rabbitmqctl -qs -p <vhost-name> list_queues name > queue_names.lst

User Management

# List all users
rabbitmqctl list_users

# Create a new user
rabbitmqctl add_user "username"
rabbitmqctl set_permissions -p "custom-vhost" "username" ".*" ".*" ".*"

# Tag the user with "administrator" for full management UI and HTTP API access
rabbitmqctl set_user_tags username administrator

Recreate the virtual host

rabbitmqctl delete_vhost <my-vhost-name>
rabbltmqctl add_vhost <my-vhost-name>

Reset the RabbitMQ Node

The broker drops all virtual hosts, queues, exchanges, and non-administrative users.

rabbitmqctl stop_app
rabbitmqctl reset
rabbitmqctl start_app

Force Reset the RabbitMQ Node

如果 Cluster 損壞且無法恢復運作時，可以嘗試強制重設 Node。

rabbitmqctl stop_app
rabbitmqctl force_reset
rabbitmqctl start_app

Suspend all listeners and prevent new client connections

rabbitmqctl suspend_listeners

# suspends listeners on node rabbit@node2.cluster.rabbitmq.svc: it won't accept any new client connections
rabbitmqctl suspend_listeners -n rabbit@node2.cluster.rabbitmq.svc

# To resume all listeners on a node and make it accept new client connections again
rabbitmqctl resume_listeners
# resumes listeners on node rabbit@node2.cluster.rabbitmq.svc: it will accept new client connections again
rabbitmqctl resume_listeners -n rabbit@node2.cluster.rabbitmq.svc
rabbitmqadmin

Basic Operation

# List queus
rabbitmqadmin list queues
rabbitmqadmin -H <RabbitMQ-Server-IP> -u <username> -p <password> -V <vhost-name> list queues

# Add a queue with optional parameters
rabbitmqadmin declare queue name=<my-new-queu> durable=true auto_delete=true

rabbitmqadmin -f tsv -q list queues name > q.txt
while read -r name; do rabbitmqadmin -q delete queue name="${name}"; done < q.txt
