部署架构
概述
RabbitMQ 的部署架构直接影响系统的可用性、性能和可维护性。本文档介绍 RabbitMQ 在生产环境中的部署架构最佳实践，帮助您构建稳定可靠的消息系统。
部署架构类型
1. 单节点部署
适用于开发、测试环境，不建议用于生产环境。
┌─────────────────────────────────────┐
│ 单节点架构 │
├─────────────────────────────────────┤
│ │
│ ┌─────────────────────────┐ │
│ │ RabbitMQ Server │ │

│ │ ┌─────┐ ┌─────┐ ┌────┐│ │
│ │ │Queue│ │Queue│ │ ...││ │
│ │ └─────┘ └─────┘ └────┘│ │
│ └─────────────────────────┘ │
│ │
│ 优点：部署简单，资源消耗低 │
│ 缺点：单点故障，无法扩展 │
│ │
└─────────────────────────────────────┘2. 普通集群部署
多节点共享元数据，消息仍存储在单个节点。
┌─────────────────────────────────────────────────────────────┐

│ └──────┬──────┘ └──────┬──────┘ └──────┬──────┘ │
│ │ │ │ │
│ └────────────────┴────────────────┘ │
│ 元数据同步 │
│ │
│ 优点：负载均衡，元数据共享 │
│ 缺点：消息不复制，节点故障消息丢失 │
│ │
└─────────────────────────────────────────────────────────────┘3. 镜像队列集群
消息在多个节点间复制，提供高可用性。

│ └──────────消息同步复制──────────┘ │
│ │
│ 优点：高可用，自动故障转移 │
│ 缺点：同步复制影响性能，资源消耗大 │
│ │
└─────────────────────────────────────────────────────────────┘4. 仲裁队列集群
RabbitMQ 3.8+ 推荐的高可用方案，使用 Raft 协议。
