Application Management¶

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

hipe_compile directory

Performs HiPE-compilation and caches resulting .beam-files in the given directory.

Parent directories are created if necessary. Any existing .beam files from the directory are automatically deleted prior to compilation.

To use this precompiled files, you should set RABBITMQ_SERVER_CODE_PATH environment variable to directory specified in hipe_compile invokation.

For example, to HiPE-compile modules and store them to /tmp/rabbit-hipe/ebin directory:

rabbitmqctl hipe_compile /tmp/rabbit-hipe/ebin

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 resets the RabbitMQ node:

rabbitmqctl reset

rotate_logs

Instructs the RabbitMQ node to perform internal log rotation.

Log rotation is performed according to lager settings specified in configuration file.

Note that there is no need to call this command in case of external log rotation (e.g. from logrotate(8)), because lager detects renames and automatically reopens log files.

For example, this command starts internal log rotation process:

rabbitmqctl rotate_logs

Rotation is performed asynchronously, so there is no guarantee that it will be completed when this command returns.

shutdown

Shuts down the Erlang process on which RabbitMQ is running. The command is blocking and will return after the Erlang process exits. If RabbitMQ fails to stop, it will return a non-zero exit code.

Unlike the stop command, the shutdown command:

• does not require a pid_file to wait for the Erlang process to exit
• returns a non-zero exit code if RabbitMQ node is not running

For example, to shut down the Erlang process on which RabbitMQ is running:

rabbitmqctl shutdown

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.

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 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.

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 erlang node is not started within --timeout the command will fail. 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

Cluster Management¶

join_cluster clusternode [--ram]

clusternode

Node to cluster with.

--ram

If provided, the node will join the cluster as a RAM node.

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 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 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 more details see the Clustering guide.

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

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

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

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

rename_cluster_node oldnode1 newnode1 [oldnode2 newnode2 ...]

Supports renaming of cluster nodes in the local database.

This subcommand causes rabbitmqctl to temporarily become the node in order to make the change. The local cluster node must therefore be completely stopped; other nodes can be online or offline.

This subcommand takes an even number of arguments, in pairs representing the old and new names for nodes. You must specify the old and new names for this node and for any other nodes that are stopped and being renamed at the same time.

It is possible to stop all nodes and rename them all simultaneously (in which case old and new names for all nodes must be given to every node) or stop and rename nodes one at a time (in which case each node only needs to be told how its own name is changing).

For example, this command will rename the node “rabbit@misshelpful” to the node “rabbit@cordelia”

rabbitmqctl rename_cluster_node rabbit@misshelpful rabbit@cordelia

Note that this command only changes the local database. It may also be necessary to rename the local database directories, and to configure the new node name. For example:

1. Stop the node:
   rabbitmqctl stop rabbit@misshelpful

2. Rename the node in the local database:
   rabbitmqctl rename_cluster_node rabbit@misshelpful rabbit@cordelia

3. Rename the local database directories (note, you do not need to do this if you have set the RABBITMQ_MNESIA_DIR environment variable):

   mv \
     /var/lib/rabbitmq/mnesia/rabbit\@misshelpful \
     /var/lib/rabbitmq/mnesia/rabbit\@cordelia
   mv \
     /var/lib/rabbitmq/mnesia/rabbit\@misshelpful-rename \
     /var/lib/rabbitmq/mnesia/rabbit\@cordelia-rename
   mv \
     /var/lib/rabbitmq/mnesia/rabbit\@misshelpful-plugins-expand \
     /var/lib/rabbitmq/mnesia/rabbit\@cordelia-plugins-expand
           

4. If you have /etc/rabbitmq/rabbitmq-env.conf and configured the node name there, update this configuration.

5. Start the node when ready

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. The following command will solve this situation:

update_cluster_nodes -n A C

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 next time you ask it to. If any changes happened to the cluster after this node shut down, they will be lost.

If the last node to go down is permanently lost then you should use forget_cluster_node --offline in preference to this command, as it will ensure that mirrored queues which were mastered on the lost node get promoted.

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

rabbitmqctl force_boot

sync_queue [-p vhost] 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 [-p vhost] queue

queue

The name of the queue to cancel synchronisation for.

Instructs a synchronising mirrored queue to stop synchronising itself.

purge_queue [-p vhost] queue

queue

The name of the queue to purge.

Purges a queue (removes all messages in it).

set_cluster_name name

Sets the cluster name to name. The cluster name is announced to clients on connection, and used by the federation and shovel plugins to record where a message has been. The cluster name is by default derived from the hostname of the first node in the cluster, but can be changed.

For example, this sets the cluster name to “london”:

rabbitmqctl set_cluster_name london

User Management¶

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.

For example, this command instructs the RabbitMQ broker to create a (non-administrative) user named “tonyg” with (initial) password “changeit”:

rabbitmqctl add_user tonyg changeit

delete_user username

username

The name of the user to delete.

For example, this command instructs the RabbitMQ broker to delete the user named “tonyg”:

rabbitmqctl delete_user tonyg

change_password username newpassword

username

The name of the user whose password is to be changed.

newpassword

The new password for the user.

For example, this command instructs the RabbitMQ broker to change the password for the user named “tonyg” to “newpass”:

rabbitmqctl change_password tonyg newpass

clear_password username

username

The name of the user whose password is to be cleared.

For example, this command instructs the RabbitMQ broker to clear the password for the user named “tonyg”:

rabbitmqctl clear_password tonyg

This user now cannot log in with a password (but may be able to through e.g. SASL EXTERNAL if configured).

authenticate_user username password

username

The name of the user.

password

The password of the user.

For example, this command instructs the RabbitMQ broker to authenticate the user named “tonyg” with password “verifyit”:

rabbitmqctl authenticate_user tonyg verifyit

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.

For example, this command instructs the RabbitMQ broker to ensure the user named “tonyg” is an administrator:

rabbitmqctl set_user_tags tonyg administrator

This has no effect when the user logs in via AMQP, but can be used to permit the user to manage users, virtual hosts and permissions when the user logs in via some other means (for example with the management plugin).

This command instructs the RabbitMQ broker to remove any tags from the user named “tonyg”:

rabbitmqctl set_user_tags tonyg

list_users

Lists users. Each result row will contain the user name followed by a list of the tags set for that user.

For example, this command instructs the RabbitMQ broker to list all users:

rabbitmqctl list_users

Access Control¶

add_vhost vhost

vhost

The name of the virtual host entry to create.

Creates a virtual host.

For example, this command instructs the RabbitMQ broker to create a new virtual host called “test”:

rabbitmqctl add_vhost test

delete_vhost vhost

vhost

The name of the virtual host entry to delete.

Deletes a virtual host.

Deleting a virtual host deletes all its exchanges, queues, bindings, user permissions, parameters and policies.

For example, this command instructs the RabbitMQ broker to delete the virtual host called “test”:

rabbitmqctl delete_vhost test

list_vhosts [vhostinfoitem ...]

Lists virtual hosts.

The vhostinfoitem parameter is used to indicate which virtual host information items 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.

tracing

Whether tracing is enabled for this virtual host.

If no vhostinfoitem are specified then the vhost name is displayed.

For example, this command instructs the RabbitMQ broker to list all virtual hosts:

rabbitmqctl list_vhosts name tracing

set_permissions [-p vhost] user conf write read

vhost

The name of the virtual host to which to grant the user access, defaulting to “/”.

user

The name of the user to grant access to the specified virtual host.

write

A regular expression matching resource names for which the user is granted write permissions.

read

A regular expression matching resource names for which the user is granted read permissions.

Sets user permissions.

For example, this command instructs the RabbitMQ broker to grant the user named “tonyg” access to the virtual host called “/myvhost”, with configure permissions on all resources whose names starts with “tonyg-”, and write and read permissions on all resources:

rabbitmqctl set_permissions -p /myvhost tonyg “^tonyg-.*” “.*” “.*”

clear_permissions [-p vhost] username

vhost

The name of the virtual host to which to deny the user access, defaulting to “/”.

username

The name of the user to deny access to the specified virtual host.

For example, this command instructs the RabbitMQ broker to deny the user named “tonyg” access to the virtual host called “/myvhost”:

rabbitmqctl clear_permissions -p /myvhost tonyg

list_permissions [-p vhost]

vhost

The name of the virtual host for which to list the users that have been granted access to it, and their permissions. Defaults to “/”.

Lists permissions in a virtual host.

For example, this command instructs the RabbitMQ broker to list all the users which have been granted access to the virtual host called “/myvhost”, and the permissions they have for operations on resources in that virtual host. Note that an empty string means no permissions granted:

rabbitmqctl list_permissions -p /myvhost

list_user_permissions username

username

The name of the user for which to list the permissions.

Lists user permissions.

For example, this command instructs the RabbitMQ broker to list all the virtual hosts to which the user named “tonyg” has been granted access, and the permissions the user has for operations on resources in these virtual hosts:

rabbitmqctl list_user_permissions tonyg

set_topic_permissions [-p vhost] user exchange write read

vhost

The name of the virtual host to which to grant the user access, defaulting to “/”.

user

The name of the user the permissions apply to in the target virtual host.

exchange

The name of the topic exchange the authorisation check will be applied to.

write

A regular expression matching the routing key of the published message.

read

A regular expression matching the routing key of the consumed message.

Sets user topic permissions.

For example, this command instructs the RabbitMQ broker to let the user named “tonyg” publish and consume messages going through the “amp.topic” exchange of the “/myvhost” virtual host with a routing key starting with “tonyg-”:

rabbitmqctl set_topic_permissions -p /myvhost tonyg amq.topic “^tonyg-.*” “^tonyg-.*”

Topic permissions support variable expansion for the following variables: username, vhost, and client_id. Note that client_id is expanded only when using MQTT. The previous example could be made more generic by using “^{username}-.*”:

rabbitmqctl set_topic_permissions -p /myvhost tonyg amq.topic “^{username}-.*” “^{username}-.*”

clear_topic_permissions [-p vhost] username [exchange]

vhost

The name of the virtual host to which to clear the topic permissions, defaulting to “/”.

username

The name of the user to clear topic permissions to the specified virtual host.

exchange

The name of the topic exchange to clear topic permissions, defaulting to all the topic exchanges the given user has topic permissions for.

Clear user topic permissions.

For example, this command instructs the RabbitMQ broker to remove topic permissions for user named “tonyg” for the topic exchange “amq.topic” in the virtual host called “/myvhost”:

rabbitmqctl clear_topic_permissions -p /myvhost tonyg amq.topic

list_topic_permissions [-p vhost]

vhost

The name of the virtual host for which to list the users topic permissions. Defaults to “/”.

Lists topic permissions in a virtual host.

For example, this command instructs the RabbitMQ broker to list all the users which have been granted topic permissions in the virtual host called “/myvhost:”

rabbitmqctl list_topic_permissions -p /myvhost

list_user_topic_permissions username

username

The name of the user for which to list the topic permissions.

Lists user topic permissions.

For example, this command instructs the RabbitMQ broker to list all the virtual hosts to which the user named “tonyg” has been granted access, and the topic permissions the user has in these virtual hosts:

rabbitmqctl list_topic_user_permissions tonyg

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 term. 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"}'

clear_parameter [-p vhost] component_name key

Clears a parameter.

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 term. 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 term {"O=client,CN=guest":"/"}:

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

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

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

Policy Management¶

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, which when matches on a given resources causes the policy to apply.

apply-to

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

• queues
• 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.

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

clear_operator_policy [-p vhost] name

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

list_operator_policies [-p vhost]

Virtual Host Limits¶

set_vhost_limits [-p vhost] definition

Sets virtual host limits.

definition

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

Recognised limits are:

• max-connections
• max-queues

Use a negative value to specify "no limit".

For example, this command limits the max number of concurrent connections in vhost “qa_env” to 64:

rabbitmqctl set_vhost_limits -p qa_env '{"max-connections": 64}'

This command limits the max number of queues in vhost “qa_env” to 256:

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

This command clears the max 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}'

clear_vhost_limits [-p vhost]

Clears virtual host limits.

For example, this command clears vhost limits in vhost “qa_env”:

rabbitmqctl clear_vhost_limits -p qa_env

list_vhost_limits [-p vhost] [--global]

Displays configured virtual host limits.

--global

Show limits for all vhosts. Suppresses the -p parameter.

Server Status¶

The list_queues, list_exchanges and list_bindings commands accept an optional virtual host parameter for which to display results. The default value is “/”.

list_queues [-p vhost] [--offline | --online | --local] [queueinfoitem ...]

Returns queue details. Queue details of the “/” virtual host are returned if the -p flag is absent. The -p flag can be used to override this default.

Displayed queues can be filtered by their status or location using one of the following mutually exclusive options:

--offline

List only those durable queues that are not currently available (more specifically, their master node isn't).

--online

List queues that are currently available (their master node is).

--local

List only those queues whose master process is located on the current node.

The queueinfoitem parameter is used to indicate which queue information items to include in the results. The column order in the results will match the order of the parameters. queueinfoitem can take any value from the list that follows:

slave_pids

If the queue is mirrored, this gives the IDs of the current slaves.

synchronised_slave_pids

If the queue is mirrored, this gives the IDs of the current slaves which are synchronised with the master - i.e. those which could take over from the master without message loss.

state

The state of the queue. Normally “running”, but may be “{syncing, message_count}” if the queue is synchronising.

Queues which are located on cluster nodes that are currently down will be shown with a status of “down” (and most other queueinfoitem will be unavailable).

If no queueinfoitem are specified then queue name and depth are displayed.

For example, this command displays the depth and number of consumers for each queue of the virtual host named “/myvhost”

rabbitmqctl list_queues -p /myvhost messages consumers

list_exchanges [-p vhost] [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.

rabbitmqctl list_exchanges -p /myvhost name type

list_bindings [-p vhost] [bindinginfoitem ...]

Returns binding details. By default the bindings for the “/” virtual host are returned. The -p flag can be used to override this default.

The bindinginfoitem parameter is used to indicate which binding information items to include in the results. The column order in the results will match the order of the parameters. bindinginfoitem can take any value from the list that follows:

source_name

The name of the source of messages to which the binding is attached. With non-ASCII characters escaped as in C.

source_kind
