基于fabric1.4.2的区块链浏览器搭建

环境准备

• fabric 1.4.2

• fabric-sample 1.4.2

• blockchain-explorer 0.3.9.5

• go 1.12.8 环境安装

下载安装包

在网址 https://studygolang.com/dl 下载压缩包之后解压提取到Ubuntu中

设置环境配置

vim /etc/profile

export GOROOT=/go

export GOPATH=/Go_WorkSpace

export PATH=$PATH:$GOROOT/bin:$GOPATH/bin

source /etc/profile 使此修改的文件立即生效

go env -w GOPROXY=https://goproxy.cn,direct

• nodejs 8.11.4 环境安装

安装nvm

curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.34.0/install.sh | bash

安装后重启该会话或重新开一个会话即可生效

查看当前支持的版本

nvm ls-remote

安装（同时安装npm）

nvm install 8.11.4

检查node.js安装版本

node -v

检查npm的安装版本

npm -v

切换源

npm install -g nrm

nrm ls

nrm use taobao

• PostgreSQL 10.10 环境安装

apt install postgresql

• Jq jq-1.5-1-a5b5cbe

apt install jq

• docker 19.03.2 环境安装

官方安装脚本

curl -fsSL https://get.docker.com | bash -s docker --mirror Aliyun

配置Docker镜像站

curl -sSL https://get.daocloud.io/daotools/set_mirror.sh | sh -s http://f1361db2.m.daocloud.io

sudo systemctl restart docker.service

• docker-compose 1.24.1 环境安装

docker-compose安装

sudo apt-get install python-pip

sudo pip install docker-compose

查看版本

docker-compose -version

first-network搭建

编译工具

go get github.com/hyperledger/fabric

go get -u github.com/golang/protobuf/protoc-gen-go

cd $GOPATH/src/github.com/hyperledger/fabric

git checkout v1.4.2

sudo apt install libtool libltdl-dev

make release

cd release/linux-amd64 （bin文件下生成了一些必要的工具）

sudo cp -r bin /usr/local （移动到/usr/local下，全局使用）

cd ../..

mkdir -p .build/docker/gotools/

cp -r $GOPATH/bin .build/docker/gotools/

cp -r $GOPATH/src/github.com/hyperledger/fabric/release/linux-amd64/bin/ .build/docker/gotools/

启动网络

go get -u github.com/hyperledger/fabric-samples

cd $GOPATH/src/github.com/hyperledger/fabric-samples/

git checkout v1.4.2

cd first-network

./byfn.sh -m generate

./byfn.sh -m up

区块链浏览器运行实现

导入数据库

cd $GOPATH/src/github.com/hyperledger/blockchain-explorer

git checkout v0.3.9.5

cd app/persistence/fabric/postgreSQL/db

sudo -u postgres ./createdb.sh

cd  $GOPATH/src/github.com/hyperledger/blockchain-explorer/app/platform/fabric/connection-profile

vim first-network.json

将$GOPATH换成自己的路径，将organizations组织的sk证书文件名称换成自己的文件名称，保存退出
