安装fabric 1.4版本
刚开始接触区块链，跟着网上的教程搭建hyperledger fabric ，下载的是1.0版本，最近运行GitHub上的例子，发现有些需要高的版本，所以决定更新版本到1.4，看了官网的更新文档都是相近版本的更新，没有找到从1.0更新到1.4的，所以决定按照官网文档指导重新安装。
其实掌握了搭建hyperledger fabric 1.0，安装1.4是很简单的，主要注意一下删除之前的镜像，重新安装就可以。
删除镜像指令：
$ docker rm -f $(docker ps -aq)
$ docker rmi -f $(docker images -q)
参考https://hyperledger-fabric.readthedocs.io/en/latest/install.html
一、准备
要求版本：
go1.11 以及以上版本
docker 17.06.2-ce 以及以上版本
docker-compose 1.14.0 以及以上版本
go和docker的版本都很新，这里就不再赘述了。具体的安装方法可以参考搭建hyperledger-fabric环境
更新docker-compose
安装fabric源码
lqr@lqr-VirtualBox:~$ mkdir -p ~/go/src/github.com/hyperledger
lqr@lqr-VirtualBox:~$ cd ~/go/src/github.com/hyperledger
lqr@lqr-VirtualBox:~/go/src/github.com/hyperledger$ git clonehttps://github.com/hyperledger/fabric.git
docker 镜像安装
进入到fabric目录中，然后输入
$ cdgo/src/github.com/hyperledger/fabric
$ curl -sSL https://bit.ly/2ysbOFE | bash -s -- 1.4.0
$ docker images
二、构建第一个网络
$ cd fabric-samples/first-network
byfn.sh脚本的帮助文档：
根据配置文件生成各种文件
$ sudo ./byfn.sh -m generate
