前提条件
1、安装 curl
2、安装 docker 和 docker compose
版本查看
$ docker --version
$ docker-compose --version
3、安装go
设置环境变量如下
$ vim ~/.bashrc
export GOPATH=/home/lqs/go
export PATH=$PATH:$GOPATH/bin
4、安装Python
Fabric Node.js SDK需要使用 Python 2.7版本才能成功完成 npm install 操作，使用以下命令安装
$ sudo apt-get install python
$ python --version
安装示例、二进制文件和 Docker 镜像
1、克隆 hyperledger/fabric-samples 仓库
进入网址克隆 hyperledger/fabric-samples 仓库
$ git clone https://github.com/hyperledger/fabric-samples
2、进入fabric-samples目录执行以下命令
$ 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
//可只执行前半部分，不指定版本，系统会自动下载最新版本（该命令会下载很多镜像，耗时较长）
$ ./scripts/bootstrap.sh [version] [ca version] [thirdparty_version]
$ ./scripts/bootstrap.sh 1.4.1 1.4.1 0.4.18
下载好之后再 fabric-samples 目录下会生成新的文件夹 bin 和 config
文件实例如下
$ tree bin/
bin
├── configtxgen
├── configtxlator
├── cryptogen
├── discover
├── fabric-ca-client
├── idemixgen
├── orderer
└── peer
$ tree config
config/
├── configtx.yaml
├── core.yaml
└── orderer.yaml
3、环境变量配置
添加 bin 文件的路径到PATH里面
$ vim ~/.bashrc
export PATH=/home/lqs/fabric-samples/bin:$PATH
搭建网络
$ cd first-network
初始化网络
$ ./byfn.sh generate
Generating certs and genesis block for channel 'mychannel' with CLI timeout of '10' seconds and CLI delay of '3' seconds

运行示例代码
现在再次启动网络运行 ./byfn.sh ，然后进入容器执行示例代码
进入容器
$ docker exec -it cli bash
查询 a 值
// 因为在初始化时已经执行过一次，现在的 a 值查询结果为90
$ peer chaincode query -C mychannel -n mycc -c '{"Args":["query","a"]}'
执行转账功能（ a 转 10 到 b）
// 该代码为将a的10转给b ，执行一次之后再查询a可看到还剩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"]}'
退出容器并关闭网络
$ exit
$ ./byfn.sh down
可能会出现的问题
1、docker ps 错误
当执行 $ docker ps 时出现以下错误，这是由于docker守护进程启动的时候，会默认赋予名字为docker的用户组读写unix socket的权限， 因此只要创建docker用户组，并将当前用户加入到docker用户组中，那么当前用户就有权限访问unix socket了，进而就可以执行docker相关命令
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
采用以下命令解决
$ sudo groupadd docker # 添加用户组
$ sudo gpasswd -a $USER docker # 将登录用户加入到docker用户组中
$ newgrp docker # 更新用户组
$ docker ps # 测试docker命令是否可用
2、docker 镜像未关闭错误
当启动网络时出现以下错误，是因为没有 down 掉或未完全关闭，关闭 docker 进程即可
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
解决办法
$ docker ps -a
$ docker ps -qa | xargs docker stop
$ docker ps -qa | xargs docker rm
$ docker-compose -f docker-compose.yaml up -d
