我正在尝试设置Hyperledger Fabric v1.0，其中3个orderers连接到多个主机环境下的4个kafka节点，但我在orderer控制台发现错误＆＃34; broker.go:96：无法连接到代理e13a106f3821：9092 ：拨tcp：i / o timeout＆＃34; 。贝娄是我的环境：
1.一个主机运行org1,1个orderer，4个kafka节点和3个zookeeper的对等体
2.一个主机运行org2,1 orrrer的同行
org1似乎正好相邻我在org2的orderer的控制台日志中看到了下面的错误

看来orderer无法连接到kafka0或其他人。
有人请帮忙吗？

无法连接到代理商b5a700af19de：9092：拨打tcp：lookup b5a700af19de在127.0.0.11:53：没有这样的主机
似乎DNS配置错误。你应该检查你的configtx.yaml或/ etc / hosts文件。

确保正确执行以下操作。
