RocketMQ-初体验RocketMQ(03)_RocketMQ多机集群部署

---

完成了单节点的RocketMQ的安装 RocketMQ-初体验RocketMQ(02)_单节点RocketMQ的安装 ，我们来搞个2个节点的集群来玩下

---

环境准备

CentOS7

192.168.18.130 、192.168.18.131

---

Q: 生产环境，假设你有2台主机，应该如何部署RocketMQ集群更HA一些？

A：

你有 A、B两台主机，

A主机 部署 ： broker-a 主节点 和 broker-b 从节点
B主机 部署： broker-b 主节点 和 borker-a 从节点

两台主机互为主备，HA更可靠一些，即使有一台主机，假设B主机 宕机了。 我们的A主机上 仍然还有是 broker-a 主节点 和 broker-b 从节点， 这个时候只是 broker-b 只能提供消费消息的能力了，不能写入了。 还是要比 整个 broker-b cluster 因为主机B的宕机而全部不能提供服务了好。

---

参考配置

在RocketMQ 安装目录 conf目录下，官方提供了一些参考配置

可以集合自己的场景，到对应的目录下看下官方推荐的配置。

---

集群搭建

130 ： brokera-m brokera-s
131: brokerb-m brokerb-s

broker集群在同一台主机上互为主备 。

每台机器上启动一个namesrv。 两个 broker节点，互为主备，构成一个broker集群。

130主机

broker 配置文件

cp 两个文件出来

broker-m.conf master节点的配置文件
broker-s.conf slave节点的配置文件

broker-m.conf

主要注意的地方

• brokerName 主从节点 保持一致
• brokerId 0 表示主节点，从节点 1,2,3…依次类推
• namesrvAddr 配置所有 namesrv的地址，多个地址 使用 ; 分开
• brokerRole 这个要注意 主节点 SYNC_MASTER 或者 ASYNC_MASTER 从节点 SLAVE
• listenPort 确定端口不要重复占用，否则启动失败

启动namesrv

nohup sh bin/mqnamesrv -n 192.168.18.130:9876& 最好通过-n指定主IP，否则的话有可能在多网卡 或者docker环境下 启动失败

[root@artisan rocketmq-all-4.3.2-bin-release]# pwd
/usr/local/rocketmq/rocketmq-all-4.3.2-bin-release

可能是mqadmin没能正确的连接进去！网络抖动，这个跟底层netty的连接有关. 多重试几次，一般都没问题。

测试消费者

[root@artisan rocketmq-all-4.3.2-bin-release]# sh bin/tools.sh  org.apache.rocketmq.example.quickstart.Consumer

运行结果 截个图

是不是希望有个页面可以管理和查看集群信息呢？ RocketMQ 提供了 RocketMQ Console ,下篇博文我们来看下如何通过拉取源码来搭建一套本地的RocketMQ Console吧

双机互为主备的配置

刚刚搭建的 是 左边的 ，生产环境更建议使用右侧的部署方式

配置的话 ，仅需要调整 broker-s.conf 中的 brokerName即可

131:
broker-s.conf

130 ：

broker-s :

启动后，打开RocketMQConsole 看下，符合部署。
