部署 Hyperledger Fabric v1.4 Solo模式
介绍简单Fabric，Fabric 是 Hyperledger 超级账本中的一个子项目，由 Linux 基金会主办。它提供了一个开发区块链应用程序的框架。它的部署架构有两种模式：Solo模式，即单Orderers架构；Kafka模式，即多Orderers架构。
以下我们部署一个Solo模式的测试环境：
1、基础环境准备
1、主机一台
最低配：2C4G
推荐配置：4C8G
2、安装Docker
# 列出所有的docker版本
yum list docker-ce --showduplicates | sort -r
# 安装指定的docker版本
yum install docker-ce-<VERSION_STRING>
3、安装Docker-compose
curl -L https://github.com/docker/compose/releases/download/1.24.0/docker-compose-`uname -s`-`uname -m` -o /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose
4、安装Python3
# 下载python3
wget https://www.python.org/ftp/python/3.6.3/Python-3.6.3.tgz
# 解压、编译即可
5、安装Go
# 下载Go
wget https://studygolang.com/dl/golang/go1.10.1.linux-amd64.tar.gz
# 解压、设置环境变量
export GOROOT=/root/go
export GOPATH=/root/gopath
export PATH=$PATH:$GOROOT/bin:$GOPATH/bin
6、安装nodejs、npm
# 下载nodejs
wget https://npm.taobao.org/mirrors/node/v8.0.0/node-v8.0.0-linux-x64.tar.xz
# 解压、配置软链接
ln -s /root/node-v8.0.0-linux-x64/bin/node /usr/local/bin/node
ln -s /root/node-v8.0.0-linux-x64/bin/npm /usr/local/bin/npm
2、安装Fabric网络
1、Fabric源码下载
git clone https://github.com/hyperledger/fabric-samples
2、下载需要的二进制执行文件
wget https://nexus.hyperledger.org/content/repositories/releases/org/hyperledger/fabric/hyperledger-fabric/linux-amd64-1.4.0/hyperledger-fabric-linux-amd64-1.4.0.tar.gz
# 解压、配置PATH
export PATH=$PATH:/root/fabric-samples/bin
3、生成网络工件
# 进入到First-Network目录，执行如下目录
./byfn.sh generate
输出结果如下：
Generating certs and genesis block for channel 'mychannel' with CLI timeout of '10' seconds and CLI delay of '3' seconds

此处必须保证下载的Fabric源码和二进制文件工具版本一致，否则会报如下错

4、创建启动Fabric网络
./byfn.sh up
# 此步骤需要pull镜像执行较长时间。可以提前使用/scripts/bootstrap.sh脚本来pull需要的镜像
如果Docker和Docker-Compose的版本差距过大，那么这一步也会报如下错
