引言
啓動一個peer和一個node，用example02作爲例子，安裝、初始化、調用、查詢鏈碼。
環境準備
- macOS Mojave 10.14
- vscode 1.42.0
- golang 1.12.6
- docker-machine 0.16.0
下載源碼
cd $GOPATH/src/github.com/hyperledger/
git clone https://github.com/hyperledger/fabric.git
git checkout release-1.4
git clone https://github.com/hyperledger/fabric-samples
配置host
127.0.0.1 peer
127.0.0.1 orderer
創建peer和order配置
1.在fabric項目下創建dev-network目錄
2.將fabric項目下sampleconfig文件夾下的所有文件複製到 dev-network
3.修改 core.yaml中fileSystemPath = $GOPATH/src/github.com/hyperledger/fabric/dev-network/production/peer
4.修改 orderer.yaml中 Location =$GOPATH/src/github.com/hyperledger/fabric/dev-network/production/orderer
5.在 dev-network新建 config目錄，並複製fabric-samples項目中的chaincode-docker-devmode下的myc.tx和 orderer.block文件到config目錄中
注意修改GOPATH
修改調試配置（.vscode/launch.json），並啓動調試

- 切換到調試窗口，在需要跟蹤的地方打好斷點
- 依次運行order 、peer、channel create 、channel join、chaincode install、run chaincode example02、chaincode instantiate、chaincode invoke、chaincode query
- 觀察debug控制檯和terminal變化
