或者

Register 的地址是  dubbo://127.0.0.1:20880， 这明显不对

 

注意其后面出现：

java.net.UnknownHostException: erdp200: erdp200: 未知的名称或服务

 

erdp200 是我的主机名， 奇怪的事， 竟然识别不了 erdp200？

后面发现 ， 需要修改 /etc/hosts ， 增加对应的 ip hostname  这样的一行就好了！

 

为什么读取的不是lan 的ip，

而是虚拟网卡的ip：

addressOp = /172.18.0.1
localAddress0 = /172.18.0.1

 

因为我安装了 docker，k8s的原因吗？

但是， 同事那边也有这个问题啊， 他都已经加的了， 为什么还这样？ 哦， 原来他的hostname 是 localhost.localdomain

 

 

 

我也是醉了， 原来他的hostname没有改， 这样的话，下面的配置的 最后一行是没有用的

 

 /etc/hosts 中手动添加的 ip hostname  从而没有用，因为这里的hostname 并不是其实际的 hostname 。。 难怪呢 难怪他启动dubbo 的时候也没有报 UnknownHostException 的错误，

2019-08-14 15:02:12.784  INFO 16140 --- [           main] o.a.dubbo.registry.nacos.NacosRegistry   :  [DUBBO] Load registry cache file /root/.dubbo/dubbo-registry-erdp-discuss-app-192.168.0.143:8848.cache, data: {com.lkk.platform.system.domain.service.ELPeopleService:1.0.0=dubbo://127.0.0.1:20880/com.lkk.platform.system.domain.service.ELPeopleService?anyhost=true&application=erdp-system-app&bean.name=com.lkk.platform.system.domain.service.ELPeopleService&category=providers&default.cluster=failfast&default.connections=5&default.deprecated=false&default.dynamic=false&default.loadbalance=leastactive&default.register=true&default.retries=0&default.timeout=10000&default.version=1.0.0&deprecated=false&dubbo=2.0.2&dynamic=false&generic=false&interface=com.lkk.platform.system.domain.service.ELPeopleService&logger=slf4j&methods=batchAddOrUpdate,selectFieldListByActive,checkUserAccount,insertOrUpdate,deleteByMap,queryDimissionPage,getPeopleByOrgIds,updateBatchById,resetButton,insertAllColumn,findUser,expirationReminder,InInsert,getTableName,selectById,getResetPwdByCode,deleteById,insertBatch,selectCount,updateAllColumnById,queryPage,getCodeById,getUser,save,updateAllColumnBatchById,update,insert,delete,selectAvlbFieldList,deleteBatchIds,getUserByCode,fuzzyQueryPage,getUserByNameOrEmail,fuzzyFindUser,get,getIdByCode,updateUserPinyin,batchList,selectPage,updatePwd,getLeaderIdByOrgIds,updateById,selectBatchIds,selectList,selectOne,insertOne,getUserByName,getPeople,getUserView,queryById&path=com.lkk.platform.system.domain.service.ELPeopleService&pid=5646&protocol=dubbo®ister=true&release=2.7.1&revision=2.0.2-SNAPSHOT&side=provider&threadpool=fixed&threads=50&timeout=1200000×tamp=1565753463091}, dubbo version: 2.7.1, current host: 127.0.0.1

 

因为 localhost.localdomain 并不是 unknown， 只是解析到最后 org.apache.dubbo.common.utils.NetUtils 只能返回  127.0.0.1。

 

看过 org.apache.dubbo.common.utils.NetUtils 源码，其实他的获取ip 的逻辑还是比较复杂的。 首先是通过hostname 去获取，获取不到才是通过 遍历 网卡的方式，获取到第一个有效的 网卡ip 就返回。 我开始还以为是 linux 机器网卡、虚拟网卡太多了（安装了 docker、k8s）的原因呢！

 

但是 后面 怎么又变成了 127.0.0.1 呢？ 。。。 未完待续
