RocketMQ安装

Posted 2023-02-27 Lossdate

一、 环境

1. RocketMQ: 4.5.1
   https://www.apache.org/dyn/closer.cgi?path=rocketmq/4.5.1/rocketmq-all-4.5.1-bin-release.zip

二、安装

1. 下载rocketmq
   4.5.1

   wget https://archive.apache.org/dist/rocketmq/4.5.1/rocketmq-all-4.5.1-bin-release.zip
   

2. 解压

   unzip rocketmq-all-4.5.1-bin-release.zip -d /opt
   cd /opt/
   mv rocketmq-all-4.5.1-bin-release/rocketmq
   cd rocketmq/
   

3. 配置环境变量

   vim /etc/profile
   
   export ROCKET_HOME=/opt/rocketmq
   export PATH=$PATH:$ROCKET_HOME/bin
   

4. 生效配置

   . /etc/profile
   

5. 修改脚本
   rocketmq默认需要4G空间，虚拟机搭建可以修改小点
   bin/runserver.sh
   bin/runbroker.sh
   例：

   #虚拟机内存比较小，由4G改为256M
   JAVA_OPT="$JAVA_OPT -server -Xms256m -Xmx256m -Xmn128m -XX:MetaspaceSize=64mm -XX:MaxMetaspaceSize=160mm"
   

   jdk如果是8以上，则需要修改以下脚本
   1）bin/runserver.sh

   cd /opt/rocketmq/
   vim bin/runserver.sh
   
   #删除 
   UseCMSCompactAtFullCollection 
   UseParNewGC 
   UseConcMarkSweepGC
   #虚拟机内存比较小，由4G改为256M
   JAVA_OPT="$JAVA_OPT -server -Xms256m -Xmx256m -Xmn128m -XX:MetaspaceSize=64mm -XX:MaxMetaspaceSize=160mm"
   -Xloggc修改为-Xlog:gc
   

   2）bin/runbroker.sh

   cd /opt/rocketmq/
   vim bin/runbroker.sh
   
   #删除
   PrintGCDateStamps 
   PrintGCApplicationStoppedTime 
   PrintAdaptiveSizePolicy 
   UseGCLogFileRotation 
   NumberOfGCLogFiles=5 
   GCLogFileSize=30m
   

   3）bin/tools.sh

   cd /opt/rocketmq/
   vim bin/tools.sh
   
   #删除 
   JAVA_OPT="$JAVA_OPT -Djava.ext.dirs=$BASE_DIR/lib:$JAVA_HOME/jre/lib/ext"
   

6. 测试（jdk8以上测试修改脚本）

   mqnamesrv
   

   

   mqbroker -n localhost:9876
   

   

7. 启动

   #启动NameServer 
   mqnamesrv 
   
   #新开窗口
   #启动Broker 
   mqbroker -n localhost:9876 
   

8. 启用SQL92消息过滤 （可选）

   cd /opt/rocketmq/conf/
   vim broker.conf
   #启用SQL92消息过滤
   enablePropertyFilter=true
   
   #生效配置
   mqbroker -c /opt/rocketmq/conf/broker.conf -p | grep -i propertyfilter
   #启动broker
   mqbroker -n localhost:9876 -c /opt/rocketmq/conf/broker.conf 
   

三、RocketMQ环境测试

1. 接收消息

   #设置环境变量 
   export NAMESRV_ADDR=localhost:9876 
   #接收消息 
   sh bin/tools.sh org.apache.rocketmq.example.quickstart.Consumer
   

   
2. 发送消息

   #设置环境变量 
   export NAMESRV_ADDR=localhost:9876 
   #使用安装包的Demo发送消息
   sh bin/tools.sh org.apache.rocketmq.example.quickstart.Producer
   

3. 关闭

   #依次停止broker和namesrv
   mqshutdown broker
   mqshutdown namesrv
   

4. etc

   #查看主题
   mqadmin topicList -n localhost:9876
   #创建主题
   mqadmin updateTopic -n localhost:9876 -b localhost:10911 -t tp_demo -w 6
   #查看broker名
   mqbroker -p
   #创建主题，8写8读
   mqadmin updateTopic -b nodeA:10911 -n localhost:9876 -r 8 -t tp_demo -w 8
   #删除主题的操作
   mqadmin deleteTopic -c DefaultCluster deleteTopic -n localhost:9876 -t tp_demo
   #主题描述
   mqadmin topicStatus -n localhost:9876 -t tp_demo
   

四、可视化工具 rocketmq-console

1. 下载地址
   https://github.com/apache/rocketmq-externals/archive/rocketmq-console-1.0.0.zip
2. 编译
   IDEAD导入，JDK选择1.8
   properties修改namesrvAddr

   rocketmq.config.namesrvAddr=nodeA:9876
   

   打包

   mvn clean package -DskipTests
   

3. 启动
   通过cmd启动

   java -jar rocketmq-console-ng-1.0.0.jar
   

   访问http://localhost:8080/
