最近我正在研究超级账本/fabric-peer。

我测试了对等网络的设置。

我发现使用 docker hub 中的这些图像来设置网络，

我不能让对等方重新连接网络。

以下是我所做的。

  1. 获得四台电脑。安装 ubuntu 服务器 16.04
  2. 获取 docker 1.12.2 和 docker-compose 1.9.0-rc1 。

  3. 编写 docker-compose.yml

    版本：'2' 服务：vp1：network_mode：主机图像：hyperledger/fabric-peer:x86_64-0.6.0-preview 端口：-“7050:7050”-“7051:7051”-“7052:7052”-“7053 :7053" 卷：- ./patch:/opt/gopath/src/chaincode 环境：- CORE_PEER_ADDRESSAUTODETECT=true - CORE_VM_ENDPOINT= http://localhost:2375 - CORE_PEER_ADDRESS=192.168.1.101:7051 - CORE_PEER_DISCOVERY_ROOTNODE=192.168.1.100:7051 - CORE_LOGGING_LEVEL=info - CORE_PEER_ID=vp1 - CORE_PEER_VALIDATOR_ENABLED=true - CORE_PEER_VALIDATOR_CONSENSUS_PLUGIN=pbft 命令：对等节点启动

  4. 获取对等体的图像。

    我得到三个泊坞窗图像。

    • 超级账本/fabric-peer:x86_64-0.6.1-preview
    • 超级账本/fabric-peer:x86_64-0.6.0-preview
    • hyperledger/fabric-peer:x86_64-0.7.0-SNAPSHOT-c6e56d6 // 我通过使用 vagrant 并使 peer 不在 docker hub 中得到这个。

  5. docker-compose up，启动四个peer节点

  6. 码头工人停止 vp3

  7. 码头工人启动vp3

  8. 我收到错误，对等方重新连接错误

    在 vp3 中，[peer] FSM 错误 vp0:... 重复 vp1... vp2... 在 vp0、vp1、vp2 中，[peer] FSM 错误 vp3:... 重复

  9. 换个图，发现三张图片报错一样

所以，我的问题是，fabric-peer 现在真的完成了对等重新连接吗？

如何解决重启的peer重连？重新连接网络错误，然后网络只是与三个对等方进行 CONSENSUS 放弃第四个。

附言

使用 docker pause vp3 和 docker unpause vp3 ，

网络还可以，但这没有任何意义。

这是日志。

如果您仍在使用 Fabric Hyperledger 进行开发，那么现在有一个 1.0 版本，它是您使用的旧版本的重写。这是文档的链接https://hyperledger-fabric.readthedocs.io/en/latest/ 教程做得很好，是开始的好地方。
