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
join_cluster {clusternode} [--ram]
clusternode
Node to cluster with.
[--ram]
If provided, the node will join the cluster as a RAM node.
Instruct the node to become a member of the cluster that the specified node is in.
Before clustering, the node is reset, so be careful when using this command. For this
command to succeed the RabbitMQ application must have been stopped, e.g. with
stop_app.
Cluster nodes can be of two types: disc or RAM. Disc nodes replicate data in RAM and
on disc, 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 (with the exception of queue contents, which can reside on disc if the queue is
persistent or too big to fit in memory) and are mainly used for scalability. RAM nodes
are more performant only when managing resources (e.g. adding/removing queues,
exchanges, or bindings). A cluster must always have at least one disc node, and
usually should have more than one.
The node will be a disc node by default. If you wish to create a RAM node, provide the
--ram flag.
After executing the cluster command, whenever the RabbitMQ application is started on
the current node it will attempt to connect to the nodes that were in the cluster when
the node went down.
To leave a cluster, reset the node. You can also remove nodes remotely with the
forget_cluster_node command.
For more details see the clustering guide[2].
cluster_status
Displays all the nodes in the cluster grouped by node type, together with the
currently running nodes.
change_cluster_node_type {disc | ram}
Changes the type of the cluster node. The node must be stopped for this operation to
succeed, and when turning a node into a RAM node the node must not be the only disc
node in the cluster.
forget_cluster_node [--offline]
[--offline]
Enables node removal from an offline node. This is only useful in the situation
where all the nodes are offline and the last node to go down cannot be brought
online, thus preventing the whole cluster from starting. It should not be used in
any other circumstances since it can lead to inconsistencies.
Removes a cluster node remotely. The node that is being removed must be offline, while
the node we are removing from must be online, except when using the --offline flag.
When using the --offline flag the node you connect to will become the canonical source
for cluster metadata (e.g. which queues exist), even if it was not before. Therefore
you should use this command on the latest node to shut down if at all possible.
update_cluster_nodes {clusternode}
clusternode
The node to consult for up to date information.
Instructs an already clustered node to contact clusternode to cluster when waking up.
This is different from join_cluster since it does not join any cluster - it checks
that the node is already in a cluster with clusternode.
The need for this command is motivated by the fact that clusters can change while a
node is offline. Consider the situation in which node A and B are clustered. A goes
down, C clusters with B, and then B leaves the cluster. When A wakes up, it'll try to
contact B, but this will fail since B is not in the cluster anymore.
update_cluster_nodes -n A C will solve this situation.
sync_queue {queue}
queue
The name of the queue to synchronise.
Instructs a mirrored queue with unsynchronised slaves to synchronise itself. The queue
will block while synchronisation takes place (all publishers to and consumers from the
queue will block). The queue must be mirrored for this command to succeed.
Note that unsynchronised queues from which messages are being drained will become
synchronised eventually. This command is primarily useful for queues which are not
being drained.
cancel_sync_queue {queue}
queue
The name of the queue to cancel synchronisation for.
Instructs a synchronising mirrored queue to stop synchronising itself.
User management
Note that rabbitmqctl manages the RabbitMQ internal user database. Users from any
alternative authentication backend will not be visible to rabbitmqctl.
add_user {username} {password}
username
The name of the user to create.
password
The password the created user will use to log in to the broker.
delete_user {username}
username
The name of the user to delete.
change_password {username} {newpassword}

newpassword
The new password for the user.
clear_password {username}
username
The name of the user whose password is to be cleared.
set_user_tags {username} {tag ...}
username
The name of the user whose tags are to be set.
tag
Zero, one or more tags to set. Any existing tags will be removed.
list_users
Lists users. Each result row will contain the user name followed by a list of the tags
set for that user.
Access control
Note that rabbitmqctl manages the RabbitMQ internal user database. Permissions for users
from any alternative authorisation backend will not be visible to rabbitmqctl.
add_vhost {vhostpath}
vhostpath
The name of the virtual host entry to create.
Creates a virtual host.
delete_vhost {vhostpath}

to include in the results. The column order in the results will match the order of the
parameters. vhostinfoitem can take any value from the list that follows:
name
The name of the virtual host with non-ASCII characters escaped as in C.

Parameter Management
Certain features of RabbitMQ (such as the federation plugin) are controlled by dynamic,
cluster-wide parameters. Each parameter consists of a component name, a name and a value,
and is associated with a virtual host. The component name and name are strings, and the
value is an Erlang term. Parameters can be set, cleared and listed. In general you should
refer to the documentation for the feature in question to see how to set parameters.

Clears a parameter.
component_name
The name of the component for which the parameter is being cleared.
name
The name of the parameter being cleared.

Server Status
The server status queries interrogate the server and return a list of results with
tab-delimited columns. Some queries (list_queues, list_exchanges, list_bindings, and
list_consumers) accept an optional vhost parameter. This parameter, if present, must be
specified immediately after the query.
The list_queues, list_exchanges and list_bindings commands accept an optional virtual host
parameter for which to display results. The default value is "/".

the queue is synchronising.
If no queueinfoitems are specified then queue name and depth are displayed.
list_exchanges [-p vhostpath] [exchangeinfoitem ...]
Returns exchange details. Exchange details of the / virtual host are returned if the
"-p" flag is absent. The "-p" flag can be used to override this default.
