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
[root@artisan rocketmq-all-4.3.2-bin-release]# pwd /usr/local/rocketmq/rocketmq-all-4.3.2-bin-release [root@artisan rocketmq-all-4.3.2-bin-release]# nohup sh bin/mqnamesrv -n 192.168.18.130:9876& [1] 9236 [root@artisan rocketmq-all-4.3.2-bin-release]# nohup: ignoring input and appending output to ‘nohup.out’ tail -f nohup.out 日志如下： Java HotSpot(TM) 64-Bit Server VM warning: Using the DefNew young collector with the CMS collector is deprecated and will likely be removed in a future release Java HotSpot(TM) 64-Bit Server VM warning: UseCMSCompactAtFullCollection is deprecated and will likely be removed in a future 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。

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。
