更新fabric到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

启动网络

$ sudo ./byfn.sh up

出现上图表示成功啦！

关闭网络

$ sudo ./byfn.sh down

提示：
如果出现文件夹锁住的情况可以通过一下指令修改权限，例如修改 fabric-sample的权限

lqr@lqr-VirtualBox:~/go/fabric-samples$ sudo chmod -R 777 fabric-samples
