RocketMq集群搭建
地址下载https://www.apache.org/dyn/closer.cgi?path=rocketmq/4.2.0/rocketmq-all-4.2.0-bin-release.zip
今天使用两台虚拟机搭建rocketmq集群，IP地址为192.168.21.128和192.168.21.129，
遇到一个坑耗费了比较长的时间，防火墙的问题
关闭防火墙systemctl stop firewalld
1.配置环境变量 vim / etc / profile
export ROCKETMQ_HOME = / root / svr / rocketmq
export PATH = $ PATH :: $ ROCKETMQ_HOME / bin
使配置生效源/ etc / profile
2.配置宿主，给域名服务器使用
vim / etc / hosts
192.168.214.128 rocketmq1
192.168.124.129 rocketmq2
3.配置集群参数
vim /root/svr/rocketmq/conf/2m-nosalve/broker-a.propertiesbrokerClusterName = TL-rocketmq群集
#brokerName不能相同
brokerName =经纪人一个
＃0表示Master，> 0表示Slave
brokerId = 0
＃此处使用步骤2配置额主机
namesrvAddr = rocketmq1：9876; rocketmq2：9876
defaultTopicQueueNums = 4
autoCreateTopicEnable =真
autoCreateSubscriptionGroup =真
的listenPort = 10911
deleteWhen = 04
fileReservedTime = 120
mapedFileSizeCommitLog = 1073741824
mapedFileSizeConsumeQueue = 300000
destroyMapedFileIntervalForcibly = 120000
redeleteHangedFileInterval = 120000
diskMaxUsedSpaceRatio = 88
storePathRootDir = /根/ SVR / rocketmq /数据/存储
storePathCommitLog = /根/ SVR / rocketmq /数据/存储/ commitlog
maxMessageSize = 65536
flushCommitLogLeastPages = 4
flushConsumeQueueLeastPages = 2
flushCommitLogThoroughInterval = 10000
flushConsumeQueueThoroughInterval = 60000
checkTransactionMessageEnable = FALSE
sendMessageThreadPoolNums = 128
pullMessageThreadPoolNums = 128
＃角色SYNC_MASTER / ASYNC_MASTER / SALVE
brokerRole = SYNC_MASTER
flushDiskType = ASYNC_FLUSH
4.创建存储日志文件
mkdir / root / svr / rocketmq / data（也要创建store文件夹）
mkdir / root / svr / rocketmq / data / store / commitlog
mkdir / root / svr / rocketmq / data / store / consumequeue
mkdir / root / svr / rocketmq / data / store / index
5.修改日志配置文件
| mkdir -p / root / svr / rocketmq / logs cd / root / svr / rocketmq / conf && sed -i的＃$ {user.home}＃/ root / svr / rocketmq #g' * .XML |
注意的logback。*。xml的配置文件中$ {}的user.home需要替换自己指定的目录
6.修改runbroker.sh，runserver.sh堆内存参数
7.启动服务
sh mqnamesrv＆
sh mqbroker -c /root/svr/rocketmq/conf/2m-nosalve/broker-a.properties&
8.查看集群状态
sh mqadmin clusterlist -n 192.168.214.128:9876
如果只显示当前机器的集群信息，请关闭防火墙
9.测试集群
export NAMESRV_ADDR = rocketmq1:9876
测试发送端
> sh bin / tools.sh org.apache.rocketmq.example.quickstart.Producer
测试消费端
> sh bin / tools.sh org.apache.rocketmq.example.quickstart.Consumer
10.服务停止
在cd / root / svr / rocketmq / bin目录下执行命令或者jps查看进程号kill -9 pid
| sh mqshutdown broker sh mqshutdown namesrv |
