Hyperledger Fabric服务启动与链码测试

发布时间：2020-07-14 03:11:05 来源：网络 阅读：24764 作者：暗黑魔君 栏目：编程语言

目录

  1. 通过自动化脚本启动服务
  2. 通过手动方式启动服务
  3. 测试链码

一.通过自动化脚本启动服务

自动化脚本byfn.sh位于目录$HOME/hyfa/fabric-samples/first-network下，具体用途如下

$./byfn.sh -h //查看帮助说明
Usage: 
  byfn.sh <mode> [-c <channel name>] [-t <timeout>] [-d <delay>] [-f <docker-compose-file>] [-s <dbtype>] [-l <language>] [-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 1.1.x to 1.2.x
    -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")
    -v - verbose mode
  byfn.sh -h (print this message)

Typically, one would first generate the required certificates and 
genesis block, then bring up the network. e.g.:

        byfn.sh generate -c mychannel
        byfn.sh up -c mychannel -s couchdb
        byfn.sh up -c mychannel -s couchdb -i 1.2.x
        byfn.sh up -l node
        byfn.sh down -c mychannel
        byfn.sh upgrade -c mychannel

Taking all defaults:
        byfn.sh generate
        byfn.sh up
        byfn.sh down

1.生成组织结构及×××书

$ sudo ./byfn.sh generate

  • 生成组织结构及×××书(保存在当前目录的crypto-config目录)

    drwxr-xr-x 3 root root 4096 Jul 11 11:26 ordererOrganizations
    drwxr-xr-x 4 root root 4096 Jul 11 11:26 peerOrganizations

  • 生成Orderer创世区块文件(保存在当前目录的chanel-artifacts目录下)

    $HOME/hyfa/fabric-samples/first-network/channel-artifacts/genesis.block

  • 生成应用通道交易配置文件(保存在当前目录的chanel-artifacts目录下)

    $HOME/hyfa/fabric-samples/first-network/channel-artifacts/channel.tx

  • 组织中锚节点更新配置文件(保存在当前目录的chanel-artifacts目录下)
    --检测当前应用通道中新加入的节点
    --跨组织的数据交换

    Org1MSPanchors.tx
    Org2MSPanchors.tx

2.创建容器与通道

$sudo ./byfn.sh up
  • 创建相应的docker容器

6.关闭服务

$sudo ./byfn.sh down //通过down参数关闭服务
  • 同时删除所生成的组织结构及×××书目录
  • 同时删除所生成的chanel-artifacts/目录下的四个配置文件
  • 同时删除所有启动的docker容器以及对应的镜像文件

二.通过手动方式启动服务

在实际的应用场景下，我们会经常对某些配置进行个性化定制，以满足实际生产需求，所以，我们在本小节介绍如何通过手动方式启动对应的服务，并通过修改相关配置文件满足实际场景，手动步骤与自动化脚本基本一致。

1.生成组织结构及×××书

$ cd hyfa/fabric-samples/first-network/

为fabric网络生成指定拓扑结构的组织关系和×××书

$ sudo ../bin/cryptogen generate --config=./crypto-config.yaml

此命令依赖 crypto-config.yaml 配置文件

命令输出

org1.example.com
org2.example.com

证书和密钥（即MSP）将被输出到目录 first-network/crypto-config 的目录中 

drwxr-xr-x 3 root root 4096 Jul 11 00:31 ordererOrganizations
drwxr-xr-x 4 root root 4096 Jul 11 00:31 peerOrganizations
  • ordererOrganizations
    包括构成Orderer组织(1个Orderer节点)的身份信息

  • peerOrganizations
    所有的Peer节点组织(2个组织, 4个节点)的相关身份信息. 其中最关键的是MSP目录, 代表了实体的身份信息

    $ tree -L 6 crypto-config //通过tree命令查看目录树

Cryptogen 按照配置文件中指定的结构生成了对应的组织和密钥、证书文件

其中最关键的是各个资源下的msp 目录内容，存储了生成的代表MSP 身份的各种证书文件，一般包括：

  • admincerts ：管理员的×××书文件
  • cacerts ：信任的根证书文件
  • key store ：节点的签名私钥文件
  • signcerts ：节点的签名×××书文件
  • tlscacerts: TLS 连接用的证书
  • intermediatecerts （可选）：信任的中间证书
  • crls （可选）：证书撤销列表
  • config.yaml （可选）：记录OrganizationalUnitldentifiers 信息，包括根证书位置和ID信息

这些身份文件随后可以分发到对应的Orderer 节点和Peer 节点上，并放到对应的MSP路径下，用于签名使用。

2.创建创世区块并启动Orderer

指定使用 configtx.yaml 文件中定义的 TwoOrgsOrdererGenesis 模板, 生成Orderer服务系统通道的初始区块文件

$ sudo ../bin/configtxgen -profile TwoOrgsOrdererGenesis -outputBlock ./channel-artifacts/genesis.block

命令输出

3.生成应用通道交易配置文件

$ export CHANNEL_NAME=mychannel //设置临时变量

指定使用 configtx.yaml 配置文件中的 TwoOrgsChannel 模板, 来生成新建通道的配置交易文件, TwoOrgsChannel 模板指定了Org1和Org2都属于后面新建的应用通道

$ sudo ../bin/configtxgen -profile TwoOrgsChannel -outputCreateChannelTx ./channel-artifacts/channel.tx -channelID $CHANNEL_NAME

-rw-r--r-- 1 root root 346 Jul 11 00:54 channel-artifacts/channel.tx //生成的通道文件

4.生成各组织的锚节点更新文件

锚节点配置更新文件用来对组织的锚节点进行配置

同样基于 configtx.yaml 配置文件生成新建通道文件, 每个组织都需要分别生成且注意指定对应的组织名称

$ sudo ../bin/configtxgen -profile TwoOrgsChannel -outputAnchorPeersUpdate ./channel-artifacts/Org1MSPanchors.tx -channelID $CHANNEL_NAME -asOrg Org1MSP

$ sudo ../bin/configtxgen -profile TwoOrgsChannel -outputAnchorPeersUpdate ./channel-artifacts/Org2MSPanchors.tx -channelID $CHANNEL_NAME -asOrg Org2MSP

5.创建容器，启动网络

$ sudo docker-compose -f docker-compose-cli.yaml up -d

-f: 指定docker-compose文件

-d：Detached mode,后台运行容器

命令输出

peer1.org1.example.com
peer0.org2.example.com
peer0.org1.example.com
orderer.example.com

6.创建通道并配置

执行如下命令进入到CLI容器中(后继操作都在容器中执行)

$ sudo docker exec -it cli bash

直接进入容器该路径下,相关操作不要更换路径

root@138a8115a08c:/opt/gopath/src/github.com/hyperledger/fabric/peer# pwd
/opt/gopath/src/github.com/hyperledger/fabric/peer

6.1 配置变量

export CHANNEL_NAME=mychannel

6.2 创建通道

$ peer channel create -o orderer.example.com:7050 -c $CHANNEL_NAME -f ./channel-artifacts/channel.tx --tls --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem

命令返回:

2018-07-11 11:44:50.198 UTC [channelCmd] InitCmdFactory -> INFO 001 Endorser and orderer connections initialized
2018-07-11 11:44:50.228 UTC [cli/common] readBlock -> INFO 002 Got status: &{NOT_FOUND}

6.3 当前节点加入通道

应用通道所包含组织的成员节点可以加入通道中

$ peer channel join -b mychannel.block

join命令: 将本Peer节点加入到某个应用通道中

命令返回

2018-07-11 13:20:01.980 UTC [channelCmd] InitCmdFactory -> INFO 001 Endorser and orderer connections initialized
2018-07-11 13:20:02.084 UTC [channelCmd] executeJoin -> INFO 002 Successfully submitted proposal to join channel

查看加入列表

$ peer channel list
Channels peers has joined: 
mychannel

6.4更新锚节点

锚节点通过广播的方式通知有新节点加入

  • 使用Org1的管理员身份更新锚节点配置(默认)

    $ peer channel update -o orderer.example.com:7050 -c $CHANNEL_NAME -f ./channel-artifacts/Org1MSPanchors.tx --tls --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem

命令返回

2018-07-11 12:00:12.677 UTC [channelCmd] InitCmdFactory -> INFO 001 Endorser and orderer connections initialized
2018-07-11 12:00:12.690 UTC [channelCmd] update -> INFO 002 Successfully submitted channel update
  • 使用Org2的管理员身份更新锚节点配置

变更脚本变量(比如当前变量CORE_PEER_LOCALMSPID默认为Org1MSP)

CORE_PEER_LOCALMSPID="Org2MSP"
CORE_PEER_ADDRESS=peer0.org2.example.com:7051 
CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/users/Admin@org2.example.com/msp
CORE_PEER_TLS_ROOTCERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt

执行更新锚节点配置命令

$ peer channel update -o orderer.example.com:7050 -c $CHANNEL_NAME -f ./channel-artifacts/Org2MSPanchors.tx --tls --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem

命令返回

2018-07-11 12:05:37.325 UTC [channelCmd] InitCmdFactory -> INFO 001 Endorser and orderer connections initialized
2018-07-11 12:05:37.338 UTC [channelCmd] update -> INFO 002 Successfully submitted channel update

如果需要加入其它组织，变更脚本变量后执行更新锚节点操作即可，至此，手动配置网络完成, 可以测试链码ChainCode

切换：pee1.org1.example.com

CORE_PEER_LOCALMSPID="Org1MSP"
CORE_PEER_ADDRESS=peer1.org1.example.com:7051 
CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabri c/peer/crypto/peerOrganizations/org1.example.com/users/Admin@org1.exa mple.com/msp 
CORE_PEER_TLS_ROOTCERT_FILE=/opt/gopath/src/github.com/hyperledger/fa bric/peer/crypto/peerOrganizations/org1.example.com/peers/peer1.org1.exa mple.com/tls/ca.crt

三.测试链码

进去CLI容器进行相关运维操作

$ sudo docker exec -it cli bash

Peer加入应用通道后, 可以执行链码相关操作,进行测试 链码在调用之前, 必须先经过安装和实例化两个步骤, 部署到Peer节点上.

1.查看并环境变量

$ echo $CORE_PEER_LOCALMSPID #确认当前指定的org
Org1MSP
$ echo $CORE_PEER_ADDRESS  #确认当前指定的peer
peer0.org1.example.com:7051
$ export CHANNEL_NAME=mychannel #设置通道名称

2.安装并实例化链码

2.1 链码使用须知

-- 将其安装在指定的节点上

-- 安装完成后要对其进行实例化

-- 调用链码(查询, 执行事务)

2.2 安装并实例化链码
