本次环境还是基于Vagrant，创建1peer节点1组织1个排序节点的fabric网络，其实这个和first-network差不多，只是使用手动的方式完成fabric网络的部署。
实验环境搭建
创建虚拟机
-
创建vagrant配置文件，这里指定操作系统为centos7
vagrant init centos/7
-
编写启动脚本 bootstrap.sh
#!/usr/bin/bash sudo su echo "nameserver 8.8.8.8" >> /etc/resolv.conf sleep 3s yum install -y epel-release yum install -y vim yum install -y golang yum remove docker docker-common docker-selinux docker-engine yum install -y yum-utils device-mapper-persistent-data lvm2 yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo yum makecache fast yum -y install docker-ce yum -y install docker-compose service docker start mkdir -p /etc/docker echo {\"registry-mirrors\": [\"https://8w1wqmsz.mirror.aliyuncs.com\"]} > /etc/docker/daemon.json service docker restart echo "export GOPROXY=https://goproxy.io,direct" >> /etc/profile -
