This article mainly explains "what are the basic operations of RabbitMQ command line and control console". Interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn what are the basic operations of the RabbitMQ command line and the console.

Preface

In the previous article, we introduced the construction of RabbitMQ: the installation of RabbitMQ and the comparison of the major mainstream message middleware: this chapter mainly introduces how our previously installed console is used and how to operate through the command line.

1. Command line operations 1.1 Command operations for basic services

Rabbitmqctl stop_app: close the application

Rabbitmqctl start_app: launch the application

Rabbtmqctl status: node statu

Rabbitmqctl add_user username password: adding user

Rabbitmqctl list_users: list all users

Rabbitmqctl delete_user username: deleting a user

Rabbitmqctl clear_permissions-p vhostpath username: clear user permissions

Rabbitmqctl list_user_permissions_username: list user permissions

Rabbitmqctl change_password username newpassword: changing password

Rabbitmqctl set_permissions-p vhostpath username ". *": set user permissions

There are many more user commands involved, so I won't enumerate them here.

1.2 commands for rabbitmq specific components 1.2.1 operate on virtual hosts

Rabbitmqctl add_vhost vhostpath: creating a virtual host

Rabbitmqctl list_vhosts: list all virtual hosts

Rabbitmqctl list_permissions-p vhostpath: lists all permissions on the virtual host

Rabbitmqctl delete_vhost vhostpath: delete virtual host

1.2.2 queue operation

Rabbitmqctl list_queues: view all queue information

Rabbitmqctl-p vhostpath purge_queue bule: clears messages from the queue

1.3 Advanced Operation

Rabbitmqctl reset: remove all data, to use after rabbitmqctl stop_app

Rabbitmqctl join_clust [- ram]: cluster command

Rabbitmqctl clustr_status: view cluster status

Rabbitmqctl change_cluster_node_type disc | ram modifies the storage form of cluster nodes

Rabbitmqctl forget_cluster_node [- offline] forget node (remove node)

Rabbitmqctl rename_cluster_node oldnode1 newnode1 [oldnode2] [newnode2..] (modify node name)

two。 Introduction of the control console

Log in to the RabbitMQ web administration interface: http://localhost:15672/

The default initial user name and password is: guest

Note: the port in the administrative background of RabbitMQ is 15672 and RabbitMQ listens on port 5672 and port 5672 to connect to RabbitMQ!

2.1 introduction to the Overview (overview) interface

You can see from the figure:

The version number of RabbitMQ and Erlang installation: RabbitMQ xxx, Erlang xxx.

The upper right corner can set the page "refresh time" (5 seconds, 10 seconds, 30 seconds, do not refresh several options). Select the "virtual host" to monitor. The name of the node. Logged in user

2.1.1 Overview-> Totals

If there is any news, there will be a corresponding graphical display.

Ready: total number of messages to be consumed

Unacked: total number of messages to be answered

Total: total Ready+Unacked

The rate at which Disk read:queue reads messages from disk

The rate at which Disk write:queue writes messages from disk

Global counts

Total number of tcp connections for Connections:client

Channels: the total number of channels

Exchanges: total number of switches

Queues: total number of queu

Consumers: total number of consumers

2.1.1 Overview-> Node

Properties of Broker

Name:broker name

File descriptors and restrictions opened by File descriptors:broker.

The number and limits of network sockets managed by Socket descriptors:broker. When the restrictions are exhausted, RabbitMQ will stop accepting new network connections.

The number of processes started by Erlang processes:erlang.

Memory: the memory currently occupied by broker.

Disk space: the hard disk currently occupied by broker.

Uptime: how long the current broker is running continuously.

Info: information about the cluster.

Reset stats: restart a single node or the entire cluster.

2.1.3 Overview-> Ports and contexts

Amqp: communication port with application: 5672

Clustering: communication port with cluster: 25672

Web contexts: console port number: 15672

2.1.4 Overview-> Export definitions

The definition consists of users, virtual hosts, permissions, parameters, exchanges, queues, and bindings. They do not include the contents of the queue or the cluster name. Exclusive queues are not exported.

2.1.5 Overview-> Import definitions

The imported definition is merged with the current definition. If an error occurs during the import process, any changes made will not be rolled back.

2.2 introduction to Connections (connection) interface

Properties of the connection

Virtual host: the virtual host to which it belongs

Name: name

User name: user name used

State: current status, running: running; idle: idle

SSL/TLS: whether to connect using ssl

Protocol: protocol used

Channels: the total number of channel created

From client: packets sent per second

To client: packets received per second

Channels currently connects all created channels

2.3 introduction of Channels (channel) interface

Properties of the channel

Channel: name

Node: node name

Virtual host: the virtual host to which it belongs

User name: user name used

Mode: Channel guarantee mode. It can be one of the following, or not: C: confirm. T:transactional (transaction)

State: current status, running: running; idle: idle

Unconfirmed: the total number of messages waiting for confirm

Prefetch: the number of prefetch set

Unacker: the total number of messages waiting for ack

Rate of publish:producter pub messages

Rate of confirm:producter confirm messages

The rate at which deliver/get:consumer gets messages

Rate of ack:consumer ack messages

2.4introduction of Exchanges (switch) interface

Switch attribute

Virtual host: the virtual host to which it belongs

Name: name

Type:exchange type

Features: function. It can be one of the following, or not: d: persistence. T:Internal, the modification feature means that the exchange cannot be used by client to push messages, but only for binding between exchange and exchange, otherwise messages can be pushed or bound.

Message rate in: the rate at which messages enter

Message rate out: the rate of messages going out

Introduction to 2.5 Queues (queue) interface

Properties of the queue

Virtual host: the virtual host to which it belongs.

Name: name.

Features: function. It can be one of the following, or not: d: persistence.

State: current status, running: running; idle: idle.

Ready: the total number of messages to be consumed.

Unacked: the total number of messages to be answered.

Total: total Ready+Unacked.

Incoming: the rate at which messages enter.

Deliver/get: the rate at which messages are obtained.

Ack: the rate at which messages are answered.

2.6 introduction to the Admin (user Management) interface

Operations such as users or virtual hosts can be added in the Admin interface.
