2.下载和构建
下载 4.2.0 源代码版本地址http://mirrors.hust.edu.cn/apache/rocketmq/4.2.0/rocketmq-all-4.2.0-source-release.zip
现在执行以下命令来解压缩 4.2.0 源代码版本并构建二进制工件。 unzip rocketmq-all-4.2.0-source-release.zip cd rocketmq-all-4.2.0/ mvn -Prelease-all -DskipTests clean install -U cd distribution/target/apache-rocketmq
3.启动mqnamesrv 、mqbroker nohup sh bin/mqnamesrv tail -f ~/logs/rocketmqlogs/namesrv.log运行成功的日志输出The Name Server boot success...官方启动 broker 方式如下 nohup sh bin/mqbroker -n localhost:9876
经测试这样是不行的要在后面加上设置 : autoCreateTopicEnabletrue 。最终运行命令为nohup 记录日志 表示后台运行 nohup sh mqbroker -n localhost:9876 autoCreateTopicEnabletrue tail -f ~/logs/rocketmqlogs/broker.log 运行成功的日志输出The broker[%s, 172.30.30.233:10911] boot success... 4.修改配置、发送和接收消息
设置环境变量 export NAMESRV_ADDRlocalhost:9876启动生产者 sh bin/tools.sh org.apache.rocketmq.example.quickstart.ProducerSendResult [sendStatusSEND_OK, msgId ...启动消费者 sh bin/tools.sh org.apache.rocketmq.example.quickstart.ConsumerConsumeMessageThread_%d Receive New Messages: [MessageExt...5.关闭服务 sh bin/mqshutdown broker运行成功时日志输出
The mqbroker(36695) is running...
Send shutdown request to mqbroker(36695) OK sh bin/mqshutdown namesrv运行成功时日志输出
The mqnamesrv(36664) is running...
Send shutdown request to mqnamesrv(36664) OK
