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

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

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。
测试发送和消费消息

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。
