错误信息如下：

Could not get local host ip address, will use 127.0.0.1 instead., dubbo version: 2.0.1, current hos

解决方案一：

绑定hostname+ip
先执行 ：

vi /etc/hostname
假定hostname 为： zzf

获取hostname , 在hosts 中绑定

vim /etc/hosts
添加如下 ：
10.2.3.4 zzf

解决方案2：(不建议使用)

在dubbo的配置文件中写死host

在协议上绑定
<dubbo:protocol host="172.16.11.111"/>

或者在每个provider中绑定host
<dubbo:provider host="172.16.11.111">
