配置說明
使用倆臺機子赊时，部署同步刷新集群钧忽，slaver和master錯開部署誉己，可以防止一臺服務(wù)器宕機后囤锉，集群依然可用
| ip | broker |
|---|---|
| 192.168.20.202 | broker-a |
| 192.168.20.202 | broker-b-s |
| 192.168.20.203 | broker-b |
| 192.168.20.203 | broker-a-s |
修改內(nèi)存
修改bin目錄下runserver.sh和runbroker.sh的內(nèi)存大小，網(wǎng)上有榔昔，就不做說明了
配置文件
在conf/2m-2s-sync文件夾中配置
在192.168.20.202中配置broker-a和broker-b-s
在192.168.20.203中配置broker-b和broker-a-s

啟動
1、啟動nameserver
分別在倆臺服務(wù)器上的rocket目錄下執(zhí)行下列命令
nohup sh bin/mqnamesrv &
通過jps命令查看到NamesrvStartup即啟動成功末盔，啟動成功會占用9876端口
2筑舅、啟動broker
1、192.168.20.202啟動主服務(wù)（broker-a）
nohup sh bin/mqbroker -c conf/2m-2s-sync/broker-a.properties &
2陨舱、192.168.20.203啟動主服務(wù)（broker-b）
nohup sh bin/mqbroker -c conf/2m-2s-sync/broker-b.properties &
3翠拣、192.168.20.202啟動從服務(wù)（broker-b-s）
nohup sh bin/mqbroker -c conf/2m-2s-sync/broker-b-s.properties &
4、192.168.20.203動從服務(wù)（broker-a-s）
nohup sh bin/mqbroker -c conf/2m-2s-sync/broker-a-s.properties &
通過jps命令查看到BrokerStartup即啟動成功
配置注意事項（一個服務(wù)器啟動多個broker才會出現(xiàn)問題）
1游盲、啟動主服務(wù)沒有問題误墓，啟動從服務(wù)器報rocketmq已存在錯誤
這種就是文件路徑一致導(dǎo)致的，只需要在配置文件中將以下配置文件路徑設(shè)置成不一樣即可
storePathRootDir=/root/rocket/store-a-s
storePathCommitLog=/root/rocket/store-a-s/commitlog
storePathConsumeQueue=/root/rocket/store-a-s/consumequeue
storePathIndex=/root/rocket/store-a-s/index
storeCheckPoint=/root/rocket/store-a-s/checkpoint
abortFile=/root/rocket/store-a-s/abort
2益缎、啟動從服務(wù)器報端口占用問題
將listenPort配置盡量拉開优烧，我發(fā)現(xiàn)配置listenPort后會服務(wù)會在占用listenPort端口后，自動占用另倆個端口链峭，一個是listenPort+1畦娄，一個是listenPort-2。（具體作用參考：https://blog.csdn.net/yucaifu1989/article/details/127983899）
舉一個列子弊仪，broker-a的listenPort配置10911熙卡，broker-b-s的listenPort配置10912，broker-a占用三個端口為10909励饵、10911驳癌、10912，broker-b-s占用三個端口為10910役听、10912颓鲜、10913表窘，那么倆個服務(wù)都會爭10912，就會報端口占用甜滨，服務(wù)啟動不了乐严。
所以我上面配置的時候listenPort一個配置10911，一個配置了10918衣摩，所以端口占用如下
