@SchopenhauerZhang 1主2从（DLedger 模式）你只需要按照controller+一主一从的模式（2个broker）部署3个Broker就可以了。 通过Controller模式的选举出来1主剩下的2个Broker就是Slave. 这个就满足你的controller+1主2从。官方文档：https://rocketmq.apache.org/docs/deploymentOperations/03autofailover 这里只是一个例子。例如你想要1主2从： Broker1 ```properties brokerClusterName = DefaultCluster brokerName = broker-a brokerId = -1 brokerRole = SLAVE deleteWhen = 04 fileReservedTime = 48 enableControllerMode = true controllerAddr = 127.0.0.1:9878 namesrvAddr = 127.0.0.1:9876 allAckInSyncStateSet=true listenPort=30911 storePathRootDir=/tmp/rmqstore/node00 storePathCommitLog=/tmp/rmqstore/node00/commitlog ``` Broker2 ```properties brokerClusterName = DefaultCluster brokerName = broker-a brokerId = -1 brokerRole = SLAVE deleteWhen = 04 fileReservedTime = 48 enableControllerMode = true controllerAddr = 127.0.0.1:9878 namesrvAddr = 127.0.0.1:9876 allAckInSyncStateSet=true listenPort=30911 storePathRootDir=/tmp/rmqstore/node00 storePathCommitLog=/tmp/rmqstore/node00/commitlog ``` Broker3 ```properties brokerClusterName = DefaultCluster brokerName = broker-a brokerId = -1 brokerRole = SLAVE deleteWhen = 04 fileReservedTime = 48 enableControllerMode = true controllerAddr = 127.0.0.1:9878 namesrvAddr = 127.0.0.1:9876 allAckInSyncStateSet=true listenPort=30911 storePathRootDir=/tmp/rmqstore/node00 storePathCommitLog=/tmp/rmqstore/node00/commitlog ``` 只需要按照上述的配置文件部署就可以了。 （这里因为storePathRootDir和storePathCommitLog都是一样所以需要部署在不同的机器上面，如果想要部署在同一台机器只需要进行改变位置即可） GitHub link: https://github.com/apache/rocketmq/discussions/6172#discussioncomment-5113859 ---- This is an automatically sent email for dev@rocketmq.apache.org.
