启动

nohup sh /home/rocketmq/bin/mqnamesrv & #两个Master
nohup sh /home/rocketmq/bin/mqbroker -c /home/rocketmq/conf/2m-noslave/broker-a.properties >/dev/null 2>&1 & #Master1
nohup sh /home/rocketmq/bin/mqbroker -c /home/rocketmq/conf/2m-noslave/broker-b.properties >/dev/null 2>&1 & #Master2

日志查询

 日志路径可能存在两个地方。

@ 路径一：
# /root/logs/rocketmqlogs
@ 路径二：
# /home/rocketmq/logs/rocketmqlogs

基础命令

1. 查看所有消费组group:
	sh mqadmin consumerProgress -n 10.10.11.214:9876
2. 查看指定消费组下的所有topic数据堆积情况：
	sh mqadmin consumerProgress -n 10.10.11.214:9876 -g benchmark_consumer_33
3. 查看所有topic :
	sh mqadmin topicList -n 10.10.11.214:9876
4. 查看topic信息列表详情统计
	sh mqadmin topicstatus -n 10.10.11.214:9876 -t myTopicTest1
5.  新增topic
	sh mqadmin updateTopic -n 10.10.11.214:9876 -c AdpMqCluster -t topic123
6. 删除topic
	sh mqadmin deleteTopic –n 10.10.11.214:9876 –c groupname –t topicname 
7. 批量删除topic
	for topic in $(/home/rocketmq/bin/mqadmin topicList -n 10.10.11.214:9876);do echo ${topic};/home/rocketmq/bin/mqadmin deleteTopic -n 10.10.11.214:9876 -c AdpMqCluster -t ${topic};done
8.查询集群消息
	sh mqadmin clusterList -n myc2:9876

清空topic(重置集群)

如topic创建时，topic名称中加入了空格、特殊字符的情况下，通过mqadmin delete topic可能无法删除。
如果无重要数据，可以通过删除文件方式删除topic，这种情况下，所有的数据和配置	信息都会丢失。

主要包括namesrv和broker两部分数据数据需要清理：

• 停止RocketMQ集群即可
• 删除namesrv的数据文件 (一般默认在/root/store和/root/logs下)

# rm -rf /root/logs/rocketmqlogs/*
# rm -rf /root/store/checkpoint
# rm -rf /root/store/config/*

• 删除broker的数据文件 (一般在rocketmq安装目录下的store目录)

# rm -rf /home/jetflow/rocketmq/logs/rocketmqlogs/*
# rm -rf /home/jetflow/rocketmq/data/store/*
# mkdir -p /home/jetflow/rocketmq/data/store/{commitlog,consumequeue,index,checkpoint,abort}

• 启动RocketMQ集群即可
