1. Stop rocketmq: kill -9 just kill it all

2. Delete logs/rocketmqlogs : a large number of logs under/root

3. Delete/root/store : topic and other information in MQ that seems to be accumulated

4. [optional] Clear topics displayed in MQ

sh mqadmin topicList -n 192.168.1.4:9876

sh mqadmin deleteTopic -c HOSTNAME -n 192.168.1.4:9876 -t orderTopic

*. Then restart rocketmq and try step four to see if it's clean

p.s.

1. It is critical to stop rocketmq and clear the order first; if it is not clear, rocketmq does not know where to reload all accumulated, resulting in failure to start rocketmq.

2. deleteTopic is not required, but when deleting it, you generally need to specify-c, you can try using hostname
