事先说明
1.安装RocketMQ需要Java环境的支持
2.两主两从为了演示效果,就使用两台虚拟机
3.两条虚拟机的端口分别是
A:192.168.118.3
B:192.168.118.4
4.A机器是(A主)同时也是(B从),B机器是(B主)同时也是(A从)
1.下载安装包
1.官网下载
https://www.apache.org/dyn/closer.cgi?path=rocketmq/4.3.2/rocketmq-all-4.3.2-bin-release.zip
2.自己去找,看看版本合不合适
https://mirrors.tuna.tsinghua.edu.cn/apache/rocketmq/
2.上传和解压
创建存放压缩包的文件夹,上传压缩包到改文件夹下
cd /usr/local/
mkdir mytool
cd mytool
解压
#解压 unzip rocketmq-all-4.3.2-bin-release.zip #删除文件夹 rm -rf rocketmq-all-4.3.2-bin-release.zip #重命名 mv rocketmq-all-4.3.2-bin-release rocketmq4.3.2
3.创建持久化存储目录
按照命令执行就好了
mkdir store cd store/ mkdir commitlog mkdir consumequeue mkdir index mkdir ../store-s cd ../store-s mkdir commitlog mkdir consumequeue mkdir index
4.修改JVM参数
RocketMQ默认的JVM参数运行内存大,根据自身机器配置而言,多半是启动不成功的,所以要修改一下
找到bin目录下的这两个文件
runserver.sh文件修改,将第一行注释更改为
#JAVA_OPT="${JAVA_OPT} -server -Xms4g -Xmx4g -Xmn2g -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m" JAVA_OPT="${JAVA_OPT} -server -Xms256m -Xmx256m -Xmn512m -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m"
runbroker.sh文件修改,将第一行注释更改为
#JAVA_OPT="${JAVA_OPT} -server -Xms8g -Xmx8g -Xmn4g" JAVA_OPT="${JAVA_OPT} -server -Xms256m -Xmx256m -Xmn128m"
-------------------------------------------------------------上面的操作两条机器都要做相同的操作------------------------------------------------------------------------------
所有要修改的文件都在一个目录下,一台机器只用改两个
A改-a和-b-s,B改-b和-a-s
/usr/local/mytool/rocketmq4.3.2/conf/2m-2s-async
5.A机器配置文件修改
broker-a.properties
#所属集群名称，如果多个master，那么每个master配置的名称应该一致，要不然识别不了 brokerClusterName=rocketmq-cluster #broker名称 brokerName=broker-a #0 表示master，>0 表示slave brokerId=0 #nameServer地址，分号隔开 namesrvAddr=192.168.118.3:9876;192.168.118.4:9876 #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，建议线下开始，线上关闭 autoCreateSubscriptionGroup=true #broker对外服务的监听端口， #同一台机器部署多个broker，端口号要不同，且端口号之间要相距大些 listenPort=10911 #删除文件的时间节点，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，默认大小1g mapedFileSizeCommitLog=1073741824 #consumeQueue每个文件默认存30w条，根据自身业务进行调整 mapedFileSizeConsumeQueue=300000 destroyMapedFileInterval=120000 redeleteHangedFileInterval=120000 #检查物理文件磁盘空间 diskMaxUsedSpaceRatio=88 #store存储路径，master与slave目录要不同 storePathRootDir=/usr/local/mytool/rocketmq4.3.2/store storePathCommitLog=/usr/local/mytool/rocketmq4.3.2/store/commitlog #限制的消息大小 maxMessageSize=65536 flushCommitLogLeastPages=4 flushConsumeQueueLeastPages=2 flushCommitLogThoroughInterval=10000 flushConsumeQueueThoroughInterval=60000 checkTransactionMessageEnable=false #发消息线程池数 sendMessageThreadPoolNums=128 #拉去消息线程池数 pullMessageThreadPoolNums=128 #broker角色： #ASYSC_MASTER 异步复制master #SYSC_MASTER 同步复制master #SLAVE 从 brokerRole=SYSC_MASTER #刷盘方式 #ASYNC_FLUSH 异步刷盘 #SYNC_FLUSH 同步刷盘 flushDiskType=ASYNC_FLUSH
broker-b-s.properties
brokerClusterName=rocketmq-cluster brokerName=broker-b #0 -> master ,>0 -> slave brokerId=1 namesrvAddr=192.168.118.3:9876;192.168.118.4:9876 defaultTopicQueueNums=4 autoCreateTopicEnable=true autoCreateSubscriptionGroup=true listenPort=10950 deleteWhen=04 fileReservedTime=120 mapedFileSizeCommitLog=1073741824 mapedFileSizeConsumeQueue=300000 destroyMapedFileInterval=120000 redeleteHangedFileInterval=120000 diskMaxUsedSpaceRatio=88 storePathRootDir=/usr/local/mytool/rocketmq4.3.2/store-s storePathCommitLog=/usr/local/mytool/rocketmq4.3.2/store-s/commitlog maxMessageSize=65536 flushCommitLogLeastPages=4 flushConsumeQueueLeastPages=2 flushCommitLogThoroughInterval=10000 flushConsumeQueueThoroughInterval=60000 checkTransactionMessageEnable=false sendMessageThreadPoolNums=128 pullMessageThreadPoolNums=128 brokerRole=SLAVE flushDiskType=ASYNC_FLUSH
A机器的broker-a-s.properties和broker-b.properties其余两个文件不用管
6.B机器配置文件修改
broker-b.properties
brokerClusterName=rocketmq-cluster brokerName=broker-b brokerId=0 namesrvAddr=192.168.118.3:9876;192.168.118.4:9876 defaultTopicQueueNums=4 autoCreateTopicEnable=true autoCreateSubscriptionGroup=true listenPort=10911 deleteWhen=04 fileReservedTime=120 mapedFileSizeCommitLog=1073741824 mapedFileSizeConsumeQueue=300000 destroyMapedFileInterval=120000 redeleteHangedFileInterval=120000 diskMaxUsedSpaceRatio=88 storePathRootDir=/usr/local/mytool/rocketmq4.3.2/store storePathCommitLog=/usr/local/mytool/rocketmq4.3.2/store/commitlog maxMessageSize=65536 flushCommitLogLeastPages=4 flushConsumeQueueLeastPages=2 flushCommitLogThoroughInterval=10000 flushConsumeQueueThoroughInterval=60000 checkTransactionMessageEnable=false sendMessageThreadPoolNums=128 pullMessageThreadPoolNums=128 brokerRole=SYSC_MASTER flushDiskType=ASYNC_FLUSH
broker-a-s.properties
brokerClusterName=rocketmq-cluster brokerName=broker-a brokerId=1 namesrvAddr=192.168.118.3:9876;192.168.118.4:9876 defaultTopicQueueNums=4 autoCreateTopicEnable=true autoCreateSubscriptionGroup=true listenPort=10950 deleteWhen=04 fileReservedTime=120 mapedFileSizeCommitLog=1073741824 mapedFileSizeConsumeQueue=300000 destroyMapedFileInterval=120000 redeleteHangedFileInterval=120000 diskMaxUsedSpaceRatio=88 storePathRootDir=/usr/local/mytool/rocketmq4.3.2/store-s storePathCommitLog=/usr/local/mytool/rocketmq4.3.2/store-s/commitlog maxMessageSize=65536 flushCommitLogLeastPages=4 flushConsumeQueueLeastPages=2 flushCommitLogThoroughInterval=10000 flushConsumeQueueThoroughInterval=60000 checkTransactionMessageEnable=false sendMessageThreadPoolNums=128 pullMessageThreadPoolNums=128 brokerRole=SLAVE flushDiskType=ASYNC_FLUSH
7.开始启动
1.先分别启动两台机器的NameServer
切换到bin目录下
cd /usr/local/mytool/rocketmq4.3.2/bin #启动nameser nohup sh mqnamesrv &
2.按照顺序启动borker
#A机器 nohup sh mqbroker -c /usr/local/mytool/rocketmq4.3.2/conf/2m-2s-async/broker-a.properties & #B机器 nohup sh mqbroker -c /usr/local/mytool/rocketmq4.3.2/conf/2m-2s-async/broker-b.properties & #A机器 nohup sh mqbroker -c /usr/local/mytool/rocketmq4.3.2/conf/2m-2s-async/broker-b-s.properties & #B机器 nohup sh mqbroker -c /usr/local/mytool/rocketmq4.3.2/conf/2m-2s-async/broker-a-s.properties &
3.常用命令
1.查看nameServer进程
ps -ef | grep mqnamesrv
正常启动情况
2.查看broker进程
ps -ef | grep mqbroker
正常启动情况
也可以用jps命令进行查看
打开RocketMQ的控制台进行查看,如下图就代表已经配置完成
8.控制台配置
1.控制台工程下载地址
https://github.com/apache/rocketmq-externals
2.将下载到本机后的工程解压
进入下面的目录
rocketmq-externals ocketmq-consolesrcmain esources
修改application.properties配置文件
也可以修改他的端口号,默认就是8080
windows中打开命令提示符,切换到此目录下
执行打包命令
mvn clean package -Dmaven.test.skip=true
之后会生成上图编译之后的target目录
将rocketmq-console-ng-1.0.1.jar上传到任意一个有java环境的虚拟机上
在虚拟机此jar的目录中执行
java -jar rocketmq-console-ng-1.0.1.jar
用浏览器访问此虚拟机的ip加上端口进行访问
所有虚拟机的防火墙都是关闭的,否在无法进行请求和通讯
