一。修改每臺主機的hosts文件 vi /.etc/hosts
120.77.61.XX nameserv1
120.76.232.XXX nameserv2
120.77.61.XX broker-a
120.76.232.XXX broker-b
120.77.61.XX broker-a-s
120.76.232.XXX broker-b-s
二。配置模板生成
mkdir ../conf/me-2m-2s-async/
sh mqbroker -m >../conf/me-2m-2s-async/broker.p
二。broker配置
拷貝生成的模板內容，打開需要修改的配置文件地址 cd /usr/local/RocketMQ-3.5.8/target/alibaba-rocketmq-broker/alibaba-rocketmq/conf/2m-2s-async
修改該文件夾下配置 vi broker-a.properties
namesrvAddr：爲hosts中配置的nameserv
brokerIP1：爲當前機器ip
brokerName：與host中配置一致
brokerId：0表示爲master，大於0表示爲slave
brokerRole:ASYNC_MASTER爲主，SLAVE爲從
namesrvAddr=nameserv1:9876;nameserv2:9876
brokerIP1=120.77.61.47
brokerName=broker-a
brokerClusterName=DefaultCluster
brokerId=0
autoCreateTopicEnable=true
autoCreateSubscriptionGroup=true
rejectTransactionMessage=false
fetchNamesrvAddrByAddressServer=false
storePathRootDir=/root/store
storePathCommitLog=/root/store/commitlog
flushIntervalCommitLog=1000
flushCommitLogTimed=false
deleteWhen=04
fileReservedTime=72
maxTransferBytesOnMessageInMemory=262144
maxTransferCountOnMessageInMemory=32
maxTransferBytesOnMessageInDisk=65536
maxTransferCountOnMessageInDisk=8
accessMessageInMemoryMaxRatio=40
messageIndexEnable=true
messageIndexSafe=false
haMasterAddress=
brokerRole=ASYNC_MASTER
flushDiskType=ASYNC_FLUSH
cleanFileForciblyEnable=true
三。複製broker-a.properties,broker-a-s.properties,broker-b.properties,broker-b-s.properties 到另外所有主機
注：爲了讓主broker crash時候能正常用，所以一臺服務器放本服務master，而從放在另一臺服務器如
120.77.61.XX 啓動 broker-a
和broker-b-s
120.76.232.XXX
啓動broker-b 和broker-a-s
四。啓動每臺機器nameserv 注：啓動順序namesrv-->broker,關閉順序相反
進入以下目錄:/usr/local/RocketMQ-3.5.8/target/alibaba-rocketmq-broker/alibaba-rocketmq/bin
啓動nameserv ：nohup sh mqnamesrv > /usr/local/RocketMQ-3.5.8/logs/namesrv.log 2>&1 &
日誌輸出以下信息表示成功：The Name Server boot success. serializeType=JSON
五。啓動每臺broker
進入 /usr/local/RocketMQ-3.5.8/target/alibaba-rocketmq-broker/alibaba-rocketmq/bin
nohup sh mqbroker -nlocalhost:9876 autoCreateTopicEnable=true -c /usr/local/RocketMQ-3.5.8/target/alibaba-rocketmq-broker/alibaba-rocketmq/conf/2m-2s-async/broker-a.properties > /usr/local/RocketMQ-3.5.8/logs/broker.log
2>&1 &
