> 在broker配置了listenPort=30911，启动后发现30909和30912都被rocketmq占用了，这是正常的吗？

30909 被占用是因为启动了 fastRemotingServer

https://github.com/apache/rocketmq/blob/88000dac212a0c721a99ca167132920ce0f45f1b/broker/src/main/java/org/apache/rocketmq/broker/BrokerController.java#L429-L435

30912 被占用是供 HA 使用

https://github.com/apache/rocketmq/blob/88000dac212a0c721a99ca167132920ce0f45f1b/container/src/main/java/org/apache/rocketmq/container/BrokerContainerStartup.java#L140

> 另外想问下mqshutdown broker能指定broker吗？

不能，mqshutdown 是通过 `ps` 来获取 broker pid 的
