1、下载安装
RocketMQ 的安装包分为两种，二进制包和源码包。1 下载 Apache RocketMQ 5.3.1的源码包后上传到linux
https://dist.apache.org/repos/dist/release/rocketmq/5.3.1/rocketmq-all-5.3.1-source-release.zip2 解压编译
$ unzip rocketmq-all-5.3.1-source-release.zip
$ cd rocketmq-all-5.3.1-source-release/
$ mvn -Prelease-all -DskipTests -Dspotbugs.skip=true clean install -U编译需要好几分钟

benchmark bin conf lib LICENSE NOTICE README.md2 修改启动参数
2.1修改broker的运行脚本，内存不够可以适当的修改broker启动参数[root@localhost bin]# pwd
/usr/local/software/rocketmq-all-5.3.1-source-release/distribution/target/rocketmq-5.3.1/rocketmq-5.3.1/bin[root@localhost bin]# vim runbroker.sh
ESC: set number 可以显示行数找到如下参数：-server -Xms8g -Xmx8g 看着改，只要能启动就行
改成 -server -Xms2g -Xmx2g
改成-server -Xms1g -Xmx1g
改成-server -Xms256m -Xmx256m101 choose_gc_log_directory
103 JAVA_OPT="${JAVA_OPT} -server -Xms8g -Xmx8g"2.2 修改nameServer的运行脚本, 修改89和94行-server -Xms4g -Xmx4g -Xmn2g
看着改，只要能启动就行
改成-server -Xms1g -Xmx1g -Xmn512m
改成-server -Xms2g -Xmx2g -Xmn1g
改成-server -Xms256m -Xmx256m -Xmn128m89 JAVA_OPT="${JAVA_OPT} -server -Xms4g -Xmx4g -Xmn2g -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m"90 JAVA_OPT="${JAVA_OPT} -XX:+UseConcMarkSweepGC -XX:+UseCMSCompactAtFullCollection -XX:CMSInitiatingOccupancyFraction=70 -XX:+CMSParallelRemarkEnabl ed -XX:SoftRefLRUPolicyMSPerMB=0 -XX:+CMSClassUnloadingEnabled -XX:SurvivorRatio=8 -XX:-UseParNewGC"91 JAVA_OPT="${JAVA_OPT} -verbose:gc -Xloggc:${GC_LOG_DIR}/rmq_srv_gc_%p_%t.log -XX:+PrintGCDetails -XX:+PrintGCDateStamps"92 JAVA_OPT="${JAVA_OPT} -XX:+UseGCLogFileRotation -XX:NumberOfGCLogFiles=5 -XX:GCLogFileSize=30m"93 else94 JAVA_OPT="${JAVA_OPT} -server -Xms4g -Xmx4g -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m"2.3 修改代理的端口默认是8080和8081修改成9080和9081，要不然8080可能会和tomcat的端口冲突
[root@localhost conf]# vi rmq-proxy.json
{"rocketMQClusterName": "DefaultCluster","remotingListenPort": 9080,"grpcServerPort": 9081
}3 修改broker的配置文件，设置可以自动创建主题。
进入conf目录下，修改broker.conf文件[root@localhost conf]# pwd
/usr/local/software/rocketmq-all-5.3.1-source-release/distribution/target/rocketmq-5.3.1/rocketmq-5.3.1/conf[root@localhost conf]# vim broker.conf
autoCreateTopicEnable=trueautoCreateTopicEnable：自动创建主题，不然需要手动创建出来
namesrvAddr：nameSrv地址可以写localhost因为nameSrv和broker在一个服务器，也可以用参数指定4 创建日志目录
/usr/local/software/rocketmq-all-5.3.1-source-release/distribution/target/rocketmq-5.3.1/rocketmq-5.3.1/
mkdir logs5 启动NameServer后台模式启动，进入到bin目录，执行如下命令，如果不想后台启动的话就进入bin目录后./mynamesrv
/usr/local/software/rocketmq-all-5.3.1-source-release/distribution/target/rocketmq-5.3.1/rocketmq-5.3.1/5.1 需要先启动Name Server
nohup sh bin/mqnamesrv > ./logs/namesrv.log &#!/bin/bash
nohup sh bin/mqnamesrv > ./logs/namesrv.log &
nohup sh bin/mqbroker -c conf/broker.conf -n 192.168.150.50:9876 --enable-proxy> ./logs/broker.log&
exit 0[root@localhost rocketmq-5.3.1]# nohup sh bin/mqnamesrv > ./logs/namesrv.log &5.2 查看日志
[root@localhost rocketmq-5.3.1]# cat logs/namesrv.logJava HotSpot(TM) 64-Bit Server VM warning: Using the DefNew young collector with the CMS collector is deprecated and will likely be removed in a future release

The Name Server boot success. serializeType=JSON, address 0.0.0.0:98766、启动Broker+Proxy
NameServer成功启动后，我们启动Broker和Proxy。这里我们使用 Local 模式部署，即 Broker 和 Proxy 同进程部署
进入到bin目录先启动broker
nohup sh bin/mqbroker -c conf/broker.conf -n 192.168.150.50:9876 --enable-proxy> ./logs/broker.log&[root@localhost rocketmq-5.3.1]# nohup sh bin/mqbroker -c conf/broker.conf -n 192.168.150.50:9876 --enable-proxy> ./logs/broker.log&也可以指定配置文件-c conf/broker.conf，用-pc conf/proxyConfig.json来改默认占用的8080和8081端口，改端口看下面的备注。 nohup bin/mqbroker -n 127.0.0.1:9876 -pc conf/proxyConfig.json --enable-proxy &nohup sh bin/mqbroker -c conf/broker.conf -n 192.168.150.50:9876 --enable-proxy> ./logs/broker.log&
[root@localhost logs]# cat broker.log
Thu Oct 24 15:17:52 CST 2024 rocketmq-proxy startup successfullyhttp://localhost:9999/rocketmq/send[root@localhost logs]# cat broker.log
Unrecognized VM option 'UseBiasedLocking'
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.Jdk21偏向锁被废弃了，移除这个VM参数
打开rocketmq 的/bin/runbroker.sh，移除UseBiasedLocking参数。JAVA_OPT="${JAVA_OPT} -XX:-UseLargePages -XX:-UseBiasedLocking"或许出现的其他问题
RocketMQ连接异常sendDefaultImpl call timeout装并启动好RocketMQ后，在代码中远程连接RocketMQ，报以下错误：org.apache.rocketmq.remoting.exception.RemotingTooMuchRequestException:sendDefaultImpl call timeout at org.apache.rocketmq.client.impl.producer.DefaultMQProducerImpl.sendDefaultImpl(DefaultMQProducerImpl.java:588)at org.apache.rocketmq.client.impl.producer.DefaultMQProducerImpl.send(DefaultMQProducerImpl.java:1223)at org.apache.rocketmq.client.impl.producer.DefaultMQProducerImpl.send(DefaultMQProducerImpl.java:1173)at org.apache.rocketmq.client.producer.DefaultMQProducer.send(DefaultMQProducer.java:214)at com.flying.demo.Producer.main(Producer.java:25)这个错误其实是启动RocketMQ的namesrv，broker没有指IP。
假如IP是：192.168.1.135
那么启动namesrv时，用以下方法：
nohup sh bin/mqnamesrv -n "192.168.1.135:9876" &
启动broker时，用以下方法：
修改conf/broker.conf，加入：brokerIP1=192.168.1.135
启动：nohup ./bin/mqbroker -n localhost:9876 -c conf/broker.conf autoCreateTopicEnable=true &备注：启动失败如果是8080端口已经绑定可以修改端口 ========================RocketMQ5.0.0 版本增加了 Proxy 模块，启动时默认会用到 8081 端口，当端口被占用时，broker/proxy 将无法启动，修改 proxy 端口方法如下：（1）在 conf 目录下修改rmq-proxy.json 文件，注意文件格式为 json，所以内容须为 json 格式；private int remotingListenPort = 8080;private Integer grpcServerPort = 8081;{// 代理监听端口"remotingListenPort": 9080,// gRPC服务器端口"grpcServerPort": 9081,// 对应namesr的ip，这个单机的时候可以不用加，集群的没测试过"namesrvAddr":"123.45.67.891:6789;198.76.54.321:6789"
}修改代理的端口默认是8080和8081
[root@localhost conf]# vi rmq-proxy.json
{"rocketMQClusterName": "DefaultCluster","remotingListenPort": 9080,"grpcServerPort": 9081
}=================================================================7. 关闭服务器和开机自启
进入到/usr/local/software/rocketmq-all-5.3.1-source-release/distribution/target/rocketmq-5.3.1/rocketmq-5.3.1/目录执行sh bin/mqshutdown namesrv
sh bin/mqshutdown broker8 使用代码测试[root@localhost bin]# sh mqadmin updateTopic -n 192.168.150.50:9876 -b 192.168.150.50:10911 -t MyTopic -w 4 -r 4create topic to 192.168.150.50:10911 success.

-b 192.168.150.50:10911：Broker地址。
-t MyTopic：主题名称。
-w 4：写队列数量。
-r 4：读队列数量。下面的内容还没测试到9 测试
在进行工具测试消息收发之前，我们需要告诉客户端NameServer的地址，RocketMQ有多种方式在客户端中设置NameServer地址，这里我们利用环境变量NAMESRV_ADDR
export NAMESRV_ADDR=localhost:9876
