rocketMQ学习笔记一：RocketMQ安装部署

官网链接:rocketmq-apache-org

---

一、环境要求

• 推荐64bit OS, Linux/Unix/Mac;（32位会有问题，用64位系统少采坑）
• 64bit JDK 1.8+;
• Maven 3.2.x;
• Git;
• 4g+ free disk for Broker server

二、下载、构建

// 下载
curl -O --insecure http://mirror.bit.edu.cn/apache/rocketmq/4.4.0/rocketmq-all-4.4.0-source-release.zip
// 解压
unzip rocketmq-all-4.4.0-source-release.zip
// 进入解压后的项目目录
cd rocketmq-all-4.4.0/
// 构建并安装到本地仓库
mvn -Prelease-all -DskipTests clean install -U
// 进入
cd distribution/target/apache-rocketmq

drwxr-xr-x  29 gongninggang  staff   928B  5  8 15:43 lib/

三、 启动NameServer

// 后台启动NameServer
nohup sh bin/mqnamesrv &
// 查看日志
tail -f ~/logs/rocketmqlogs/namesrv.log

四、启动Broker

nohup sh bin/mqbroker -n localhost:9876 &
tail -f ~/logs/rocketmqlogs/broker.log

五、发送和接收消息

在发送和接收消息之前，首先需要告诉客户端“Name Server”所在的位置。方式有很多。本文使用环境变量的方式。

// 添加环境变量
export NAMESRV_ADDR=localhost:9876
// 生产消息
sh bin/tools.sh org.apache.rocketmq.example.quickstart.Producer

// 消费消息
sh bin/tools.sh org.apache.rocketmq.example.quickstart.Consumer

六、启动rocketmq-console控制台

java -jar /Users/gongninggang/source/rocketmq-externals/rocketmq-console/target/rocketmq-console-ng-1.0.1.jar

七、mqadmin使用

// 进入bin目录
cd /Users/gongninggang/rocketmq-all-4.4.0/distribution/target/apache-rocketmq/bin
// 查看mqadmin有哪些操作
GNGMacBook-Pro:bin gongninggang$ sh mqadmin
// 查看命令的帮助
GNGMacBook-Pro:bin gongninggang$ sh mqadmin help topicList

Java HotSpot(TM) 64-Bit Server VM warning: ignoring option MaxPermSize=128m; support was removed in 8.0
usage: mqadmin topicList [-c] [-h] [-n <arg>]

//

// 查看TOPIC列表
GNGMacBook-Pro:bin gongninggang$ sh mqadmin topicList -n '172.16.173.191:9876'

八、关闭服务

cd /Users/gongninggang/rocketmq-all-4.4.0/distribution/target/apache-rocketmq
// 关闭broker
sh bin/mqshutdown broker
// 关闭namesrv
sh bin/mqshutdown namesrv
