How to access RabbitMq publicly

It's new features since the version 3.3.0 http://www.rabbitmq.com/release-notes/README-3.3.0.txt

server
------

...
25603 prevent access using the default guest/guest credentials except via
      localhost.

If you want enable the guest user read this or this RabbitMQ 3.3.1 can not login with guest/guest

# remove guest from loopback_users in rabbitmq.config like this
[{rabbit, [{loopback_users, []}]}].
# It is danger for default user and default password for remote access
# better to change password 
rabbitmqctl  change_password guest NEWPASSWORD

If you want create a new user with admin grants:

rabbitmqctl add_user test test
rabbitmqctl set_user_tags test administrator
rabbitmqctl set_permissions -p / test ".*" ".*" ".*"

Now you can access using test test.

I had the same Problem..

I installed RabbitMQ and Enabled Web Interface also but still couldn't sign in with any user i newly created, this is because you need to be administrator to access this.

Do not create any config file and mess with it..

This is what i did then,

1. Add a new/fresh user, say user test and password test:

   rabbitmqctl add_user test test
   

2. Give administrative access to the new user:

   rabbitmqctl set_user_tags test administrator
   

3. Set permission to newly created user:

   rabbitmqctl set_permissions -p / test ".*" ".*" ".*"
   

That's it, enjoy :)
