tips
檢驗java環境與maven環境
java -version
mvn -v
RocketMQ 的安裝包分為兩種,二進位制包和原始碼包,二進位制包是已經編譯完成後可以直接執行的,原始碼包是需要編譯後執行的。
rocketmq-all-5.0.0-ALPHA-bin-release.zip
原始碼包直接解壓
rocketmq-all-5.0.0-ALPHA-source-release.zip
二進位制包使用maven編譯
$ unzip rocketmq-all-5.0.0-source-release.zip
$ cd rocketmq-all-5.0.0-source-release/
$ mvn -Prelease-all -DskipTests clean install -U
$ cd distribution/target/rocketmq-5.0.0/rocketmq-5.0.0
### 啟動namesrv
$ nohup sh bin/mqnamesrv &
### 驗證namesrv是否啟動成功
$ tail -f ~/logs/rocketmqlogs/namesrv.log
The Name Server boot success...
我們可以在namesrv.log 中看到 'The Name Server boot success..', 表示NameServer 已成功啟動。
### 先啟動broker
$ nohup sh bin/mqbroker -n localhost:9876 &
### 驗證broker是否啟動成功, 比如, broker的ip是192.168.1.2 然後名字是broker-a
$ tail -f ~/logs/rocketmqlogs/Broker.log
The broker[broker-a,192.169.1.2:10911] boot success...
我們可以在 Broker.log 中看到「The broker[brokerName,ip:port] boot success..」,這表明 broker 已成功啟動。
在進行工具測試訊息收發之前,我們需要告訴使用者端NameServer的地址,RocketMQ有多種方式在使用者端中設定NameServer地址,這裡我們利用環境變數NAMESRV_ADDR
$ export NAMESRV_ADDR=localhost:9876
$ sh bin/tools.sh org.apache.rocketmq.example.quickstart.Producer
SendResult [sendStatus=SEND_OK, msgId= ...
$ sh bin/tools.sh org.apache.rocketmq.example.quickstart.Consumer
ConsumeMessageThread_%d Receive New Messages: [MessageExt...
1.下載專案
在 GitHub 中搜尋 rocketmq-externals,其中 rocketmq-console 就是 RocketMQ 視覺化控制檯,我們可以將原始碼克隆下來,然後自己 mvn package,然後執行 jar 包。
或者直接下載官方提供的 1.0.0 版本的 rocketmq-console
https://github.com/apache/rocketmq-externals/releases/tag/rocketmq-console-1.0.0
下載 zip 包或者 tar 包
修改組態檔application.properties
設定rocketmq.config.namesrvAddr屬性的值,即nameserver的服務地址
rocketmq.config.namesrvAddr=localhost:9876
儲存修改後的組態檔,返回rocketmq-console目錄
使用maven打包命令打包
mvn clean package -Dmaven.test.skip=true
打包完成後進入target目錄
rocketmq-console-ng-2.0.0.jar即為打包後得到的jar包
啟動程式
nohup java -jar rocketmq-console-ng-2.0.0.jar &
啟動 NameServer 和 broker
nohup sh bin/mqnamesrv >mqnamesrv-log.txt &
nohup sh bin/mqbroker -n 127.0.0.1:9876 >mqbroker-log.txt &
啟動控制檯
mvn spring-boot:run
建立一個 topic名為 test_quick_topic
工具測試完成後,我們可以嘗試使用 SDK 收發訊息。這裡以 Java SDK 為例介紹一下訊息收發過程。
在IDEA中建立一個Java工程。
在 pom.xml 檔案中新增以下依賴引入Java依賴庫。
