异常原因：
第一种可能：虚拟机中的网络太多。
rocketMQ在自动识别网络的时候识别错误。可以先把别的网络down掉，或者把想用的那个网让它排在前面(没验证过)
ifconfig查看网络发现还有个docker0的网络，那个ip就是172.17.0.1。因此连接不上。
先把docke0的网络停了

systemctl stop docker
sudo ifconfig docker0 down

docker服务启动后docker0网络会自动开。

systemctl start docker

只是测试的时候先把其他网络关了。如果要用docker部署，启动docker就好。

第二种：setVipChannelEnabled(false)
在启动broker的时候，启动成功后会看到broker跑在一个地址上，看上面的端口号(不是10909就是10911)和报的错的端口是否能对应上。通过producer.setVipChannelEnabled(false)来调整端口，一个是10909一个是10911，具体哪个不记得了。
