1.准备环境
- VMware Workstation
- ubuntu 16.04 LTS
- 安装Go，安装方法可以参考《Golang入门学习》
- 安装Docker，安装方法可以参考《Get Docker CE for Ubuntu》
- 安装docker compose
2.下载Fabric源码
root@ubuntu:/opt/go-pkg/src/github.com# mkdir hyperledger
root@ubuntu:/opt/go-pkg/src/github.com# cd hyperledger
# 开始下载
root@ubuntu:/opt/go-pkg/src/github.com/hyperledger# git clone https://github.com/hyperledger/fabric.git
root@ubuntu:/opt/go-pkg/src/github.com/hyperledger# cd fabric
root@ubuntu:/opt/go-pkg/src/github.com/hyperledger/fabric# git checkout v1.3.03.官网入门程序
链码目录：github.com/hyperledger/fabric/examples/chaincode/go
3.1.下载镜像
# 启动docker服务
root@ubuntu:/opt/go-pkg/src/github.com/hyperledger/fabric/examples/e2e_cli# systemctl start docker
# 执行download-dockerimages.sh脚本下载相关镜像
root@ubuntu:/opt/go-pkg/src/github.com/hyperledger/fabric/examples/e2e_cli# source download-dockerimages.sh -c latest -f latest如果下载失败，可以修改脚本指定具体镜像Tag，文章写作时最新版本，fabric-peer/tags：1.3.0，fabric-kafka/tags：0.4.14。镜像详情可以参考：https://hub.docker.com/r/hyperledger/

3.2.创建公私钥、证书、创世区块及通道配置
# 执行示例脚本
root@ubuntu:/opt/go-pkg/src/github.com/hyperledger/fabric/examples/e2e_cli# source generateArtifacts.sh mychannel
执行结果：
- ./channel-artifacts目录下会生成channel.tx、genesis.block、Org1MSPanchors.tx、Org2MSPanchors.tx文件。
- 生成crypto-config目录及子目录和文件。
- 由docker-compose-e2e-template.yaml模板生成docker-compose-e2e.yaml文件并自动填充CA1_PRIVATE_KEY和CA2_PRIVATE_KEY内容。
具体相关命令及说明可以参考generateArtifacts.sh脚本，内容如下：

echo 说明：
注意修改下面端口，因为cli跟e2e不在一个docker compose里，需要通过容器映射宿主机端口访问，详情可以查看examples/e2e_cli/base/docker-compose-base.yaml：
CORE_PEER_ADDRESS=peer1.org1.example.com:8051
CORE_PEER_ADDRESS=peer0.org2.example.com:9051
CORE_PEER_ADDRESS=peer1.org2.example.com:10051
- 为了方便测试注释掉了后面3个方法调用。
- 主要方法和步骤，创建Channel、更新Anchor、加入Channel、安装Chaincode、实例化Chaincode、Chaincode查询、交易
执行完上面脚本后，通过用下面命令直接查询：
root@b5107a3b6f6b:/opt/gopath/src/github.com/hyperledger/fabric/peer# peer chaincode query -C mychannel -n mycc -c '{"Args":["query","a"]}'输出结果：
说明：脚本执行时查询a=100，因为实例初始值a=100。交易后a向b转了10，所以上面查询结果a=90。b=210，这里不在贴图可以自己测试体验。
4.问题
- 操作中可能遇到权限异常错误，可以考虑停止并删除所有容器后删除channel-artifacts和crypto-config目录内容，重新按步骤操作。
- 注意宿主机用户跟容器用户操作权限，这里都是用的root用户。
5.Docker命令
# 停止并删除所有容器
$ docker rm -f $(docker ps -a -q)
