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

nnodejs加速器 淘宝NPM镜像

golang国内镜像 Go中文网

环境变量设置

#jdk
export JAVA_HOME=/opt/jdk1.8.0_161
export CLASSPATH=${JAVA_HOME}/lib:${JAVA_HOME}/jre/lib
export PATH=${JAVA_HOME}/bin:${PATH}
#maven
export MAVEN_HOME=/opt/apache-maven-3.5.3
export PATH=${MAVEN_HOME}/bin:${PATH}
#

#全局命令
export SHELL_HOME=/opt/shell
export PATH=${SHELL_HOME}:${PATH}
#nodejs
export NODE_HOME=/opt/node-v8.11.3-linux-x64
export NODE_PATH=${NODE_HOME}/lib/node_modules
export PATH=${NODE_HOME}/bin:${PATH}
alias cnpm="npm --registry=https://registry.npm.taobao.org --cache=${HOME}/.npm/.cache/cnpm --disturl=https://npm.taobao.org/dist --userconfig=${HOME}/.cnpmrc"
#go
export GOPATH=${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

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

使用docker查看镜像

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

关闭执行

sudo ./network_setup.sh down

*注意:*使用sudo,不然order会启动异常
