RocketMQ常备知识汇总

创建文件目录：
mkdir -p /home/rocketmq/store/broker-a /home/rocketmq/store/broker-a/consumequeue /home/rocketmq/store/broker-a/commitlog /home/rocketmq/store/broker-a/index /home/rocketmq/broker-a/logs
unzip rocketmq-all-4.8.0-bin-release.zip
mv rocketmq-all-4.8.0-bin-release rocketmq-4.8.0

vim broker.conf
#Broker 对外服务的监听端口
listenPort=10911
##是否允许 Broker 自动创建Topic，建议线下开启，线上关闭
autoCreateTopicEnable=true
##是否允许 Broker 自动创建订阅组，建议线下开启，线上关闭
autoCreateSubscriptionGroup=true
##nameServer地址，分号分割
namesrvAddr=localhost:9876
##存储路径
storePathRootDir=/home/rocketmq/store/broker-a
##commitLog 存储路径
storePathCommitLog=/home/rocketmq/store/broker-a/commitlog
##消费队列存储路径存储路径
storePathConsumeQueue=/home/rocketmq/store/broker-a/consumequeue
##消息索引存储路径
storePathIndex=/home/rocketmq/store/broker-a/index
##checkpoint 文件存储路径
storeCheckpoint=/home/rocketmq/store/broker-a/checkpoint

启动：
修改bin目录下的runbroker.sh 和 runserver.sh 文件
比如把8g 4g 改成512m， 4g 2g改成256m
cd /home/rocketmq/rocketmq-4.8.0/bin
nohup sh mqnamesrv &
nohup sh mqbroker -c /home/rocketmq/rocketmq-4.8.0/conf/broker.conf &
查看日志：
tail -f ~/logs/rocketmqlogs/namesrv.log
tail -f ~/logs/rocketmqlogs/broker.log
关闭服务：
cd /home/rocketmq/rocketmq-4.8.0/bin/
sh mqshutdown namesrv
sh mqshutdown broker

cd /home/rocketmq/rocketmq-externals-master/rocketmq-console/src/main/resources
cd /home/rocketmq/rocketmq-externals-master/rocketmq-console
mvn clean package -Dmaven.test.skip=true
mvn clean package -Dcheckstyle.skip=true
cd target
nohup java -jar rocketmq-console-ng-2.0.0.jar &
