RocketMq集群搭建（两主两从异步刷新）

一、环境配置

-两台Centos7.6系统服务器（暂记为172.18.71.231和172.18.71.232）
-rocketmq4.7.0
-jdk1.8

二、部署步骤

1、上传rocketmq-all-4.7.0-bin-release.zip版本压缩包到两台服务器/usr/local下

2、解压缩并重命名文件夹

unzip  rocketmq-all-4.7.0-bin-release.zip

mv /usr/local/rocketmq-all-4.7.0-bin-release /usr/local/rocketmq

3、修改节点172.18.71.231的broker-a.properties主要内容为如下:若无特殊需要只修改namesrvaddr地址即可

vim /usr/local/rocketmq/conf/2m-2s-async/broker-a.properties

#所属集群名字
brokerClusterName=rocketmq-cluster
#broker名字，名字可重复,为了管理,每个master起一个名字,他的slave同他,eg:Amaster叫broker-a,他的slave也叫broker-a
brokerName=broker-a
#0 表示 Master，>0 表示 Slave
brokerId=0
#nameServer地址，分号分割
namesrvAddr=172.18.71.231:9876;172.18.71.231:9876
#在发送消息时，自动创建服务器不存在的topic，默认创建的队列数
defaultTopicQueueNums=4
#是否允许 Broker 自动创建Topic，建议线下开启，线上关闭
autoCreateTopicEnable=true
#是否允许 Broker 自动创建订阅组，建议线下开启，线上关闭
autoCreateSubscriptionGroup=true
#Broker 对外服务的监听端口,
listenPort=10911
#删除文件时间点，默认凌晨 4点
deleteWhen=04
#文件保留时间，默认 48 小时
fileReservedTime=120
#commitLog每个文件的大小默认1G
mapedFileSizeCommitLog=1073741824
#ConsumeQueue每个文件默认存30W条，根据业务情况调整
mapedFileSizeConsumeQueue=300000
#destroyMapedFileIntervalForcibly=120000
#redeleteHangedFileInterval=120000
#检测物理文件磁盘空间
diskMaxUsedSpaceRatio=88
#存储路径
storePathRootDir=/usr/local/rocketmq/store/broker-a
#commitLog 存储路径

#消息索引存储路径
storePathIndex=/usr/local/rocketmq/store/broker-a/index
#checkpoint 文件存储路径

#abort 文件存储路径
abortFile=/usr/local/rocketmq/store/abort
#限制的消息大小
maxMessageSize=65536
#flushCommitLogLeastPages=4
#flushConsumeQueueLeastPages=2
#flushCommitLogThoroughInterval=10000
#flushConsumeQueueThoroughInterval=60000
#Broker 的角色
#- ASYNC_MASTER 异步复制Master
#- SYNC_MASTER 同步双写Master
#- SLAVE
brokerRole=ASYNC_MASTER
#刷盘方式
#- ASYNC_FLUSH 异步刷盘
#- SYNC_FLUSH 同步刷盘
flushDiskType=ASYNC_FLUSH
#checkTransactionMessageEnable=false
#发消息线程池数量
#sendMessageThreadPoolNums=128
#拉消息线程池数量
#pullMessageThreadPoolNums=128

4、修改节点172.18.71.231的broker-b-s.properties主要内容为如下同样若无特殊需要只修改namesrvaddr即可

vim /usr/local/rocketmq/conf/2m-2s-async/broker-b-s.properties

#所属集群名字
brokerClusterName=rocketmq-cluster
#broker名字，名字可重复,为了管理,每个master起一个名字,他的slave同他,eg:Amaster叫broker-a,他的slave也叫broker-a
brokerName=broker-b
#0 表示 Master，>0 表示 Slave
brokerId=1
#nameServer地址，分号分割
namesrvAddr=172.18.71.231:9876;172.18.71.231:9876
#在发送消息时，自动创建服务器不存在的topic，默认创建的队列数
defaultTopicQueueNums=4
#是否允许 Broker 自动创建Topic，建议线下开启，线上关闭
autoCreateTopicEnable=true
#是否允许 Broker 自动创建订阅组，建议线下开启，线上关闭
autoCreateSubscriptionGroup=true
#Broker 对外服务的监听端口,
listenPort=10920
#删除文件时间点，默认凌晨 4点
deleteWhen=04
#文件保留时间，默认 48 小时
fileReservedTime=120
#commitLog每个文件的大小默认1G
mapedFileSizeCommitLog=1073741824
#ConsumeQueue每个文件默认存30W条，根据业务情况调整
mapedFileSizeConsumeQueue=300000
#destroyMapedFileIntervalForcibly=120000
#redeleteHangedFileInterval=120000
#检测物理文件磁盘空间
diskMaxUsedSpaceRatio=88
#存储路径
storePathRootDir=/usr/local/rocketmq/store/broker-b-s
#commitLog 存储路径
storePathCommitLog=/usr/local/rocketmq/store/broker-b-s/commitlog
#消费队列存储路径存储路径
storePathConsumeQueue=/usr/local/rocketmq/store/broker-b-s/consumequeue
#消息索引存储路径
storePathIndex=/usr/local/rocketmq/store/broker-b-s/index
#checkpoint 文件存储路径
storeCheckpoint=/usr/local/rocketmq/store/checkpoint
#abort 文件存储路径
abortFile=/usr/local/rocketmq/store/abort
#限制的消息大小
maxMessageSize=65536
#flushCommitLogLeastPages=4
#flushConsumeQueueLeastPages=2
#flushCommitLogThoroughInterval=10000
#flushConsumeQueueThoroughInterval=60000
#Broker 的角色
#- ASYNC_MASTER 异步复制Master
#- SYNC_MASTER 同步双写Master
#- SLAVE
brokerRole=SLAVE
#刷盘方式
#- ASYNC_FLUSH 异步刷盘
#- SYNC_FLUSH 同步刷盘
flushDiskType=ASYNC_FLUSH
#checkTransactionMessageEnable=false
#发消息线程池数量
#sendMessageThreadPoolNums=128
#拉消息线程池数量
#pullMessageThreadPoolNums=128

5、按照172.18.71.231的配置修改172.18.71.232的配置文件。broker-b.properties和broker-a-s.properties

6、创建相应文件夹

172.18.71.231执行

mkdir -p /usr/local/rocketmq/store/broker-a /usr/local/rocketmq/store/broker-a/nsumequeue /usr/local/rocketmq/store/broker-a/commitlog /usr/local/rocketmq/store/broker-a/index /usr/local/rocketmq/logs /usr/local/rocketmq/store/broker-b-s /usr/local/rocketmq/store/broker-b-s/nsumequeue /usr/local/rocketmq/store/broker-b-s/commitlog /usr/local/rocketmq/store/broker-b-s/index

172.18.71.232执行

mkdir -p /usr/local/rocketmq/store/broker-a-s /usr/local/rocketmq/store/broker-a-s/nsumequeue /usr/local/rocketmq/store/broker-a-s/commitlog /usr/local/rocketmq/store/broker-a-s/index /usr/local/rocketmq/logs /usr/local/rocketmq/store/broker-b /usr/local/rocketmq/store/broker-b/nsumequeue /usr/local/rocketmq/store/broker-b/commitlog /usr/local/rocketmq/store/broker-b/index

7、按照顺序启动服务

1)启动172.18.71.231的nameServer

nohup sh /usr/local/rocketmq/bin/mqnamesrv >/usr/local/rocketmq/logs/mqnamesrv.log 2>&1 &

2)启动172.18.71.232的nameServer

nohup sh /usr/local/rocketmq/bin/mqnamesrv >/usr/local/rocketmq/logs/mqnamesrv.log 2>&1 &

3)启动172.18.71.231的broker-a

nohup sh /usr/local/rocketmq/bin/mqbroker -c /usr/local/rocketmq/conf/2m-2s-async/broker-a.properties > /usr/local/rocketmq/logs/broker-a.log 2>&1 &

4)启动172.18.71.232的broker-a-s

nohup sh /usr/local/rocketmq/bin/mqbroker -c /usr/local/rocketmq/conf/2m-2s-async/broker-a-s.properties > /usr/local/rocketmq/logs/broker-a-s.log 2>&1 &

5)启动172.18.71.232的broker-b

nohup sh /usr/local/rocketmq/bin/mqbroker -c /usr/local/rocketmq/conf/2m-2s-async/broker-b.properties > /usr/local/rocketmq/logs/broker-b.log 2>&1 &

6)启动172.18.71.231的broker-b-s

nohup sh /usr/local/rocketmq/bin/mqbroker -c /usr/local/rocketmq/conf/2m-2s-async/broker-b-s.properties > /usr/local/rocketmq/logs/broker-b-s.log 2>&1 &

8、查看集群状态

sh /usr/local/rocketmq/bin/mqadmin clusterList -n 172.18.71.231:9876
