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(peer0和peer1)
其中：

主机A上运行orderer、ca、peer0，couchDB、cli
主机B上运行peer1、couchDB、cli

1.2 前期准备

为主机添加hosts映射

主机A(Peer0)
修改/etc/hosts，添加orderer和peer1节点的映射

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

主机B(Peer1)
修改/etc/hosts，添加orderer和peer0节点的映射

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

修改org中的Peer数

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

运行脚本生成配置文件

# ./generate.sh

运行后会生成两个文件夹config、crypto-config

将config、crypto-config复制到主机A、B
(注意：这里可能会出现复制权限的问题，可以通过nautilus进行复制)

2.2 docker-compose.yml

主机A（peer0）

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
...

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
    ...

cli中添加对peer0节点的依赖

cli:
    ...
    depends_on:
    #  - orderer.example.com
      - peer0.org1.example.com
    #  - couchdb
    ...

主机B（peer1）
复制原始的docker-compose.yml文件，粘贴为docker-compose2.yml去除orderer和ca服务配置，并对peer和cli做修改

peer
修改节点名称为peer0为peer1
volumes里添加hosts映射
依赖中去除orderer

2.3 修改脚本

主机A（peer0）
修改start.sh脚本，添加从容器中将信道文件导出到/tmp/目录下

#!/bin/bash
#
# Copyright IBM Corp All Rights Reserved
#
# SPDX-License-Identifier: Apache-2.0
#
# Exit on first error, print all commands.
set -ev

# don't rewrite paths for Windows Git Bash users
export MSYS_NO_PATHCONV=1

docker-compose -f docker-compose.yml down

docker-compose -f docker-compose.yml up -d ca.example.com orderer.example.com peer0.org1.example.com couchdb

# wait for Hyperledger Fabric to start
# incase of errors when running later commands, issue export FABRIC_START_TIMEOUT=<larger number>
export FABRIC_START_TIMEOUT=10
#echo ${FABRIC_START_TIMEOUT}
sleep ${FABRIC_START_TIMEOUT}

# Create the channel
docker exec -e "CORE_PEER_LOCALMSPID=Org1MSP" -e "CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/msp/users/Admin@org1.example.com/msp" peer0.org1.example.com peer channel create -o orderer.example.com:7050 -c mychannel -f /etc/hyperledger/configtx/channel.tx

#复制信道文件
docker cp peer0.org1.example.com:/opt/gopath/src/github.com/hyperledger/fabric/mychannel.block /tmp/

# Join peer0.org1.example.com to the channel.
docker exec -e "CORE_PEER_LOCALMSPID=Org1MSP" -e "CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/msp/users/Admin@org1.example.com/msp" peer0.org1.example.com peer channel join -b mychannel.block

主机B（peer1）
复制原始的start.sh文件，粘贴为start2.sh文件，清空内容并写入如下：

set -ev

export MSYS_NO_PATHCONV=1

docker-compose -f docker-compose2.yml down

docker-compose -f docker-compose2.yml up -d peer1.org1.example.com couchdb

# wait for Hyperledger Fabric to start
# incase of errors when running later commands, issue export FABRIC_START_TIMEOUT=<larger number>
export FABRIC_START_TIMEOUT=10
#echo ${FABRIC_START_TIMEOUT}
sleep ${FABRIC_START_TIMEOUT}

#复制信道文件
docker cp /tmp/mychannel.block peer1.org1.example.com:/opt/gopath/src/github.com/hyperledger/fabric/

# Join peer0.org1.example.com to the channel.
docker exec -e "CORE_PEER_LOCALMSPID=Org1MSP" -e "CORE_PEER_MSPCONFIGPATH=/etc/hyperledger/msp/users/Admin@org1.example.com/msp" peer1.org1.example.com peer channel join -b mychannel.block

3. 启动网络

3.1 主机A（peer0）

在fabcar目录下，新建startp3.sh脚本,写入

#!/bin/bash
#
# 没有链码实例化，用于多机分布运行
# Exit on first error
set -e

# don't rewrite paths for Windows Git Bash users
export MSYS_NO_PATHCONV=1
starttime=$(date +%s)
LANGUAGE=${1:-"golang"}
CC_SRC_PATH=github.com/fabcar/go
if [ "$LANGUAGE" = "node" -o "$LANGUAGE" = "NODE" ]; then
    CC_SRC_PATH=/opt/gopath/src/github.com/fabcar/node
fi

# clean the keystore
# rm -rf ./hfc-key-store

# launch network; copy channel and join peer to channel
cd ../basic-network
./start.sh

# Now launch the CLI container in order to install, instantiate chaincode
docker-compose -f ./docker-compose.yml up -d cli

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 install -n fabcar -v 1.0 -p "$CC_SRC_PATH" -l "$LANGUAGE"

#sleep 10
printf "\nTotal setup execution time : $(($(date +%s) - starttime)) secs ...\n\n\n"

执行脚本

./startp3.sh

3.3 实例化链玛容器

注：链玛只需实例化一次，这里

在主机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

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

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

peer节点配置添加了关于hosts映射
cli对peer节点配置依赖的方法

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...
