HyperLedger Fabric
第一步 初始化开发环境
系统信息:
Linux ubuntu 4.15.0-29-generic
go version go1.10.1 linux/amd64
Docker version 18.06.0-ce-dev
docker-compose version 1.21.1
node-v8.11.3
npm 5.6.0
java version "1.8.0_161"
Apache Maven 3.5.3
1 基础环境配置加速器
docker加速器 docker-cn

#go
export GOPATH=${HOME}/go
export PATH=${GOPATH}/bin:${PATH}
#fabric
export PATH=${HOME}/fabric-samples/bin:${PATH}*注意:*具体配置请配置成自己的路径
2 快速安装
为了快速构建,不用该太多脚本路径,请保持在$HOME目录下
cd ~/
curl -sSL https://raw.githubusercontent.com/hyperledger/fabric/release-1.3/scripts/bootstrap.sh -o bootstrap.sh chmod +x bootstrap.sh ./bootstrap.sh
如果github下载速度慢:
sed -i 's#https://github.com/hyperledger/fabric-samples.git#git@gitee.com:fansinZhao/fabric-samples.git#g' bootstrap.sh
如果其他资源下载安装包慢,请访问 fabric离线包
耐心等待下载,下载成功后显示如下
===> List out hyperledger docker images hyperledger/fabric-ca 1.2.0 66cc132bd09c 4 weeks ago 252MB hyperledger/fabric-ca latest 66cc132bd09c 4 weeks ago 252MB hyperledger/fabric-tools 1.2.0 379602873003 4 weeks ago 1.51GB hyperledger/fabric-tools latest 379602873003 4 weeks ago 1.51GB hyperledger/fabric-ccenv 1.2.0 6acf31e2d9a4 4 weeks ago 1.43GB hyperledger/fabric-ccenv latest 6acf31e2d9a4 4 weeks ago 1.43GB hyperledger/fabric-orderer 1.2.0 4baf7789a8ec 4 weeks ago 152MB hyperledger/fabric-orderer latest 4baf7789a8ec 4 weeks ago 152MB hyperledger/fabric-peer 1.2.0 82c262e65984 4 weeks ago 159MB hyperledger/fabric-peer latest 82c262e65984 4 weeks ago 159MB hyperledger/fabric-zookeeper 0.4.10 2b51158f3898 5 weeks ago 1.44GB hyperledger/fabric-zookeeper latest 2b51158f3898 5 weeks ago 1.44GB hyperledger/fabric-kafka 0.4.10 936aef6db0e6 5 weeks ago 1.45GB hyperledger/fabric-kafka latest 936aef6db0e6 5 weeks ago 1.45GB hyperledger/fabric-couchdb 0.4.10 3092eca241fc 5 weeks ago 1.61GB hyperledger/fabric-couchdb latest 3092eca241fc 5 weeks ago 1.61GB
执行完需要刷新一下环境变量
source /etc/profile
或者注销重启
3 官方例子1 "helloword"
cd ~/fabric-samples/first-network ./byfn.sh generate ./byfn.sh up
一切顺利的话,显示下面的内容
===================== Query successful on peer1.org2 on channel 'mychannel' ===================== ========= All GOOD, BYFN execution completed ===========
关闭的话
./byfn.sh down _____ _ _ ____ | ____| | \ | | | _ \ | _| | \| | | | | | | |___ | |\ | | |_| | |_____| |_| \_| |____/
4 官方例子2 IBM的marble
cd ~/fabric-samples/fabcar ./startFabric.sh npm install npm audit fix node enrollAdmin.js node registerUser.js node invoke.js node query.js
正常执行完毕后,会在目录$HOME/fabric-samples/fabcar/hfc-key-store下有文件存在.类似下面
zhaofeng[@ubuntu](https://my.oschina.net/u/555627):~/fabric-samples/fabcar$ tree hfc-key-store/ hfc-key-store/ ├── 51da36ca8deb87c1cefa30ae686c5addb67cff53739b859c63ba708581cb6640-priv ├── 51da36ca8deb87c1cefa30ae686c5addb67cff53739b859c63ba708581cb6640-pub ├── 95d4a6c61e4b503269b5d525e2c876c22cf0038bfa8b3396f3d5f8a5c53055a8-priv ├── 95d4a6c61e4b503269b5d525e2c876c22cf0038bfa8b3396f3d5f8a5c53055a8-pub ├── admin └── user1 0 directories, 6 files
使用docker查看镜像
zhaofeng[@ubuntu](https://my.oschina.net/u/555627):~/fabric-samples/fabcar$ docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES f2aa240d4298 dev-peer0.org1.example.com-marbles-v4-f704f1411b52539123b5920f0c3d59dc4c88aa255a82cd002be690a5a6a8150e "chaincode -peer.add…" 8 hours ago Up 8 hours dev-peer0.org1.example.com-marbles-v4 127aac75b9bb dev-peer0.org1.example.com-fabcar-1.0-5c906e402ed29f20260ae42283216aa75549c571e2e380f3615826365d8269ba "chaincode -peer.add…" 8 hours ago Up 8 hours dev-peer0.org1.example.com-fabcar-1.0 d9d7172e9043 hyperledger/fabric-tools "/bin/bash" 8 hours ago Up 8 hours cli 04bcf025450c hyperledger/fabric-peer "peer node start" 8 hours ago Up 8 hours 0.0.0.0:7051->7051/tcp, 0.0.0.0:7053->7053/tcp peer0.org1.example.com 2ddca7b27e38 hyperledger/fabric-ca "sh -c 'fabric-ca-se…" 8 hours ago Up 8 hours 0.0.0.0:7054->7054/tcp ca.example.com 5454667897c4 hyperledger/fabric-couchdb "tini -- /docker-ent…" 8 hours ago Up 8 hours 4369/tcp, 9100/tcp, 0.0.0.0:5984->5984/tcp couchdb 0a23230a291e hyperledger/fabric-orderer "orderer" 8 hours ago Up 8 hours 0.0.0.0:7050->7050/tcp orderer.example.com
注意:npm install执行报权限错误,使用npm install --unsafe-perm=true
到此步骤,fabric local环境已经初始化.下面安装IBM marbles
cd ~ git clone git@github.com:IBM-Blockchain/marbles.git --depth 1
修改配置文件marbles/config/connection_profile_local.json
"client": {
"organization": "Org1MSP",
"credentialStore": {
"path": "/$HOME/.hfc-key-store"
}
}将$HOME/fabric-samples/fabcar/hfc-key-store复制一份到$HOME/.hfc-key-store,这一步是解决一个bug
cp -r $HOME/fabric-samples/fabcar/hfc-key-store $HOME/.hfc-key-store
修改配置文件marbles/config/marbles_local.json
"use_events": false,
不然系统会报错. 修改完配置文件,就可以执行安装代码了
cd marbles/ npm install npm audit fix cd scripts/ node install_chaincode.js node instantiate_chaincode.js npm install gulp -g npm install npm audit fix gulp marbles_local
正常启动后访问http://localhost:3001/home. 其他细节参考官方文档
5 官方源码安装
下载主线代码
cd ~ git clone https://github.com/hyperledger/fabric.git
或者 cd ~ git clone https://gitee.com/fansinZhao/fabric.git
下载完毕后 cd fabric git checkout -b v1.2.0 cp -r ../fabric $GOPATH/src/github.com/hyperledger/fabric sudo ./network_setup.sh up
正常显示下面内容
