NAME

rabbitmqctl - command line tool for managing a RabbitMQ broker

SYNOPSIS

rabbitmqctl [-n node] [-q] {command} [command options...]

DESCRIPTION

RabbitMQ is an implementation of AMQP, the emerging standard for high performance enterprise messaging. The RabbitMQ server is a robust and scalable implementation of an AMQP broker.

rabbitmqctl is a command line tool for managing a RabbitMQ broker. It performs all actions by connecting to one of the broker's nodes.

OPTIONS

[-n node]

Default node is "rabbit@server", where server is the local host. On a host named "server.example.com", the node name of the RabbitMQ Erlang node will usually be rabbit@server (unless RABBITMQ_NODENAME has been set to some non-default value at broker startup time). The output of hostname -s is usually the correct suffix to use after the "@" sign. See rabbitmq-server(1) for details of configuring the RabbitMQ broker.

[-q]

Quiet output mode is selected with the "-q" flag. Informational messages are suppressed when quiet mode is in effect.

COMMANDS

Application and Cluster Management

stop

Stops the Erlang node on which RabbitMQ is running. To restart the node follow the instructions for Running the Server in the m[blue]installation guidem[][1].

stop_app

Stops the RabbitMQ application, leaving the Erlang node running.
This command is typically run prior to performing other management actions that require the RabbitMQ application to be stopped, e.g. reset.

start_app

Starts the RabbitMQ application.
This command is typically run after performing other management actions that required the RabbitMQ application to be stopped, e.g. reset.

status

Displays various information about the RabbitMQ broker, such as whether the RabbitMQ application on the current node, its version number, what nodes are part of the broker, which of these are running.

reset

Return a RabbitMQ node to its virgin state.
Removes the node from any cluster it belongs to, removes all data from the management database, such as configured users and vhosts, and deletes all persistent messages.
For reset and force_reset to succeed the RabbitMQ application must have been stopped, e.g. with stop_app.

force_reset

Forcefully return a RabbitMQ node to its virgin state.
The force_reset command differs from reset in that it resets the node unconditionally, regardless of the current management database state and cluster configuration. It should only be used as a last resort if the database or cluster configuration has been corrupted.
For reset and force_reset to succeed the RabbitMQ application must have been stopped, e.g. with stop_app.

rotate_logs {suffix}

Instruct the RabbitMQ node to rotate the log files.
The RabbitMQ broker will attempt to append the current contents of the log file to the file with name composed of the original name and the suffix. It will create a new file if such a file does not already exist. When no suffix is specified, the empty log file is simply created at the original location; no rotation takes place.
When an error occurs while appending the contents of the old log file, the operation behaves in the same way as if no suffix was specified.
This command might be helpful when you are e.g. writing your own logrotate script and you do not want to restart the RabbitMQ node.

Cluster management

cluster {clusternode ...}


clusternode
Subset of the nodes of the cluster to which this node should be connected.

Instruct the node to become member of a cluster with the specified nodes. To cluster with currently offline nodes, use force_cluster.

Cluster nodes can be of two types: disk or ram. Disk nodes replicate data in ram and on disk, thus providing redundancy in the event of node failure and recovery from global events such as power failure across all nodes. Ram nodes replicate data in ram only and are mainly used for scalability. A cluster must always have at least one disk node.

If the current node is to become a disk node it needs to appear in the cluster node list. Otherwise it becomes a ram node. If the node list is empty or only contains the current node then the node becomes a standalone, i.e. non-clustered, (disk) node.

After executing the cluster command, whenever the RabbitMQ application is started on the current node it will attempt to connect to the specified nodes, thus becoming an active node in the cluster comprising those nodes (and possibly others).

The list of nodes does not have to contain all the cluster's nodes; a subset is sufficient. Also, clustering generally succeeds as long as at least one of the specified nodes is active. Hence adjustments to the list are only necessary if the cluster configuration is to be altered radically.

For this command to succeed the RabbitMQ application must have been stopped, e.g. with stop_app. Furthermore, turning a standalone node into a clustered node requires the node be reset first, in order to avoid accidental destruction of data with the cluster command.

For more details see the m[blue]clustering guidem[][2].

force_cluster {clusternode ...}


clusternode
Subset of the nodes of the cluster to which this node should be connected.

Instruct the node to become member of a cluster with the specified nodes. This will succeed even if the specified nodes are offline. For a more detailed description, see cluster.

Note that this variant of the cluster command just ignores the current status of the specified nodes. Clustering may still fail for a variety of other reasons.

connectionpid
Id of the Erlang process associated with the connection to close.

If no channelinfoitems are specified then pid, user, transactional, consumer_count, and messages_unacknowledged are assumed.

list_consumers

List consumers, i.e. subscriptions to a queue's message stream. Each line printed shows, separated by tab characters, the name of the queue subscribed to, the id of the channel process via which the subscription was created and is managed, the consumer tag which uniquely identifies the subscription within a channel, and a boolean indicating whether acknowledgements are expected for messages delivered to this consumer.
The output format for "list_consumers" is a list of rows containing, in order, the queue name, channel process id, consumer tag, and a boolean indicating whether acknowledgements are expected from the consumer.

EXAMPLES
