安装步骤：【两台机器同样操作 以201为例】
步骤一：解压安装文件alibaba-rocketmq-3.2.6.tar.gz
[root@201 rocketmq]# tar -zxvf alibaba-rocketmq-3.2.6.tar.gz -C /usr/local [root@201 rocketmq]# mv alibaba-rocketmq rocketmq
步骤二：修改配置
配置一：创建存储路径 用于存储队列 索引 提交日志等信息
[root@201 rocketmq]# mkdir -p /usr/local/rocketmq/store [root@201 rocketmq]# mkdir -p /usr/local/rocketmq/store/commitlog [root@201 rocketmq]# mkdir -p /usr/local/rocketmq/store/consumequeue [root@201 rocketmq]# mkdir -p /usr/local/rocketmq/store/index
配置二：Hosts添加信息
192.168.1.201 rocketmq-nameserver1 192.168.1.202 rocketmq-nameserver2 192.168.1.203 rocketmq-nameserver3 192.168.1.204 rocketmq-nameserver4 192.168.1.201 rocketmq-master1 192.168.1.202 rocketmq-master2 192.168.1.203 rocketmq-slave1 192.168.1.204 rocketmq-slave2
重启网卡：service network restart
相互ping一下，在201机器上ping 192.168.1.202 ping rocketmq-nameserver2 ping rocketmq-master2 。 202 203 204机器上也一样。
配置三：RocketMQ配置文件：
同步双写，配置目录：2m-2s-async
异步刷盘，配置目录：2m-2s-sync
#201 vim /usr/local/rocketmq/conf/2m-2s-sync/broker-a.properties #202 vim /usr/local/rocketmq/conf/2m-2s-sync/broker-b.properties #203 vim /usr/local/rocketmq/conf/2m-2s-sync/broker-a-s.properties #204 vim /usr/local/rocketmq/conf/2m-2s-sync/broker-b-s.properties
#所属集群名字 brokerClusterName=rocketmq-cluster #broker名字 broker-a.properties填broker-a broker-b.properties填broker-b brokerName=broker-a #0 表示 Master，>0 表示 Slave brokerId=0 #nameServer地址，分号分割 namesrvAddr=rocketmq-nameserver1:9876 rocketmq-nameserver2:9876 rocketmq-nameserver3:9876 rocketmq-nameserver4:9876 #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 #commitLog 存储路径 storePathCommitLog=/usr/local/rocketmq/store/commitlog #消费队列存储路径存储路径 storePathConsumeQueue=/usr/local/rocketmq/store/consumequeue #消息索引存储路径 storePathIndex=/usr/local/rocketmq/store/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=SYNC_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
注意：
brokerName:
201 broker-a
202 broker-b
203 broker-a-s
204 broker-b-s
brokerId
201 202 是master 配置brokerId=0
203 204 是slave 配置brokerId=1
brokerRole
201 202是master 配置 brokerRole=SYNC_MASTER
203 204是slave配置 brokerRole=SLAVE
配置四：修改日志配置文件
[root@201 conf]# mkdir -p /usr/local/rocketmq/logs [root@201 conf]# cd /usr/local/rocketmq/conf && sed -i 's#${user.home}#/usr/local/rocketmq#g' *.xml
配置五：修改启动脚本参数 Xms和Xmx至少是1G 否则启动不起来 Xmn一般是前者的一半
vim /usr/local/rocketmq/bin/runbroker.sh JAVA_OPT="${JAVA_OPT} -server -Xms1g -Xmx1g -Xmn512m -XX:PermSize=128m -XX:MaxPermSize=320m" vim /usr/local/rocketmq/bin/runserver.sh JAVA_OPT="${JAVA_OPT} -server -Xms1g -Xmx1g -Xmn512m -XX:PermSize=128m -XX:MaxPermSize=320m"
步骤三：启动：先启动两台机器的NameServer，再启动两台机器的Borker，关机的时候顺序相反，先关闭两台机器的Broker，再关闭两台机器的Nameserver。在启动 BrokerServer 之前先关闭防火墙.
