RocketMQ本地集群配置
修改NameServer默认端口达到本地集群配置
conf目录下新建一个配置文件conf/namesrv.properties，文件内容为：
listenPort=2058
使用 mqnamesrv -c ../conf/namesrv.properties 指定nameserver配置文件，示例：
PS E:\111softwares\rocketmq-all-4.4.0-bin-release\bin> .\mqnamesrv -c ../conf/namesrv.properties
"set java env ok."
Java HotSpot(TM) 64-Bit Server VM warning: Using the DefNew young collector with the CMS collector is deprecated and will likely be removed in a future release
Java HotSpot(TM) 64-Bit Server VM warning: UseCMSCompactAtFullCollection is deprecated and will likely be removed in a future release.
load config properties file OK, ../conf/namesrv.properties
The Name Server boot success. serializeType=JSON
配置Broker本地集群
./mqbroker -n localhost:9876 -c ../conf/2m-2s-sync/broker-a.properties
在conf/broker-*.properties配置文件中指定nameserver：
brokerClusterName = DefaultCluster
brokerName = broker-a
brokerId = 0
deleteWhen = 04
fileReservedTime = 48
brokerRole = ASYNC_MASTER
flushDiskType = ASYNC_FLUSH
autoCreateTopicEnable=true
namesrvAddr=localhost:9876;localhost:2058
listenPort=10911
2主2从同步(2m-2s-sync)集群配置
2m-2s-sync目录下：
第一个主从节点
broker-a.properties
brokerClusterName=DefaultCluster
brokerName=broker-a
brokerId=0

在bin目录下分别执行，依次启动2主2从集群的Broker：
./mqbroker -n localhost:9876;localhost:2058 -c ../conf/2m-2s-sync/broker-a.properties
./mqbroker -n localhost:9876;localhost:2058 -c ../conf/2m-2s-sync/broker-a-s.properties
./mqbroker -n localhost:9876;localhost:2058 -c ../conf/2m-2s-sync/broker-b.properties
./mqbroker -n localhost:9876;localhost:2058 -c ../conf/2m-2s-sync/broker-b-s.properties
