簡介

以Hyperldger2.0為例，鏈碼的安裝主要分為以下幾部分：

package ：打包源代碼
install：安裝鏈碼
approveformyorg: 節點所在組織審批鏈碼
commit：提交鏈碼
在完成之后可以執行鏈碼的查詢和呼叫

package

首先需要對合約進行編譯，首先把我們寫的go語言合約放到chaincode下新建的test檔案夾下，

root@lamaxiya:/opt/gopath/src/github.com/hyperledger/fabric-samples/chaincode/test# pwd
/opt/gopath/src/github.com/hyperledger/fabric-samples/chaincode/test
root@lamaxiya:/opt/gopath/src/github.com/hyperledger/fabric-samples/chaincode/test# ls
CaAndFakeName.go
root@lamaxiya:/opt/gopath/src/github.com/hyperledger/fabric-samples/chaincode/test#

執行命令go mod init生成go.mod

root@lamaxiya:/opt/gopath/src/github.com/hyperledger/fabric-samples/chaincode/test# go mod init
go: creating new go.mod: module github.com/hyperledger/fabric-samples/chaincode/test
root@lamaxiya:/opt/gopath/src/github.com/hyperledger/fabric-samples/chaincode/test# ls
CaAndFakeName.go  go.mod

執行命令go run CaAndFakeName.go 生成go.sum

root@lamaxiya:/opt/gopath/src/github.com/hyperledger/fabric-samples/chaincode/test# go run CaAndFakeName.go 
Error starting UserCA chaincode: 'CORE_CHAINCODE_ID_NAME' must be setroot@lamaxiya:/opt/gopath/src/github.com/hyperledger/fabric-samples/chaincode/test# ls
CaAndFakeName.go  go.mod  go.sum

上述的CORE_CHAINCODE_ID_NAME不設定不影響鏈碼部署和執行，

執行命令GO111MODULE=on go mod vendor生成vendor包

root@lamaxiya:/opt/gopath/src/github.com/hyperledger/fabric-samples/chaincode/test# GO111MODULE=on go mod vendor
root@lamaxiya:/opt/gopath/src/github.com/hyperledger/fabric-samples/chaincode/test# ls
CaAndFakeName.go  go.mod  go.sum  vendor

將我們編譯好的智能合約打包到容器內，執行命令如下：

docker exec cli peer lifecycle chaincode package $1.tar.gz \
	--path github.com/hyperledger/fabric-samples/chaincode/$3 \
       	--label $1_$2

上述引數定義為（下面的引數與此相同）：

$1表示我們自定義的合約打包的名字如（mycc.tar.gz 則引數1為mycc），
$2代表我們鏈碼的版本開始時一般為1，后續如果需要升級合約可依次為2、3、4……，
$3代表我們鏈碼放的位置(對應上文編譯時為test檔案夾，則引數2為test)，

install

在完成打包后執行安裝命令（安裝到示例網路的兩個組織的節點上）如下：

節點1，msp組態檔、address、tls組態檔默認為peer0.org1不用添加

docker exec cli peer lifecycle chaincode install $1.tar.gz

節點2，因為時在cli容器執行需要添加指定的檔案路徑

docker exec \
	-e CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/users/Admin@org2.example.com/msp \
	-e CORE_PEER_ADDRESS=peer0.org2.example.com:9051 \
	-e CORE_PEER_LOCALMSPID="Org2MSP" \
	-e 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 \
	cli peer lifecycle chaincode install $1.tar.gz

上述安裝成功的話會輸出鏈碼的package_id如下：

3cd7767df34500f3d72faf7efd9774fbd72da4be0696b37\022\007mycc_1" > 
2022-01-04 14:13:44.443 UTC [cli.lifecycle.chaincode] submitInstallProposal -> INFO 002 Chaincode code package identifier: mycc_1:cb23fa9b0bace2c353cd7767df34500f3d72faf7efd9774fbd72da4be0696b37

此package identifier: mycc_1:cb23fa9b0bace2c353cd7767df34500f3d72faf7efd9774fbd72da4be0696b37我們下文需要使用.

approveformyorg

在完成安裝命令之后需要組織進行同意命令如下：

peer0.org1執行命令

docker exec cli peer lifecycle chaincode approveformyorg \
	--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 \
	--channelID mychannel --name $1 --version $2 \
	--init-required --sequence $2 --waitForEvent --package-id $4

peer0.org2執行命令

docker exec \
	-e CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/users/Admin@org2.example.com/msp \
	-e CORE_PEER_ADDRESS=peer0.org2.example.com:9051 \
	-e CORE_PEER_LOCALMSPID="Org2MSP" \
	-e 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 \
	cli peer lifecycle chaincode approveformyorg \
	--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 \
	--channelID $4 --name $3 --version $2 --init-required \
	--sequence $2 --waitForEvent --package-id $1

上述引數$4就是上文中生成的package identifier，

commit

在完成組織審批之后，需要執行鏈碼向orderer節點進行提交執行如下命令：

docker exec cli peer lifecycle chaincode commit -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 \
	--peerAddresses peer0.org1.example.com:7051 \
	--tlsRootCertFiles /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt \
	--peerAddresses peer0.org2.example.com:9051 \
	--tlsRootCertFiles /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt \
	--channelID $4 --name $3 --version $2 --sequence $2 --init-required

上述命令成功執行完輸出如下表明鏈碼安裝成功，

2022-01-04 14:20:56.239 UTC [cli.lifecycle.chaincode] setOrdererClient -> INFO 001 Retrieved channel (mychannel) orderer endpoint: orderer.example.com:7050

以上就是fabric2.0中安裝一個鏈碼的正常步驟，
下面是我封裝的安裝鏈碼的兩個sh檔案，可以簡化終端輸入

檔案1是對步驟package和install的命令封裝，

function help(){
        echo "para1-----package_name"
        echo "para2-----chaincode_id"
        echo "para3-----chaincode_dir"
}
if [ $1 == "help" -o $1 == "h" -o $1 == "-h" -o $1 == "-help" ]; then
        help
        exit 1
fi
if [ $# -ne 3 ]; then
        echo "You need to enter three para3"
        exit 1
fi
#打包
docker exec cli peer lifecycle chaincode package $1.tar.gz \
        --path github.com/hyperledger/fabric-samples/chaincode/$3 \
        --label $1_$2
if [ $? -ne 0 ]; then
        echo "package error"
        exit 1
fi
docker exec cli ls
docker exec cli peer lifecycle chaincode install $1.tar.gz
if [ $? -ne 0 ]; then
        echo "install on org1 error"
        exit 1
fi
echo "install on org1 successful"
docker exec \
        -e CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/users/Admin@org2.example.com/msp \
        -e CORE_PEER_ADDRESS=peer0.org2.example.com:9051 \
        -e CORE_PEER_LOCALMSPID="Org2MSP" \
        -e 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 \
        cli peer lifecycle chaincode install $1.tar.gz
if [ $? -ne 0 ]; then
        echo "install on org2 error"
        exit 1
fi

linux執行命令為如下：sh 檔案名.sh $1 $2 $3需要注意將輸出的package identifier使用變數記錄下來，檔案2需要使用此引數

檔案2是對步驟approveformyorg和commit的命令封裝，

function help(){
        echo "para1-----package_id"
        echo "para2-----chaincode_id"
        echo "para3-----chaincode_name"
        echo "para4-----channel_name"
}
if [ $1 == "help" -o $1 == "h" -o $1 == "-h" -o $1 == "-help" ]; then
        help
        exit 1
fi
docker exec cli peer lifecycle chaincode approveformyorg \
        --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 \
        --channelID $4 --name $3 --version $2 \
        --init-required --sequence $2 --waitForEvent --package-id $1
if [ $? -ne 0 ]; then
        echo "approve failed for org1"
        exit 1
fi
echo "approved on org1 successful "
docker exec \
        -e CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/users/Admin@org2.example.com/msp \
        -e CORE_PEER_ADDRESS=peer0.org2.example.com:9051 \
        -e CORE_PEER_LOCALMSPID="Org2MSP" \
        -e 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 \
        cli peer lifecycle chaincode approveformyorg \
        --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 \
        --channelID $4 --name $3 --version $2 --init-required \
        --sequence $2 --waitForEvent --package-id $1
if [ $? -ne 0 ]; then
        echo "approve failed for org2"
        exit 1
fi
echo "approced on org2 successful"
docker exec cli peer lifecycle chaincode commit -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 \
        --peerAddresses peer0.org1.example.com:7051 \
        --tlsRootCertFiles /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt \
        --peerAddresses peer0.org2.example.com:9051 \
        --tlsRootCertFiles /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt \
        --channelID $4 --name $3 --version $2 --sequence $2 --init-required
if [ $? -ne 0 ]; then
        echo "commit failed"
        exit 1
fi
echo "commit successful"

linux執行命令為如下sh 檔案名.sh 引數1 引數2 引數3 引數4 引數1為上文輸出的package identifier，
