一、修改链码，上传

二、打包链码

1、设置组织1环境变量

export PATH=${PWD}/../bin:$PATH
export FABRIC_CFG_PATH=$PWD/../config/
# Environment variables for Org1
export CORE_PEER_TLS_ENABLED=true
export CORE_PEER_LOCALMSPID="Org1MSP"
export CORE_PEER_TLS_ROOTCERT_FILE=${PWD}/organizations/peerOrganizations/org1.sdmk.com.cn/peers/peer0.org1.sdmk.com.cn/tls/ca.crt
export CORE_PEER_MSPCONFIGPATH=${PWD}/organizations/peerOrganizations/org1.sdmk.com.cn/users/Admin@org1.sdmk.com.cn/msp
export CORE_PEER_ADDRESS=localhost:7051

2、重新打包链码

peer lifecycle chaincode package sdmkmeterchannel.tar.gz --path ./meter-chaincode/chaincode-go/ --lang golang --label sdmkmeterchannel_2.0 #安装
peer lifecycle chaincode install sdmkmeterchannel.tar.gz#查询已安装链码
peer lifecycle chaincode queryinstalled

 组织2也安装，先设置组织2环境变量

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

peer lifecycle chaincode install sdmkmeterchannel.tar.gz
peer lifecycle chaincode queryinstalled

设置PACKAGE_ID

export PACKAGE_ID=s

 3、设置所需要的环境变量

export CORE_PEER_TLS_ENABLED=true
export ORDERER_CA=${PWD}/organizations/ordererOrganizations/sdmk.com.cn/orderers/orderer.sdmk.com.cn/msp/tlscacerts/tlsca.sdmk.com.cn-cert.pem
export PEER0_ORG1_CA=${PWD}/organizations/peerOrganizations/org1.sdmk.com.cn/peers/peer0.org1.sdmk.com.cn/tls/ca.crt
export PEER0_ORG2_CA=${PWD}/organizations/peerOrganizations/org2.sdmk.com.cn/peers/peer0.org2.sdmk.com.cn/tls/ca.crt
export ORDERER_ADMIN_TLS_SIGN_CERT=${PWD}/organizations/ordererOrganizations/sdmk.com.cn/orderers/orderer.sdmk.com.cn/tls/server.crt
export ORDERER_ADMIN_TLS_PRIVATE_KEY=${PWD}/organizations/ordererOrganizations/sdmk.com.cn/orderers/orderer.sdmk.com.cn/tls/server.keyexport CHANNEL_NAME="sdmkmeterchannel"
export CC_NAME=sdmkmeterbasic
export CC_SRC_PATH=./meter-chaincode/chaincode-go/
export CC_SRC_LANGUAGE=go
export CC_VERSION="2.0"
export CC_SEQUENCE="2"
export CC_INIT_FCN=""
export CC_END_POLICY=""
export CC_COLL_CONFIG=""
export DELAY="3"
export MAX_RETRY="5"
export VERBOSE="false"
export INIT_REQUIRED=""
export CC_RUNTIME_LANGUAGE=golang

4、重新同意链码定义

目前还是组织机构2环境变量

peer lifecycle chaincode approveformyorg -o localhost:7050 --ordererTLSHostnameOverride orderer.sdmk.com.cn --tls --cafile "$ORDERER_CA" --channelID $CHANNEL_NAME --name ${CC_NAME} --version ${CC_VERSION} --package-id ${PACKAGE_ID} --sequence ${CC_SEQUENCE} ${INIT_REQUIRED} ${CC_END_POLICY} ${CC_COLL_CONFIG} ##查询当前链码定义已同意的组织
peer lifecycle chaincode checkcommitreadiness --name ${CC_NAME}  --channelID $CHANNEL_NAME  --version ${CC_VERSION} --sequence ${CC_SEQUENCE} ${INIT_REQUIRED} ${CC_END_POLICY} ${CC_COLL_CONFIG} --output json

 

 切换组织1环境变量

export PATH=${PWD}/../bin:$PATH
export FABRIC_CFG_PATH=$PWD/../config/
# Environment variables for Org1
export CORE_PEER_TLS_ENABLED=true
export CORE_PEER_LOCALMSPID="Org1MSP"
export CORE_PEER_TLS_ROOTCERT_FILE=${PWD}/organizations/peerOrganizations/org1.sdmk.com.cn/peers/peer0.org1.sdmk.com.cn/tls/ca.crt
export CORE_PEER_MSPCONFIGPATH=${PWD}/organizations/peerOrganizations/org1.sdmk.com.cn/users/Admin@org1.sdmk.com.cn/msp
export CORE_PEER_ADDRESS=localhost:7051

peer lifecycle chaincode approveformyorg -o localhost:7050 --ordererTLSHostnameOverride orderer.sdmk.com.cn --tls --cafile "$ORDERER_CA" --channelID $CHANNEL_NAME --name ${CC_NAME} --version ${CC_VERSION} --package-id ${PACKAGE_ID} --sequence ${CC_SEQUENCE} ${INIT_REQUIRED} ${CC_END_POLICY} ${CC_COLL_CONFIG} ##查询当前链码定义已同意的组织
peer lifecycle chaincode checkcommitreadiness --name ${CC_NAME}  --channelID $CHANNEL_NAME  --version ${CC_VERSION} --sequence ${CC_SEQUENCE} ${INIT_REQUIRED} ${CC_END_POLICY} ${CC_COLL_CONFIG} --output json

 结果显示，组织1，组织2都已经显示

5、重新提交链码定义

export PEER_CONN_PARMS=(--peerAddresses localhost:7051 --tlsRootCertFiles ${PWD}/organizations/peerOrganizations/org1.sdmk.com.cn/peers/peer0.org1.sdmk.com.cn/tls/ca.crt --peerAddresses localhost:9051 --tlsRootCertFiles ${PWD}/organizations/peerOrganizations/org2.sdmk.com.cn/peers/peer0.org2.sdmk.com.cn/tls/ca.crt)peer lifecycle chaincode commit -o localhost:7050 --ordererTLSHostnameOverride orderer.sdmk.com.cn --tls --cafile "$ORDERER_CA" --channelID $CHANNEL_NAME --name ${CC_NAME} "${PEER_CONN_PARMS[@]}" --version ${CC_VERSION} --sequence ${CC_SEQUENCE} ${INIT_REQUIRED} ${CC_END_POLICY} ${CC_COLL_CONFIG} 

 6、查询提交定义的结果

peer lifecycle chaincode querycommitted  --channelID $CHANNEL_NAME --name ${CC_NAME}

 恭喜你，链码升级成功
