異常原因：
第一種可能：虛擬機中的網絡太多。
rocketMQ在自動識別網絡的時候識別錯誤。可以先把別的網絡down掉，或者把想用的那個網讓它排在前面(沒驗證過)
ifconfig查看網絡發現還有個docker0的網絡，那個ip就是172.17.0.1。因此連接不上。
先把docke0的網絡停了

systemctl stop docker
sudo ifconfig docker0 down

docker服務啟動后docker0網絡會自動開。

systemctl start docker

只是測試的時候先把其他網絡關了。如果要用docker部署，啟動docker就好。

 

第二種：setVipChannelEnabled(false)
在啟動broker的時候，啟動成功后會看到broker跑在一個地址上，看上面的端口號(不是10909就是10911)和報的錯的端口是否能對應上。通過producer.setVipChannelEnabled(false)來調整端口，一個是10909一個是10911，具體哪個不記得了。
