serverChannelMaxIdleTimeSeconds = 120
listenPort = 9876
serverCallbackExecutorThreads = 0
serverAsyncSemaphoreValue = 64
serverSocketSndBufSize = 4096
rocketmqHome = /home/baseuser/rocketmq
clusterTest = false
serverSelectorThreads = 3
useEpollNativeSelector = false
orderMessageEnable = false
serverPooledByteBufAllocatorEnable = true
kvConfigPath = /home/baseuser/namesrv/kvConfig.json
serverWorkerThreads = 8
serverSocketRcvBufSize = 4096
productEnvName = center
serverOnewaySemaphoreValue = 256
configStorePath = /home/baseuser/namesrv/namesrv.properties
2.删除nameSrv配置
sh bin/mqadmin deleteKvConfig -n 192.168.1.x:9876 -s namesapce -k key

update KV config.
-s set the namespace
-k key set the key name
-v value set the key value
4.更新nameSrv配置
sh bin/mqadmin updateNamesrvConfig -n 192.168.1.x:9876 -s namesapce -k key
update KV config.
