问题

在本地启动dubbo时，服务注册在本地的zookeeper ，但是注册IP却不是本地的iP。产生问题，导致consumer 找不到provider ，访问不了服务。

  • 例如 本地IP为 10.0.0.1 ，但是zookeeper上的注册ip 可能是 196.168.0.1

产生原因，随机产生，可能是你重启一下机器，或者电脑小智一段时间就会发生。

  • 报错类似

解决方法

在程序配置文件中 配置dubbo 的注册中心“dubbo.registry.address” 时要注意不要配置127.0.0.1 要配置为 localhost。

然后在配置本地的/etc/hosts 文件中

127.0.0.1 localhost

问题原因

怀疑原因：为本地配置127.0.0.1 时由于连着网络所以dns 解析解析到了你的网络上了。么有解析到本机造成的。但是并不确定是不是这个原因。
