【三】启动网络流程以及相关命令

一、流程总览

启动脚本在firest-network下的script/script.sh，utils.sh脚本中

## Create channel
echo "Creating channel..."
createChannel

## Join all the peers to the channel
echo "Having all peers join the channel..."
joinChannel

## Set the anchor peers for each org in the channel
echo "Updating anchor peers for org1..."
updateAnchorPeers 0 1
echo "Updating anchor peers for org2..."
updateAnchorPeers 0 2

## Install chaincode on peer0.org1 and peer0.org2
echo "Installing chaincode on peer0.org1..."
installChaincode 0 1
echo "Install chaincode on peer0.org2..."
installChaincode 0 2

# Instantiate chaincode on peer0.org2
echo "Instantiating chaincode on peer0.org2..."
instantiateChaincode 0 2
# Query chaincode on peer0.org1
echo "Querying chaincode on peer0.org1..."
chaincodeQuery 0 1 100


# Invoke chaincode on peer0.org1
echo "Sending invoke transaction on peer0.org1..."
chaincodeInvoke 0 1


## Install chaincode on peer1.org2
echo "Installing chaincode on peer1.org2..."
installChaincode 1 2


# Query on chaincode on peer1.org2, check if the result is 90
echo "Querying chaincode on peer1.org2..."
chaincodeQuery 1 2 90

从以上流程中可以看出，分为几个步骤进行启动：

1、创建通道

peer channel create -o orderer.example.com:7050 -c $CHANNEL_NAME -f ./channel-artifacts/channel.tx

2、加入通道

将前面生产的block，以及相关的peer和org加入到通道中，

peer channel join -b $CHANNEL_NAME.block  >&log.txt

3、更新钩子

参数是org和peer名

peer channel update -o orderer.example.com:7050 -c $CHANNEL_NAME -f ./channel-artifacts/${CORE_PEER_LOCALMSPID}anchors.tx >&log.txt

4、安装智能合约

参数是org和peer名

peer chaincode install -n mycc -v ${VERSION} -l ${LANGUAGE} -p ${CC_SRC_PATH} >&log.txt

5、实体化智能合约

peer chaincode instantiate -o orderer.example.com:7050 -C $CHANNEL_NAME -n mycc -l ${LANGUAGE} -v ${VERSION} -c '{"Args":["init","a","100","b","200"]}' -P "OR  ('Org1MSP.peer','Org2MSP.peer')" >&log.txt

6、对数据进行查询

peer chaincode query -C $CHANNEL_NAME -n mycc -c '{"Args":["query","a"]}' >&log.txt

7、对数据进行增删改

peer chaincode invoke -o orderer.example.com:7050 -C $CHANNEL_NAME -n mycc -c '{"Args":["invoke","a","b","10"]}' >&log.txt
