实例化链码，sendPeersProposal - Promise被拒绝：错误：REQUEST_TIMEOUT，Hyperledger Fabric，linux

我在linux os上从结构节点sdk实例化特定对等体上的链代码时，会从对等端获得超时错误 .

error: [Peer.js]: sendProposal - timed out after:90000
error: [client-utils.js]: sendPeersProposal - Promise is rejected: Error: REQUEST_TIMEOUT

我能够创建 Channels ，加入 Channels ，使用现有设置安装链码 . 成功实例化对等链码的缺失是什么？

我的码头工具组成设置：

peer0.org1.example.com:
    container_name: peer0.org1.example.com
    extends:
      file:   base.yaml
      service: peer-base
    environment:
      - CORE_PEER_ID=peer0.org1.example.com
      - CORE_PEER_LOCALMSPID=Org1MSP
      - CORE_PEER_ADDRESS=peer0.org1.example.com:7051
    ports:
      - 7051:7051
      - 7053:7053
    volumes:
        - ./channel/crypto-config/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/:/etc/hyperledger/crypto/peer
    depends_on:
      - orderer.example.com

            }
        }

什么是网络设置专用的绑定？任何可能的根本原因？

    你对这个过程是正确的 . 如果所有操作都很好，那么我认为docker文件很好 . 但您必须确保，您只能从安装了链代码的对等方实例化链代码 . 因为链代码安装不会改变通道配置 .

    经过一些研究后我得到了答案 .

    1）我的码头版本是1.7 . 并且它不再受Fabric节点sdk的支持 . 我必须更新我的docker版本 . 我的Cent OS版本是7.0，它的支持docker高达17.6 .

    2）实例化响应大约需要2分钟的往返时间 . 用于在节点sdk中实例化链代码的默认超时为45秒 . 将其更改为3分钟后，我可以成功运行整个应用程序 .
