超级账本fabic入门
详细的环境安装可以微信扫一扫
1.先进入sample的目录启动服务
cd chaincode-docker-devmode
启动相应的docker实例中使用了已经写了相应的编排文件如下所示
.
├── chaincode
├── docker-compose-simple.yaml
├── msp
│ ├── admincerts
│ │ └── admincert.pem
│ ├── cacerts
│ │ └── cacert.pem
│ ├── keystore
│ │ └── key.pem
│ ├── signcerts
│ │ └── peer.pem
│ ├── tlscacerts
│ │ └── tlsroot.pem
│ └── tlsintermediatecerts
│ └── tlsintermediate.pem
├── myc.block
├── myc.tx
├── orderer.block
├── README.rst
└── script.sh
执行命令这个命令是docker-compose编排启动文件如果想后台运行的话可以加个-d参数
docker-compose -f docker-compose-simple.yaml up
注意如果这里出现了证书错误的情况就切换到master主分支
2.开始编译区块链
在第一步中启动程序会为我们启动一个开发环境的容器名为chinacode，我们编译直接进入该容器进行操作
docker exec -it chaincode bash
我看到默认的主目录为chaincode
root@d2629980e76b:/opt/gopath/src/chaincode#
现在编译sacc
cd sacc
go build
编译完直接运行
CORE_PEER_ADDRESS=peer:7052 CORE_CHAINCODE_ID_NAME=mycc:0 ./sacc
显示如下
/saccchaincode/sacc#CORE_PEER_ADDRESS=peer:7052 CORE_CHAINCODE_ID_NAME=mycc:0 ./sacc
2018-05-04 08:56:18.486 UTC [shim] SetupChaincodeLogging -> INFO 001 Chaincode log level not provided; defaulting to: INFO
2018-05-04 08:56:18.486 UTC [shim] SetupChaincodeLogging -> INFO 002 Chaincode (build level: ) starting up ...
peer容器logs显示已注册channelID不存在
peer | 2018-05-04 09:40:33.425 UTC [chaincode] beforeRegisterEvent -> DEBU 338 Received REGISTER in state created
peer | 2018-05-04 09:40:33.425 UTC [chaincode] registerHandler -> DEBU 339 registered handler complete for chaincode mycc:0
peer | 2018-05-04 09:40:33.425 UTC [chaincode] beforeRegisterEvent -> DEBU 33a Got REGISTER for chaincodeID = name:"mycc:0" , sending back REGISTERED
peer | 2018-05-04 09:40:33.425 UTC [chaincode] notifyDuringStartup -> DEBU 33b nothing to notify (dev mode ?)
peer | 2018-05-04 09:40:33.425 UTC [chaincode] notifyDuringStartup -> DEBU 33c sending READY
peer | 2018-05-04 09:40:33.425 UTC [chaincode] processStream -> DEBU 33d []Move state message READY
peer | 2018-05-04 09:40:33.426 UTC [chaincode] handleMessage -> DEBU 33e []Fabric side Handling ChaincodeMessage of type: READY in state established
peer | 2018-05-04 09:40:33.426 UTC [chaincode] enterReadyState -> DEBU 33f []Entered state ready
peer | 2018-05-04 09:40:33.426 UTC [chaincode] notify -> DEBU 340 notifier Txid:, channelID: does not exist
此时虽然程序已经注册但是未和其他的管道间关联
3.安装实例化
由于上步的执行进行了堵塞的shell，所以这步需要重新开启一个shell进行安装实例化
进入cli开发环境
docker exec -it cli bash
安装
peer chaincode install -p chaincodedev/chaincode/sacc -n mycc -v 0
peer chaincode instantiate -n mycc -v 0 -c '{"Args":["a","10"]}' -C myc
好了这步基本上a向区块链写入了10
如果上步错了想修改20执行如下
peer chaincode invoke -n mycc -c '{"Args":["set", "a", "20"]}' -C myc
想查看下使用如下命令
peer chaincode query -n mycc -c '{"Args":["query","a"]}' -C myc
