尝试在多主机环境中通过kafka群集设置Hyperledger Fabric v1.0订单器

Question

我正在尝试设置Hyperledger Fabric v1.0，其中3个订单者连接到多主机环境中的4个kafka节点，但我在订单者控制台发现错误"broker.go:96:无法连接到代理e13a106f3821:9092:拨号tcp: i/o超时“。Bellow是我的环境：

1. 一个主机运行org1的对等体，1个排序器，4个kafka节点和3个zookeeper
2. 一个主机运行org2的对等体，1个排序器

org1似乎正常运行，但我在org2的订单者控制台日志中看到以下错误

订购者似乎无法连接到kafka0或其他网站。

有人能帮帮忙吗？

Answer 1

无法连接到代理b5a700af19de:9092: dial : lookup b5a700af19de on 127.0.0.11:53:没有这样的主机

这似乎是DNS配置错误。您应该检查configtx.yaml或/etc/hosts文件。

Answer 2

确保你已经正确地做了以下事情。

Docker-Swarm

• Created

• Configured Docker-Swarm

• Created

• In yaml您必须使用主机名而不是IP地址。

• 在运行zookeeper和kafka容器时，请确保环境变量正确。

• -e "ZOO_SERVERS=server.1=zookeeper0:2888:3888 server.2=zookeeper1:2888:3888 zookeeper KAFKA_ZOOKEEPER_CONNECT=zookeeper0:2181，zookeeper 1:2181，zookeeper1:2181，zookeeper
