    一、启动网络步骤

    • 1.生成组织结构 sudo ./byfn.sh -m generate

      • 生成组织结构及身份证书（保存在当前目录的crypto-config目录下）

      • 生成orderer初始区块配置文件（保存在当前的目录的channel-artifacts目录下 ，genesis.block）

      • 生成应用通道交易配置文件（保存在当前的目录的channel-artifacts目录下，channel.tx）

      • 组织中锚节点更新配置文件（保存在当前的目录的channel-artifacts目录下，Org1MSPanchors.tx、Org2MSPanchors.tx）

        • 检查当前组织中新加入的节点
        • 跨组织数据交换

    • 2.启动网络 sudo ./byfn.sh -m up

      • 进入cli容器
      • 创建应用通道（根据指定的应用通道配置文件）
      • 将制定的节点加入到应用通道中
      • 在制定的节点中安装链码
      • 将安装的链码进行实例化
      链码必须在制定的节点上安装
指定的节点安装链码成功后，需要对链码进行实例化，但是实例化只需要执行一次即可
在实例化链码的时候，指定-P 指定策略规则
      • 调用链码对账本数据进行操作

    • 3.关闭网络 sudo ./byfm.sh down

      
删除生成的所有组织结构及身份证书目录
删除生成的channel-artifacts/目录下的四个配置文件

    二、具体操作过程

    进入fabric 目录中

    $ cd fabric-samples/first-network

    在first-network目录下有两个自动化脚本byfn.sh和eyfn.sh, 这两个脚本的启动顺序是先执行byfn.sh再执行eyfn.sh（eyfn.sh不是必须的）

    查看帮助信息:

    $ ./byfn.sh --help
    启动模式

     <mode> - one of 'up', 'down', 'restart' or 'generate'
      - 'up' - bring up the network with docker-compose up
      - 'down' - clear the network with docker-compose down
      - 'restart' - restart the network
      - 'generate' - generate required certificates and genesis block
      - 'upgrade'  - upgrade the network from v1.0.x to v1.1
-c <channel name> - channel name to use (defaults to "mychannel")
    -t <timeout> - CLI timeout duration in seconds (defaults to 10)
    -d <delay> - delay duration in seconds (defaults to 3)
    -f <docker-compose-file> - specify which docker-compose file use (defaults to docker-compose-cli.yaml)
    -s <dbtype> - the database backend to use: goleveldb (default) or couchdb
    -l <language> - the chaincode language: golang (default) or node
    -i <imagetag> - the tag to be used to launch the network (defaults to "latest")





    
up：启动网络
down：关闭网络
restart：重新启动
generate：生成网络环境中的组织结构及相应的证书及创世块
upgrade：将网络从1.0升级到1.1

-c：用于指定channelName，默认值"mychannel"
-t：CLI timeout时间，默认值10
-d：延迟启动，默认值3
-f：使用指定的网络拓扑结构文件，默认使用docker-compose-cli.yaml
-s：指定使用的数据库，可选 go leveldb或couchdb
-l：指定chaincode使用的语言，可选golang 或node
-i：指定镜像tag，默认 "latest"

    生成证书和密钥

    为各种网络实体生成所有证书和密钥，用于引导订购服务以及配置通道所需的一系列配置事务
    生成网络环境中的组织结构及相应的证书及创世块

    $ sudo ./byfn.sh -m generate

    执行结果：

    1命令：生成组织结构和身份证书   使用当前路径./crypto-config.yaml这个配置文件生成
+ cryptogen generate --config=./crypto-config.yaml
生成了两个peer组织：
org1.example.com
org2.example.com

/home/chelsea/hyfa/fabric-samples/first-network/../bin/configtxgen

2命令：生成orderer初始区块 profile指定配置模版。 outputBlock生成的创世区块的路径及名称
+ configtxgen -profile TwoOrgsOrdererGenesis -outputBlock ./channel-artifacts/genesis.block

3命令：生成通道的配置交易文件profile指定模版名称outputCreateChannelTx生成通道的配置文件保存路径及文件名称
+ configtxgen -profile TwoOrgsChannel -outputCreateChannelTx ./channel-artifacts/channel.tx -channelID mychannel

4.1命令：生成org1锚节点更新文件 profile指定模版名称，outputAnchorPeersUpdate指定输出路径及文件名称 asOrg指定哪一个组织ID
+ configtxgen -profile TwoOrgsChannel -outputAnchorPeersUpdate ./channel-artifacts/Org1MSPanchors.tx -channelID mychannel -asOrg Org1MSP

4.2命令：生成org2锚节点组织名称变化，文件名称变化
+ configtxgen -profile TwoOrgsChannel -outputAnchorPeersUpdate ./channel-artifacts/Org2MSPanchors.tx -channelID mychannel -asOrg Org2MSP

    前提准备：
    1、生成组织结构及身份证书
    2、创建orderer的初始区块
    创建初始区块，是为了启动orderer服务（排序，生成区块）
    3、生成通道配置交易文件
    用来生成应用通道，指定通道内的成员及访问策略
    4、生成锚节点更新配置文件
    用来配置锚节点

    至此，启动网络的前提准备条件结束。

    启动网络

    $ sudo ./byfn.sh -m up

    如果启动发生错误,则执行关闭命令后再次执行启动命令

    最后输出如下内容代表启动且测试成功

    ============== Query on peer1.org2 on channel 'mychannel' is successful ================ 

========= All GOOD, BYFN execution completed ===========

    或者通过Node.js启动网络./byfn.sh -m up -l node

    first-network会生成1个orderer+4个peer+1个CLI的网络结构，整个网络包括2个org

    LOCAL_VERSION=1.1.0
DOCKER_IMAGE_VERSION=1.1.0
orderer.example.com is up-to-date
peer0.org2.example.com is up-to-date
peer1.org2.example.com is up-to-date
peer1.org1.example.com is up-to-date
peer0.org1.example.com is up-to-date

        -c:指定通道名称
        -f:指定之前生成的通道交易配置文件（已经指定好了有哪些组织）
        --tls:验证，是否使用tls协议，在数据传输过程中，保证数据的完整性
        --cafile:一旦启用了tls协议，就必须指定ca证书，docker容器中的证书文件
+ peer channel create -o orderer.example.com:7050 -c mychannel -f ./channel-artifacts/channel.tx --tls true --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem
启动网络：
    1、启动docker容器
    2、进入到容器中
    3、创建应用通道（利用之前生成的通道配置文件，拷贝到docker容器中，创建通道）
    4、将对应的节点加入到应用通道中
    5、更新锚节点（在开发阶段测试阶段暂时不需要，生产环境中需要执行这个）
创建通道成功：1，启动docker容器2、进入到容器里面创建通道
