接下来的操作都将在hyperledge环境安装构建的虚拟机的环境下进行

参考https://hyperledgercn.github.io/hyperledgerDocs/build_network_zh/

1》运行实例

先下载hyperledger fabric samples示例

vagrant@ubuntu-xenial:~$ git clone https://github.com/hyperledger/fabric-samples.git

然后进入其的first-network目录，因为下面要运行的目录都必须运行在这个目录下，否则提供的一些脚本可能无法找到对应的二进制：

vagrant@ubuntu-xenial:~$ ls

fabric-samples

vagrant@ubuntu-xenial:~$ cd fabric-samples/first-network/

vagrant@ubuntu-xenial:~/fabric-samples/first-network$ ls

base                docker-compose-cli.yaml           docker-compose-org3.yaml

byfn.sh             docker-compose-couch-org3.yaml    eyfn.sh

channel-artifacts   docker-compose-couch.yaml         org3-artifacts

configtx.yaml       docker-compose-e2e-template.yaml  README.md

crypto-config.yaml  docker-compose-kafka.yaml         scripts

在这个文档中提供一个完全注释的脚本byfn.sh，利用这些Docker镜像可以快速引导一个由4个代表2个不同组织的peer节点以及一个排序服务节点的Hyperledger fabric网络。它还将启动一个容器来运行一个将peer节点加入channel、部署实例化链码服务以及驱动已经部署的链码执行交易的脚本

首先我们能够使用命令./byfn.sh -h来查看脚本的帮助信息：

vagrant@ubuntu-xenial:~/fabric-samples/first-network$ ./byfn.sh -h

Usage:

  byfn.sh <mode> [-c <channel name>] [-t <timeout>] [-d <delay>] [-f <docker-compose-file>] [-s <dbtype>] [-l <language>] [-o <consensus-type>] [-i <imagetag>] [-v]

    <mode> - one of 'up', 'down', 'restart', 'generate' or 'upgrade'

      - '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 version 1.3.x to 1.4.0

    -c <channel name> - channel name to use (defaults to "mychannel")

    -t <timeout> - CLI timeout duration in seconds (defaults to 10)，即如果你选择不设置它，那么CLI容器将会在脚本执行完之后退出

    -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

    -o <consensus-type> - the consensus-type of the ordering service: solo (default) or kafka

    -i <imagetag> - the tag to be used to launch the network (defaults to "latest")

    -v - verbose mode

  byfn.sh -h (print this message)

一般来说，应该先生成需要的证书和创世区块，然后运行该网络，如：
（下面使用自定义的channel名，指明使用数据库couchdb，镜像标签为1.4.0，并声明使用node语言）

    byfn.sh generate -c mychannel

    byfn.sh up -c mychannel -s couchdb

        byfn.sh up -c mychannel -s couchdb -i 1.4.0

    byfn.sh up -l node

    byfn.sh down -c mychannel

        byfn.sh upgrade -c mychannel

当然，你也可以完全使用默认的配置：

    byfn.sh generate

    byfn.sh up

    byfn.sh down

1）generate

首先我们先将需要的证书和创世区块构建好,运行的过程中出现一个问题：

vagrant@ubuntu-xenial:~/fabric-samples/first-network$ ./byfn.sh generate

Generating certs and genesis block for channel 'mychannel' with CLI timeout of '' seconds and CLI delay of '' seconds

Continue? [Y/n] y

proceeding ...

cryptogen tool not found. exiting

需要知道什么是cryptogen，可见：hyperledge工具-cryptogen

运行该./byfn.sh generate命令会执行三个函数：

  • generateCerts ：先生成证书
  • replacePrivateKey ：然后使用docker-compose-e2e-template.yaml文件，用上面那一步使用cryptogen工具生成的私钥文件名来替换docker-compose-e2e-template.yaml文件中的常量，即CA1_PRIVATE_KEY和CA2_PRIVATE_KEY，并输出到特定于此配置的docker-compose-e2e.yaml文件中，来构建docker-compose-e2e.yaml文件
  • generateChannelArtifacts ：生成排序服务节点使用的创世区块、创建通道使用的通道配置交易以及更新通道用的锚节点交易

generateChannelArtifacts中使用了configtxgen工具，详情可见hyperledge工具-configtxgen

然后现在重新运行一次该命令：

Using docker-compose-e2e-template.yaml, replace constants with private key file names generated by the cryptogen tool and output a docker-compose.yaml specific to this configuration

vagrant@ubuntu-xenial:~/fabric-samples/first-network$ ls #一开始的文档情况

base                docker-compose-cli.yaml           docker-compose-org3.yaml

byfn.sh             docker-compose-couch-org3.yaml    eyfn.sh

channel-artifacts   docker-compose-couch.yaml         org3-artifacts

configtx.yaml       docker-compose-e2e-template.yaml  README.md

crypto-config.yaml  docker-compose-kafka.yaml         scripts

vagrant@ubuntu-xenial:~/fabric-samples/first-network$ ./byfn.sh generate #成功执行命令

Generating certs and genesis block for channel 'mychannel' with CLI timeout of '' seconds and CLI delay of '' seconds

Continue? [Y/n] y

proceeding ...

上面第一步生成我们各种网络实体的所有证书和密钥，genesis block用于引导排序服务，以及配置Channel所需要的一组交易配置集合。

2）up——启动程序

出现一个问题：

为了能够正确地在账本上进行读写操作，链码服务必须被安装在peer节点上。此外，每个peer节点的链码服务的容器除了init或者传统的交易-读/写-针对该链码服务执行（例如查询a的值），在其他情况下不会启动。

交易导致容器的启动。

当然，所有信道中的节点都持有以块的形式顺序存储的不可变的账本精确的备份，以及状态数据库来保存前状态的快照。这包括了没有在其上安装链码服务的peer节点（peer1.org2.example.com如上所示）。最后，链码在被安装后将是可达状态，因为它已经被实例化了。

此时使用docker查看容器状态:

3)查看日志

2》链码日志

4）使用的docker-compose

BYFN示例给我们提供了两种风格的Docker Compose文件，它们都继承自docker-compose-base.yaml

1》 docker-compose-cli.yaml

该文件提供了一个CLI容器，以及一个orderer容器，四个peer容器。我们用此文件来展开这个页面上的所有说明。

2》docker-compose-e2e.yaml

该文件被构造为使用Node.js SDK来运行端到端测试。除了SDK的功能之外，它主要的区别在于它有运行fabric-ca服务的容器。因此，我们能够向组织的CA节点发送REST的请求用于注册和登记。

如果你在没有运行byfn.sh脚本的情况下，想使用docker-compose-e2e.yaml，我们需要进行4个轻微的修改。因为

docker-compose-e2e.yaml是通过运行byfn.sh脚本在docker-compose-e2e-template.yaml文件的基础上生成的，需要将docker-compose-e2e-template.yaml文件中的CA1_PRIVATE_KEY和CA2_PRIVATE_KEY值进行手动更改为对应组织的私钥

我们需要指出本组织CA的私钥。你可以在crypto-config文件夹中找到这些值。举个例子，为了定位Org1的私钥，我们将使用crypto-config/peerOrganizations/org1.example.com/ca/。Org2的路径为crypto-config/peerOrganizations/org2.example.com/ca/，如下：

vagrant@ubuntu-xenial:~/fabric-samples/first-network/crypto-config/peerOrganizations/org1.example.com/ca$ ls

c46248ab640...1cca3c5f4c8dae571e5df2a77f57e3a48_sk  ca.org1.example.com-cert.pem

第一个文件夹的名字就是该组织的私钥值

5）使用CouchDB

没有试着使用这个，之后再补上

6）关于数据持久化的提示

如果需要在peer容器或者CouchDB容器进行数据持久化，一种选择是将docker容器内相应的目录挂载到容器所在的宿主机的一个目录中。例如，你可以添加下列的两行到docker-compose-base.yaml文件中peer的约定中：

volumes:

 - /var/hyperledger/peer0:/var/hyperledger/production

对于CouchDB容器，你可以在CouchDB的约定中添加两行：

volumes:

 - /var/hyperledger/couchdb0:/opt/couchdb/data
