fabric升级链码步骤

Fabric 2.2.1 升级链码步骤

1. 在通道所属的对等节点安装链码

peer lifecycle chaincode install 
    ${CC_NAME}.tar.gzs

2. 查询链码是否被安装

peer lifecycle chaincode queryinstalled

3. 机构1审批，检查链码定义是否准备好提交
   (1) 机构审批

peer lifecycle chaincode 
    approveformyorg 
    -o localhost:7050 
    --ordererTLSHostnameOverride orderer.example.com 
    --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}

(2) 检查链码是否准备好

peer lifecycle chaincode checkcommitreadiness 
    --channelID $CHANNEL_NAME 
    --name ${CC_NAME} 
    --version ${CC_VERSION} 
    --sequence ${CC_SEQUENCE} ${INIT_REQUIRED} ${CC_END_POLICY} ${CC_COLL_CONFIG} 
    --output json

4. 机构2审批，检查链码定义是否准备好提交
5. 提交链码定义

peer lifecycle chaincode commit 
    -o localhost:7050 
    --ordererTLSHostnameOverride orderer.example.com 
    --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}

验证升级成功
