本文是学习官网部署智能合约至通道示例中，第一步启动网络同时创建通道，针对返回结果进行分析，执行命令如下：
[root@localhost test-network]# ./network.sh up createChannel以下的返回结果，浅蓝色字体及图片为分析备注，并根据一些备注生成了目录：

Creating channel 'mychannel'.
If network is not up, starting nodes with CLI timeout of '5' tries and CLI delay of '3' seconds and using database 'leveldb' with crypto from 'cryptogen'

LOCAL_VERSION=2.3.3

使用cryptogen工具（密码学工具）生成证书
# cryptogen工具位置
/home/gopath/src/github.com/hyperledger/fabric/scripts/fabric-samples/bin/cryptogen
cryptogen工具是根据crypto-config-xxx.yaml配置文件为每个网络中的实体创建X.509格式的证书；在crytogen工具创建证书时，将会使用leveldb状态数据库，leveldb是默认嵌入在peer节点的状态数据库。
配置文件的位置如图，
查看crypto-config-org1.yaml文件
上面的配置文件中，EnableNodeOUs设置为true时，将在msp目录中生成config.yaml文件
查看crypto-config-orderer.yaml文件
