RabbitMQ 3.3.1 can not login with guest/guest - rabbitmq

Question

I have installed the latest version of RabbitMQ on a VPS Debian Linux box. Tried to get login through guest/guest but returned with the message login failed. I did a little research and found that for security reason its prohibited to get login via guest/guest remotely.
I also have tried enabling guest uses on this version to get logged in remotely by creating a rabbitmq.config file manually (because the installation didn't create one) and placing the following entry only
[{rabbit, [{loopback_users, []}]}].
after restart the rabbitmq with the following command.
invoke-rc.d rabbitmq-server stop -- to stop
invoke-rc.d rabbitmq-server start -- to start
It still doesn't logged me in with guest/guest. I also have tried installing RabbitMQ on Windows VPS and tried to get log in via guest/guest through localhost but again i get the same message login failed.
Also provide me a source where I could try installing the old version of RabbitMQ that does support logging remotely via guest/guest.

Answer 1

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,
Add a new/fresh user, say user test and password test:
rabbitmqctl add_user test test
Give administrative access to the new user:
rabbitmqctl set_user_tags test administrator
Set permission to newly created user:
rabbitmqctl set_permissions -p / test ".*" ".*" ".*"
That's it, enjoy :)

I tried on Debian the same configuration with the following steps:
Installed RabbitMQ.
Enabled the web-management plug-in (not necessary).
When I tried to login I had the same error:
So I created a rabbitmq.config file (classic configuration file) inside the /etc/rabbitmq directory with the following content (notice the final dot):
[{rabbit, [{loopback_users, []}]}].
Alternatively, one can create instead a rabbitmq.conf file (new configuration file) inside the same directory with the following content:
loopback_users = none
Then I executed the invoke-rc.d rabbitmq-server start command and both the console and the Java client were able to connect using the guest/guest credentials:
So I think you have some other problem if this procedure doesn't work. For example your RabbitMQ might be unable to read the configuration file if for some reason you have changed the RABBITMQ_CONFIG_FILE environment variable.

This is a new features since the version 3.3.0. You can only login using guest/guest on localhost. For logging from other machines or on ip you'll have to create users and assign the permissions. This can be done as follows:
rabbitmqctl add_user test test
rabbitmqctl set_user_tags test administrator
rabbitmqctl set_permissions -p / test ".*" ".*" ".*"

Answer 4

Adding the below line in the config file and restarting the server worked for me. Kindly try in your setup.
loopback_users.guest = false
I got this line from the example RabbitMQ config file from Github as linked here.

Answer 5

notice: check your PORT is 15672 ! (version > 3.3 ) if 5672 not works
First of all, check the "choosen answer above":
rabbitmqctl add_user test test
rabbitmqctl set_user_tags test administrator
rabbitmqctl set_permissions -p / test ".*" ".*" ".*"
and if still can't make connection work, check if your port is correct!
for me, this command works:
$ rabbitmqadmin -H 10.140.0.2 -P 15672 -u test -p test list vhosts
+------+----------+
| name | messages |
+------+----------+
| / | |
+------+----------+
for the completed ports , check this:
What ports does RabbitMQ use?
to verify your rabbit mq server, check this: Verify version of rabbitmq
p.s.
For me, after I created the "test" user and run set_user_tags, set_permissions , I can't connect to rabbitmq via port 5672. but I can connect via 15672.
However, port 15672 always gives me a "blank response". and my code stop working.
so about 5 minutes later, I switched to 5672, everything worked!
Very wired problem. I have no time to dig deeper. so I wrote it down here for someone meeting the same problems.

for other guys which use Ansible for RabbitMQ provisioning, what I missed for rabbitmq_user module was tags: administrator
here is my working Ansible configuration to recreate "guest" user (for development environment purpose, don't do that in production environment):
- name: Create RabbitMQ user "guest"
become: yes
rabbitmq_user:
user: guest
password: guest
vhost: /
configure_priv: .*
read_priv: .*
write_priv: .*
tags: administrator
force: yes # recreate existing user
state: present
and I also had to setup a file /etc/rabbitmq/rabbitmq.config containing the following:
[{rabbit, [{loopback_users, []}]}].
in order to be able to log using "guest"/"guest" from outside of localhost

#Create rabbitmq.conf file with
rabbitmq.conf
loopback_users = none
Dockerfile:
FROM rabbitmq:3.7-management
#Rabbitmq config
COPY rabbitmq.conf /etc/rabbitmq/rabbitmq.conf
#Install vim (edit file)
RUN ["apt-get", "update"]
RUN ["apt-get", "-y", "install", "vim"]
#Enable plugins rabbitmq
RUN rabbitmq-plugins enable --offline rabbitmq_mqtt rabbitmq_federation_management rabbitmq_stomp
Run:
$ docker build -t my-rabbitmq-image .
$ docker run -d --hostname my-rabbit --name some-rabbit -p 8080:15672 my-rabbitmq-image
Check that the rabbitmq.conf file has been copied correctly.
$ docker exec -it my_container_id /bin/bash
$ vim /etc/rabbitmq/rabbitmq.conf

Answer 8

I had the same problem. I tried what was suggested by Gas and ran "invoke-rc.d rabbitmq-server start" it didn't start. I tried to reboot the server and the webui worked with the guest user. Maybe after adding the rabbitmq.config file, something else also needed to started.
I used rabbitmq version 3.5.3.
One more thing to note: if you're using AWS instance then you need to open inbound port 15672. (The port for RabbitMQ versions prior to 3.0 is 55672.).

Answer 9

Students and I stared at this problem for an hour. Be sure you've named your files correctly. In the /etc/rabbitmq directory, there are two distinct files. There is an /etc/rabbitmq/rabbitmq.config file which you should edit to get the loopback users as described, but there is another file called rabbitmq-env.conf file. Many folks were using tab completion and just adding "ig", which isn't the right file. Double check!

Answer 10

sometimes you don't need the comma , which is there in the configuration file by default , if nothing else is configured below rabbit tag , while starting broker
we will get a crash
like
{loopback_users, []} , I spend many times hours forgetting this and later removing the comma , it is applicable for all other configurations including SSL

Answer 11

Try restart your rabbitmq and login again, for me work.

Answer 12

For a slightly different use, but might be useful for anyone dealing with accessing the API for monitoring purposes:
I can confirm the answer given by #Oliboy50 works well, however make sure you enable it for each vhost you want the user to be able to monitor, such as:
permissions:
- vhost: "{{item.name}}"
configure_priv: .*
write_priv: .*
read_priv: .*
state: present
tags: management
with_items: "{{user_system_users}}"
With this loop I was able to get past the "401 Unauthorized" error when using the API for any vhost.

Answer 13

By default, the guest user is prohibited from connecting from remote hosts; it can only connect over a loopback interface (i.e. localhost). This applies to connections regardless of the protocol. Any other users will not (by default) be restricted in this way.
It is possible to allow the guest user to connect from a remote host
by setting the loopback_users configuration to none
# DANGER ZONE!
#
# allowing remote connections for default user is highly discouraged
# as it dramatically decreases the security of the system. Delete the user
# instead and create a new one with generated secure credentials.
loopback_users = none
Or, in the classic config file format (rabbitmq.config):
%% DANGER ZONE!
%%
%% Allowing remote connections for default user is highly discouraged
%% as it dramatically decreases the security of the system. Delete the user
%% instead and create a new one with generated secure credentials.
[{rabbit, [{loopback_users, []}]}].
See at "guest" user can only connect from localhost
TIP: It is advisable to delete the guest user or at least change its password to reasonably secure generated value that won't be known to the public.

Answer 14

If you will check the log file under info report you will get this.
`config file(s) : /etc/rabbitmq/rabbitmq.config (not found)`.
Change the config file permission using below command then login using guest , it will work
sudo chmod 777 /etc/rabbitmq/rabbitmq.config
