1.環(huán)境準(zhǔn)備

進(jìn)入test-network目錄下，使用which peer 檢查一下環(huán)境是否有問題

如果有問題就下面指令配置一下（后面的路徑根據(jù)自己的fabric-sample路徑確定）

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

使用 echo $FABRIC_CFG_PATH 查看是否輸入相關(guān)路徑，否則輸入指令

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

可以啟動(dòng)兩個(gè)回話模擬兩個(gè)組織 org1 和 org2 ，在兩個(gè)會(huì)話中分別輸入下面的指令以配置環(huán)境

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

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

然后使用peer channel list指令查看目前通道情況

報(bào)錯(cuò)情況：

ubuntu@VM-16-12-ubuntu:~/go/src/github.com/hyperledger/fabric-samples/test-network$ peer channel list

2022-12-06 21:07:20.412 CST 0001 ERRO [main] InitCmd -> Cannot run peer because cannot init crypto, specified path "/home/ubuntu/go/src/github.com/hyperledger/fabric-samples/config/msp" does not exist or cannot be accessed: stat /home/ubuntu/go/src/github.com/hyperledger/fabric-samples/config/msp: no such file or directory

原因是因?yàn)闆]有配置環(huán)境變量來使用org1或者org2來進(jìn)行交互

2. erc20部署

2.1 打包鏈碼

在打包鏈碼之前先檢查一下erc20鏈碼所在的目錄中是否包含vendor，如果沒有的話依舊是手動(dòng)拉取

ls ../token-erc-20/chaincode-go/

我這里沒有，所以需要執(zhí)行下面命令手動(dòng)拉取

cd ../token-erc-20/chaincode-go/

go mod vendor

然后再回到test-network目錄下打包鏈碼(org1)

peer lifecycle chaincode package erc20.tar.gz --path ../token-erc-20/chaincode-go/ --lang golang --label erc20_1.0 

2.2 安裝鏈碼(1&2)

peer lifecycle chaincode install erc20.tar.gz

查看鏈碼安裝情況

peer lifecycle chaincode queryinstalled

設(shè)置環(huán)境變量（org1+org2）

export ERC20_ID=erc20_1.0:7c99f9616d100b2736ad1d03850e24b844e0d5d1af433b8ab673ba934acf8e8c

approve（org1+org2）

peer lifecycle chaincode approveformyorg -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --channelID mychannel --name erc20 --version 1.0 --package-id $ERC20_ID --sequence 1 --tls --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem

可以檢查一下是否可以commit

peer lifecycle chaincode checkcommitreadiness --channelID mychannel --name erc20 --version 1.0 --sequence 1 --tls --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem

commit（org1/org2）

peer lifecycle chaincode commit -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --channelID mychannel --name erc20 --version 1.0 --sequence 1 --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

2.3 測(cè)試erc20

mint測(cè)試(只有org1可以執(zhí)?) mint相當(dāng)于初始化最初的資源數(shù)量 類似于發(fā)行貨幣

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 -C mychannel -n erc20 --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 '{"function":"Mint","Args":["900"]}'
