创建broker服务器配置文件broker.conf

本次我们搭建三台broker服务器，分别在宿主机卷映射目录下创建我们的配置文件

1. /home/docker/rocketmq/conf/broker1/broker.conf
2. /home/docker/rocketmq/conf/broker2/broker.conf
3. /home/docker/rocketmq/conf/broker3/broker.conf

（1）创建配置文件目录，以broker1为例：

命令：mkdir -p /home/docker/rocketmq/conf/broker1

2）使用vi编辑器创建broker配置文件broker.conf，只需更改服务器名称即可

brokerClusterName = DefaultCluster
#broker名称
brokerName = rocketmq-broker-1
brokerId = 0
deleteWhen = 04
fileReservedTime = 48
brokerRole = ASYNC_MASTER
flushDiskType = ASYNC_FLUSH

启动集群并验证

命令：docker-compose -p rocketmq up -d 

 验证集群
