Reset the RabbitMQ broker

In some cases, you just need to wipe everything off from your RabbitMQ server and start over. Despite being extremely stable, in some rare circumstances, you will need to completely reset RabbitMQ after encountering errors such as corrupt data, nodes permanently separated from the cluster, or an unmanageably large broker.

Recreate the virtual host from the command line

rabbitmqctl delete_vhost /
rabbitmqctl add_vhost /
rabbitmqctl set_permissions -p / monitoring ".*" ".*" ".*"
