[rabbitmq] Delete all the queues from RabbitMQ?

I installed rabbitmqadmin and was able to list all the exchanges and queues. How can I use rabbitmqadmin or rabbitmqctl to delete all the queues.

This question is related to rabbitmq rabbitmqctl

The answer is


Here is a way to do it with PowerShell. the URL may need to be updated

$cred = Get-Credential
 iwr -ContentType 'application/json' -Method Get -Credential $cred   'http://localhost:15672/api/queues' | % { 
    ConvertFrom-Json  $_.Content } | % { $_ } | ? { $_.messages -gt 0} | % {
    iwr  -method DELETE -Credential $cred  -uri  $("http://localhost:15672/api/queues/{0}/{1}" -f  [System.Web.HttpUtility]::UrlEncode($_.vhost),  $_.name)
 }

In Rabbit version 3.7.10 you can run below command with root permission:

rabbitmqctl list_queues | awk '{ print $1 }' | xargs -L1 rabbitmqctl delete_queue

You need not reset rabbitmq server to delete non-durable queues. Simply stop the server and start again and it will remove all the non-durable queues available.


I tried the above pieces of code but I did not do any streaming.

sudo rabbitmqctl list_queues | awk '{print $1}' > queues.txt; for line in $(cat queues.txt); do sudo rabbitmqctl delete_queue "$line"; done.

I generate a file that contains all the queue names and loops through it line by line to the delete them. For the loops, while read ... did not do it for me. It was always stopping at the first queue name.


With rabbitmqadmin you can remove them with this one-liner:

rabbitmqadmin -f tsv -q list queues name | while read queue; do rabbitmqadmin -q delete queue name=${queue}; done

Removing all queues using rabbitmqctl one liner

rabbitmqctl list_queues | awk '{ print $1 }' | sed 's/Listing//' | xargs -L1 rabbitmqctl purge_queue

I made a deleteRabbitMqQs.sh, which accepts arguments to search the list of queues for, selecting only ones matching the pattern you want. If you offer no arguments, it will delete them all! It shows you the list of queues its about to delete, letting you quit before doing anything destructive.

for word in "$@"
do
        args=true
        newQueues=$(rabbitmqctl list_queues name | grep "$word")
        queues="$queues
$newQueues"
done
if [ $# -eq 0 ]; then
        queues=$(rabbitmqctl list_queues name | grep -v "\.\.\.")
fi

queues=$(echo "$queues" | sed '/^[[:space:]]*$/d')

if [ "x$queues" == "x" ]; then
        echo "No queues to delete, giving up."
        exit 0
fi

read -p "Deleting the following queues:
${queues}
[CTRL+C quit | ENTER proceed]
"

while read -r line; do
        rabbitmqadmin delete queue name="$line"
done <<< "$queues"

If you want different matching against the arguments you pass in, you can alter the grep in line four. When deleting all queues, it won't delete ones with three consecutive spaces in them, because I figured that eventuality would be rarer than people who have rabbitmqctl printing its output out in different languages.

Enjoy!


If you're trying to delete queues because they're unused and you don't want to reset, one option is to set the queue TTL very low via a policy, wait for the queues to be auto-deleted once the TTL is passed and then remove the policy (https://www.rabbitmq.com/ttl.html).

rabbitmqctl.bat set_policy delq ".*" '{"expires": 1}' --apply-to queues

To remove the policy

rabbitmqctl clear_policy delq

Note that this only works for unused queues

For whose have a problem with installing rabbitmqadmin, You should firstly install python.

UNIX-like operating system users need to copy rabbitmqadmin to a directory in PATH, e.g. /usr/local/bin.

Windows users will need to ensure Python is on their PATH, and invoke rabbitmqadmin as python.exe rabbitmqadmin.

Then

  1. Browse to http://{hostname}:15672/cli/rabbitmqadmin to download.
  2. Go to the containing folder then run cmd with administrator privilege

To list Queues python rabbitmqadmin list queues.

To delete Queue python rabbitmqadmin delete queue name=Name_of_queue

To Delete all Queues

1- Declare Policy

python rabbitmqadmin declare policy name='expire_all_policies' pattern=.* definition={\"expires\":1} apply-to=queues

2- Remove the policy

python rabbitmqadmin  delete policy name='expire_all_policies'

Try this:

 rabbitmqadmin list queues name | awk '{print $2}' | xargs -I qn rabbitmqadmin delete queue name=qn

There's a way to remove all queues and exchanges without scripts and full reset. You can just delete and re-create a virtual host from admin interface. This will work even for vhost /.

The only thing you'll need to restore is permissions for the newly created vhost.


rabbitmqadmin list queues|awk 'NR>3{print $4}'|head -n-1|xargs -I qname rabbitmqadmin delete queue name=qname

In case you only want to purge the queues which are not empty (a lot faster):

rabbitmqctl list_queues | awk '$2!=0 { print $1 }' | sed 's/Listing//' | xargs -L1 rabbitmqctl purge_queue

For me, it takes 2-3 seconds to purge a queue (both empty and non-empty ones), so iterating through 50 queues is such a pain while I just need to purge 10 of them (40/50 are empty).


Actually super easy with management plugin and policies:

  • Goto Management Console (localhost:15672)

  • Goto Admin tab

  • Goto Policies tab(on the right side)

  • Add Policy

  • Fill Fields

    • Virtual Host: Select
    • Name: Expire All Policies(Delete Later)
    • Pattern: .*
    • Apply to: Queues
    • Definition: expires with value 1 (change type from String to Number)
  • Save

  • Checkout Queues tab again

  • All Queues must be deleted

  • And don't forget to remove policy!!!!!!.


Okay, important qualifier for this answer: The question does ask to use either rabbitmqctl OR rabbitmqadmin to solve this, my answer needed to use both. Also, note that this was tested on MacOS 10.12.6 and the versions of the rabbitmqctl and rabbitmqadmin that are installed when installing rabbitmq with Homebrew and which is identified with brew list --versions as rabbitmq 3.7.0

rabbitmqctl list_queues -p <VIRTUAL_HOSTNAME> name | sed 1,2d | xargs -I qname rabbitmqadmin --vhost <VIRTUAL_HOSTNAME> delete queue name=qname


To list queues,

./rabbitmqadmin -f tsv -q list queues

To delete a queue,

./rabbitmqadmin delete queue name=name_of_queue

Another option is to delete the vhost associated with the queues. This will delete everything associated with the vhost, so be warned, but it is easy and fast.


NOTE: the RabbitMQ team monitors the rabbitmq-users mailing list and only sometimes answers questions on StackOverflow.


This commands deletes all your queues

python rabbitmqadmin.py \
  -H YOURHOST -u guest -p guest -f bash list queues | \
xargs -n1 | \
xargs -I{} \
  python rabbitmqadmin.py -H YOURHOST -u guest -p guest delete queue name={}

This script is super simple because it uses -f bash, which outputs the queues as a list.

Then we use xargs -n1 to split that up into multiple variables

Then we use xargs -I{} that will run the command following, and replace {} in the command.


I tried rabbitmqctl and reset commands but they are very slow.

This is the fastest way I found (replace your username and password):

#!/bin/bash

# Stop on error
set -eo pipefail

USER='guest'
PASSWORD='guest'

curl -sSL -u $USER:$PASSWORD http://localhost:15672/api/queues/%2f/ | jq '.[].name' | sed 's/"//g' | xargs -L 1 -I@ curl -XDELETE -sSL -u $USER:$PASSWORD http://localhost:15672/api/queues/%2f/@
# To also delete exchanges uncomment next line
# curl -sSL -u $USER:$PASSWORD http://localhost:15672/api/exchanges/%2f/ | jq '.[].name' | sed 's/"//g' | xargs -L 1 -I@ curl -XDELETE -sSL -u $USER:$PASSWORD http://localhost:15672/api/exchanges/%2f/@

Note: This only works with the default vhost /


If you don't have rabbitmqadmin installed, try to purge queues with rabbitmqctl:

rabbitmqctl list_queues | awk '{ print $1 }' | xargs -L1 rabbitmqctl purge_queue


You can use rabbitmqctl eval as below:

rabbitmqctl eval 'IfUnused = false, IfEmpty = true, MatchRegex = 
<<"^prefix-">>, [rabbit_amqqueue:delete(Q, IfUnused, IfEmpty) || Q <- 
rabbit_amqqueue:list(), re:run(element(4, element(2, Q)), MatchRegex) 
=/= nomatch ].' 

The above will delete all empty queues in all vhosts that have a name beginning with "prefix-". You can edit the variables IfUnused, IfEmpty, and MatchRegex as per your requirement.


Here is a faster version (using parallel install sudo apt-get install parallel) expanding on the excellent answer by @admenva

parallel -j 50 rabbitmqadmin -H YOUR_HOST_OR_LOCALHOST -q delete queue name={} ::: $(rabbitmqadmin -H YOUR_HOST_OR_LOCALHOST -f tsv -q list queues name)
