当我跟着书上的步骤一起做时，并没有得到书上的结果，并且会出现许多错误，于是我选择跟随hyperledger开发文档来做。
1.开始之前的准备
2.安装示例、二进制和 Docker 镜像
3.# 使用Fabric的测试网络
当我运行
./network.sh down
出现如下错误：(具体原因未知)
root@lennon-System-Product-Name:/home/lennon/桌面/fabric-samples/test-network# ./network.sh down

出现了，好像是因为我之前跟着书上的来做docker中创建过容器，需要移出或者重命名之前那个才行。
然后，我输入命令
docker ps
查看本地系统中运行的容器信息：

这说明我之前已经创建过了容器，我需要先将这些删除掉，但是我当时并没有这样做，而是运行了创建通道的命令
./network.sh createChannel
然后就出现了error

Error: failed to create deliver client for orderer: orderer client failed to connect to localhost:7050: failed to create new connection: context deadline exceeded
Channel creation failed
Create channel failed
然后我运行删除之前容器的命令：
./network.sh down
出现如下提示：

提示我没有能删除的容器和镜像。
此时我以为已经删除掉了之前的容器，然后就尝试创建通道
./network.sh up createChannel -c mychannel
又出现之前的错误

Error: failed to create deliver client for orderer: orderer client failed to connect to localhost:7050: failed to create new connection: context deadline exceeded

这说明之前的容器还是没有删除掉，输入查询容器命令(此命令只显示id)：
docker ps -aq
输出结果是：

发现还是有容器，没有删除掉
最后使用
docker system prune
终于删除掉了
