rabbitmqctl - Man Page

await_startup

Waits for the RabbitMQ application to start on the target node

For example, to wait for the RabbitMQ application to start:

rabbitmqctl await_startup

reset

Returns 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.

For example, to reset the RabbitMQ node:

rabbitmqctl reset

rotate_logs

Instructs the RabbitMQ node to perform internal log rotation.

Log rotation is performed according to the logging settings specified in the configuration file. The rotation operation is asynchronous, there is no guarantee that it will complete before this command returns.

Note that there is no need to call this command in case of external log rotation (e.g. from logrotate(8)).

For example, to initial log rotation:

rabbitmqctl rotate_logs

shutdown

Shuts down the node, both RabbitMQ and its runtime. The command is blocking and will return after the runtime process exits. If RabbitMQ fails to stop, it will return a non-zero exit code. This command infers the OS PID of the target node and therefore can only be used to shut down nodes running on the same host (or broadly speaking, in the same operating system, e.g. in the same VM or container)

Unlike the stop command, the shutdown command:

• does not require a pid_file to wait for the runtime process to exit

• returns a non-zero exit code if the RabbitMQ node is not running

For example, this will shut down a local RabbitMQ node running with the default node name:

rabbitmqctl shutdown

start_app

Starts the RabbitMQ application.

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

For example, to instruct the RabbitMQ node to start the RabbitMQ application:

rabbitmqctl start_app

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.

If a pid_file is specified, also waits for the process specified there to terminate. See the description of the wait command for details on this file.

For example, to instruct the RabbitMQ node to terminate:

rabbitmqctl stop

stop_app

Stops the RabbitMQ application, leaving the runtime (Erlang VM) running.

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

For example, to instruct the RabbitMQ node to stop the RabbitMQ application:

rabbitmqctl stop_app

wait pid_file, wait --pid pid

Waits 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 if pidfile is specified, then for a process with a pid specified in the pid file or the --pid argument, and then for the RabbitMQ application to start in that process. It will fail if the process terminates without starting the RabbitMQ application.

If the specified pidfile is not created or the erlang node is not started within --timeout the command will fail. The default timeout is 10 seconds.

A suitable pid file is created by the rabbitmq-server(8) script. By default, this is located in the Mnesia directory. Modify the RABBITMQ_PID_FILE environment variable to change the location.

For example, this command will return when the RabbitMQ node has started up:

rabbitmqctl wait /var/run/rabbitmq/pid

await_online_nodes count

Waits for count nodes to join the cluster

For example, to wait for two RabbitMQ nodes to start:

rabbitmqctl await_online_nodes 2

change_cluster_node_type type

Changes the type of the cluster node.

The type must be one of the following:

• disc

• ram

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.

For example, this command will turn a RAM node into a disc node:

rabbitmqctl change_cluster_node_type disc

cluster_status

Displays all the nodes in the cluster grouped by node type, together with the currently running nodes.

For example, this command displays the nodes in the cluster:

rabbitmqctl cluster_status

force_boot

Ensures that the node will start next time, even if it was not the last to shut down.

Normally when you shut down a RabbitMQ cluster altogether, the first node you restart should be the last one to go down, since it may have seen things happen that other nodes did not. But sometimes that's not possible: for instance, if the entire cluster loses power then all nodes may think they were not the last to shut down.

In such a case you can invoke force_boot while the node is down. This will tell the node to unconditionally start the next time you ask it. Any changes to the cluster after this node shut down will be lost.

If the last node to go down is permanently lost then you should use forget_cluster_node --offline instead of this command, as it will ensure that mirrored queues whose leader replica was on the lost node get promoted.

For example, this will force the node not to wait for other nodes the next time it is started:

rabbitmqctl force_boot

force_reset

Forcefully returns 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.

For example, to reset the RabbitMQ node:

rabbitmqctl force_reset

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 , rabbitmqctl will not attempt to connect to a node as normal; instead it will temporarily become the node in order to make the change. This is useful if the node cannot be started normally. In this case, the node 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.

For example, this command will remove the node "rabbit@stringer" from the node "hare@mcnulty":

rabbitmqctl -n hare@mcnulty forget_cluster_node rabbit@stringer

join_cluster seed-node [--ram]

seed-node

Existing cluster member (seed node) to cluster with.

--ram

If provided, the node will join the cluster as a RAM node. RAM node use is discouraged. Use only if you understand why exactly you need to use them.

Instructs 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 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 (except for queue contents, which can reside on disk 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 join_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 example, this command instructs the RabbitMQ node to join the cluster that "hare@elena" is part of, as a ram node:

rabbitmqctl join_cluster hare@elena --ram

To learn more, see the RabbitMQ Clustering guide.

sync_queue [-p vhost] queue

queue

The name of the queue to synchronise.

Instructs a mirrored queue with unsynchronised mirrors (follower replicas) to synchronise them. The queue will block while synchronisation takes place (all publishers and consumers using the queue will block or temporarily see no activity). This command can only be used with mirrored queues. To learn more, see the RabbitMQ Classic Queue Mirroring guide

Note that queues with unsynchronised replicas and active consumers will become synchronised eventually (assuming that consumers make progress). This command is primarily useful for queues that do not have active consumers.

cancel_sync_queue [-p vhost] queue

queue

The name of the queue to cancel synchronisation for.

Instructs a synchronising mirrored queue to stop synchronising itself.

Note that all user management commands rabbitmqctl only can manage users in the internal RabbitMQ database. Users from any alternative authentication backends such as LDAP cannot be inspected or managed with those commands. rabbitmqctl.

add_user username password

username

The name of the user to create.

password

For example, this command displays information about the RabbitMQ broker:

rabbitmqctl status

Certain features of RabbitMQ (such as the Federation plugin) are controlled by dynamic, cluster-wide parameters. There are 2 kinds of parameters: parameters scoped to a virtual host and global parameters. Each vhost-scoped parameter consists of a component name, a name, and a value. The component name and name are strings, and the value is a valid JSON document. A global parameter consists of a name and value. The name is a string and the value is an arbitrary Erlang data structure. 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.

Policies is a feature built on top of runtime parameters. Policies are used to control and modify the behaviour of queues and exchanges on a cluster-wide basis. Policies apply within a given vhost and consist of a name, pattern, definition, and an optional priority. Policies can be set, cleared, and listed.

clear_global_parameter name

Clears a global runtime parameter. This is similar to clear_parameter but the key-value pair isn't tied to a virtual host.

name

The name of the global runtime parameter being cleared.

For example, this command clears the global runtime parameter "mqtt_default_vhosts":

rabbitmqctl clear_global_parameter mqtt_default_vhosts

clear_parameter [-p vhost] component_name key

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.

For example, this command clears the parameter "node01" for the "federation-upstream" component in the default virtual host:

rabbitmqctl clear_parameter federation-upstream node01

list_global_parameters

Lists all global runtime parameters. This is similar to list_parameters but the global runtime parameters are not tied to any virtual host.

For example, this command lists all global parameters:

rabbitmqctl list_global_parameters

list_parameters [-p vhost]

Lists all parameters for a virtual host.

For example, this command lists all parameters in the default virtual host:

rabbitmqctl list_parameters

set_global_parameter name value

Sets a global runtime parameter. This is similar to set_parameter but the key-value pair isn't tied to a virtual host.

name

The name of the global runtime parameter being set.

value

The value for the global runtime parameter, as a JSON document. In most shells you are very likely to need to quote this.

For example, this command sets the global runtime parameter "mqtt_default_vhosts" to the JSON document {"O=client,CN=guest":"/"}:

rabbitmqctl set_global_parameter mqtt_default_vhosts '{"O=client,CN=guest":"/"}'

set_parameter [-p vhost] component_name name value

Sets a parameter.

component_name

The name of the component for which the parameter is being set.

name

The name of the parameter being set.

value

The value for the parameter, as a JSON document. In most shells you are very likely to need to quote this.

For example, this command sets the parameter "node01" for the "federation-upstream" component in the default virtual host to the following JSON "guest":

rabbitmqctl set_parameter federation-upstream node01 '{"uri":"amqp://user:password@server/%2F","ack-mode":"on-publish"}'

list_policies [-p vhost]

Lists all policies for a virtual host.

For example, this command lists all policies in the default virtual host:

rabbitmqctl list_policies

set_operator_policy [-p vhost] [--priority priority] [--apply-to apply-to] name pattern definition

Sets an operator policy that overrides a subset of arguments in user policies. Arguments are identical to those of set_policy.

Supported arguments are:

• expires

• message-ttl

• max-length

• max-length-bytes

set_policy [-p vhost] [--priority priority] [--apply-to apply-to] name pattern definition

Sets a policy.

name

The name of the policy.

pattern

The regular expression allows the policy to apply if it matches a resource name.

definition

The definition of the policy, as a JSON document. In most shells you are very likely to need to quote this.

priority

The priority of the policy as an integer. Higher numbers indicate greater precedence. The default is 0.

apply-to

Which types of objects this policy should apply to. Possible values are:

• queues (all queue types, including streams)

• classic_queues (classic queues only)

• quorum_queues (quorum queues only)

• streams (streams only)

• exchanges

• all

The default is all.

For example, this command sets the policy "federate-me" in the default virtual host so that built-in exchanges are federated:

rabbitmqctl set_policy federate-me ^amq. '{"federation-upstream-set":"all"}'

clear_policy [-p vhost] name

Clears a policy.

name

The name of the policy being cleared.

For example, this command clears the "federate-me" policy in the default virtual host:

clear_operator_policy [-p vhost] name

Clears an operator policy. Arguments are identical to those of clear_policy.

list_operator_policies [-p vhost]

Lists operator policy overrides for a virtual host. Arguments are identical to those of list_policies.

Note that rabbitmqctl manages the RabbitMQ internal user database. Permissions for users from any alternative authorisation backend will not be visible to rabbitmqctl.

This command limits the maximum number of queues in vhost "qa_env" to 256:

rabbitmqctl set_vhost_limits -p qa_env '{"max-queues": 256}'

This command clears the maximum number of connections limit in vhost "qa_env":

rabbitmqctl set_vhost_limits -p qa_env '{"max-connections": -1}'

This command disables client connections in vhost "qa_env":

rabbitmqctl set_vhost_limits -p qa_env '{"max-connections": 0}'
