" ...AppData\Roaming\RabbitMQ " and " C:\Program Files (x86)\RabbitMQ Server\rabbitmq_server-3.3.1\etc "
I add the line {loopback_users, []} into this rabbitmq.config file, and restart the windows service, but still can't login from another computer with guest/guest
Am I editing the wrong config file?
Here is some relevant discussion:

Answer 1

RabbitMQ service can't read the configuration file, this is the problem. So, your configuration file is not loaded.
The path "..AppData\Roaming\RabbitMQ" is valid only if you execute rabbitmq-server.bat from the command prompt and not if you execute a service.
In order to work with Windows Service you have to configure the environment variable RABBITMQ_CONFIG_FILE in windows.
Open Control Panel > System > Advanced > Environment Variables and then add:
RABBITMQ_CONFIG_FILE
path_your_configuration_file
as:
Then you have to uninstall and re-install rabbitmq and it works.
Please read this discussion
I tried on windows7 with rabbitmq 3.3.1, it works corretly using guest/guest.
My configuration file is:
[{, [{loopback_users, []}]}].

A combination of the prior post and the comment from Jon Egerton was key to getting my Windows configuration working for the guest account remotely. Here are steps I took:
Set an environment variable: RABBITMQ_BASE (I set mine to
c:\RabbitMQData)
Create the directory and create the rabbitmq.config file as explained in the previous post.
Uninstall RabbitMQ (As mentioned already, don’t skip this step. Stopping and starting RabbitMQ won’t do the trick)
Reinstall RabbitMQ and verify the RabbitMQ Server service started.
Verify that the directory specified by RABBITMQ_BASE contains the db and log sub-directories.
Install the RabbitMQ_Management plug-in from the command line.
Verify that you can now logon as the guest account using the host’s IP address or host name.
