Overview of this book

RabbitMQ is one of the most powerful Open Source message broker software, which is widely used in tech companies such as Mozilla, VMware, Google, AT&T, and so on. RabbitMQ gives you lots of fantastic and easy-to-manage functionalities to control and manage the messaging facility with lots of community support. As scalability is one of our major modern problems, messaging with RabbitMQ is the main part of the solution to this problem This book explains and demonstrates the RabbitMQ server in a detailed way. It provides you with lots of real-world examples and advanced solutions to tackle the scalability issues. You’ll begin your journey with the installation and configuration of the RabbitMQ server, while also being given specific details pertaining to the subject. Next, you’ll study the major problems that our server faces, including scalability and high availability, and try to get the solutions for both of these issues by using the RabbitMQ mechanisms. Following on from this, you’ll get to design and develop your own plugins using the Erlang language and RabbitMQ’s internal API. This knowledge will help you to start with the management and monitoring of the messages, tools, and applications. You’ll also gain an understanding of the security and integrity of the messaging facilities that RabbitMQ provides.

Management via a command line


The most powerful tool for managing RabbitMQ is rabbitmqctl, which is a command-line application that comes with the default RabbitMQ server installation bundle. Using the RabbitMQ control tool is really simple; you just need to run the tool with its parameters.

Cluster commands

In the following table, we present cluster commands:

Parameter

Description

join_cluster {clusternode} [--ram]

This joins the specified cluster to the main node. If a ram attribute is provided, RabbitMQ joins the cluster as a RAM node.

For example:

rabbitmqctl join_cluster newcl@local --ram

forget_cluster_node [--offline]

This removes the cluster node remotely. If an offline parameter is specified, RabbitMQ enables node removal from an offline node.

change_cluster_node_type {disc | ram}

This changes the type of cluster node to disc or RAM.

cluster_status

This displays the status of the cluster.

update_cluster_nodes {clusternode}

This updates all the clusters with...
