本节内容延续前期博客内容，使用docker-compose一键式搭建docker环境下的RocketMQ集群及其管理工具，实现rocketmq在docker环境容器外部访问。特别说明，内网版的RocketMQ集群只能实现docker环境内部访问，并不适用于测试使用，本节内容通过搭建外网版的RocketMQ集群，实现docker容器中和宿主机都可以使用的消息中间键集群。

创建docker-compose的rocketmq.yml启动脚本

PS: 特别说明，这里区别于内网版，为了避免broker之间外网访问端口冲突，内网的端口broker2使用20911，broker3使用30911

创建broker服务器配置文件broker.conf

①创建映射目录

mkdir -p /usr/local/bin/atp/rocketmq/conf/broker1

mkdir -p /usr/local/bin/atp/rocketmq/conf/broker2

mkdir -p /usr/local/bin/atp/rocketmq/conf/broker3

②使用vi编辑器创建broker配置文件broker.conf,完成配置文件的映射

broker1服务器配置

#broker1服务器配置

brokerClusterName = DefaultCluster

#broker名称，master和slave使用相同的名称，表明他们的主从关系
brokerName = rocketmq-broker-1

#0表示master，大于0表示不同的slave
brokerId = 0

#表示几点做消息删除动作，默认是凌晨4点
deleteWhen = 04

#在磁盘上保留消息的时长，单位是小时
fileReservedTime = 48

#sync_master，async_master，slave；同步和异步表示master和slave之间同步数据的机制
brokerRole = ASYNC_MASTER

#刷盘策略，取值为：async_flush，sync_flush表示同步刷盘和异步刷盘；sync_flush消息写入磁盘后才返回成功状态，async_flush不需要；
flushDiskType = ASYNC_FLUSH

#broker外网访问的ip地址
brokerIP1 = 192.168.56.10

#broker服务端口
listenPort = 10911

broker2服务器配置

#broker2服务器配置

brokerClusterName = DefaultCluster

#broker名称，master和slave使用相同的名称，表明他们的主从关系
brokerName = rocketmq-broker-2

#0表示master，大于0表示不同的slave
brokerId = 0

#表示几点做消息删除动作，默认是凌晨4点
deleteWhen = 04

#在磁盘上保留消息的时长，单位是小时
fileReservedTime = 48

#sync_master，async_master，slave；同步和异步表示master和slave之间同步数据的机制
brokerRole = ASYNC_MASTER

#刷盘策略，取值为：async_flush，sync_flush表示同步刷盘和异步刷盘；sync_flush消息写入磁盘后才返回成功状态，async_flush不需要；
flushDiskType = ASYNC_FLUSH

#broker外网访问的ip地址
brokerIP1 = 192.168.56.10

#broker服务端口
listenPort = 20911

broker3服务器配置

#broker2服务器配置

brokerClusterName = DefaultCluster

#broker名称，master和slave使用相同的名称，表明他们的主从关系
brokerName = rocketmq-broker-3

#0表示master，大于0表示不同的slave
brokerId = 0

#表示几点做消息删除动作，默认是凌晨4点
deleteWhen = 04

#在磁盘上保留消息的时长，单位是小时
fileReservedTime = 48

#sync_master，async_master，slave；同步和异步表示master和slave之间同步数据的机制
brokerRole = ASYNC_MASTER

#刷盘策略，取值为：async_flush，sync_flush表示同步刷盘和异步刷盘；sync_flush消息写入磁盘后才返回成功状态，async_flush不需要；
flushDiskType = ASYNC_FLUSH

#broker外网访问的ip地址
brokerIP1 = 192.168.56.10

#broker服务端口
listenPort = 30911

PS: 其它配置同上，注意修改broker的名称和端口号，brokerIP1为宿主机的IP

使用docker-compose启动RocketMQ集群

命令：

docker-compose -f rocketmq.yml -p rocketmq up -d

访问RocketMQ控制台，验证集群安装状态
