RocketMQ中broker配置brokcerIP1和brokerIP2的作用

brokerIP1 当前broker监听的IP
brokerIP2 存在broker主从时，在broker主节点上配置了brokerIP2的话,broker从节点会连接主节点配置的brokerIP2来同步。

默认不配置brokerIP1和brokerIP2时，都会根据当前网卡选择一个IP使用，当你的机器有多块网卡时，很有可能会有问题。比如，我遇到的问题是我机器上有两个IP，一个公网IP，一个私网IP，结果默认选择的走公网IP，这是不正确的，我期望的是所有业务内部通信都走内网。

举个例子，在下面部署架构的情况下的各broker节点配置文件：

两个namesrv，两主两从，异步
10.10.10.1 namesrv1
10.10.10.2 namesrv2
10.10.10.3 broker-a
10.10.10.4 broker-b
10.10.10.5 broker-a-s
10.10.10.6 broker-b-s

broker-a的配置

brokerClusterName=DefaultCluster
brokerIP1=10.10.10.3
brokerIP2=10.10.10.3
brokerName=broker-a
brokerId=0
deleteWhen=04
fileReservedTime=48
brokerRole=ASYNC_MASTER
flushDiskType=ASYNC_FLUSH
#nameServer地址，分号分割
namesrvAddr=10.10.10.1:9876;10.10.10.2:9876
#存储路径
storePathRootDir=/home/rocketmq/rocketmq/data
#commitLog 存储路径

broker-b的配置

brokerClusterName=DefaultCluster
