1、下载RocketMQ
编译后的压缩包
wget https://dlcdn.apache.org/rocketmq/4.9.2/rocketmq-all-4.9.2-bin-release.zip
2、解压
unzip rocketmq-all-4.9.2-bin-release.zip
3、进入解压文件夹
cd rocketmq-all-4.9.2/
4、编辑配置文件/usr/local/rocketmq/rocketmq-all-4.9.4-bin-release/conf/broker.conf
如果不指定目录，则默认保存在 启动用户(如root) 则在/root/store 目录下面， 整个文件可删除，不影响
brokerClusterName = DefaultCluster
brokerName = broker-a
brokerId = 0
deleteWhen = 04
fileReservedTime = 48
brokerRole = ASYNC_MASTER
flushDiskType = ASYNC_FLUSH
##自动创建Topic
autoCreateTopicEnable=true
## # nameServ地址（你的服务器地址）
namesrvAddr=127.0.0.1:9876
brokerIP1=127.0.0.1
## 存储路径
storePathRootDir=/usr/local/rocketmq/rocketmq-all-4.9.4-bin-release/data/
## commitLog路径
storePathCommitLog=/usr/local/rocketmq/rocketmq-all-4.9.4-bin-release/commitlog
## 消息队列存储路径
storePathConsumeQueue=/usr/local/rocketmq/rocketmq-all-4.9.4-bin-release/data/consumequeue
## 消息索引存储路径
storePathIndex=/usr/local/rocketmq/rocketmq-all-4.9.4-bin-release/data/index
## checkpoint文件路径
storeCheckpoint=/usr/local/rocketmq/rocketmq-all-4.9.4-bin-release/data/checkpoint
## abort文件存储路径
abortFile=/usr/local/rocketmq/rocketmq-all-4.9.4-bin-release/data/abort
5、配置占用内存大小
修改booker、server、tools里边配置的占用内存大小
6、配置开机自启
目录：/usr/lib/systemd/system

开启开机自启
systemctl daemon-reload
systemctl start rocketmqname.service
systemctl start rocketmqbroker.service
systemctl enable rocketmqname.service
systemctl enable rocketmqbroker.service
注意：需要开放 10911、10909、9876、8888 端口
注意2：Jdk版本限制，目前版本rocketmq限制在jdk15以下
