I'm new to RabbitMQ and docker. I'm running a Springboot app and I have a docker container that is running the management console on 15672. I'm able to get to that in my browser just fine, but I cannot connect to RabbitMQ when I start the application using this in my yml file:
rabbitmq:
username: test
password: test
host: localhost
port: 5672
test is a user I created with admin permissions same as guest.
When I change the user/password to guest, it tries over and over to connect to 5672 and finally times out. test/test just fails fast with this error:
Rabbit health check failed
org.springframework.amqp.AmqpConnectException: java.net.ConnectException: Connection refused (Connection refused)
at org.springframework.amqp.rabbit.support.RabbitExceptionTranslator.convertRabbitAccessException(RabbitExceptionTranslator.java:61) ~[spring-rabbit-2.2.6.RELEASE.jar:2.2.6.RELEASE]
Any advice for a newbie would be greatly appreciated.
I'm expecting to connect to RabbitMQ using test/test on port 5672. But I must have something configured incorrectly.

Configuring a ELK stack version 8.1, based on two virtual machine which both run Oracle linux 8. I need to send logs from a VM to the other using rsyslog. On the recieving machine logs will be acquired using FileBeat. The file rsyslog.conf has been configured on the sending machine, adding target machine parameters. The file filebeat.yml has been configured to recieve logs from rsyslog like this:
- type: syslog
enabled: true
format: auto
protocol.tcp:
host: "X.X.X.X:10514"
The firewalld on the receiving machine has been configured opening the port 10514.
Since the reboot after configuration, the only thing I can get is the error:
cannot connect to X.X.X.X:10514: Connection refused
How can I solve this problem?
This spring guide on messaging with rabbitmq does not talk about the host port configurations. I followed the same and added these properties to application.properties to connect to rabbitmq broker installed on GCP
spring:
rabbitmq:
host: XXX.XXX.XXX.XX
port: 5672
username: user
password: bitnami
virtual-host: /
While running the app I am getting timeout exception while connecting to rabbitmq

Tried the following but still same error:
Opened up tcp:5672 through GCP firewall configuration
Changed the rabbitmq config at /opt/bitnami/rabbitmq/etc/rabbitmq/rabbitmq.config to change the allowed ips from localhost (127.0.0.1) to 0.0.0.0
{
rabbit,
[{tcp_listeners, [{"0.0.0.0", 5672}, {"::", 5672}]},
{default_vhost, <<"/">>},
{default_user, <<"user">>},
{default_pass, <<"bitnami">>},
{default_permissions, [<<".*">>, <<".*">>, <<".*">>]}
}
What could be the problem here ?
Update
I have installed rabbitmq locally and everything works fine.
I doubt if the updates to config file is actually not getting reflected properly. This is how I did it.
updated the rabbitmq.config
rabbitmqctl stop_app
rabbitmqctl start_app
But still I see some difference under the 'Ports and contexts' section in the UI
localhost
gcp
Any pointers ? Or is it all looking fine and the problem is something different, like with GCP setup or something ?
After telnet-ing to the port and checking the port config through the GCP console I figured out that I did a mistake in setting the right tag name to the instance where I installed rabbitmq.
Please do verify that the 'target tag' mentioned in your firewall rule is indeed mapped to the vm instance where rabbitmq is installed
Otherwise the config mentioned in the question is enough to make it work from a remote client
I have recently instaled glassfish-4.1. When i try to establish connection with the localhost page or to glassfish (127.0.0.1 or 127.0.0.1:8080) - i get an error reply. When I checked the Netstat- an command on my cmd - I couldnt find either ports in the log. I get "Error connection refused" What should i do?
I want to use jvisualvm's remote functionality to see live stats of a remote JVM.
I've started the jvisualvm from my windows machine but I don't know how to configure the remote connection.
On the remote machine (OS: Redhat Linux), tomcat is started with below jmx parameters:
-Dcom.sun.management.jmxremote"
-Dcom.sun.management.jmxremote.port=3030"
-Dcom.sun.management.jmxremote.authenticate=false"
-Dcom.sun.management.jmxremote.ssl=false"
netstat -lnp| grep 3030
tcp 0 0 0.0.0.0:3030 0.0.0.0:* LISTEN 30728/java
ssh connection is open to remote server and I tunneled the remote port 3030 on a certain local port but when I create new jmx connection (localhost:localport) in jvisualvm I get the below error
Cannot connect to localhost:10000 using service:jmx:rmi:///jndi/rmi://localhost:10000/jmxrmi
Can someone help me to create the connection?
First of all if you are making a remote connection, localhost connection doesn't make sense.
You need to start jstatd on the remote machine. For this purpose create a jstatd.all.policy file in the home directory of your remote machine and add the following lines:
grant codebase "file:${java.home}/../lib/tools.jar" {
permission java.security.AllPermission;
};
Then on the command line of your remote machine you will type ' jstatd -J-Djava.security.policy=jstatd.all.policy -J-Djava.rmi.server.hostname={Your Ip address} '
Once jstatd service start on the remote machine you basically add the remote connection Ip address connection on the jvisualVM UI using add remote host.
The Oracle documents for JvisualVM can be referred at https://docs.oracle.com/javase/8/docs/technotes/guides/visualvm/applications_remote.html but it is really confusing to understand jstatd steps.
I am trying to connect to RabbitMQ with EasyNetQ.
RabbitMQ is on remote VM.
_rabbitBus = RabbitHutch.CreateBus(
string.Format("host={0};virtualhost={1}",
_hostSettings.Host, _hostSettings.VHost),
x => x.Register<IEasyNetQLogger>(l => _logger));
_rabbitBus.Subscribe<Message>(_topic, ReceiveMessage, m => m.WithTopic(_topic));
I get a TimeoutException The operation requested on PersistentChannel timed out..
Remote VM is replying to pings, ports 5672 and 15672 are opened (checked with nmap).
RabbitMQ management can be accessed from my host.
Also, if RabbitMQ is run on my local machine, it works fine.
I've tried connecting to RabbitMQ installed on my computer from other pc's in LAN, and it also works.
I've come to an assumption, that it's related to the fact it's on a virtual machine, and maybe there's something wrong in connection. But again, Rabbit's web management works fine.
Also tested on EasyNetQ Test application - works on localhost, but not on remote.
Output as following:
DEBUG: Trying to connect
ERROR: Failed to connect to Broker: '192.168.0.13', Port: 5672 VHost: '/'.
ExceptionMessage: 'None of the specified endpoints were reachable'
ERROR: Failed to connected to any Broker. Retrying in 5000 ms
EasyNetQ v0.28.4.242
As Mike suggested i had this and then checked the permissions. "guest" user can only connect via localhost (see RabbitMQ Access Control.) Try adding a user with permissions using the management interface and then connect as below
var _bus = RabbitHutch.CreateBus(string.Format("host={0};virtualhost={1};username={2};password={3}",
_hostSettings.Host, _hostSettings.VHost, _hostSettings.UserName, _hostSettings.Password));
Did you check your credentials. The default username and password is 'guest' and 'guest'. The error message is not very helpful. You get 'None of the specified endpoints were reachable' if there's an authentication error as well
