第10章 Mosquitto桥接模式

10.1 桥接模式概述

10.2 桥接类型

本地桥接

远程桥接

10.3 配置本地桥接

# /etc/mosquitto/mosquitto.conf# 主监听器listener1883# 桥接连接connection bridge-to-remote address remote.broker.com:1883# 远程桥接的客户端IDremote_clientid bridge_local remote_username bridge_user remote_password bridge_pass# 要桥接的主题topic sensor/# out 1topic cmd/# in 1# 尝试重连try_privatetruestart_type automatic notificationstruecleansessionfalse

10.4 配置远程桥接

# /etc/mosquitto/mosquitto.conf# 桥接到云端connection cloud-bridge address cloud.mqtt.io:8883# TLS配置bridge_cafile /etc/mosquitto/ca.crt bridge_certfile /etc/mosquitto/bridge.crt bridge_keyfile /etc/mosquitto/bridge.key# 认证remote_username edge_bridge remote_password secure_password# 主题映射topic local/data/# out 1topic cloud/cmd/# in 1# 桥接配置try_privatetruecleansessionfalsekeepalive_interval60

10.5 桥接主题方向

主题方向示例

# out: 从本地发布到远程topic sensor/# out 1# in: 从远程订阅到本地topic cmd/# in 1# both: 双向转发topic status/# both 1

10.6 桥接连接流程

10.7 多桥接配置

# /etc/mosquitto/mosquitto.conf# 桥接1: 到数据中心connection datacenter-bridge address dc1.mqtt.io:1883 topic aggregate/# out 1remote_clientid bridge_to_dc1 remote_username bridge remote_password pass# 桥接2: 到备份中心connection backup-bridge address dc2.mqtt.io:1883 topic aggregate/# out 1remote_clientid bridge_to_dc2 remote_username bridge remote_password pass# 桥接3: 到云端connection cloud-bridge address cloud.mqtt.io:8883 bridge_cafile /etc/mosquitto/ca.crt topic sensor/# out 1topic cloud/cmdin1

多桥接架构

10.8 桥接监控

# 桥接状态mosquitto_sub-v-t"$SYS/broker/connection/#"# 桥接消息统计$SYS/broker/connection/bridge-local/state$SYS/broker/connection/bridge-local/messages/received$SYS/broker/connection/bridge-local/messages/sent

10.9 桥接应用场景

场景1: 边缘云计算

场景2: 多地域部署

# 区域Aconnection to-region-b address region-b.mqtt.io:1883 topic region-a/# both 1# 区域Bconnection to-region-a address region-a.mqtt.io:1883 topic region-b/# both 1
