RocketMQ-4.7.0初始化安装

将多块硬盘合并

注：操作系统使用Centos7.6版本

#yum install lvm2 -y && yum -y install parted

初始化并挂载硬件

#!/bin/bash #要将所有的盘符都写上 for n in b c ;do  parted /dev/vd${n} mklabel gpt parted /dev/vd${n} mkpart vdb ext4 0 100%   << EOF I EOF parted  /dev/vd${n} toggle 1 lvm    done #要将所有的硬盘标识都写上 disk="/dev/vdb1 /dev/vdc1"  pvcreate -f $disk    vgcreate vg $disk pesize=$(vgdisplay  vg |awk '/Total/{print $NF}') #2表示只有两块硬盘写，如果有多块硬盘，需要按实际的写 lvcreate -i 2 -I 512 -l $pesize -n data vg mkfs.xfs -f /dev/vg/data mkdir -p /data/ echo '/dev/vg/data /data xfs defaults,noatime 0 0' >> /etc/fstab mount -a

系统优化参数

#/bin/bash cat >>/etc/security/limits.conf<<EOF baseuser soft nofile 655360 baseuser hard nofile 655360 EOF cat >>/etc/sysctl.conf<<EOF vm.overcommit_memory=1 vm.drop_caches=1 vm.zone_reclaim_mode=0 vm.max_map_count=655360 vm.dirty_background_ratio=25 vm.dirty_ratio=50 vm.dirty_writeback_centisecs=360000 vm.page-cluster=3 vm.swappiness=1 EOF sysctl -p /etc/sysctl.conf

创建rocketmq数据

rocketmq数据目录存放：/data/rocketmq-a

#mkdir /data/rocketmq-a && mkdir /data/logs-a &&chown -R deploy. /data/  && ll /data

解压安装包

默认将4.7的安装下载到服务器上

$unzip rocketmq-all-4.7.0-bin-release.zip -d /workspace/ && mv /workspace/rocketmq-all-4.7.0-bin-release /workspace/rocketmq-a

修改log存放路径

rocketmq日志目录存放：/data/logs-a

$cd /workspace/rocketmq-a/conf $sed -i 's#\${user.home}/logs#/data/logs-a#g' logback_broker.xml  $sed -i 's#\${user.home}/logs#/data/logs-a#g' logback_tools.xml

修改jvm参数

$cd /workspace/rocketmq-a/ $vim bin/runbroker.sh

调整启动参数

JAVA_OPT="${JAVA_OPT} -server -Xms10g -Xmx10g -Xmn4g"

更改主节点配置文件

$vim 2m-2s-async/broker-a.properties

#请修改 brokerClusterName=ClusterA brokerName=broker-a brokerId=0 listenPort=10911 #请修改 namesrvAddr=x.x.x.x:9876;x.x.x.x::9876 defaultTopicQueueNums=4 autoCreateTopicEnable=false autoCreateSubscriptionGroup=false deleteWhen=04 fileReservedTime=48 mapedFileSizeCommitLog=1073741824 mapedFileSizeConsumeQueue=50000000 destroyMapedFileIntervalForcibly=120000 redeleteHangedFileInterval=120000 diskMaxUsedSpaceRatio=88 #存储路径 storePathRootDir=/data/rocketmq-a/store #commitLog存储路径 storePathCommitLog=/data/rocketmq-a/store/commitlog #消费队列存储路径 storePathConsumeQueue=/data/rocketmq-a/store/consumequeue # 消息索引存储路径 storePathIndex=/data/rocketmq-a/store/index # checkpoint 文件存储路径 storeCheckpoint=/data/rocketmq-a/store/checkpoint #abort 文件存储路径 abortFile=/data/rocketmq-a/store/abort maxMessageSize=65536 flushCommitLogLeastPages=4 flushConsumeQueueLeastPages=2 flushCommitLogThoroughInterval=10000 flushConsumeQueueThoroughInterval=60000 brokerRole=ASYNC_MASTER flushDiskType=ASYNC_FLUSH checkTransactionMessageEnable=false maxTransferCountOnMessageInMemory=1000 transientStorePoolEnable=true warmMapedFileEnable=false pullMessageThreadPoolNums=128 slaveReadEnable=true transferMsgByHeap=true waitTimeMillsInSendQueue=1000

从节点配置

$vim 2m-2s-async/broker-a-s.properties

#请修改 brokerClusterName=ClusterA brokerName=broker-a brokerId=1 listenPort=10915 #请修改 namesrvAddr=x.x.x.x:9876;x.x.x.x:9876 defaultTopicQueueNums=4 autoCreateTopicEnable=false autoCreateSubscriptionGroup=false deleteWhen=04 fileReservedTime=120 mapedFileSizeCommitLog=1073741824 mapedFileSizeConsumeQueue=50000000 destroyMapedFileIntervalForcibly=120000 redeleteHangedFileInterval=120000 diskMaxUsedSpaceRatio=88 #存储路径 storePathRootDir=/data/rocketmq-slavea/store #commitLog存储路径 storePathCommitLog=/data/rocketmq-slavea/store/commitlog #消费队列存储路径 storePathConsumeQueue=/data/rocketmq-slavea/store/consumequeue # 消息索引存储路径 storePathIndex=/data/rocketmq-slavea/store/index # checkpoint 文件存储路径 storeCheckpoint=/data/rocketmq-slavea/store/checkpoint #abort 文件存储路径 abortFile=/data/rocketmq-slavea/store/abort maxMessageSize=65536 flushCommitLogLeastPages=4 flushConsumeQueueLeastPages=2 flushCommitLogThoroughInterval=10000 flushConsumeQueueThoroughInterval=60000 brokerRole=SLAVE flushDiskType=ASYNC_FLUSH checkTransactionMessageEnable=false maxTransferCountOnMessageInMemory=1000 transientStorePoolEnable=true warmMapedFileEnable=false pullMessageThreadPoolNums=128 slaveReadEnable=true transferMsgByHeap=true

启动broker节点

$cd /workspace/rocketmq-a/ $nohup binmq/broker -c /workspace/rocketmq-a/conf/2m-2s-async/broker-a.properties &
