ubuntu18.04 Fabric1.1 双主机、双Peer节

2018-08-04  本文已影响42人  四丢皮得

0. IP与机器配比说明

主机A 主机B
节点 Peer0 Peer1
主机名 001 002
IP 192.168.1.149 192.168.1.189
启动节点 ca、orderer、peer0、couchdb、cli peer1、couchdb、cli

1. 说明与前期准备

1.1 说明

主要实现的功能是构建一个Fabric网络,其特点为,一个Orderer,一个Org(peer0peer1)
其中:

1.2 前期准备

为主机添加hosts映射

192.168.1.149   orderer.example.com
192.168.1.189   peer1.org1.example.com
192.168.1.149   orderer.example.com
192.168.1.149   peer0.org1.example.com

2. 修改配置

配置文件都在basic-network文件夹下

2.1 crypto-config.yaml

Template:
      Count: 3  # 原来是1,需要添加几个Peer就改称几
      # Start: 5
      # Hostname: {{.Prefix}}{{.Index}} # default
# ./generate.sh

运行后会生成两个文件夹config、crypto-config

2.2 docker-compose.yml

  1. ca服务配置中,FABRIC_CA_SERVER_CA_KEYFILE变量中,xxx_sk文件名要和新生成的/opt/gopath/src/github.com/hyperledger/fabric-samples/basic-network/crypto-config/peerOrganizations/org1.example.com/ca/9554549f657a3f46fc1a3cb4c0c28315499023e9c1bf9709418cbb28f3e26c49_sk下的文件链接一致,否则CA容器会启动失败
...
  ca.example.com:
    image: hyperledger/fabric-ca
    environment:
      - FABRIC_CA_HOME=/etc/hyperledger/fabric-ca-server
      - FABRIC_CA_SERVER_CA_NAME=ca.example.com
      - FABRIC_CA_SERVER_CA_CERTFILE=/etc/hyperledger/fabric-ca-server-config/ca.org1.example.com-cert.pem
      - FABRIC_CA_SERVER_CA_KEYFILE=/etc/hyperledger/fabric-ca-server-config/9554549f657a3f46fc1a3cb4c0c28315499023e9c1bf9709418cbb28f3e26c49_sk
...
  1. peer服务配置中,需要添加hosts文件映射
peer0.org1.example.com:
    ...
    volumes:
        - /var/run/:/host/var/run/
        - ./crypto-config/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/msp:/etc/hyperledger/msp/peer
        - ./crypto-config/peerOrganizations/org1.example.com/users:/etc/hyperledger/msp/users
        - ./config:/etc/hyperledger/configtx
        - /etc/hosts:/etc/hosts      # 添加内容在这里
    depends_on:
    #  - orderer.example.com   # 注释掉orderer节点依赖
      - couchdb
    networks:
      - basic
    ...
  1. cli中添加对peer0节点的依赖
cli:
    ...
    depends_on:
    #  - orderer.example.com
      - peer0.org1.example.com
    #  - couchdb
    ...
  1. peer
    修改节点名称为peer0为peer1
    volumes里添加hosts映射
    依赖中去除orderer

    container_name: peer1.org1.example.com

3.3 实例化链玛容器

注: 链玛只需实例化一次,这里

  1. 主机A(peer0) 上进行实例化
docker exec -e "CORE_PEER_LOCALMSPID=Org1MSP" -e "CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/users/Admin@org1.example.com/msp" cli peer chaincode instantiate -o orderer.example.com:7050 -C mychannel -n fabcar -l "golang" -v 1.0 -c '{"Args":[""]}' -P "OR ('Org1MSP.member','Org2MSP.member')"

输出信息:

发现未出现链玛容器,不过不必担心,后面使用peer1进行交互时会自动构造链玛容器

4. 测试

4.1 测试思路

在主机B(peer1)上执行invoke操作,主机A(peer0)上查询结果

4.2 测试步骤

  1. 在peer1上执行invoke put A 9
docker exec -e "CORE_PEER_LOCALMSPID=Org1MSP" -e "CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/users/Admin@org1.example.com/msp" cli peer chaincode invoke -o orderer.example.com:7050 -C mychannel -n fabcar -c '{"function":"put","Args":["A","9"]}'

结果

看到Chaincode invoke successful. result: status:200,无错误。
此时再次查看peer1上的容器docker ps -a

  1. 在peer0上执行query A

看到了刚刚在peer1上的invoke put A 9
验证成功!

5. 总结

起初在进行实验,遇到的问题是,单peer可以正常工作(执行了实例化的peer节点),但是另一个节点无法自动构造和使用链玛函数,提示:

Error: endorsement failure during query. response: status:500 message:"make sure the chaincode fabcar has been successfully instantiated and try again: getccdata mychannel/fabcar responded with error: could not find chaincode with name 'fabcar'"

翻查资料,最后看到某Fabric集群网络搭建中,服务中

此时猜测是否是在网络启动时,脚本逻辑无问题,但是由于没有将peer主机与IP进行映射,使得在peer加入信道以及信道检测peer加入的过程中,无法正常执行。

随后按照思路,实验成功,但其中原理还有待挖掘...
