进入fabric-samples/test-network目录，执行指令：

./network.sh up -i 2.5

执行完指令能看到fabric已经启动。
在这里插入图片描述

作为第一次Fabric网络体验，网络启动主要包含三个操作，分别是生成配置文件、启动网络和操作网络。

配置文件

使用cryptogen tool生成证书文件（给组织颁发证书）
生成Orderer节点的创世区块genesis.block（创世区块）
生成通道配置交易文件 channel.tx（通道是fabric独有的机制，相当于是一个子链）
为组织1和组织2创建锚节点（锚节点是一个负责对外通讯的节点）

along@DESKTOP-CKPKB5K:~/fabric/fabric-samples/test-network$ ./network.sh up -i 2.5
Starting nodes with CLI timeout of '5' tries and CLI delay of '3' seconds and using database 'leveldb' with crypto from 'cryptogen'
LOCAL_VERSION=v2.5.4
DOCKER_IMAGE_VERSION=v2.5.9
Local fabric binaries and docker images are out of  sync. This may cause problems.
