Minifab

Install Minifab:

1. mkdir -p ~/mywork && cd ~/mywork && curl -o minifab -sL https://tinyurl.com/yxa2q6yr && chmod +x minifab
2. sudo mv minifab /usr/local/bin/
3. minifab -h
4. New spec.yaml

   fabric:
      cas:
      - "ca0.org1.example.com"
      peers: 
      - "peer0.org1.example.com"
      - "peer1.org1.example.com"
      settings:
         ca:
            FABRIC_LOGGING_SPEC: DEBUG
         peer:
            FABRIC_LOGGING_SPEC: INFO
         orderer:
            FABRIC_LOGGING_SPEC: DEBUG
      netname: "mynet"
   

5. Start Minifab:

   cd ~/mywork
   minifab netup -e 7788 -i 1.4.7 -o org1.example.com
   

Minifab增加peer:

1. 在minifab运行中的状态下：spec.yaml中加入新的peer

2. minifab down

3. vars/crypto-config.yaml增加新的peer

4. 生成新增peer的证书信息:

   sudo /home/opc/cathy/workspace/go/src/github.com/fabric-samples-1.4/bin/cryptogen extend --input=vars/keyfiles --config=vars/crypto-config.yaml

   缺失的admin cert可以从其它peer上考过来：

   sudo cp vars/keyfiles/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/msp/admincerts/Admin@org1.example.com-cert.pem vars/keyfiles/peerOrganizations/org1.example.com/peers/peer1.org1.example.com/msp/admincerts/

   sudo rm vars/node_vars.json

   sudo rm vars/run/peer0.org1.example.com.env vars/run/peer1.org1.example.com.env

5. minifab netup 有时候会不成功关掉再重启下，或者把2,4,5步重复做就行了
