./network_setup.sh up
该指令做了一下操作
1.编译生成Fabric公私钥、证书的程序,程序在目录:fabric/release/linux-amd64/bin
2.基于configtx.yaml生成创世区块和通道相关信息,并保存在channel-artifacts文件夹。
3.基于crypto-config.yaml生成公私钥和证书信息,并保存在crypto-config文件夹中。
4.基于docker-compose-cli.yaml启动1Orderer+4Peer+1CLI的Fabric容器。
5.在CLI启动的时候,会运行scripts/script.sh文件,这个脚本文件包含了创建Channel,加入Channel,安装Example02,运行Example02等功能。
运行完如果出现下图所示,说明整个Fabric网络已经通了.
Fabric提供了SDK和CLI两种交互方式,我们使用的是CLI 。
使用官方提供的小例子进行测试,在官方例子中,channel名字是mychannel,链码(智能合约)的名字是mycc。
首先要登录到CLI这个容器中,才能执行Fabric的CLI命令:
docker exec -it cli bash
这时用户名变为root@44084971aff7,当前目录变为/opt/gopath/src/github.com/hyperledger/fabric/peer#,接着可执行peer命令,体验区块链的命令行使用方式。
root@44084971aff7:/opt/gopath/src/github.com/hyperledger/fabric/peer# peer chaincode query -C mychannel -n mycc -c '{"Args":["query","a"]}'
结果:
Query Result: 90
这里90就是a账户的余额
让b账户向a账户转账10:
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 -c '{"Args":["invoke","a","b","20"]}'
再次执行查询(因为转账操作了2次所以此处是50)
root@c259da3de4d1:/opt/gopath/src/github.com/hyperledger/fabric/peer# peer chaincode query -C mychannel -n mycc -c '{"Args":["query","a"]}'
直接执行
exit
关闭Fabric
cd ~/go/src/github.com/hyperledger/fabric/examples/e2e_cli
./network_setup.sh down
原因:未安装wget、curl
解决
yum install -y wget
yum install -y curl
yum install -y git
Failed connect to github-production-release-asset-2e65be.s3.amazonaws.com:443; Connection timed out
原因: 该地址(github-production-release-asset-2e65be.s3.amazonaws.com) 需要的一些下载的访问被 国内屏蔽了
解决:在hosts中加配置
ping github-production-release-asset-2e65be.s3.amazonaws.com
vi /etc/hosts
新增如下配置:
