前提條件
1、安裝 curl
2、安裝 docker 和 docker compose
版本查看
$ docker --version
$ docker-compose --version
3、安裝go
設置環境變量如下
$ vim ~/.bashrc
export GOPATH=/home/lqs/go
export PATH=$PATH:$GOPATH/bin
4、安裝Python
Fabric Node.js SDK需要使用 Python 2.7版本才能成功完成 npm install 操作，使用以下命令安裝
$ sudo apt-get install python
$ python --version
安裝示例、二進制文件和 Docker 鏡像
1、克隆 hyperledger/fabric-samples 倉庫
進入網址克隆 hyperledger/fabric-samples 倉庫
$ git clone https://github.com/hyperledger/fabric-samples
2、進入fabric-samples目錄執行以下命令
$ cd fabric-samples
# Fetch bootstrap.sh from fabric repository using
$ curl -sS https://raw.githubusercontent.com/hyperledger/fabric/master/scripts/bootstrap.sh -o ./scripts/bootstrap.sh
# Change file mode to executable
$ chmod +x ./scripts/bootstrap.sh
# Download binaries and docker images
//可只執行前半部分，不指定版本，系統會自動下載最新版本（該命令會下載很多鏡像，耗時較長）
$ ./scripts/bootstrap.sh [version] [ca version] [thirdparty_version]
$ ./scripts/bootstrap.sh 1.4.1 1.4.1 0.4.18
下載好之後再 fabric-samples 目錄下會生成新的文件夾 bin 和 config
文件實例如下
$ tree bin/
bin
├── configtxgen
├── configtxlator
├── cryptogen
├── discover
├── fabric-ca-client
├── idemixgen
├── orderer
└── peer
$ tree config
config/
├── configtx.yaml
├── core.yaml
└── orderer.yaml
3、環境變量配置
添加 bin 文件的路徑到PATH裏面
$ vim ~/.bashrc
export PATH=/home/lqs/fabric-samples/bin:$PATH
搭建網絡
$ cd first-network
初始化網絡
$ ./byfn.sh generate
Generating certs and genesis block for channel 'mychannel' with CLI timeout of '10' seconds and CLI delay of '3' seconds

運行示例代碼
現在再次啓動網絡運行 ./byfn.sh ，然後進入容器執行示例代碼
進入容器
$ docker exec -it cli bash
查詢 a 值
// 因爲在初始化時已經執行過一次，現在的 a 值查詢結果爲90
$ peer chaincode query -C mychannel -n mycc -c '{"Args":["query","a"]}'
執行轉賬功能（ a 轉 10 到 b）
// 該代碼爲將a的10轉給b ，執行一次之後再查詢a可看到還剩80
$ 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"]}'
退出容器並關閉網絡
$ exit
$ ./byfn.sh down
可能會出現的問題
1、docker ps 錯誤
當執行 $ docker ps 時出現以下錯誤，這是由於docker守護進程啓動的時候，會默認賦予名字爲docker的用戶組讀寫unix socket的權限， 因此只要創建docker用戶組，並將當前用戶加入到docker用戶組中，那麼當前用戶就有權限訪問unix socket了，進而就可以執行docker相關命令
Got permission denied while trying to connect to the Docker daemon socket at unix:///var/run/docker.sock: Get http://%2Fvar%2Frun%2Fdocker.sock/v1.39/containers/json: dial unix /var/run/docker.sock: connect: permission denied
採用以下命令解決
$ sudo groupadd docker # 添加用戶組
$ sudo gpasswd -a $USER docker # 將登錄用戶加入到docker用戶組中
$ newgrp docker # 更新用戶組
$ docker ps # 測試docker命令是否可用
2、docker 鏡像未關閉錯誤
當啓動網絡時出現以下錯誤，是因爲沒有 down 掉或未完全關閉，關閉 docker 進程即可
ERROR: for orderer.example.com Cannot create container for service orderer.example.com: Conflict. The container name "/orderer.example.com" is already in use by container "568211c4b119eaebc27c896f98b5ecc71c487e9f4e0fa6778c8Creating peer1.org2.example.com
解決辦法
$ docker ps -a
$ docker ps -qa | xargs docker stop
$ docker ps -qa | xargs docker rm
$ docker-compose -f docker-compose.yaml up -d
