Fabric Samples
第一步快速起一个Fabric测试网络，官方给了一个非常方便的项目用来学习

| # clone fabric-samples
git clone [email protected]:hyperledger/fabric-samples.git
# 初始化数据仓库（用来放后续的peer、ca等数据）
mkdir ~/data/fabric-data
cd ~/data/fabric-data
# 脚本
要启动一个fabric测试网络需要下载相关镜像，还有一些工具放到了
[fabric-samples](https://github.com/hyperledger/fabric-samples) 这个仓库，官方给了一个一键执行的脚本
curl -sSLO https://raw.githubusercontent.com/hyperledger/fabric/main/scripts/install-fabric.sh && chmod +x install-fabric.sh
./install-fabric.sh -h 可以看一下有什么操作
# clone fabric-samples仓库，下载相关镜像
./install-fabric.sh docker samples
## 下载Fabric二进制执行文件
./install-fabric.sh --fabric-version 2.2.1 binary
