問題
在本地啟動dubbo時，服務注冊在本地的zookeeper ，但是注冊IP卻不是本地的iP。產生問題，導致consumer 找不到provider ，訪問不了服務。
- 例如 本地IP為 10.0.0.1 ，但是zookeeper上的注冊ip 可能是 196.168.0.1
產生原因，隨機產生，可能是你重啟一下機器，或者電腦小智一段時間就會發生。

解決方法
在程序配置文件中 配置dubbo 的注冊中心“dubbo.registry.address” 時要注意不要配置127.0.0.1 要配置為 localhost。
然后在配置本地的/etc/hosts 文件中
127.0.0.1 localhost
問題原因
懷疑原因：為本地配置127.0.0.1 時由于連著網絡所以dns 解析解析到了你的網絡上了。么有解析到本機造成的。但是并不確定是不是這個原因。
