如何搭建Hyperledger fabric网络

1、安装docker

1.1卸载旧的版本

        yum remove docker \
                  docker-client \
                  docker-client-latest \
                  docker-common \
                  docker-latest \
                  docker-latest-logrotate \
                  docker-logrotate \
                  docker-engine
1.2下载需要的安装包

        yum install -y yum-utils

1.3设置镜像的仓库

yum-config-manager \
    --add-repo \
    https://download.docker.com/linux/centos/docker-ce.repo  #国外的地址
# 设置阿里云的Docker镜像仓库
yum-config-manager \
  --add-repo \
    https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo  #国内的地址

1.4更新yum软件包索包

  yum makecache fast

1.5安装docker相关的配置

docker-ce 是社区版，docker-ee 企业版

yum install docker-ce docker-ce-cli containerd.io

1.6启动Docker

systemctl start docker

# 查看当前版本号，是否启动成功

docker version

# 设置开机自启动

systemctl enable docker

2.配置阿里云镜像

 3.安装docker-compse

3.1安装：

sudo curl -L https://get.daocloud.io/docker/compose/releases/download/1.26.2/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compos

3.2授权：

# 将可执行权限应用于该二进制文件
sudo chmod +x /usr/local/bin/docker-compose

3.3测试：

#测试
docker-compose --version

4.安装go语言环境

4.1下载并安装Go语言环境

# cd /opt
# mkdir golang
# cd golang
# yum install wget
# wget https://studygolang.com/dl/golang/go1.14.3.linux-amd64.tar.gz
# tar -zxvf go1.14.3.linux-amd64.tar.gz

4.2配置Go语言环境变量

vi /etc/profile
#添加如下内容到/etc/profile后面
export GOPATH=/opt/gopath
export GOROOT=/opt/golang/go
export PATH=$GOROOT/bin:$PATH
#生效配置文件
source /etc/profile

5.安装git

yum -y install git

附带的插件方便查看

#方便查看层级关系
yum -y install tree
#高亮编辑
yum -y install vim-enhanced

6.Fabric安装

6.1创建生产目录

mkdir -p $GOPATH/src/github.com/hyperledger/
cd $GOPATH/src/github.com/hyperledger/

6.2通过git克隆源码：

git clone https://github.com/hyperledger/fabric.git  #优先
#若github下载太慢，可以将https改成git
git clone git://github.com/hyperledger/fabric.git  #(备选1)
#也可以用国内镜像
git clone https://github.com.cnpmjs.org/hyperledger/fabric.git #(备选2)
cd fabric

6.3切换分支

git checkout -b release-1.4 origin/release-1.4
#检查一下分支
git branch

6.4修改编译环境脚本bootstrap.sh

cd /opt/gopath/src/github.com/hyperledger/fabric/scripts
vim bootstrap.sh

加入相应的二进制文件

6.5启动相关的二进制

./boostrp.sh

下载相关的fabric的组件包括 tools,peer,orderer,baseos,ca,ccenv

 6.6构建第一个区块链网络

#cd /opt/gopath/src/github.com/hyperledger/fabric/scripts/fabric-samples/first-network
#./byfn.sh -m generate 生产相关的证书

./byfn,sh -m up 启动测试网络。
