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；

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

三、RocketMQ安装与配置

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

1、JDK安装

http://download.oracle.com/otn-pub/java/jdk/7u65-b17/jdk-7u65-linux-x64.tar.gz

# 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

https://github.com/alibaba/RocketMQ/releases

# 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

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 &

(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
PATH=/sbin:/bin:/usr/sbin:/usr/bin:/usr/local/bin:/usr/local/sbin

SRV_PORT="9876"                    ## 端口号
SRV_PROT="tcp"                     ## 协议类型
SRV_NAME="rocketmq_nameserver"     ## 服务名

## 是否已正确扫描
SCAN_FLAG=0

for ETH_NAME in `/sbin/ifconfig | grep eth1 | awk '{print $1}'`
do
ETH1_ADDR=`/sbin/ifconfig ${ETH_NAME} | awk -F ':' '/inet addr/{print $2}' | sed 's/[a-zA-Z ]//g'`
[[ -z "${ETH1_ADDR}" ]] && continue || break
done

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


3、brokerserver监控

# vim /data/scripts/check_brokerserver_health.sh

#!/bin/sh
PATH=/sbin:/bin:/usr/sbin:/usr/bin:/usr/local/bin:/usr/local/sbin

SRV_PORT="10911"                      ## 端口号
SRV_PROT="tcp"                        ## 协议类型
SRV_NAME="rocketmq_brokerserver"      ## 服务名

## 是否已正确扫描
SCAN_FLAG=0

for ETH_NAME in `/sbin/ifconfig | grep eth1 | awk '{print $1}'`
do
ETH1_ADDR=`/sbin/ifconfig ${ETH_NAME} | awk -F ':' '/inet addr/{print $2}' | sed 's/[a-zA-Z ]//g'`
[[ -z "${ETH1_ADDR}" ]] && continue || break
done

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 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)
