Blockchain-Fabric操作手记

docker exec -it dockercompose_vp0_1 bash

# 由多个预设的用户，有两种注册的方式

peer network login test_user0 -p MS9qrN8hFjlE

# 或者在Rest APIs中

{
  "enrollId": "jim",
  "enrollSecret": "6avZQLwcUe9b"
}

### 进入对应主机
docker exec -it dockercompose_vp0_1 bash

### cd /home/blockchain/fabric-images/docker-compose/base
### 备份一下peer-secure-pbft-base.yaml
cp peer-secure-pbft-base.yaml backup-pbft.yaml

开始编辑peer-secure-pbft-base.yaml,

version: '2'
services:
  peer-secure-pbft-base:
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
    environment:
      - CORE_PEER_DISCOVERY_PERIOD=60s
      - CORE_PEER_DISCOVERY_TOUCHPERIOD=61s
      - CORE_PEER_ADDRESSAUTODETECT=true
      - CORE_VM_ENDPOINT=unix:///var/run/docker.sock
      - CORE_LOGGING_LEVEL=DEBUG
      - CORE_PEER_PKI_ECA_PADDR=membersrvc:7054
      - CORE_PEER_PKI_TCA_PADDR=membersrvc:7054
      - CORE_PEER_PKI_TLSCA_PADDR=membersrvc:7054
      - CORE_SECURITY_ENABLED=true
      - CORE_PEER_VALIDATOR_CONSENSUS_PLUGIN=pbft
      - CORE_PBFT_GENERAL_MODE=batch
      - CORE_PBFT_GENERAL_N=4
    command: sh -c "sleep 10; peer node start --peer-chaincodedev" # 修改这里

保存后继续：

### 删除已有的docker容器
docker rm -f $(docker ps -aq)

### 将自己的脚本复制到容器中的某个目录中
docker cp ./give-up-chat.go b489632aa29e:/opt/gopath/src/github.com/giveup

### 进入/opt/gopath/src/github.com/giveup
go build

### 设置Chaincode ID Name, 开始运行
CORE_CHAINCODE_ID_NAME=mycc2 CORE_PEER_ADDRESS=0.0.0.0:7051 ./giveup

至此，本地开发模式已经完成。之后可以再打开一个shell对已有的chaincode节点进行操作。
