vi /mydata/rocketmq/conf/broker.conf

所属集群名称，如果节点较多可以配置多个

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 = broker-a

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

有三个值：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

设置broker节点所在服务器的ip地址

brokerIP1 = 服务器IP

磁盘使用达到95%之后,生产者再写入消息会报错 CODE: 14 DESC: service not available now, maybe disk full

diskMaxUsedSpaceRatio=95
