RABBITMQCTL(1) RabbitMQ Service RABBITMQCTL(1)
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.
Diagnostic information is displayed if the broker was not running, could not be reached, or rejected the connection due to mismatching
Erlang cookies.
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 [pid_file]
Stops the Erlang node on which RabbitMQ is running. To restart the node follow the instructions for Running the Server in the
installation guide[1].
If a pid_file is specified, also waits for the process specified there to terminate. See the description of the wait command below for
details on this file.
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.
wait {pid_file}
Wait for the RabbitMQ application to start.
This command will wait for the RabbitMQ application to start at the node. It will wait for the pid file to be created, then for a
process with a pid specified in the pid file to start, and then for the RabbitMQ application to start in that process. It will fail if
the process terminates without starting the RabbitMQ application.
A suitable pid file is created by the rabbitmq-server script. By default this is located in the Mnesia directory. Modify the
RABBITMQ_PID_FILE environment variable to change the location.
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 appends the contents of its log files to files with names composed of the original name and the suffix, and then
resumes logging to freshly created files at the original location. I.e. effectively the current log contents are moved to the end of
the suffixed files.
When the target files do not exist they are created. When no suffix is specified, the empty log files are simply created at the
original location; no rotation takes place.
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 clustering guide[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.
cluster_status
Displays all the nodes in the cluster grouped by node type, together with the currently running nodes.

rabbitmqctl.

acknowledgements are expected from the consumer.

EXAMPLES
rabbitmqctl stop
This command instructs the RabbitMQ node to terminate.
rabbitmqctl stop_app
This command instructs the RabbitMQ node to stop the RabbitMQ application.
rabbitmqctl start_app
This command instructs the RabbitMQ node to start the RabbitMQ application.
rabbitmqctl wait /var/run/rabbitmq/pid

This command instructs the RabbitMQ node to append the contents of the log files to files with names consisting of the original logs'
names and ".1" suffix, e.g. rabbit@mymachine.log.1 and rabbit@mymachine-sasl.log.1. Finally, logging resumes to fresh files at the old
locations.
rabbitmqctl cluster rabbit@tanto hare@elena
This command instructs the RabbitMQ node to join the cluster with nodes rabbit@tanto and hare@elena. If the node is one of these then
it becomes a disk node, otherwise a ram node.
rabbitmqctl cluster_status
This command displays the nodes in the cluster.
rabbitmqctl add_user tonyg changeit

(for example with the management plugin).
