### docker 安裝 如果服務器上有舊版的docker，需要先執行卸載操作。 $ sudo yum remove docker \ docker-common \ docker-selinux \ docker-engine 隨后開始安裝docker-ce 1 $ sudo yum install -y yum-utils device-mapper-persistent-data lvm2 2 3 $ sudo yum-config-manager \ 4 --add-repo \ 5 https://download.docker.com/linux/centos/docker-ce.repo 6 7 $ sudo yum-config-manager --enable docker-ce-edge 8 9 $ sudo yum-config-manager --enable docker-ce-test 10 11 $ sudo yum-config-manager --disable docker-ce-edge 12 13 $ sudo yum makecache fast 14 15 $ sudo yum install docker-ce 執行查詢docker版本號，看是否安裝成功 docker --version docker啟動 service docker start docker開機自啟（視具體情況使用） chkconfig docker on ### docker-compose 安裝 需要服務器支持 curl 功能，如果服務器不支持 curl 功能，需要手動進行安裝 yum install curl 執行如下操作下載docker-compose sudo curl -L "https://github.com/docker/compose/releases/download/1.26.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose 下載目錄為： /usr/local/bin/docker-compose 為其添加可執行權限： sudo chmod +x /usr/local/bin/docker-compose 查詢版本信息： docker-compose --version ### Go語言安裝 安裝包下載 curl -O https://golang.google.cn/doc/install?download=go1.15.linux-amd64.tar.gz 解壓縮文件包 tar -C /usr/local -xzf go1.15.linux-amd64.tar.gz 配置 go 的環境變量 修改 /etc/profile 文件使其永久生效 1 export PATH=$PATH:/usr/local/go/bin 2 export GOPATH=/opt/gopath 修改文件后，執行如下命令，應用上述參數 source /etc/profile 查看當前 go 版本信息 go version 也可通過下述命令查看是否安裝成功 echo $PATH
下載 fabric 源碼是因為要用到源碼中的例子和工具，工具編譯需要用到 go 語言環境，因此需要把源碼目錄放到 GOPATH 下，路徑設置為 /opt/gopath 可以使用 Git 命令下載源碼（耗時會比較長）： cd /opt/gopath/src/github.com/hyperledger/ git clone https://github.com/hyperledger/fabric.git 如果沒有 git 命令，需要先執行如下命令，構建 git 環境： yum install git 默認Fabric源碼下載版本為 2.2.0 Fabric Docker 鏡像的下載： cd /opt/gopath/src/github.com/hyperledger/fabric/scripts ./bootstrap.sh 等待下載完成即可 至此，Fabric源碼，fabric-samples 源碼、fabric 鏡像的工作已經完成
啟動 Fabric 網絡 cd /opt/gopath/src/github.com/hyperledger/fabric/scripts/fabric-samples/test-network ./network.sh up 建立通道 ./network.sh createChannel 在通道上啟動鏈碼 ./network.sh deployCC 如果鏈碼啟動失敗，手動添加 go 代理 go env -w GO111MODULE=on go env -w GOPROXY=https://goproxy.cn,direct 再次啟動鏈碼即可 在test-network 目錄進行如下環境變量設置 export PATH=${PWD}/../bin:${PWD}:$PATH export FABRIC_CFG_PATH=$PWD/../config/ 繼續設置如下環境變量，允許以 peer Org1 的形式操作 CLI # Environment variables for Org1 export CORE_PEER_TLS_ENABLED=true export CORE_PEER_LOCALMSPID="Org1MSP" export CORE_PEER_TLS_ROOTCERT_FILE=${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt export CORE_PEER_MSPCONFIGPATH=${PWD}/organizations/peerOrganizations/org1.example.com/users/Admin@org1.example.com/msp export CORE_PEER_ADDRESS=localhost:7051 完成后，source /etc/profile 獲取已添加到通道分類賬中的汽車列表 peer chaincode query -C mychannel -n fabcar -c '{"Args":["queryAllCars"]}' 上述命令可能會出現報錯提示，如下（如果是提示某些文件不存在，我的一個解決辦法是，關閉網絡，啟動網絡前，source /etc/profile）： Error: endorsement failure during query. response: status:500 message:"make sure the chaincode fabcar has been successfully defined on channel mychannel and try again: chaincode fabcar not found" 查看報錯信息，我們可以知道，鏈碼 fabcar 沒有在通道上被定義，所以我們進入對應目錄，執行啟動指令： cd /opt/gopath/src/github.com/hyperledger/fabric/scripts/fabric-samples/fabcar ./startFabric.sh 等待執行結束即可 我們現在可以重新進入 test-network 目錄，執行命令 peer chaincode query -C mychannel -n fabcar -c '{"Args":["queryAllCars"]}' 可以看到，正常返回結果了 [{"Key":"CAR0","Record":{"make":"Toyota","model":"Prius","colour":"blue","owner":"Tomoko"}},{"Key":"CAR1","Record":{"make":"Ford","model":"Mustang","colour":"red","owner":"Brad"}},{"Key":"CAR2","Record":{"make":"Hyundai","model":"Tucson","colour":"green","owner":"Jin Soo"}},{"Key":"CAR3","Record":{"make":"Volkswagen","model":"Passat","colour":"yellow","owner":"Max"}},{"Key":"CAR4","Record":{"make":"Tesla","model":"S","colour":"black","owner":"Adriana"}},{"Key":"CAR5","Record":{"make":"Peugeot","model":"205","colour":"purple","owner":"Michel"}},{"Key":"CAR6","Record":{"make":"Chery","model":"S22L","colour":"white","owner":"Aarav"}},{"Key":"CAR7","Record":{"make":"Fiat","model":"Punto","colour":"violet","owner":"Pari"}},{"Key":"CAR8","Record":{"make":"Tata","model":"Nano","colour":"indigo","owner":"Valeria"}},{"Key":"CAR9","Record":{"make":"Holden","model":"Barina","colour":"brown","owner":"Shotaro"}}]
上述調試工作相繼完成后，我們繼續如下操作（仍然在 test-network 目錄下），執行關閉網絡指令：
./network.sh down
接着，編輯profile文件，添加如下內容（因為資產轉移鏈碼的背書策略要求事務由 Org1 和 Org2 簽名，chaincode invoke 命令需要同時針對 peer0.org1.example.com 和 peer0.org2.example.com 使用 --peeradresses 標志，而且，由於為網絡啟用了 TLS， 該命令還需要使用 --tlsRootCertFiles 標志為每個對等方引用 TLS 證書。）：
vi /etc/profile
# Environment variables for Org2
export CORE_PEER_TLS_ENABLED=true
export CORE_PEER_LOCALMSPID="Org2MSP"
export CORE_PEER_TLS_ROOTCERT_FILE=${PWD}/organizations/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt
export CORE_PEER_MSPCONFIGPATH=${PWD}/organizations/peerOrganizations/org2.example.com/users/Admin@org2.example.com/msp
export CORE_PEER_ADDRESS=localhost:9051
保存退出
source /etc/profile
啟動測試網絡：
./network.sh up
./network.sh createChannel
./network.sh deployCC
運行如下命令初始化資產分類賬：
peer chaincode invoke -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --tls --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C mychannel -n basic --peerAddresses localhost:7051 --tlsRootCertFiles ${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt --peerAddresses localhost:9051 --tlsRootCertFiles ${PWD}/organizations/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt -c '{"function":"InitLedger","Args":[]}'
如果有如下報錯信息，可能是鏈碼沒有在通道中被成功定義，關閉測試網絡后，重新執行啟動網絡操作：
Error: endorsement failure during invoke. response: status:500 message:"make sure the chaincode basic has been successfully defined on channel mychannel and try again: chaincode basic not found"
上述初始化指令的執行成功返回結果信息如下：
2020-08-28 11:20:52.062 CST [chaincodeCmd] chaincodeInvokeOrQuery -> INFO 001 Chaincode invoke successful. result: status:200
運行以下命令獲取添加到通道分類賬的資產列表：
peer chaincode query -C mychannel -n basic -c '{"Args":["GetAllAssets"]}'
返回結果如下：
[{"ID":"asset1","color":"blue","size":5,"owner":"Tomoko","appraisedValue":300},{"ID":"asset2","color":"red","size":5,"owner":"Brad","appraisedValue":400},{"ID":"asset3","color":"green","size":10,"owner":"Jin Soo","appraisedValue":500},{"ID":"asset4","color":"yellow","size":10,"owner":"Max","appraisedValue":600},{"ID":"asset5","color":"black","size":15,"owner":"Adriana","appraisedValue":700},{"ID":"asset6","color":"white","size":15,"owner":"Michel","appraisedValue":800}]
當網絡成員希望轉移或更改分類賬上的資產時，會調用鏈碼。使用以下命令更改分類賬上的資產所有者：
peer chaincode invoke -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --tls --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C mychannel -n basic --peerAddresses localhost:7051 --tlsRootCertFiles ${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt --peerAddresses localhost:9051 --tlsRootCertFiles ${PWD}/organizations/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt -c '{"function":"TransferAsset","Args":["asset6","Christopher"]}'
返回如下提示信息，即表示更改成功：
2020-08-28 11:21:29.252 CST [chaincodeCmd] chaincodeInvokeOrQuery -> INFO 001 Chaincode invoke successful. result: status:200
使用如下命令查詢剛剛的轉移信息：
peer chaincode query -C mychannel -n basic -c '{"Args":["ReadAsset","asset6"]}'
返回結果如下：
{"ID":"asset6","color":"white","size":15,"owner":"Christopher","appraisedValue":800}
（如果是提示某些文件不存在，我的一個解決辦法是，啟動網絡前，source /etc/profile）
