1. Introduction to RabbitMQ

• What is RabbitMQ?
  • Definition and purpose
  • Use cases
• How RabbitMQ works
  • Message broker concept
  • Key components: Producers, Consumers, Queues
• RabbitMQ Features
  • Reliability, scalability, flexibility, etc.

2. Installing RabbitMQ

• Prerequisites
  • Erlang installation
• Installation on various platforms
  • Windows
  • macOS
  • Linux (Debian/Ubuntu, CentOS)
• Starting RabbitMQ
  • Starting/stopping the RabbitMQ service
    • systemctl status rabbitmq-server
    • systemctl start rabbitmq-server
    • systemctl stop rabbitmq-server
• Web Management Plugin
  • Enabling and accessing the RabbitMQ Management Console
• Configuration rabbitmq & Nginx reverse proxy

3. RabbitMQ Basics

• Core Concepts
  • Producers, Consumers, Exchanges, and Queues
  • Bindings and Routing Keys
• Hello World Example
  • Setting up a simple producer and consumer
• Understanding AMQP Protocol
  • Overview of the Advanced Message Queuing Protocol

4. Exchanges and Routing

• Types of Exchanges
  • Direct Exchange
  • Fanout Exchange
  • Topic Exchange
  • Headers Exchange
• Use Cases for Each Type
• Configuring Routing Keys
  • Matching producers and consumers

5. Queues in Depth

• Queue Types
  • Durable, Exclusive, and Auto-Delete Queues
• Priority Queues
• Dead Letter Queues (DLQs)
• Message TTL (Time to Live)
• Acknowledgements and Durability
  • Persistent messages

6. Advanced Features

• Message Acknowledgements
  • Auto vs manual acknowledgment
• Prefetch Count
  • Optimizing consumer performance
• RabbitMQ Clustering
  • High availability and scalability
• Shovel and Federation Plugins

• SSL/TLS Setup
  • Secure connections

8. Monitoring and Management

• Management UI
  • Inspecting exchanges, queues, and connections
• Command-Line Tools
  • RabbitMQctl and RabbitMQ-diagnostics
• Monitoring Metrics
  • Message rates, queue depth, etc.

9. Integrating RabbitMQ with Applications

• Supported Languages
  • Java (using Spring Boot), Python, Node.js, etc.
• Libraries and Frameworks
  • Overview of RabbitMQ client libraries
• Examples
  • Setting up RabbitMQ with Python using pika
