2.Hyperledger Fabric1.4中手动部署first-network

参考链接：https://hyperledger-fabric.readthedocs.io/en/release-1.4/build_network.html

在上一篇文章通过 ./byfn.sh up 脚本自动执行了first-network，这里博主将参考byfn.sh脚本里的内容手动部署first-network，这也有助于我们更好地理解Fabric网络的部署流程。
该实例中包括一个命令行客户端，一个orderer排序节点，两个组织（Org1和Org2），其中每个组织包含两个peer节点。

准备工作

进入first-samples目录，若之前运行过first-network，将网络关闭

cd $GOPATH/src/github.com/hyperledger/fabric/scripts/fabric-samples/first-network
./byfn.sh down

检查bin目录内是否存在所需的工具：

ls ../bin

若出现如下结果，则无问题:

configtxgen    cryptogen  fabric-ca-client      idemixgen  peer
configtxlator  discover   get-docker-images.sh  orderer

生成MSP证书

使用cryptogen工具，根据crypto-config.yaml配置文件生成证书：

../bin/cryptogen generate --config=./crypto-config.yaml

执行成功后会出现如下的结果

org1.example.com
org2.example.com

同时当前目录中会生成crypto-config文件夹，文件夹中包括ordererOrganizations和peerOrganizations两个文件夹，其中包含了排序服务组织机构的证书和Peer节点的证书。
生成排序服务创世区块

export FABRIC_CFG_PATH=$PWD
../bin/configtxgen -profile TwoOrgsOrdererGenesis -channelID byfn-sys-channel -outputBlock ./channel-artifacts/genesis.block

命令执行结果：

2019-04-18 20:04:37.630 CST [common.tools.configtxgen] main -> INFO 001 Loading configuration

2019-04-18 20:04:37.685 CST [common.tools.configtxgen] doOutputBlock -> INFO 007 Writing genesis block

成功后将会在当前目录中生成channel-artifacts文件夹，并在该文件夹中生成排序服务创世区块genesis.block。

创建通道配置交易

export CHANNEL_NAME=mychannel
../bin/configtxgen -profile TwoOrgsChannel -outputCreateChannelTx ./channel-artifacts/channel.tx -channelID $CHANNEL_NAME

命令执行结果：

2019-04-18 20:05:07.770 CST [common.tools.configtxgen] main -> INFO 001 Loading configuration
2019-04-18 20:05:07.793 CST [common.tools.configtxgen.localconfig] Load -> INFO 002 Loaded configuration: /home/dwm/go/src/github.com/hyperledger/fabric/scripts/fabric-samples/first-network/configtx.yaml

2019-04-18 20:05:07.823 CST [common.tools.configtxgen] doOutputChannelCreateTx -> INFO 006 Writing new channel tx

执行成功后将在channel-artifacts文件夹中生成channel.tx文件。

在通道中定义锚节点

定义通道中Org1的锚节点

../bin/configtxgen -profile TwoOrgsChannel -outputAnchorPeersUpdate ./channel-artifacts/Org1MSPanchors.tx -channelID $CHANNEL_NAME -asOrg Org1MSP

定义通道中Org2的锚节点

../bin/configtxgen -profile TwoOrgsChannel -outputAnchorPeersUpdate ./channel-artifacts/Org2MSPanchors.tx -channelID $CHANNEL_NAME -asOrg Org2MSP

启动网络

docker-compose -f docker-compose-cli.yaml up -d

命令执行完成后可执行：

docker ps -a

可以查看到如下内容：

创建并加入通道

我们首先进入容器：

docker exec -it cli bash

此时CLI中对应的为peer0.org1.example.com的环境变量，查看docker-compose-cli.yaml文件，可以看到如下环境变量的值：

CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/users/[email protected]/msp
CORE_PEER_ADDRESS=peer0.org1.example.com:7051
CORE_PEER_LOCALMSPID="Org1MSP"
CORE_PEER_TLS_ROOTCERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt

创建通道

export CHANNEL_NAME=mychannel
peer channel create -o orderer.example.com:7050 -c $CHANNEL_NAME -f ./channel-artifacts/channel.tx --tls --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem

当出现如下结果时，通道创建成功：

2019-04-18 12:06:51.196 UTC [channelCmd] InitCmdFactory -> INFO 001 Endorser and orderer connections initialized
2019-04-18 12:06:51.282 UTC [cli.common] readBlock -> INFO 002 Received block: 0

此时将能在容器的当前目录中得到该通道的创世区块mychannel.block。

节点peer0.org1.example.com加入通道

由docker-compose-cli.yaml配置文件知CLI启动时对应为peer0.org1.example.com的环境变量，故只需执行

peer channel join -b mychannel.block

便可将节点peer0.org1.example.com加入通道中。

节点peer1.org1.example.com加入通道

在命令行中输入如下命令修改CLI中的环境变量，使之对应节点peer1.org1.example.com

CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/users/[email protected]/msp
CORE_PEER_ADDRESS=peer1.org1.example.com:7051
CORE_PEER_LOCALMSPID="Org1MSP"
CORE_PEER_TLS_ROOTCERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/peers/peer1.org1.example.com/tls/ca.crt

接着执行

peer channel join -b mychannel.block

将节点peer1.org1.example.com加入通道中。

节点peer0.org2.example.com加入通道

在命令行中输入如下命令修改CLI中的环境变量，使之对应节点peer0.org2.example.com

CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/users/[email protected]/msp
CORE_PEER_ADDRESS=peer0.org2.example.com:7051
CORE_PEER_LOCALMSPID="Org2MSP"
CORE_PEER_TLS_ROOTCERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt

接着执行

peer channel join -b mychannel.block

将节点peer0.org2.example.com加入通道中。

节点peer1.org2.example.com加入通道

在命令行中输入如下命令修改CLI中的环境变量，使之对应节点peer1.org2.example.com

CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/users/[email protected]/msp
CORE_PEER_ADDRESS=peer1.org2.example.com:7051
CORE_PEER_LOCALMSPID="Org2MSP"
CORE_PEER_TLS_ROOTCERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/peers/peer1.org2.example.com/tls/ca.crt

接着执行

peer channel join -b mychannel.block

将节点peer1.org2.example.com加入通道中。
至此实例中的4个peer节点均加入了通道中。

更新锚节点

定义org1的锚节点
设置环境变量：

CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/users/[email protected]/msp
CORE_PEER_ADDRESS=peer0.org1.example.com:7051
CORE_PEER_LOCALMSPID="Org1MSP"
CORE_PEER_TLS_ROOTCERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt

更新锚节点：

peer channel update -o orderer.example.com:7050 -c $CHANNEL_NAME -f ./channel-artifacts/Org1MSPanchors.tx --tls --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem

定义org2的锚节点
设置环境变量：

CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/users/[email protected]/msp
CORE_PEER_ADDRESS=peer0.org2.example.com:7051
CORE_PEER_LOCALMSPID="Org2MSP"
CORE_PEER_TLS_ROOTCERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt

更新锚节点：

peer channel update -o orderer.example.com:7050 -c $CHANNEL_NAME -f ./channel-artifacts/Org2MSPanchors.tx --tls --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem

安装链码

应用需要通过链码来和账本进行交互，因此应在每个需要执行和背书交易的peer节点上安装链码。该实例中安装的链码为fabric-samples/chaincode/chaincode_example02/go目录下的chaincode_example02.go

在节点peer0.org1.example.com上安装链码

设置环境变量：

CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/users/[email protected]/msp
CORE_PEER_ADDRESS=peer0.org1.example.com:7051
CORE_PEER_LOCALMSPID="Org1MSP"
CORE_PEER_TLS_ROOTCERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt

安装链码：

peer chaincode install -n mycc -v 1.0 -p github.com/chaincode/chaincode_example02/go/

在节点peer1.org1.example.com上安装链码

设置环境变量：

CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/users/[email protected]/msp
CORE_PEER_ADDRESS=peer1.org1.example.com:7051
CORE_PEER_LOCALMSPID="Org1MSP"
CORE_PEER_TLS_ROOTCERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/peers/peer1.org1.example.com/tls/ca.crt

安装链码：

peer chaincode install -n mycc -v 1.0 -p github.com/chaincode/chaincode_example02/go/

在节点peer0.org2.example.com上安装链码

设置环境变量：

CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/users/[email protected]/msp
CORE_PEER_ADDRESS=peer0.org2.example.com:7051
CORE_PEER_LOCALMSPID="Org2MSP"
CORE_PEER_TLS_ROOTCERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt

安装链码：

peer chaincode install -n mycc -v 1.0 -p github.com/chaincode/chaincode_example02/go/

在节点peer1.org2.example.com上安装链码

设置环境变量：

CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/users/[email protected]/msp
CORE_PEER_ADDRESS=peer1.org2.example.com:7051
CORE_PEER_LOCALMSPID="Org2MSP"
CORE_PEER_TLS_ROOTCERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/peers/peer1.org2.example.com/tls/ca.crt

安装链码：

peer chaincode install -n mycc -v 1.0 -p github.com/chaincode/chaincode_example02/go/

实例化链码

peer chaincode instantiate -o orderer.example.com:7050 --tls --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C $CHANNEL_NAME -n mycc -v 1.0 -c '{"Args":["init","a", "100", "b","200"]}' -P "OR ('Org1MSP.peer','Org2MSP.peer')"

查询

我们在实例化链码时也进行了初始化，即将a赋值为100，b赋值为200，可以通过下列命令对a的值进行查询：

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

此时得到的结果为：

100

将命令后面的参数由a改为b，可以对b的值进行查询。

调用

我们可以通过调用如下命令，将a的值转移10给b：

peer chaincode invoke -o orderer.example.com:7050 --tls --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C $CHANNEL_NAME -n mycc -c '{"Args":["invoke","a","b","10"]}'

结果为：

2019-04-18 12:11:37.781 UTC [chaincodeCmd] chaincodeInvokeOrQuery -> INFO 001 Chaincode invoke successful. result: status:200

此时再对a进行查询：

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

得到的结果为：

90

即链码调用成功。

在节点peer0.org1.example.com中查询链码

上述查询和调用链码均是在节点peer1.org2.example.com中进行的，我们将CLI中环境变量设置为与节点peer0.org1.example.com对应，然后再该进行中进行查询：

CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/users/[email protected]/msp
CORE_PEER_ADDRESS=peer0.org1.example.com:7051
CORE_PEER_LOCALMSPID="Org1MSP"
CORE_PEER_TLS_ROOTCERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt

执行查询命令

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

得到结果为：

90

则first-network手动部署完成。
