架构说明:

RocketMQ Dledger 集群架构

RocketMQ 4.5 以前的版本大多都是采用 Master-Slave 架构来部署，能在一定程度上保证数据的不丢失，也能保证一定的可用性。

但是那种方式的缺陷很明显，最大的问题就是当 Master Broker 挂了之后，没办法让 Slave Broker 自动切换为新的 Master Broker，需要手动更改配置将 Slave Broker 设置为 Master Broker，以及重启机器，这个非常麻烦。

在手式运维的期间，可能会导致系统的不可用。

使用 Dledger 技术要求至少由三个 Broker 组成，一个 Master 和两个 Slave，这样三个 Broker 就可以组成一个 Group ，也就是三个 Broker 可以分组来运行。一但 Master 宕机，Dledger 就可以从剩下的两个 Broker 中选举一个 Master 继续对外提供服务。

高可用

三个 NameServer 极端情况下，确保集群的可用性，任何两个 NameServer 挂掉也不会影响信息的整体使用。
在上图中每个 Master Broker 都有两个 Slave Broker，这样可以保证可用性，如在同一个 Dledger Group 中 Master Broker 宕机后，Dledger 会去行投票将剩下的节点晋升为 Master Broker。

高并发

假设某个Topic的每秒十万消息的写入， 可以增加 Master Broker 然后十万消息的写入会分别分配到不同的 Master Broker ，如有5台 Master Broker 那每个 Broker 就会承载2万的消息写入。

可伸缩

如果消息数量增大，需要存储更多的数量和最高的并发，完全可以增加 Broker ，这样可以线性扩展集群。

海量消息

数据都是分布式存储的，每个Topic的数据都会分布在不同的 Broker 中，如果需要存储更多的数据，只需要增加 Master Broker 就可以了。

安装rocketmq DLedger 高可用集群

系统环境：

centos 7.x
rocketmq 4.8.0 (至少要4.5+)
docker 18.09.9
docker-compose 1.29.2

服务器

10.200.26.26 部署组件：nameserver, ${brokerName}-n0, ${brokerName}-n1, ${brokerName}-n2,rocketmq-console
10.200.26.28 部署组件：nameserver, ${brokerName}-n0, ${brokerName}-n1, ${brokerName}-n2

最低高可用是3台（1组broker)
生产可以采用6台，分别部署2 组broker

目录（所有服务器）

mkdir -p /data/docker_app/rocketmq/data/broker-n{0..2}/store
mkdir -p /data/docker_app/rocketmq/data/broker-n{0..2}/conf
mkdir -p /data/docker_app/rocketmq/data/broker-n{0..2}/logs
