一、准备工作

1.设置hostname

[root@rabbitmq01 network-scripts]# hostnamectl set-hostname nameserver01
[root@rabbitmq01 network-scripts]# hostname
nameserver01

6台服务器均设置主机名,详见环境说明。

2.设置hosts

[root@nameserver01 ~]# cat >> /etc/hosts <<EOF
> 172.16.7.91  nameserver01  
> 172.16.7.92  nameserver02
> 172.16.7.93  master01
> 172.16.7.94  slave01
> 172.16.7.95  master02
> 172.16.7.96  slave02
> EOF

6台服务器都执行以上操作

3.关闭防火墙和selinux

详见Centos7.6操作系统安装及优化全纪录

二、安装jdk

1.下载jdk

下载地址:https://www.oracle.com/java/technologies/javase/javase-jdk8-downloads.html

image-20210601170259948

2.安装jdk

新建目录/opt/java并将下载的包jdk-8u291-linux-x64.rpm 上传

[root@nameserver01 ~]# mkdir /opt/java
[root@nameserver01 ~]# cd /opt/java
[root@nameserver01 java]# rpm -ivh jdk-8u291-linux-x64.rpm 

image-20210611100322574

6台都执行java安装

三、安装maven

6台服务器都执行如下操作

1.下载安装包

[root@nameserver01 ~]# wget https://mirrors.tuna.tsinghua.edu.cn/apache/maven/maven-3/3.6.3/binaries/apache-maven-3.6.3-bin.tar.gz

也可以到官网下载,下载地址:http://maven.apache.org/download.cgi

2.解压并配置环境变量

[root@nameserver01 ~]# tar -zxvf apache-maven-3.6.3-bin.tar.gz -C /usr/local/
[root@nameserver01 ~]# mv /usr/local/apache-maven-3.6.3/ /usr/local/maven3.6
[root@nameserver01 ~]# sed -i '$a export PATH=$PATH:/usr/local/maven3.6/bin' /etc/profile && source /etc/profile
[root@nameserver01 ~]# mvn -v

image-20210611101107969

3.maven优化

3.1配置阿里源

[root@rabbitmq01 ~]# cd /usr/local/maven3.6/conf/
[root@rabbitmq01 conf]# view settings.xml

修改前:

<url>http://my.repository.com/repo/path</url>

修改后:

<url>http://maven.aliyun.com/nexus/content/groups/public/</url>

image-20210602100342700

3.2指定资源下载路径

修改前:

<localRepository>/path/to/local/repo</localRepository>

修改后:

<localRepository>/usr/local/maven3.6/repository</localRepository>

image-20210602100624371

3.3指定JDK版本

将默认的1.4替换为实际的1.8

修改前:

image-20210602100754413

修改后:

image-20210602100902226

四、RocketMQ安装

1.版本选取

下载地址:https://github.com/apache/rocketmq/tags

image-20210601162652495

本次选择的版本为最新的4.8.0

2.下载安装包

[root@nameserver01 ~]# wget https://github.com/apache/rocketmq/archive/refs/tags/rocketmq-all-4.8.0.tar.gz

image-20210611101809418

3.解压并编译

[root@nameserver01 ~]# mkdir /rocketmq
[root@nameserver01 ~]# tar -zxvf rocketmq-all-4.8.0.tar.gz -C /rocketmq
[root@nameserver01 ~]# mv /rocketmq/rocketmq-rocketmq-all-4.8.0/* /rocketmq/ && rm -rf /rocketmq/rocketmq-rocketmq-all-4.8.0/
[root@nameserver01 ~]# cd /rocketmq/
[root@nameserver01 rocketmq]# mvn -Prelease-all -DskipTests clean install -U

image-20210611103522494

中间省略了些步骤

image-20210611103433336

4.免编译安装

除了使用maven编译安装方式外,还可以直接下载带bin的安装包,免编译安装,步骤3和步骤4执行一个就行。

本文后面章节基于免编译安装。

下载地址:https://apache.claz.org/rocketmq/4.8.0/rocketmq-all-4.8.0-bin-release.zip

[root@nameserver01 ~]# cd /rocketmq/
[root@nameserver01 rocketmq]# wget https://apache.claz.org/rocketmq/4.8.0/rocketmq-all-4.8.0-bin-release.zip
[root@nameserver01 rocketmq]# unzip rocketmq-all-4.8.0-bin-release.zip
[root@nameserver01 rocketmq]# cd rocketmq-all-4.8.0-bin-release && mv * /rocketmq/ && rm -rf /rocketmq/rocketmq-all-4.8.0-bin-release*
[root@nameserver01 rocketmq]# pwd
/rocketmq
[root@nameserver01 rocketmq]# ll
总用量 40
drwxr-xr-x 2 root root   102 12月  9 19:46 benchmark
drwxr-xr-x 3 root root  4096 12月  4 14:26 bin
drwxr-xr-x 6 root root   211 12月  4 14:26 conf
drwxr-xr-x 2 root root  4096 12月  9 19:46 lib
-rw-r--r-- 1 root root 17336 10月 23 2020 LICENSE
-rw-r--r-- 1 root root  1338 12月  4 14:26 NOTICE
-rw-r--r-- 1 root root  5132 12月  4 14:26 README.md

rocketmq-all-4.8.0-bin-release.zip带bin版本的介质无需maven编译,解压后即可使用。

5.配置环境变量

[root@nameserver01 ~]# sed -i '$a export ROCKETMQ_HOME=/rocketmq' /etc/profile
[root@nameserver01 ~]# sed -i '$a export PATH=$PATH:$ROCKETMQ_HOME/bin' /etc/profile && source /etc/profile

image-20210611170252130

五、Name Server集群安装

本节操作在nameserver集群nameserver01和nameserver02都执行。

1.调整runserver.sh参数

[root@nameserver01 ~]# cd /rocketmq/bin/
[root@nameserver01 bin]# view runserver.sh 

调整前:

JAVA_OPT="${JAVA_OPT} -server -Xms4g -Xmx4g -Xmn2g -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m"

调整后:

JAVA_OPT="${JAVA_OPT} -server -Xms256m -Xmx256m -Xmn128m -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m"

由于默认启动的最大内存比较大,在虚机测试时需要修改小点保证服务能正常启动。

2.启动NameServer

[root@nameserver01 bin]# nohup sh mqnamesrv &

image-20210611172311030

NameServer启动成功,同样的nameserver02也执行相同启动命令。

六、Broker集群安装

本节操作在Broker集群master01、slave01、master02、slave02分别执行。

1.调整runbroker.sh参数

[root@master01 ~]# cd /rocketmq/bin
[root@master01 bin]# view runbroker.sh 

调整前:

JAVA_OPT="${JAVA_OPT} -server -Xms8g -Xmx8g -Xmn4g"

调整后:

JAVA_OPT="${JAVA_OPT} -server -Xms256m -Xmx256m -Xmn128m"

由于默认启动的最大内存比较大,在虚机测试时需要修改小点保证服务能正常启动。

2.配置broker

由于本文采用的是2主2从同步方式,对应的目录为2m-2s-sync

[root@master01 2m-2s-sync]# pwd
/rocketmq/conf/2m-2s-sync
[root@master01 2m-2s-sync]# ll
总用量 16
-rw-r--r-- 1 root root 928 10月 23 2020 broker-a.properties
-rw-r--r-- 1 root root 922 10月 23 2020 broker-a-s.properties
-rw-r--r-- 1 root root 928 10月 23 2020 broker-b.properties
-rw-r--r-- 1 root root 922 10月 23 2020 broker-b-s.properties

2.1修改master01配置broker-a.properties

[root@master01 2m-2s-sync]# pwd
/rocketmq/conf/2m-2s-sync
[root@master01 2m-2s-sync]# more broker-a.properties 
namesrvAddr=172.16.7.91:9876;172.16.7.92:9876
brokerClusterName=MyRocketmq
brokerName=broker-a
brokerId=0
deleteWhen=04
fileReservedTime=48
brokerRole=SYNC_MASTER
flushDiskType=ASYNC_FLUSH

新增了namesrvAddr,指定对应的ip和端口;修改了brokerClusterName,自定义集群名为MyRocketmq;刷盘方式为默认的ASYNC_MASTER即异步方式。

2.2修改slave01配置broker-a-s.properties

[root@slave01 2m-2s-sync]# more broker-a-s.properties
namesrvAddr=172.16.7.91:9876;172.16.7.92:9876
brokerClusterName=MyRocketmq
brokerName=broker-a
brokerId=1
deleteWhen=04
fileReservedTime=48
brokerRole=SLAVE
flushDiskType=ASYNC_FLUSH

2.3修改master02配置broker-b.properties

[root@master02 2m-2s-sync]# more broker-b.properties
namesrvAddr=172.16.7.91:9876;172.16.7.92:9876
brokerClusterName=MyRocketmq
brokerName=broker-b
brokerId=0
deleteWhen=04
fileReservedTime=48
brokerRole=SYNC_MASTER
flushDiskType=ASYNC_FLUSH

2.4修改slave02配置broker-b-s.properties

[root@slave02 2m-2s-sync]# more broker-b-s.properties
namesrvAddr=172.16.7.91:9876;172.16.7.92:9876
brokerClusterName=MyRocketmq
brokerName=broker-b
brokerId=1
deleteWhen=04
fileReservedTime=48
brokerRole=SLAVE
flushDiskType=ASYNC_FLUSH

3.启动broker

3.1启动master01

[root@master01 rocketmq]# pwd
/rocketmq
[root@master01 rocketmq]# nohup sh bin/mqbroker -c conf/2m-2s-sync/broker-a.properties &

image-20210611172415497

master01节点启动成功

3.2启动slave01

[root@slave01 rocketmq]# pwd
/rocketmq
[root@slave01 rocketmq]# nohup sh bin/mqbroker -c conf/2m-2s-sync/broker-a-s.properties &

image-20210611180018178

slave01启动成功

3.3启动master02

[root@master02 rocketmq]# pwd
/rocketmq
[root@master02 rocketmq]# nohup sh bin/mqbroker -c conf/2m-2s-sync/broker-b.properties &

image-20210611172452728

master02启动成功

3.4启动slave02

[root@slave02 rocketmq]# pwd
/rocketmq
[root@slave02 rocketmq]# nohup sh bin/mqbroker -c conf/2m-2s-sync/broker-b-s.properties &

image-20210611172510609

slave02启动成功

七、安装管理面板

本节在nameserver01上执行

1.介质下载

git下载介质

[root@nameserver01 ~]# yum -y install git
[root@nameserver01 ~]# git clone https://github.com/apache/rocketmq-externals.git

或者下载到本地再上传,下载地址:https://github.com/apache/rocketmq-externals/archive/refs/heads/master.zip

这里选择先下载再上传方式

2.解压

[root@nameserver01 ~]# unzip rocketmq-externals-master--console.zip 
[root@nameserver01 ~]# cd rocketmq-externals-master

image-20210611173616087

3.修改配置文件

[root@nameserver01 resources]# pwd
/root/rocketmq-externals-master/rocketmq-console/src/main/resources
[root@nameserver01 resources]# view application.properties

image-20210611174000379

自定义应用端口和nameserver服务器

4.编译

[root@nameserver01 rocketmq-console]# pwd
/root/rocketmq-externals-master/rocketmq-console
[root@nameserver01 rocketmq-console]# mvn clean package -Dmaven.test.skip=true
[INFO] Scanning for projects...

image-20210611174810590

编译过程如图,中间过程省略

image-20210611174735373

编译成功,console目录下会生成target目录

5.运行

[root@nameserver01 rocketmq-console]# pwd
/root/rocketmq-externals-master/rocketmq-console
[root@nameserver01 rocketmq-console]# cd target/
[root@nameserver01 target]# java -jar rocketmq-console-ng-1.0.1.jar

image-20210615143747490

6.访问console

访问地址:http://172.16.7.91:57690

image-20210615150135262

image-20210615150120075

八、集群测试

1.生产者

nameserver01上执行生产者测试

[root@nameserver01 rocketmq]# export NAMESRV_ADDR='172.16.7.91:9876;172.16.7.92:9876'
[root@nameserver01 rocketmq]# sh bin/tools.sh org.apache.rocketmq.example.quickstart.Producer

image-20210615151552972

2.消费者

nameserve02上执行消费者测试

[root@nameserver02 rocketmq]# export NAMESRV_ADDR='172.16.7.91:9876;172.16.7.92:9876'
[root@nameserver02 rocketmq]# sh bin/tools.sh org.apache.rocketmq.example.quickstart.Consumer
