rockemq linux-集群搭建

一。修改每台主机的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

拷贝生成的模板内容，打开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

修改该文件夹下配置 vi broker-a.properties

namesrvAddr：为hosts中配置的nameserv

brokerIP1：为当前机器ip

brokerName：与host中配置一致

brokerId：0表示为master，大于0表示为slave

brokerRole:ASYNC_MASTER为主，SLAVE为从

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。复制broker-a.properties,broker-a-s.properties,broker-b.properties,broker-b-s.properties 到另外所有主机

注：为了让主broker crash时候能正常用，所以一台服务器放本服务master，而从放在另一台服务器如

120.77.61.XX 启动 broker-a 和broker-b-s

120.76.232.XXX 启动broker-b 和broker-a-s

四。启动每台机器nameserv注：启动顺序namesrv-->broker,关闭顺序相反

进入以下目录:/usr/local/RocketMQ-3.5.8/target/alibaba-rocketmq-broker/alibaba-rocketmq/bin

    启动nameserv ：nohup sh mqnamesrv > /usr/local/RocketMQ-3.5.8/logs/namesrv.log 2>&1 &

日志输出以下信息表示成功：The Name Server boot success. serializeType=JSON

五。启动每台broker

进入 /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 &
