(二)熟悉fabric并查看测试test-network

骑在牛背上看书 2022-03-11 阅读 33
fabric运维

首先在~/go/src/github.com/hyperledger/fabric下进行orderer和peer的编译

编译Orderer

$ cd $GOPATH/src/github.com/hyperledger/fabric/

$ make orderer

命令执行后终端输出如下：

编译peer

$ make peer

命令执行后终端输出如下：

编译生成相关工具

Hyperledger Fabric 除了 Orderer 和 Peer 之外，还为我们提供了在搭建网络环境时所需要的一系列辅助工具：

  • configtxgen：生成初始区块及通道交易配置文件的工具
  • cryptogen：生成组织结构及相应的的身份文件的工具
  • configtxlator：将指定的文件在二进制格式与JSON格式之间进行转换

编译生成这些工具同样使用 make 即可：

$ make configtxgen 
$ make cryptogen 
$ make configtxlator

 

查看 .build/bin 目录

$ ll build/bin/

测试fabric-samples/test-network这个测试例子

首先我们启动这个测试例子

cd fabric-samples/test-network

然后先移除先前运行中的所有容器

sudo ./network.sh down

然后重新打开容器

sudo ./network.sh up

可以通过命令来查看是否已经打开：

sudo docker ps -a

我们可以仔细看一下上面命令后得到的结果：

创建channel

Channel是一个用于特定网络成员之间通信的私有层，只有被邀请加入Channel的成员才能够使用它，对网络中其他成员不可见，每个Channel都有一个单独的区块链账本，被邀请加入Channel的peer可以存储Channel的账本然后验证Channel的交易。

运行如下命令可以创建一个名为mychannel的Channel连接Org1和Org2。

sudo ./network.sh createChannel

 为用户添加一个权限

sudo chmod -R 777 ~/go

同时由于还需要给用户添加opt的权限

sudo chmod -R 777 /opt

我们还需要设置go的环境

go env -w GO111MODULE=on
go env -w GOPROXY=https://goproxy.cn,direc

这样的话就可以进行链码的部署，注意这里不能用sudo 

./network.sh deployCC -ccn basic -ccp ../asset-transfer-basic/chaincode-go -ccl go

若出现这样的情况，说明链码部署成功 

xzd@xzd-virtual-machine:~/go/src/github.com/hyperledger/fabric/scripts/fabric-samples/test-network$ ./network.sh deployCC -ccn basic -ccp ../asset-transfer-basic/chaincode-go -ccl go

与网络进行交互:

当测试网络成功启动之后，可以利用命令行的peer命令与网络交互，它允许用户调用部署好的智能合约，更新channel或者安装和部署新的智能合约。

首先要设置一下，在bin目录下有peer等二进制文件，在config目录下有若干yaml文件，如果需要的话，可以使用如下命令将peer等添加到环境变量中：

export PATH=<path to download location>/bin:$PATH

我的地址是:

export PATH=~/go/src/github.com/hyperledger/fabric/scripts/fabric-samples/bin:$PATH

设置了环境变量之后，前往test-network文件夹中

先保证你要在test-network中：配置临时变量：

export PATH=${PWD}/../bin:$PATH

此外还需要配置一下config所在的目录。

export FABRIC_CFG_PATH=$PWD/../config/

设置如下的环境变量，可以使得你作为Org1来操作peer命令。

# Environment variables for Org1

export CORE_PEER_TLS_ENABLED=true
export CORE_PEER_LOCALMSPID="Org1MSP"
export CORE_PEER_TLS_ROOTCERT_FILE=${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt
export CORE_PEER_MSPCONFIGPATH=${PWD}/organizations/peerOrganizations/org1.example.com/users/Admin@org1.example.com/msp
export CORE_PEER_ADDRESS=localhost:7051

也可以作为Org2来操作peer命令，任选一个即可！我这里选择org1，这一段后面会用到暂时不用添加！！

# Environment variables for Org2
export CORE_PEER_TLS_ENABLED=true
export CORE_PEER_LOCALMSPID="Org2MSP"
export CORE_PEER_TLS_ROOTCERT_FILE=${PWD}/organizations/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt
export CORE_PEER_MSPCONFIGPATH=${PWD}/organizations/peerOrganizations/org2.example.com/users/Admin@org2.example.com/msp
export CORE_PEER_ADDRESS=localhost:9051

 CORE_PEER_TLS_ROOTCERT_FILE和CORE_PEER_MSPCONFIGPATH两行指明了Org1的加密所用的信息。

可以使用如下的命令来查看channel的账本中的汽车列表，这个列表是刚才使用deployCC参数时添加的。

查看fabcar链码：

peer chaincode query -C mychannel -n fabcar -c '{"Args":["queryAllCars"]}'

调用fabcar链码：

peer chaincode invoke \
-o localhost:7050 \
--ordererTLSHostnameOverride orderer.example.com \
--tls --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem \
--peerAddresses localhost:7051 \
--tlsRootCertFiles ${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt \
--peerAddresses localhost:9051 \
--tlsRootCertFiles ${PWD}/organizations/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt \
-C mychannel \
-n fabcar \
-c '{"function":"InitLedger","Args":[]}'

 出现"Chaincode invoke successful. result: status:200 "的字样，更新成功！

之后我们用org2来执行peer命令进行查询：

# Environment variables for Org2

export CORE_PEER_TLS_ENABLED=true
export CORE_PEER_LOCALMSPID="Org2MSP"
export CORE_PEER_TLS_ROOTCERT_FILE=${PWD}/organizations/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt
export CORE_PEER_MSPCONFIGPATH=${PWD}/organizations/peerOrganizations/org2.example.com/users/Admin@org2.example.com/msp
export CORE_PEER_ADDRESS=localhost:9051

然后可以使用如下命令来查看CAR9在账本中的情况。

peer chaincode query -C mychannel -n fabcar -c '{"Args":["queryCar","CAR9"]}'

 可以看到车辆已经被转移给了Dave，即刚才的更新成功了。

关闭网络

当使用完测试网络的时候，可以用如下命令来关闭测试网络。

./network.sh down

这条命令会停止并移走节点和chaincode的容器，删除加密所用的信息，并且移走channel和docker卷等之前运行产生的东西，不过如果需要的话，之后可以利用up参数再次让网络运行。

启动过程详解：（转载）

  • ./network.sh为两个peer节点和一个order节点创建了证书和密钥，默认情况下，脚本会利用在organizations/cryptogen文件夹下的加密工具。
  • 脚本利用configtxgen工具创建了系统的创世块，它使用configtx/configtx.yaml文件来创建创世块，并存储在system-genesis-block文件夹中。
  • 当上述两步完成之后，./network.sh会启动网络，脚本利用在docker文件夹下的docker-compose-test-net.yaml文件创建peer和orderer节点。
  • 如果使用了createChannel子命令，脚本还会运行script文件夹下的createChannel.sh脚本来创建所需要的channel，脚本会用peer命令来创建channel，加入两个组织。
  • 如果运行了deployCC命令，脚本会在所有peers上运行script下的deployCC.sh脚本来安装fabcar chaincode，在chaincode的定义被提交到channel之后，peer命令会调用init函数来初始化chaincode，并将所需的数据放入chaincode中。
