环境需要

64位操作系统，建议使用Linux / Unix /

• CentOs7.3
• 64bit JDK 1.8+
• Maven 3.2.x

JDK Maven 的安装自行 Google 或者去我博客 搜索安装

下载和构建

下载4.2.0源码版本:

下载4.2.0二进制版本:

现在执行以下命令来解压4.2.0源码版本并构建二进制文件

& unzip rocketmq-all-4.2.0-source-release.zip& cd rocketmq-all-4.2.0/& mvn -Prelease-all -DskipTests clean install -U& mv distribution/target/apache-rocketmq /opt/apache-rocketmq

Start Name Server

默认 RocketMQ Server 内存需要很大的

vi /bin/runserver.sh

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

我修改成

JAVA_OPT="${JAVA_OPT} -server -Xms1g -Xmx1g -Xmn512m -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m"

& cd /opt/apache-rocketmq& nohup sh bin/mqnamesrv > /dev/null 2>&1 && tail -f ~/logs/rocketmqlogs/namesrv.log

会看到如下响应信息

2018-02-01 16:15:16 INFO main - The Name Server boot success...

Start Broker

默认 RocketMQ Broker 内存需要很大的

vi /bin/runbroker.sh

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

我修改成

JAVA_OPT="${JAVA_OPT} -server -Xms1g -Xmx1g -Xmn512m"

启动Broker

& nohup sh bin/mqbroker -n localhost:9876 > /dev/null 2>&1 && tail -f ~/logs/rocketmqlogs/broker.log

会看到如下响应信息

2018-02-01 17:37:48 INFO main - The broker[node1, 192.168.252.121:10911] boot success...

发送并接受 消息

Send & Receive Messages

发送消息

发送/接收消息之前,我们需要告诉客户端 NameServer 地址。RocketMQ 提供了多种方式来实现这一目标。为简单起见,我们使用环境变量 NAMESRV_ADDR。

export NAMESRV_ADDR=localhost:9876sh bin/tools.sh org.apache.rocketmq.example.quickstart.Producer

响应

SendResult [sendStatus=SEND_OK, msgId= ...

消费消息

sh bin/tools.sh org.apache.rocketmq.example.quickstart.Consumer

响应

ConsumeMessageThread_%d Receive New Messages: [MessageExt...

停止服务

停止 broker

> sh bin/mqshutdown brokerThe mqbroker(36695) is running...Send shutdown request to mqbroker(36695) OK

停止 namesrv

> sh bin/mqshutdown namesrvThe mqnamesrv(36664) is running...Send shutdown request to mqnamesrv(36664) OK
