解决阿里云部署dubbo+zookeeper和生产者时使用内网IP的问题

问题复现

zookeeper放置在阿里云服务器A，生产者放置在阿里云服务器B，消费者放置在本地的idea里面，启动消费者时出现问题：找不到生产者

具体内容为：

com.alibaba.dubbo.remoting.RemotingException: client(url: dubbo://172.17.244.206:20886/com.books.service.VipService?anyhost=true&application=springboot-dubbo-anno-consumer&check=false&codec=dubbo&default.retries=0&default.timeout=5000&dubbo=2.6.2&generic=false&heartbeat=60000&interface=com.books.service.VipService&methods=selectAllVip,selectAllVipManage,selectAllVipManageByScreen,updateUser_status,selectAllVipManageCount,selectUserXinxi,deleteVipLevel,addVipLevel,selectVipLevelByVip_no,selectVipUserIntegralByScreen,editVipLevel,selectVipUserIntegral,selectAllVipManageByScreenCount,selectVipUserIntegralByScreenCount,selectVipUserIntegralCount,editIntegralByUser_no,viewIntegralByUser_no&pid=10772&qos.accept.foreign.ip=false&qos.enable=true&qos.port=33333&register.ip=172.16.6.11&remote.timestamp=1594469993720&revision=1.0.0&side=consumer&timestamp=1594613447230) failed to connect to server /172.17.244.206:20886 client-side timeout 3000ms (elapsed: 3001ms) from netty client 172.16.6.11 using dubbo version 2.6.2

分析原因

发现关键一句：failed to connect to server /172.17.244.206:20886
说明连接不到生产者，这里看到在注册中心的生产者IP明显是一个阿里云的内网地址

所以才会导致在本地无法连接到生产者。

解决办法

将阿里云的本机IP改为对应的公网IP即可
1.先查看本机hostname

2.修改hosts


修改后立即生效
3.重启生产者和消费者
4.查看注册中心，已经改为公网ip，问题解决
