Hyperledger Fabric 1.4 快速环境搭建
自己的硕士研究方向和区块链有关，工程上一直以IBM的Hyperledger Fabric为基础进行开发，对该项目关注也有两年了。目前迎来了Hyperledger Fabric v1.4，这也是Fabric的第一个长期支持版本，因此也比较有代表性，故在此和大家分享一下自己的环境搭建过程。
附上v1.4的官方文档：https://hyperledger-fabric.readthedocs.io/en/release-1.4/。
环境说明:
本人测试环境为腾讯云学生机（1Core/RAM 2G/ROM 50G），CentOS 7.5 64位。
Golang 安装配置（非必须）
下载安装包
mkdir download
cd download
# 从国内站点下载合适的安装包
wget https://studygolang.com/dl/golang/go1.12.4.linux-amd64.tar.gz
解压
tar -C /usr/local/ -xzvf go1.12.4.linux-amd64.tar.gz #解压到/usr/local/go目录下
配置
vim /etc/profile # 配置系统环境变量 # 在最下方插入
# Golang 环境变量
export GOROOT=/usr/local/go
export GOPATH=/root/go
export GOBIN=$GOPATH/bin
export PATH=$PATH:$GOROOT/bin
export PATH=$PATH:$GOPATH/bin #使配置的环境变量生效
source /etc/profile
#检查是否配置正确
go version
说明：Go的环境并非运行的必须条件，但后期调试智能合约可能会用到，而且官网安装说明也提到了需要安装Go。
Node.js 安装配置（非必须）
通过nvm安装Node.js和npm，该步骤也不是运行的必须条件，但后期如果需要node-sdk来开发应用程序的话就需要node环境。（npm源切换可参考npm 淘宝源切换教程）
安装nvm（官方文档：https://github.com/nvm-sh/nvm）
# 安装后重启该会话或重新开一个会话即可生效
curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.34.0/install.sh | bash
通过nvm安装Node.js和npm
# 查看当前支持的版本，fabricv1.4要求只支持8.x
nvm ls-remote
# 安装当前8.x LTS的最新版本（会同时安装npm）
nvm install 8.16.
# 检查node.js安装版本
node -v
# 检查npm的安装版本
npm -v
Docker 安装
Docker安装社区版的就可以，参考官方文档：https://docs.docker.com/install/linux/docker-ce/centos/
参考官方文档的第一种通过仓库安装的方式（傻瓜操作的话第三种直接脚本安装更简单）。
p.s. 由于docker-hub镜像仓库在国外，可能会被墙或者很慢，建议大家参考daocloud加速器配置一下仓库，或者用云服务器的可以参考各家的docker仓库源（阿里Docker镜像库、腾讯Docker镜像库等）。
卸载旧版本
sudo yum remove docker \
docker-client \
docker-client-latest \
docker-common \
docker-latest \
docker-latest-logrotate \
docker-logrotate \
docker-engine
安装docker-ce的必需条件
sudo yum install -y yum-utils \
device-mapper-persistent-data \
lvm2
设置稳定版的仓库
sudo yum-config-manager \
--add-repo \
https://download.docker.com/linux/centos/docker-ce.repo
安装docker-ce
yum install docker-ce docker-ce-cli containerd.io
启动docker
sudo systemctl start docker
测试docker是否安装成功
sudo docker run hello-world
Docker Compose 安装
Fabric中节点容器编排使用的使docker-compose，故需要安装docker-compose。官方文档：https://docs.docker.com/compose/install/
下载docker-compose
sudo curl -L "https://github.com/docker/compose/releases/download/1.24.0/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
为docker-compose配置执行权限
sudo chmod +x /usr/local/bin/docker-compose
检查是否安装成功
docker-compose -v
源码获取
通过go get 的方式获取源码，配合git切换分支
获取fabric源码
# 获取fabric源码
go get -u github.com/hyperledger/fabric
# 进入目录 切换分支
cd go/src/github.com/hyperledger/fabric
git checkout v1.4.1
获取fabric-sample源码
go get github.com/hyperledger/fabric-samples
# 进入目录，切换分支
cd go/src/github.com/hyperledger/fabric-samples/
git checkout v1.4.1
获取镜像和二进制文件
我们通过fabric-sample测试
通过脚本获取docker镜像和可执行文件（建议事先配置好docker仓库）
cd go/src/github.com/hyperledger/fabric-samples/scripts/
#此处可能因为网络问题执行时间比较久
bash bootstrap.sh
运行测试
通过fabric-sample中first-network示例测试，执行了一个A和B转账，中间多次查询余额的一个过程。
docker运行需要权限，最好用root身份运行。
找到first-network示例
cd go/src/github.com/hyperledger/fabric-samples/first-network
