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；
本文采用双Master的架构模式。
二、服务器分布
1、相关说明
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 6.30
4、总体架构

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
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 &
|
(2)、启动BrokerServer A【master1】
# cd /usr/local/rocketmq/bin
# nohup sh mqbro ker -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
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 |
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)
