==========================================================================================

一、RocketMQ简介

==========================================================================================

RocketMQ是一款分布式、队列模型的消息中间件，具有以下特点：

1、支持严格的消息顺序；

2、支持Topic与Queue两种模式；

3、亿级消息堆积能力；

4、比较友好的分布式特性；

5、同时支持Push与Pull方式消费消息；

 

==========================================================================================

二、服务器分布

==========================================================================================

1、相关说明

IP地址

主机名

机型

角色

架构模式

10.217.121.123

rocketmq-master1

128G内存

nameserver、brokerserver

Master1（双Master模式）

10.217.122.31

rocketmq-master2

128G内存

nameserver、brokerserver

Master2（双Master模式）

 

2、hosts信息添加

# vim /etc/hosts

10.217.121.123  mqnameserver1

10.217.122.31    mqnameserver2

10.217.121.123  rocketmq-master1

10.217.122.31    rocketmq-master2

 

3、系统环境

CentOS 6.3

 

4、总体架构

 

==========================================================================================

三、RocketMQ安装与配置

==========================================================================================

1、JDK安装

# tar xvzf jdk-7u65-linux-x64.gz -C /usr/local

# rm -f jdk-7u65-linux-x64.gz

# cd /usr/local && ln -s jdk1.7.0_65 jdk

# cd /usr/local/bin && ln -s /usr/local/jdk/bin/java

 

2、RocketMQ安装

# tar xvzf alibaba-rocketmq-3.1.7.tar.gz -C /usr/local

# mv alibaba-rocketmq alibaba-rocketmq-3.1.7

# ln -s alibaba-rocketmq-3.1.7 rocketmq

# rm alibaba-rocketmq-3.1.7.tar.gz

# ll /usr/local

 

3、环境变量设置

# vim /etc/profile

export PATH=$PATH:/usr/local/bin

 

export JAVA_HOME=/usr/local/jdk

export CLASSPATH=.:$JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

export PATH=$PATH:$JAVA_HOME/bin

 

export ROCKETMQ_HOME=/usr/local/rocketmq

export PATH=$PATH::$ROCKETMQ_HOME/bin

 

# source /etc/profile

# cd /usr/local/rocketmq/bin && sh os.sh

 

4、主机名设置

(1)、Master1服务器

# vim /etc/hosts

10.217.121.123  mqnameserver1

10.217.122.31    mqnameserver2

10.217.121.123  rocketmq-master1

10.217.122.31    rocketmq-master2

 

# sed -i  '/HOSTNAME/d' /etc/sysconfig/network

# echo 'HOSTNAME=rocketmq-master1'  >> /etc/sysconfig/network

# hostname rocketmq-master1

 

(2)、Master2服务器

# vim /etc/hosts

10.217.121.123  mqnameserver1

10.217.122.31    mqnameserver2

10.217.121.123  rocketmq-master1

10.217.122.31    rocketmq-master2

 

# sed -i  '/HOSTNAME/d' /etc/sysconfig/network

# echo 'HOSTNAME=rocketmq-master2'  >> /etc/sysconfig/network

# hostname rocketmq-master2

 

5、RocketMQ配置

(1)、Master1服务器

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

brokerClusterName=AdpMqCluster

brokerName=broker-a

brokerId=0

namesrvAddr=mqnameserver1:9876;mqnameserver2:9876

defaultTopicQueueNums=4

autoCreateTopicEnable=true

autoCreateSubscriptionGroup=true

listenPort=10911

deleteWhen=04

fileReservedTime=120

mapedFileSizeCommitLog=1073741824

mapedFileSizeConsumeQueue=50000000

destroyMapedFileIntervalForcibly=120000

redeleteHangedFileInterval=120000

diskMaxUsedSpaceRatio=88

 

storePathRootDir=/data/rocketmq/store

storePathCommitLog=/data/rocketmq/store/commitlog

 

maxMessageSize=65536

 

flushCommitLogLeastPages=4

flushConsumeQueueLeastPages=2

flushCommitLogThoroughInterval=10000

flushConsumeQueueThoroughInterval=60000

 

brokerRole=ASYNC_MASTER

flushDiskType=ASYNC_FLUSH

 

checkTransactionMessageEnable=false

 

sendMessageThreadPoolNums=128

pullMessageThreadPoolNums=128

 

(2)、Master2服务器

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

brokerClusterName=AdpMqCluster

brokerName=broker-b

brokerId=1

namesrvAddr=mqnameserver1:9876;mqnameserver2:9876

defaultTopicQueueNums=4

autoCreateTopicEnable=true

autoCreateSubscriptionGroup=true

listenPort=10911

deleteWhen=04

fileReservedTime=120

mapedFileSizeCommitLog=1073741824

mapedFileSizeConsumeQueue=50000000

destroyMapedFileIntervalForcibly=120000

redeleteHangedFileInterval=120000

diskMaxUsedSpaceRatio=88

 

storePathRootDir=/data/rocketmq/store

storePathCommitLog=/data/rocketmq/store/commitlog

 

maxMessageSize=65536

 

flushCommitLogLeastPages=4

flushConsumeQueueLeastPages=2

flushCommitLogThoroughInterval=10000

flushConsumeQueueThoroughInterval=60000

 

brokerRole=ASYNC_MASTER

flushDiskType=ASYNC_FLUSH

 

checkTransactionMessageEnable=false

 

sendMessageThreadPoolNums=128

pullMessageThreadPoolNums=128

 

(3)、runbroker.sh参数调整

runbroker.sh需要根据内存大小进行适当地调整

JAVA_OPT_1="-server-Xms80g -Xmx80g -Xmn20g -XX:PermSize=1g -XX:MaxPermSize=1g"

 

6、服务启动

# mkdir -p /data/rocketmq/store/commitlog  /data/logs

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

 

(1)、启动NameServer【master1、master2】

# cd /usr/local/rocketmq/bin

# nohup sh mqnamesrv &

# nohup sh mqnamesrv >/var/log/ns.log &# nohup sh mqbroker -c ../conf/2m-noslave/broker-a.properties > /var/log/mq.log 2>&1 &

 

(2)、启动BrokerServer A【master1】

# cd /usr/local/rocketmq/bin

# nohup sh mqbroker -c ../conf/2m-noslave/broker-a.properties  >/dev/null 2>&1 &

 

(3)、启动BrokerServer B【master2】

# cd /usr/local/rocketmq/bin

# nohup sh mqbroker -c ../conf/2m-noslave/broker-b.properties  >/dev/null 2>&1 &

 

# netstat -ntlp

 

# jps

 

==========================================================================================

四、RocketMQ服务健康监控

==========================================================================================

1、依赖组件安装

# yum -y install nmap

 

2、nameserver监控

# vim /data/scripts/check_nameserver_health.sh

#!/bin/sh

TMP_SRV_PROT=`echo ${SRV_PROT} | tr '[A-Z]' '[a-z]'`

  

if [[ "${TMP_SRV_PROT}" == "tcp" ]]; then

       PROT_OPT="S"

elif [[ "${TMP_SRV_PROT}" == "udp" ]]; then

       PROT_OPT="U"

else

       echo "未知的协议类型！" && exit1

fi

  

## 最多扫描3次，成功一次即可，以避免网络抖动而导致误判

for ((i=0; i<3; i++)); do

       RETVAL=`/usr/bin/nmap -n -s${PROT_OPT} -p ${SRV_PORT} ${ETH1_ADDR} | grep open`

       [[ -n "${RETVAL}" ]] && SCAN_FLAG=1;break || sleep 10

done

  

if [[ ${SCAN_FLAG} -ne 1 ]]; then

       [[ -n `ps aux | grep java | grep namesrv` ]] && kill -9 `ps aux | grep java | awk '/namesrv/{print $2}'`

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

fi

SRV_PORT="10911"                      ## 端口号

SRV_PROT="tcp"                        ## 协议类型

       RETVAL=`/usr/bin/nmap -n -s${PROT_OPT} -p ${SRV_PORT} ${ETH1_ADDR} | grep open`

       [[ -n "${RETVAL}" ]] && SCAN_FLAG=1;break || sleep 10

       [[ -n `ps aux | grep java | grep broker` ]] && kill -9 `ps aux | grep java | awk '/broker/{print $2}'`

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

fi

 

 

【注意】

以上红色标注部分，在master2上的名称为“broker-b.properties”

 

4、crontab信息添加

# touch /var/run/check_rocketmq_nameserver.lock

# touch /var/run/check_rocketmq_brokerserver.lock

 

# echo 'touch /var/run/check_rocketmq_nameserver.lock' >> /etc/rc.d/rc.local

# echo 'touch /var/run/check_rocketmq_brokerserver.lock' >> /etc/rc.d/rc.local

 

# crontab -e

*/2 * * * * (flock --timeout=0 /var/run/check_rocketmq_nameserver.lock /data/scripts/check_nameserver_health.sh >/dev/null 2>&1)

 

*/2 * * * * (flock --timeout=0 /var/run/check_rocketmq_brokerserver.lock /data/scripts/check_brokerserver_health.sh >/dev/null 2>&1)
