I installed RabbitMQ server on OS X, and started it on command line. Now, it is not obvious that how I should stop it from running? After I did:
sudo rabbitmq-server -detached
I get:
Activating RabbitMQ plugins ...
0 plugins activated:
That was it. How should I properly shut it down? In the document, it mentions using rabbitmqctl(1), but it's not clear to me what that means. Thanks.
Edit: As per comment below, this is what I get for running sudo rabbitmqctl stop:
(project_env)mlstr-1:Package mlstr$ sudo rabbitmqctl stop

DIAGNOSTICS
===========
nodes in question: [rabbit#h002]
hosts, their running nodes and ports:
- h002: [{rabbit,62428},{rabbitmqctl7069,64735}]
current node details:

- home dir: /opt/local/var/lib/rabbitmq
- cookie hash: q7VU0JjCd0VG7jOEF9Hf/g==
Why is there still a 'current node'? I have not run any client program but only the RabbitMQ server, does that mean a server is still running?
It turns out that it is related to permissions. Somehow my rabbitmq server was started with user 'rabbitmq' (which is strange), so that I had to do
sudo -u rabbitmq rabbitmqctl stop
In my dev environment where I keep it running all the time, I use:
launchctl unload ~/Library/LaunchAgents/homebrew.mxcl.rabbitmq.plist
and to start it
launchctl load ~/Library/LaunchAgents/homebrew.mxcl.rabbitmq.plist
Even easier....
brew services stop rabbitmq
brew services start rabbitmq
Use rabbitmqctl stop to stop any node. If you need to specify the node giving you trouble, add the -n rabbit#[hostname] option.
You can also use the shortcut RabbitMQ Service - stop if you don't like the commands
stop
sudo systemctl stop rabbitmq-server
start
sudo systemctl start rabbitmq-server
For Windows, use PowerShell as Admin, then run
.\rabbitmq-service.bat stop
stop Stop the service. The service must be running for this command to have any effect.

For OP's answer above,
It turns out that it is related to permissions.
I have no knowledge on this.

I've searched for port to see that if it's in use or not and I used lsof -i :25672 and I get nothing.
I don't know too much about these things so if you need anything please tell me.
Try:
sudo lsof -i :25672
sudo kill <PID>
sudo rabbitmq-server
Where <PID> is the process ID that is occupying port 25672
I have encountered this issue. I figured out that this issue is coming because the rabbitmq-server is already running on the machine.
I have used the following command
rabbitmqctl.bat status to know the status of the rabbitmq-server. This helped me to know if the server is up or down.
If it is up, this could the reason you are getting the error that you have specified in your post.
You can issue the following command to make the server down
rabbitmqctl.bat stop
Now you can try starting the rabbitmq-server by issuing the following command
rabbitmq-server start
Note that I am using Windows. And I have executed these commands by pointing the command prompt to C:\Program Files\RabbitMQ\rabbitmq_server-3.8.14\sbin as my rabbitmq installation directory is C:\Program Files\RabbitMQ\rabbitmq_server-3.8.14.
I have encountered this before. Here is what caused it and how I fixed it:
This is one of those commands which requires the magic word sudo (i.e it needs a superuser privilege).
If you forget to add sudo to the command, it begins the process but later fails when it hits a superuser-only roadblock. This leaves you with an incomplete process. Now when you decide to add sudo, it attempts the same process again but finds out that someone without the right privilege has made a mess or is still messing around.
Then the solution will be to cancel out whatever the first command has started and try again.
sudo lsof -i :25672
This list out details about the port 25672
You will see the PID (process ID) e.g 1301
Then stop the process on that port with:
sudo kill <PID>
for example, sudo kill 1301
And make sure you are killing the right process if not you may get into trouble.
Now, retry the command with sudo:
sudo rabbitmq-server
ALSO,
In most cases, this error occurs because without deliberately stopping the rabbitmq-server, it always keeps running even after you restart you system.
another way to stop rabitmq server windows+R then type "services.msc" and then find for RabitMq.slelect and stop from left top corner.
Then re run your rabitmq server.
-Hi guys, I am putting up an answer that can help Googlers to run multiple rabbitmq-server on the same machine. Trying to achieve the latter, I ran into a similar error reported in the first place and solved that by defining:
export RABBITMQ_DIST_PORT=anything_other_than_25672
as stated in the documentation:
https://www.rabbitmq.com/networking.html#epmd-inet-dist-port-range
if you are using windows go to task manager and stop rabbitmq from running...
then reload the rabbitmq-server
For Linux others answered but in Windows you should press Ctrl+Alt+delete and select task management and in that end proccess that depends on erlang.
Note that it requires Administrator previlage.
Now enter this command to start rabbitmq-server:
rabbitmq-server start
Every time you restart your computer you should do these steps.For prevent do them again you should stop rabbitmq service from startup services.
went through same problem in windows, it is already running after installation as a service
so just enable the plugins from the rabbitmq commandline by entering the code as
rabbitmq-plugins enable management_plugin
than go to the localhost:15672 and good to go.
This means that your port 25672 is already in use
try: -
sudo lsof -i :25672
sudo kill <PID>
and now start your rabbitmq server using
sudo rabbitmq-server
I keep getting this error every time I try to do something with RabbitMQ:
attempted to contact: [fdbvhost#FORTE]
fdbvhost#FORTE:
* connected to epmd (port 4369) on FORTE
* epmd reports: node 'fdbvhost' not running at all
no other nodes on FORTE
* suggestion: start the node
current node details:
- node name: 'rabbitmq-cli-54#FORTE'
- home dir: C:\Users\Jesus
- cookie hash: iuRlQy0F81aBpoY9aQqAzw==
This is the output I get when I run rabbitmqctl -n fdbvhost status or /rabbitmqctl -n fdbvhost list_vhosts.
I've tried rabbitmqctl -n fdbvhost start which gives me the following output:
Error: could not recognise command
Usage:
rabbitmqctl [-n <node>] [-t <timeout>] [-q] <command> [<command options>]
...
So this doesn't start it. I cannot find anything about starting a node in the documentation. How do I actually start my node/vhost?
Try running the following command from the RabbitMQ's installation sbin directory
rabbitmq-server start -detached
This should start the broker node if it was stopped for some reason.
Check if you have RabbitMQ installed as a service in the /etc/init.d/ folder
sudo su # might be needed
cd /etc/init.d/
ls . | grep rabbit
The output should be rabbitmq-server
If that's the case, then, try restarting your service with:
sudo service rabbitmq-server restart
For mac users
To Start
brew services start rabbitmq
To Restart
brew services restart rabbitmq
To Stop
brew services stop rabbitmq
To Know the status of the server
brew services info rabbitmq

You need not necessary to contact broker if you are on the same machine.
so try this command

offline indicates that do not try to contact the broker.
I was getting the same error when trying to enable management console. To my suprise I typed http://localhost:15672/#/ in the browser and I could get to setup stuff through the management console. I had checked the availability of all the ports and everything looked good.
So I think that error is kind of misleading. Just try to go to the console in browser.

Failed to start rabbitmq-management plugin on Windows
I have installed rabbitmq on ubuntu and trying to start it using rabbitmq-server start, however, I'm getting this error:
Activating RabbitMQ plugins ...
0 plugins activated:
node with name "rabbit" already running on "mybox"
diagnostics:
- nodes and their ports on mybox: [{rabbit,38618},

- current node cookie hash: 8QRKGluOJOcZ4AAkEdFwQg==
so I try to stop it or restart it using service rabbitmq-server restart but I get the following error: Restarting rabbitmq-server: RabbitMQ is not running
The server's host name hostname -s is mybox.
How do I stop the currently running instance, or at least, how do I manage it? I have no access to it and yet I'm not able to run rabbitmq properly.
Thank you.
Rabbitmq is set to start automatically after it's installed.
I don't think it is configured run with the service command.
To see the status of rabbitmq
sudo rabbitmqctl status
To stop the rabbitmq
sudo rabbitmqctl stop
(Try the status command again to see that it's stopped).
To start it again, the recommended method is
sudo invoke-rc.d rabbitmq-server start
These all work with the vanilla ubuntu install using apt-get
Still not working?
If you've tried unsuccessfully to start or restart rabbitmq, check to see how many processes are running.
ps -ef | grep rabbit
There should be 5 processes running as the user rabbitmq.
If you have more, particularly if they're running as other users (such as root, or your own user) you should stop these processes.
The cleanest way is probably to reboot your machine.
rabbitmq-server refuses to start if the hostname -s value has changed.
The solution suggested here is only for test/development environments.
I had to delete the database to fix it locally.
i.e empty folder /var/lib/rabbitmq (ubuntu) or /usr/local/var/lib/rabbitmq/(mac)
I had similar problem but these suggestions didn't work for me(restart too). When I run rabbitmq-server command, I get a response like that:
$/ rabbitmq-server
BOOT FAILED

Error description:
{error,{cannot_log_to_file,"/var/log/rabbitmq/rabbit#haber01.log",

When I checked permissions of /var/log/rabbitmq/rabbit#haber01.log file, I saw that group has not write permisson for that file. So I gave permission to group with that command:
/var/log/rabbigmq/$ chmod g+w *
then problem has gone!
Maybe this answer help someone.
Seems like the Mnesia database was corrupted. Had to delete it to get sudo service rabbitmq-server start going again !
$ sudo rm -rf /var/lib/rabbitmq/mnesia/
Also make sure that any stray rabbit processes are killed before clearing out
$ ps auxww | grep rabbit | awk '{print $2}' | sudo xargs kill -9
And then
$ sudo service rabbitmq-server start
If you use celery, your queues could reach max size and rabbit won't start because of that. Maybe you wouldn't even able to use rabbitmqctl, so if you can afford to clean the queues, just remove
/var/lib/rabbitmq/mnesia/rabbit#<host>/queues
on unix (look for mnesia DB path on your system).
Be careful: this will remove everything you have in rabbit, so this is a last solution ever.
Have a look what is in the log of the node that you are trying to start. It will be in /var/log/rabbitmq/
It was selinux in my case, rabbit could not bind to its ports.
My brew version of rabbitmq refused to start (after working fine for years without modification by me) too.
$ cat /usr/local/etc/rabbitmq/rabbitmq-env.conf
CONFIG_FILE=/usr/local/etc/rabbitmq/rabbitmq
NODE_IP_ADDRESS=127.0.0.1
NODENAME=rabbit#localhost
RABBITMQ_LOG_BASE=/usr/local/var/log/rabbitmq
I edited out rabbit# on NODENAME and brew services restart rabbitmq started working again.
If the standard stop and start are not working, list the rabbitmq processes that are running using
ps aux | grep rabbitmq
Kill the beam.smp process using
kill -9 {process id}
and start the rabbitmq-server again.
Rabbitmq server does not start, saying it's already running:

Any takers?
The rabbitmq server was running somewhere but it just couldn't be connected to.
One of the following will mention something about rabbits:
$: ps aux | grep epmd
$: ps aux | grep erl
Kill the process with kill -9 {pid of rabbitmq process}
i was having the same problem then I realized I was not issuing the right command.
./rabbitmqctl stop
this works everytime, although it does take down erlang runtime too. also mind where your config file.
I used rabbitmqctl stop and then restarted using rabbitmq-server as root.
This issue can be caused by two issues:
Rabbit is already running on the server. If that is the case, use the answer you found of killing the currently running process (ps aux | grep rabbit | grep -v grep)
You have changed the IP address of your machine but not changed the /etc/hosts file to reflect the new IP address of the machine.
The more common of the issues is the first, but the harder to find is the second (especially if you have rabbit running on the other machine. If rabbit is installed on the other machine it will look at the old IP address and would see another machine already running rabbitmq and give you the same error. This has caused me grief in the past.
I was having this same error # Win 7, but the solutions above did not worked for me, what did solved was to remove and reinstall the service. Using a console with admin rights:
rabbitmq-service remove
rabbitmq-service install
I hope this might help someone else too
$CD RabbitMQ Server\rabbitmq_server-3.7.8\sbin
rabbitmq-service remove
rabbitmq-service install
Go : windows Services
Find : RabbitMQ and Start it
after this Enable plugin :
rabbitmq-plugins enable rabbitmq_management
In my case under Ubuntu 11.10 it helped to
#rabbitmqctl cluster MASTER SLAVE
#rabbitmqctl start_app
before I always got this error message...
Using admin console, in Win 2012R2 ver 3.5.5 rabbit, got it to work using the remove and install then rabbitmq-server restart
then ctr-c to terminate the job, then I was able to use the windows service console and start the rabbitMq service.
In my case(windows),
1. I just ran the stop service.
2. The started the service.
