网络启动

以下操作均于centos7.6虚拟机环境使用root用户完成，可以根据具体需求进行选择实体机与不同用户选择

该教程（搭建第一个fabric网络1.4.2版本）基本完全基于官方文档进行，适用于缺乏了解的新手与感兴趣的人群

1.docker-compose配置文件修改

我们使用fabric-sample工程提供的docker-compose配置文件进行相应修改：

以下展示了机器1的相关启动配置，其他机器可以根据其进行相关修改

• docker-compose-cli.yaml（注意容器名称、cli环境相关挂载、网络名称）

2.网络启动

分别在各个机器相关位置执行docker-compose命令即可启动：

export IMAGE_TAG=1.4.2 && export SYS_CHANNEL=test-sys-channel && export COMPOSE_PROJECT_NAME=net && export COUCHDB_IMAGE_TAG=0.4.15 && docker-compose -f docker-compose-cli.yaml up -d

关闭命令：

export IMAGE_TAG=1.4.2 && export SYS_CHANNEL=test-sys-channel && export COMPOSE_PROJECT_NAME=net && export COUCHDB_IMAGE_TAG=0.4.15 && docker-compose -f docker-compose-cli.yaml down

网络启动前确保centos的selinux关闭，否则可能出现问题。
