fabric探秘系列-1 运行fabric测试网络
一、前言
Hyperledger Fabric is a platform for distributed ledger solutions, underpinned by a modular architecture delivering high degrees of confidentiality, resiliency, flexibility and scalability.
二、准备
| 项目 | 版本 | 备注 |
| centos | 7.7 | CentOS Linux release 7.7.1908 (Core) |
| Go运行环境 | 1.15.7 | PATH 环境变量：/usr/local/go/bin GOPATH环境变量：/home/admin/go 部署步骤参考文章：https://blog.csdn.net/jeikerxiao/article/details/106708145 |
| docker环境 | 20.10.3 | 部署步骤参考文章：https://www.runoob.com/docker/centos-docker-install.html 镜像加速配置文章：https://www.runoob.com/docker/docker-mirror-acceleration.html |
| docker-compose | 1.26.2 | 部署步骤参考文章：https://www.runoob.com/docker/docker-compose.html 安装1.28.0版本时遇到【Error loading Python lib '/tmp/_MEIDfblYM/libpython3.9.so.1.0': dlopen: /lib64/libc.so.6: version `GLIBC_2.28' not found (required by /tmp/_MEIDfblYM/libpython3.9.so.1.0)】的情况，需要升级glibc参考这篇文章：https://bbs.huaweicloud.com/blogs/238962 |
| git | 1.8.3.1 | yum install -y git |
三、下载fabric v2.2源码
[root@localhost hyperledger]# pwd
/home/admin/go/src/github.com/hyperledger
[root@localhost hyperledger]# git clone https://github.com/hyperledger/fabric.git

[root@localhost fabric]# git checkout -b 2.2 origin/release-2.2
Branch 2.2 set up to track remote branch release-2.2 from origin.
Switched to a new branch '2.2'

四、实践fabric样例
在搭建fabric环境前，确保先成功启动了docker：systemctl start docker
1、下载样例程序
运行bootstrap.sh脚本，会执行3个任务：下载fabric-samples代码，下载二进制文件（bin目录下的可执行文件），下载docker镜像
[root@localhost opt]# cd /home/admin/go/src/github.com/hyperledger/fabric/scripts/
[root@localhost scripts]# ./bootstrap.sh

分析此脚本执行过程：
1、判断子目录organizations\peerOrganizations是否存在，不存在则创建【组织】
2、构建并启动nignx容器【docker-compose -f docker/docker-compose-test-net.yaml up -d 2>&1】
3、判断是否启动失败【docker ps -a】
最终的效果：two Organization peers and an ordering service node.
五、问题
容器没有成功启动
