Rocketmq 安装 双master模式（推荐这种模式，性能最好）

1.修改hosts文件 vim /etc/hosts

192.168.119.138 rocketmq-nameserver1
192.168.119.138 rocketmq-master1
192.168.119.139 rocketmq-nameserver2
192.168.119.139 rocketmq-master2

然后重启网络

service network restart

2.解压rocketmq到指定的文件夹

tar -zxvf alibaba-rocketmq-3.2.6.tar.gz -C /usr/local

修改文件名为rocketmq

mv alibaba-rocketmq rocketmq

创建软连接（可有可无）

ln -s rocketmq rocketmq

3.创建存储的路径

mkdir /usr/local/rocketmq/store
mkdir /usr/local/rocketmq/store/commitlog
mkdir /usr/local/rocketmq/store/consumequeue
mkdir /usr/local/rocketmq/store/index

4.修改配置文件

vim /usr/local/rocketmq/conf/2m-noslave/broker-a.properties
vim /usr/local/rocketmq/conf/2m-noslave/broker-b.properties 

#所属集群名字 brokerClusterName=rocketmq-cluster
#broker名字，注意此处不同的配置文件填写的不一样 brokerName=broker-a或者broker-b
#0 表示 Master， >0 表示 Slave brokerId=0
#nameServer地址，分号分割 namesrvAddr=rocketmq-nameserver1:9876;rocketmq-nameserver2:9876
#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

#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

5.修改日志配置文件

mkdir -p /usr/local/rocketmq/logs
cd /usr/local/rocketmq/conf && sed -i 's#${user.home}#/usr/local/rocketmq#g' *.xml

6.修改启动脚本

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"

7.启动nameserver

cd /usr/local/rocketmq/bin
nohup sh mqnamesrv &

8.启动BrokerServer A（一台机器上启动a 另一台机器上启动b）

cd /usr/local/rocketmq/bin
nohup sh mqbroker -c /usr/local/rocketmq/conf/2m-noslave/broker-a.properties >/dev/null 2>&1 &

启动BrokerServer B

cd /usr/local/rocketmq/bin
nohup sh mqbroker -c /usr/local/rocketmq/conf/2m-noslave/broker-b.properties >/dev/null 2>&1 &

关闭：
关闭namesrv服务：sh mqshutdown namesrv
关闭broker服务 ：sh mqshutdown broker
9.在tomcat上部署rocketMq console
将rocketmq-console放在webapps文件夹下解压

unzip rocketmq-console.war -d rocketmq-console 

配置/usr/local/tomcatRocketmq/webapps/rocketmq-console/WEB-INF/classes文件下的config.properties

rocketmq.namesrv.addr=192.168.119.138:9876;192.168.119.139:9876
throwDone=true

运行tomcat即可
