Centos7下基于jdk11 安装RocketMQ

1、简介

RocketMQ是阿里巴巴中间件团队自研的一款高性能、高吞吐量、低延迟、高可用、高可靠（具备金融级稳定性）的分布式消息中间件，开源后并于2016年捐赠给Apache社区孵化，目前已经成为了
Apache顶级项目。当前在国内被广泛的使用。

github:https://github.com/apache/rocketmq
官网：https://rocketmq.apache.org/

2、准备环境

• JDK 11.0.5 (以下活官方获取)
  链接：https://pan.baidu.com/s/1hEtgH16mEAMWRYiUGnXWUw?pwd=261i
  提取码：261i
• Linux centos7 5.4.231-1.el7.elrepo.x86_64
• 源码安装需要安装Maven 3.2.x
• RocketMQ最新版本：4.5.1

3、安装及启动

1. 下载

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

1. 配置环境变量vim /etc/profile 并且 刷新配置 source /etc/profile

# JAVA_HOME需要配置成自己的安装路径
export JAVA_HOME=/usr/local/jdk-11.0.18 (你的目录)
export JRE_HOME=${JAVA_HOME}/jre
export CLASSPATH=.:${JAVA_HOME}/lib:${JRE_HOME}/lib:$CLASSPATH
export JAVA_PATH=${JAVA_HOME}/bin:${JRE_HOME}/bin
export PATH=$PATH:${JAVA_PATH}
#mvn
MAVEN_HOME=/usr/local/apache-maven-3.9.0 (你的目录)
PATH=$MAVEN_HOME/bin:$PATH
export MAVEN_HOME PATH
#rockemq
export ROCKET_HOME=/usr/local/rocketmq-4.5.1 (你的目录)
export PATH=$PATH:${ROCKET_HOME}/bin

1. 修改脚本
   你的下载安装目录 xxxx/rocketmq/bin

bin/runserver.sh
bin/runbroker.sh
bin/tools.sh

• 修改runserver.sh vim rocketmq-4.5.1/bin/runserver.sh

删除
UseCMSCompactAtFullCollection
UseParNewGC
UseConcMarkSweepGC
修改内存：
JAVA_OPT=“${JAVA_OPT} -server -Xms256m -Xmx256m -Xmn128m -
XX:MetaspaceSize=64mm -XX:MaxMetaspaceSize=160mm”
-Xloggc修改为-Xlog:gc

1. 启动NameServer

先启动NameServer在启动Broker

# 1.启动NameServer
mqnamesrv
# 2.查看启动日志
tail -f ~/logs/rocketmqlogs/namesrv.log

1. 启动Broker

# 1.启动Broker
mqbroker -n localhost:9876
# 2.查看启动日志
tail -f ~/logs/rocketmqlogs/broker.log

4 环境测试（浅玩）

• 发送消息 与接收消息
• 启动消费者

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

• 启动生产者

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