软硬件环境
硬件：阿里云主机4c16G1T
操作系统：centos7.6
1. 安装运行依赖
1.1. git
yum install -y git
1.2. docker
yum install -y docker
system enable docker
systemctl start docker
1.3. docker-compose
yum install -y docker-compose
1.4. golang
下载并解压
wget https://dl.google.com/go/go1.13.linux-amd64.tar.gz
tar -C /usr/local -xzf go1.13.linux-amd64.tar.gz
设置path
vi 〜/ .bash_profile
将以下内容追加到bash_profile
export GOROOT=/usr/local/go
export GOPATH=/root/gopath
export PATH=$PATH:$GOROOT/bin:$GOPATH/bin
保存文件，执行以下命令
source ~/.bash_profile
创建gopath目录，go get相关的库将下载到这里
mkdir -p /root/gopath
测试是否成功
go env
2. 拉取fabric源码
创建一个目录并进入
$ mkdir -p ~/go/src/github.com/hyperledger
$ cd ~/go/src/github.com/hyperledger
拉取代码，并切换到指定分支
$ git clone https://github.com/hyperledger/fabric.git
$ cd fabric
$ git branch -a
$ git checkout v1.4.4
3. 拉取依赖(命令、镜像、fabric-samples库)
对网络有要求，镜像慢可以配置镜像加速
cd ~/go/src/github.com/hyperledger/fabric/scripts
$./bootstrap.sh -h
Usage: bootstrap.sh [version [ca_version [thirdparty_version]]] [options]
options:
-h : this help
-d : bypass docker image download
-s : bypass fabric-samples repo clone
-b : bypass download of platform-specific binaries
ca1.4.4仓库没有，无法下载，因而配置1.4.3

./bootstrap.sh 1.4.4 1.4.3 0.4.18
- 如果当前目录没有 hyperledger/fabric-samples，会从 github.com 克隆 hyperledger/fabric-samples 存储库； 使用 checkout 签出对应指定的版本标签；
- 将指定版本的 Hyperledger Fabric 平台特定的二进制文件和配置文件安装到 fabric-samples - 存储库的根目录中；
- 下载指定版本的 Hyperledger Fabric Docker 镜像文件;将下载的 Docker 镜像文件标记为 “lastest"。
查看二进制脚本,将看到8个fabric二进制命令
$ls ~/go/src/github.com/hyperledger/fabric/scripts/fabric-samples/bin/
configtxgen configtxlator cryptogen discover fabric-ca-client idemixgen orderer peer
移动位置
mv fabric-samples/ ~/go/src/github.com/hyperledger/
设置path
vi 〜/ .bash_profile
修改最后一行
export PATH=$PATH:$GOROOT/bin:$GOPATH/bin:~/go/src/github.com/hyperledger/fabric-samples/bin
保存文件，执行以下命令
source ~/.bash_profile
4. 启动first-network
cd ~/go/src/github.com/hyperledger/fabric-samples/first-network/
byfn.sh generate -c mychannel
./byfn.sh up -c mychannel -i 1.4.4
5.first-network步骤解读
5.1. 创建配置文件
configtxgen -profile TwoOrgsOrdererGenesis -channelID byfn-sys-channel -outputBlock ./channel-artifacts/genesis.block
configtxgen -profile TwoOrgsChannel -outputCreateChannelTx ./channel-artifacts/channel.tx -channelID mychannel
configtxgen -profile TwoOrgsChannel -outputAnchorPeersUpdate ./channel-artifacts/Org1MSPanchors.tx -channelID mychannel -asOrg Org1MSP
configtxgen -profile TwoOrgsChannel -outputAnchorPeersUpdate ./channel-artifacts/Org2MSPanchors.tx -channelID mychannel -asOrg Org2MSP
5.2. 创建通道
admin.org1 连接 peer0.org1 节点，向 orderer 节点传递要创建的通道名称 CHANNEL_NAME （默认为 mychannel）和通道配置交易 channel.tx。如果创建成功，则返回通道的创世区块 CHANNEL_NANE.block，该区块包含 channel.tx 指定的通道配置信息，保存在 CLI 容器中
peer channel create -o orderer.example.com:7050 -c $CHANNEL_NAME -f ./channel-artifacts/channel.tx --tls $CORE_PEER_TLS_ENABLED --cafile $ORDERER_CA >&log.txt
5.3.加入通道
先加入通道 再遍历org 再遍历peer
peer channel join -b $CHANNEL_NAME.block >&log.txt
5.4.更新锚节点
peer channel update -o orderer.example.com:7050 -c mychannel -f ./channel-artifacts/Org1MSPanchors.tx --tls true --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem
peer channel update -o orderer.example.com:7050 -c mychannel -f ./channel-artifacts/Org2MSPanchors.tx --tls true --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem
5.5.安装链码
peer chaincode install -n mycc -v 1.0 -l golang -p github.com/chaincode/chaincode_example02/go/
5.6.实例化链码
peer chaincode instantiate -o orderer.example.com:7050 --tls true --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C mychannel -n mycc -l golang -v 1.0 -c '{"Args":["init","a","100","b","200"]}' -P 'AND ('\''Org1MSP.peer'\'','\''Org2MSP.peer'\'')'
5.7.查询
peer chaincode query -C mychannel -n mycc -c '{"Args":["query","a"]}'
5.8.调用链码
peer chaincode invoke -o orderer.example.com:7050 --tls true --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C mychannel -n mycc --peerAddresses peer0.org1.example.com:7051 --tlsRootCertFiles /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt --peerAddresses peer0.org2.example.com:9051 --tlsRootCertFiles /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt -c '{"Args":["invoke","a","b","10"]}'
重新安装
docker volume prune
