[rabbitmq-discuss] listing bindings for a queue

Thu Sep 23 09:41:35 BST 2010

A quick and dirty solution could be to modify the rabbitmqctl script and add there whatever the root /root/.erlang.cookie is

You could edit or create a new version of that script modifying the exec part:

exec erl \
    -pa "${RABBITMQ_HOME}/ebin" \
    -noinput \
    -hidden \
    ${RABBITMQ_CTL_ERL_ARGS} \
    -sname rabbitmqctl$$ \
    -s rabbit_control \
    -nodename $RABBITMQ_NODENAME \
    -setcookie COOKIEVALUE
    -extra "$@"

I've added this line there: -setcookie COOKIEVALUE

Another way to do that is to modify your local .erlang.cookie to be the same as the root one.

Regards,

Alvaro

When the workflow is changed, the affected nodes are restarted and they reconnect to AMQP (rabbitmq) and declare their input queue and its bindings. In order to ensure that no unwanted (stale) subscriptions are still active I need to call "queue.unbind" on them. So far so good. BUT in order to do that I need to be able to list active bindings for a given queue. I wasn't able to find such method wether in the amqp spec nor in any of the API's. What am I missing? I can see this information by calling
