Hyperledger Fabric动态配置Raft节点

最近看官方文档发现新的共识算法etcdRaft允许动态添加或删除排序节点，所以也花了一天时间操作了以下，写篇文章把整个过程记录一下。
初始网络本文设置了4个Orderer节点，1个Peer节点(用于更新配置文件以及测试用),然后动态添加第五个Orderer节点。
本文分成两个部分:

第一部分是手动通过Fabric-CA生成每一个节点的证书文件第二部分是更新Fabric网络配置添加新的Orderer节点。

本文基于Fabric v2.0.0-beta版本。版本号只要高于1.4.1就行

1 搭建定制化的Fabric网络

前提条件是成功跑起来Fabric的示例网络，可以看这里->Hyperledger Fabric环境搭建

首先在$GOPATH下(本文路径地址为$GOPATH/src/github.com/hyperledger/fab)建立如下几个文件夹用于之后的操作:

.  # 这里是根目录fab
├── ca    # 用于生成CA证书的ca配置文件的文件夹
│   ├── org1
│   │   └── fabric-ca-server-config.yaml
│   └── server
│       └── fabric-ca-server-config.yaml
├── channel-artifacts    #用于保存创世区块以及通道配置文件
├── configtx.yaml      #配置文件：用于生成创世区块以及通道配置文件
├── crypto-config     #存储生成的证书文件
├── docker      # Fabric网络节点通过Docker启动，用于启动节点的Docker文件
│   ├── base.yaml
│   ├── docker-compose-addOrderer5.yaml
│   ├── docker-compose-ca.yaml
│   ├── docker-compose-orderers.yaml
│   └── docker-compose-peer.yaml
└── store    #存储区块等信息

以下所有操作默认都在根目录文件夹内！

1.1CA配置文件

docker-compose-ca.yaml文件:

展开查看docker-compose-ca.yaml文件

    image: hyperledger/fabric-ca:1.4.4
    environment:
      - FABRIC_CA_HOME=/etc/hyperledger/fabric-ca-server
      - FABRIC_CA_SERVER_CA_NAME=ca-orderer
      - FABRIC_CA_SERVER_TLS_ENABLED=true
      - FABRIC_CA_SERVER_PORT=9054
    ports:
      - "9054:9054"
    command: sh -c 'fabric-ca-server start -b admin:adminpw -d'
    volumes:
      - ../ca/server:/etc/hyperledger/fabric-ca-server
    container_name: ca_orderer
  ca0:
    image: hyperledger/fabric-ca:1.4.4
    environment:

      - FABRIC_CA_SERVER_CA_NAME=ca-org1
      - FABRIC_CA_SERVER_TLS_ENABLED=true
      - FABRIC_CA_SERVER_PORT=7054
    ports:
      - "7054:7054"
    command: sh -c 'fabric-ca-server start -b admin:adminpw -d'
    volumes:
      - ../ca/org1:/etc/hyperledger/fabric-ca-server
    container_name: ca_org1

将以上三个文件保存到指定的路径，然后使用以下命令启动CA服务器： docker-compose -f docker/docker-compose-ca.yaml up -d

服务器会自动读取上面的两个配置文件，并初始化CA服务器。
当然，服务器配置文件将自动生成在ca/server/子文件夹内，其中最主要使用到的是tls-cert.pem文件。

1.2 注册Orderer节点

首先配置环境变量并登陆管理员账号:

#创建存储Order节点证书的子文件夹。
mkdir -p crypto-config/orderOrganization/example.com
export FABRIC_CA_CLIENT_HOME=${PWD}/crypto-config/orderOrganization/example.com
fabric-ca-client enroll -u https://admin:adminpw@localhost:9054 --caname ca-orderer --tls.certfiles ${PWD}/ca/server/tls-cert.pem

生成节点类型分类配置文件(不知道这个文件应该称作什么，暂且使用这个名字称呼好了):

  echo 'NodeOUs:
  Enable: true
  ClientOUIdentifier:
    Certificate: cacerts/localhost-9054-ca-orderer.pem
    OrganizationalUnitIdentifier: client
  PeerOUIdentifier:
    Certificate: cacerts/localhost-9054-ca-orderer.pem
    OrganizationalUnitIdentifier: peer
  AdminOUIdentifier:
    Certificate: cacerts/localhost-9054-ca-orderer.pem
    OrganizationalUnitIdentifier: admin
  OrdererOUIdentifier:
    Certificate: cacerts/localhost-9054-ca-orderer.pem
    OrganizationalUnitIdentifier: orderer' > ${PWD}/crypto-config/orderOrganization/example.com/msp/config.yaml

之后注册网络中初始的4个Orderer节点:

fabric-ca-client register -u https://admin:adminpw@localhost:9054 --caname ca-orderer --id.name orderer1 --id.secret ordererpw --id.type orderer --id.attrs '"hf.Registrar.Roles=orderer"' --tls.certfiles ${PWD}/ca/server/tls-cert.pem
fabric-ca-client register -u https://admin:adminpw@localhost:9054 --caname ca-orderer --id.name orderer2 --id.secret ordererpw --id.type orderer --id.attrs '"hf.Registrar.Roles=orderer"' --tls.certfiles ${PWD}/ca/server/tls-cert.pem
fabric-ca-client register -u https://admin:adminpw@localhost:9054 --caname ca-orderer --id.name orderer3 --id.secret ordererpw --id.type orderer --id.attrs '"hf.Registrar.Roles=orderer"' --tls.certfiles ${PWD}/ca/server/tls-cert.pem
fabric-ca-client register -u https://admin:adminpw@localhost:9054 --caname ca-orderer --id.name orderer4 --id.secret ordererpw --id.type orderer --id.attrs '"hf.Registrar.Roles=orderer"' --tls.certfiles ${PWD}/ca/server/tls-cert.pem

fabric-ca-client register -u https://admin:adminpw@localhost:9054 --caname ca-orderer --id.name ordererAdmin --id.secret ordererAdminpw --id.type admin --id.attrs '"hf.Registrar.Roles=admin"' --tls.certfiles ${PWD}/ca/server/tls-cert.pem

1.3 获取Orderer证书文件

为刚刚创建的几个用户创建各自的文件夹用于存储证书文件:

mkdir -p crypto-config/orderOrganization/example.com/orderers
mkdir -p crypto-config/orderOrganization/example.com/orderers/orderer1.example.com
mkdir -p crypto-config/orderOrganization/example.com/orderers/orderer2.example.com
mkdir -p crypto-config/orderOrganization/example.com/orderers/orderer3.example.com
mkdir -p crypto-config/orderOrganization/example.com/orderers/orderer4.example.com

接下来获取每一个Orderer节点的MSP证书文件:

fabric-ca-client enroll -u https://orderer1:ordererpw@localhost:9054 --caname ca-orderer -M ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer1.example.com/msp --csr.hosts orderer1.example.com --tls.certfiles ${PWD}/ca/server/tls-cert.pem
fabric-ca-client enroll -u https://orderer2:ordererpw@localhost:9054 --caname ca-orderer -M ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer2.example.com/msp --csr.hosts orderer2.example.com --tls.certfiles ${PWD}/ca/server/tls-cert.pem
fabric-ca-client enroll -u https://orderer3:ordererpw@localhost:9054 --caname ca-orderer -M ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer3.example.com/msp --csr.hosts orderer3.example.com --tls.certfiles ${PWD}/ca/server/tls-cert.pem
fabric-ca-client enroll -u https://orderer4:ordererpw@localhost:9054 --caname ca-orderer -M ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer4.example.com/msp --csr.hosts orderer4.example.com --tls.certfiles ${PWD}/ca/server/tls-cert.pem

还有每一个节点的TLS证书:

fabric-ca-client enroll -u https://orderer1:ordererpw@localhost:9054 --caname ca-orderer -M ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer1.example.com/tls --enrollment.profile tls --csr.hosts orderer1.example.com --tls.certfiles ${PWD}/ca/server/tls-cert.pem
fabric-ca-client enroll -u https://orderer2:ordererpw@localhost:9054 --caname ca-orderer -M ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer2.example.com/tls --enrollment.profile tls --csr.hosts orderer2.example.com --tls.certfiles ${PWD}/ca/server/tls-cert.pem
fabric-ca-client enroll -u https://orderer3:ordererpw@localhost:9054 --caname ca-orderer -M ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer3.example.com/tls --enrollment.profile tls --csr.hosts orderer3.example.com --tls.certfiles ${PWD}/ca/server/tls-cert.pem
fabric-ca-client enroll -u https://orderer4:ordererpw@localhost:9054 --caname ca-orderer -M ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer4.example.com/tls --enrollment.profile tls --csr.hosts orderer4.example.com --tls.certfiles ${PWD}/ca/server/tls-cert.pem

将之前生成的节点类型分类配置文件拷贝到每一个节点的MSP文件夹:

cp ${PWD}/crypto-config/orderOrganization/example.com/msp/config.yaml ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer1.example.com/msp/config.yaml
cp ${PWD}/crypto-config/orderOrganization/example.com/msp/config.yaml ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer2.example.com/msp/config.yaml
cp ${PWD}/crypto-config/orderOrganization/example.com/msp/config.yaml ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer3.example.com/msp/config.yaml
cp ${PWD}/crypto-config/orderOrganization/example.com/msp/config.yaml ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer4.example.com/msp/config.yaml

然后为每一个节点的TLS证书以及秘钥文件修改名字，方便之后的使用:

cp ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer1.example.com/tls/tlscacerts/* ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer1.example.com/tls/ca.crt
cp ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer1.example.com/tls/signcerts/* ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer1.example.com/tls/server.crt
cp ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer1.example.com/tls/keystore/* ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer1.example.com/tls/server.key
cp ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer2.example.com/tls/tlscacerts/* ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer2.example.com/tls/ca.crt
cp ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer2.example.com/tls/signcerts/* ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer2.example.com/tls/server.crt
cp ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer2.example.com/tls/keystore/* ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer2.example.com/tls/server.key
cp ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer3.example.com/tls/tlscacerts/* ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer3.example.com/tls/ca.crt
cp ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer3.example.com/tls/signcerts/* ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer3.example.com/tls/server.crt
cp ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer3.example.com/tls/keystore/* ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer3.example.com/tls/server.key
cp ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer4.example.com/tls/tlscacerts/* ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer4.example.com/tls/ca.crt
cp ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer4.example.com/tls/signcerts/* ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer4.example.com/tls/server.crt
cp ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer4.example.com/tls/keystore/* ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer4.example.com/tls/server.key

然后在MSP文件夹内创建tlscacerts文件夹，并将TLS文件拷贝过去:

mkdir ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer1.example.com/msp/tlscacerts
mkdir ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer2.example.com/msp/tlscacerts
mkdir ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer3.example.com/msp/tlscacerts
mkdir ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer4.example.com/msp/tlscacerts
cp ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer1.example.com/tls/tlscacerts/* ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer1.example.com/msp/tlscacerts/tlsca.example.com-cert.pem
cp ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer2.example.com/tls/tlscacerts/* ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer2.example.com/msp/tlscacerts/tlsca.example.com-cert.pem
cp ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer3.example.com/tls/tlscacerts/* ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer3.example.com/msp/tlscacerts/tlsca.example.com-cert.pem
cp ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer4.example.com/tls/tlscacerts/* ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer4.example.com/msp/tlscacerts/tlsca.example.com-cert.pem

复制TLS根证书:

mkdir -p ${PWD}/crypto-config/orderOrganization/example.com/msp/tlscacerts
cp ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer1.example.com/tls/tlscacerts/* ${PWD}/crypto-config/orderOrganization/example.com/msp/tlscacerts/tlsca.example.com-cert.pem

最后是Admin节点的证书文件:

#首先也是创建文件夹
mkdir -p crypto-config/orderOrganization/example.com/users
mkdir -p crypto-config/orderOrganization/example.com/users/Admin@example.com
#获取证书文件
fabric-ca-client enroll -u https://ordererAdmin:ordererAdminpw@localhost:9054 --caname ca-orderer -M ${PWD}/crypto-config/orderOrganization/example.com/users/Admin@example.com/msp --tls.certfiles ${PWD}/ca/server/tls-cert.pem
cp ${PWD}/crypto-config/orderOrganization/example.com/msp/config.yaml ${PWD}/crypto-config/orderOrganization/example.com/users/Admin@example.com/msp/config.yaml

到这里Orderer节点证书已经生成完毕(可以根据实际需要修改Orderer节点数量，最少不能低于3个)，接下来是网络中唯一的peer节点的配置文件生成:

1.4 注册Peer节点

和上面步骤相同，首先创建子文件夹用于存储证书文件:

mkdir -p crypto-config/peerOrganizations/org1.example.com/

配置环境变量并登陆管理员身份:

export FABRIC_CA_CLIENT_HOME=${PWD}/crypto-config/peerOrganizations/org1.example.com/
fabric-ca-client enroll -u https://admin:adminpw@localhost:7054 --caname ca-org1 --tls.certfiles ${PWD}/ca/org1/tls-cert.pem

生成节点类型分类配置文件:

echo 'NodeOUs:
  Enable: true
  ClientOUIdentifier:
    Certificate: cacerts/localhost-7054-ca-org1.pem
    OrganizationalUnitIdentifier: client
  PeerOUIdentifier:
    Certificate: cacerts/localhost-7054-ca-org1.pem
    OrganizationalUnitIdentifier: peer
  AdminOUIdentifier:
    Certificate: cacerts/localhost-7054-ca-org1.pem
    OrganizationalUnitIdentifier: admin
  OrdererOUIdentifier:
    Certificate: cacerts/localhost-7054-ca-org1.pem
    OrganizationalUnitIdentifier: orderer' > ${PWD}/crypto-config/peerOrganizations/org1.example.com/msp/config.yaml

虽然网络中只有一个peer节点，但是我们需要注册三个用户:peer0,user1,org1admin，其中第一个是必需的，第二个是用于测试的，第三个为Admin用户，安装和实例化链码需要Admin用户的证书:

fabric-ca-client register -u https://admin:adminpw@localhost:7054 --caname ca-org1 --id.name peer0 --id.secret peer0pw --id.type peer --id.attrs '"hf.Registrar.Roles=peer"' --tls.certfiles ${PWD}/ca/org1/tls-cert.pem
fabric-ca-client register -u https://admin:adminpw@localhost:7054 --caname ca-org1 --id.name user1 --id.secret user1pw --id.type client --id.attrs '"hf.Registrar.Roles=client"' --tls.certfiles ${PWD}/ca/org1/tls-cert.pem
fabric-ca-client register -u https://admin:adminpw@localhost:7054 --caname ca-org1 --id.name org1admin --id.secret org1adminpw --id.type admin --id.attrs '"hf.Registrar.Roles=admin"' --tls.certfiles ${PWD}/ca/org1/tls-cert.pem

1.5 获取Peer节点证书文件

节点注册完毕，获取他们的证书文件:
创建子文件夹:

mkdir -p crypto-config/peerOrganizations/org1.example.com/peers
mkdir -p crypto-config/peerOrganizations/org1.example.com/peers/peer0.org1.example.co

获取证书文件:

#MSP文件

#TLS证书
fabric-ca-client enroll -u https://peer0:peer0pw@localhost:7054 --caname ca-org1 -M ${PWD}/crypto-config/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls --enrollment.profile tls --csr.hosts peer0.org1.example.com --csr.hosts localhost --tls.certfiles ${PWD}/ca/org1/tls-cert.pem

拷贝节点分类配置文件:

cp ${PWD}/crypto-config/peerOrganizations/org1.example.com/msp/config.yaml ${PWD}/crypto-config/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/msp/config.yaml

修改证书以及秘钥文件，方便之后使用:

cp ${PWD}/crypto-config/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/tlscacerts/* ${PWD}/crypto-config/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt
cp ${PWD}/crypto-config/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/signcerts/* ${PWD}/crypto-config/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/server.crt
cp ${PWD}/crypto-config/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/keystore/* ${PWD}/crypto-config/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/server.key

将TLS相关证书复制一份:

mkdir ${PWD}/crypto-config/peerOrganizations/org1.example.com/msp/tlscacerts
cp ${PWD}/crypto-config/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/tlscacerts/* ${PWD}/crypto-config/peerOrganizations/org1.example.com/msp/tlscacerts/ca.crt
mkdir ${PWD}/crypto-config/peerOrganizations/org1.example.com/tlsca
cp ${PWD}/crypto-config/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/tlscacerts/* ${PWD}/crypto-config/peerOrganizations/org1.example.com/tlsca/tlsca.org1.example.com-cert.pem
mkdir ${PWD}/crypto-config/peerOrganizations/org1.example.com/ca
cp ${PWD}/crypto-config/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/msp/cacerts/* ${PWD}/crypto-config/peerOrganizations/org1.example.com/ca/ca.org1.example.com-cert.pem

获取user与Admin用户证书文件:

#创建子文件夹
mkdir -p crypto-config/peerOrganizations/org1.example.com/users
mkdir -p crypto-config/peerOrganizations/org1.example.com/users/User1@org1.example.com
mkdir -p crypto-config/peerOrganizations/org1.example.com/users/Admin@org1.example.com
#获取证书文件
fabric-ca-client enroll -u https://user1:user1pw@localhost:7054 --caname ca-org1 -M ${PWD}/crypto-config/peerOrganizations/org1.example.com/users/User1@org1.example.com/msp --tls.certfiles ${PWD}/ca/org1/tls-cert.pem
fabric-ca-client enroll -u https://org1admin:org1adminpw@localhost:7054 --caname ca-org1 -M ${PWD}/crypto-config/peerOrganizations/org1.example.com/users/Admin@org1.example.com/msp --tls.certfiles ${PWD}/ca/org1/tls-cert.pem
cp ${PWD}/crypto-config/peerOrganizations/org1.example.com/msp/config.yaml ${PWD}/crypto-config/peerOrganizations/org1.example.com/users/Admin@org1.example.com/msp/config.yaml

1.6 启动网络之前的准备

到这里我们已经生成了所有需要的证书文件，接下来是生成用于启动网络的创世区块,生成创世区块需要一个文件configtx.yaml,直接复制过来:

展开查看configtx.yaml

将该文件保存到指定位置，接下来生成创世区块:

export FABRIC_CFG_PATH=$PWD
configtxgen -profile SampleMultiNodeEtcdRaft -channelID byfn-sys-channel -outputBlock ./channel-artifacts/genesis.block
# 生成通道配置文件
export CHANNEL_NAME=mychannel
configtxgen -profile TwoOrgsChannel -outputCreateChannelTx ./channel-artifacts/mychannel.tx -channelID $CHANNEL_NAME

1.7 启动网络

首先写包含所有节点的Docker文件,这里直接贴出来:

展开查看base.yaml

version: '2'
services:
  orderer-base:
    image: hyperledger/fabric-orderer:2.0.0-beta
    environment:
      - FABRIC_LOGGING_SPEC=INFO
#      - FABRIC_LOGGING_SPEC=DEBUG
      - ORDERER_GENERAL_LISTENADDRESS=0.0.0.0
      - ORDERER_GENERAL_BOOTSTRAPMETHOD=file
      - ORDERER_GENERAL_BOOTSTRAPFILE=/var/hyperledger/orderer/orderer.genesis.block
      - ORDERER_GENERAL_LOCALMSPID=OrdererMSP
      - ORDERER_GENERAL_LOCALMSPDIR=/var/hyperledger/orderer/msp
      # enabled TLS
      - ORDERER_GENERAL_TLS_ENABLED=true
      - ORDERER_GENERAL_TLS_PRIVATEKEY=/var/hyperledger/orderer/tls/server.key
      - ORDERER_GENERAL_TLS_CERTIFICATE=/var/hyperledger/orderer/tls/server.crt
      - ORDERER_GENERAL_TLS_ROOTCAS=[/var/hyperledger/orderer/tls/ca.crt]
      - ORDERER_GENERAL_CLUSTER_CLIENTCERTIFICATE=/var/hyperledger/orderer/tls/server.crt
      - ORDERER_GENERAL_CLUSTER_CLIENTPRIVATEKEY=/var/hyperledger/orderer/tls/server.key
      - ORDERER_GENERAL_CLUSTER_ROOTCAS=[/var/hyperledger/orderer/tls/ca.crt]
    working_dir: /opt/gopath/src/github.com/hyperledger/fabric
    command: orderer

然后是Orderer节点的Docker文件:

展开查看docker-compose-orderers.yaml

    ports:
      - 10050:10050

最后一个是peer节点的Docker文件：

展开查看docker-compose-peer.yaml

version: '2'
volumes:

      - byfn

将以上文件保存到指定位置后，使用以下命令直接启动: docker-compose -f docker/docker-compose-orderers.yaml -f docker/docker-compose-peer.yaml up -d

启动完成后可以查看每个节点的日志确认节点成功运行:

docker logs orderer1.example.com
...
docker logs peer0.org1.example.com

如果没有错误的话就可以进行第二部分了，如果出现错误则要回去检查是不是哪里漏掉了。

1.8 简单测试

先进行第一部分的测试，看一下创建通道，加入通道是否成功:

#进入CLI容器
docker exec -it cli bash
#配置环境变量
export CHANNEL_NAME=mychannel
export ORDERER_CA=${PWD}/crypto/orderOrganization/example.com/orderers/orderer1.example.com/msp/tlscacerts/tlsca.example.com-cert.pem
export PEER0_ORG1_CA=${PWD}/crypto/peerOrganization/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt
export CORE_PEER_LOCALMSPID="Org1MSP"
export CORE_PEER_TLS_ROOTCERT_FILE=$PEER0_ORG1_CA
export CORE_PEER_MSPCONFIGPATH=${PWD}/crypto/peerOrganizations/org1.example.com/users/Admin@org1.example.com/msp
export CORE_PEER_ADDRESS=peer0.org1.example.com:7051

创建通道:

peer channel create -o orderer1.example.com:7050 -c $CHANNEL_NAME -f ./channel-artifacts/mychannel.tx --tls $CORE_PEER_TLS_ENABLED --cafile $ORDERER_CA --outputBlock ./channel-artifacts/${CHANNEL_NAME}.block

加入通道:

peer channel join -b ./channel-artifacts/$CHANNEL_NAME.block

如果一切顺利的话，网络就成功搭建起来了，至于链码就不再测试了。
直接到第二部分，动态添加一个Orderer节点。

2 动态添加Raft节点

主要步骤如下：

为该节点生成证书文件获取当前网络的配置文件将证书文件添加到配置文件中更新配置文件启动新的Orderer节点 2.1 生成证书文件 2.1.1 注册该节点身份

fabric-ca-client register -u https://admin:adminpw@localhost:9054 --caname ca-orderer --id.name orderer5 --id.secret ordererpw --id.type orderer --id.attrs '"hf.Registrar.Roles=orderer"' --tls.certfiles ${PWD}/ca/server/tls-cert.pem

为该节点创建存储证书的文件夹:

mkdir -p crypto-config/orderOrganization/example.com/orderers/orderer5.example.com 2.1.2 获取该节点证书

#MSP
fabric-ca-client enroll -u https://orderer5:ordererpw@localhost:9054 --caname ca-orderer -M ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer5.example.com/msp --csr.hosts orderer5.example.com --tls.certfiles ${PWD}/ca/server/tls-cert.pem
#TLS
fabric-ca-client enroll -u https://orderer5:ordererpw@localhost:9054 --caname ca-orderer -M ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer5.example.com/tls --enrollment.profile tls --csr.hosts orderer5.example.com --tls.certfiles ${PWD}/ca/server/tls-cert.pem

复制节点分类配置文件:

cp ${PWD}/crypto-config/orderOrganization/example.com/msp/config.yaml ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer5.example.com/msp/config.yaml

修改证书与秘钥文件名称:

cp ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer5.example.com/tls/tlscacerts/* ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer5.example.com/tls/ca.crt
cp ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer5.example.com/tls/signcerts/* ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer5.example.com/tls/server.crt
cp ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer5.example.com/tls/keystore/* ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer5.example.com/tls/server.key

创建文件夹并拷贝TLS证书文件:

mkdir ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer5.example.com/msp/tlscacerts
cp ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer5.example.com/tls/tlscacerts/* ${PWD}/crypto-config/orderOrganization/example.com/orderers/orderer5.example.com/msp/tlscacerts/tlsca.example.com-cert.pem

2.2 获取网络配置文件

将节点添加进网络，首先需要将该节点添加到系统通道内，所以先获取系统通道的配置文件:
进入cli容器:

docker exec -it cli bash

配置环境变量，需要使用Orderer节点的身份信息:

export CORE_PEER_LOCALMSPID="OrdererMSP"
export ORDERER_CA=${PWD}/crypto/orderOrganization/example.com/orderers/orderer1.example.com/msp/tlscacerts/tlsca.example.com-cert.pem
export CORE_PEER_TLS_ROOTCERT_FILE=${PWD}/crypto/ordererOrganization/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem
export CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/orderOrganization/example.com/users/Admin@example.com/msp
export CORE_PEER_ADDRESS=peer0.org1.example.com:7051

获取系统通道配置文件:

peer channel fetch config channel-artifacts/config_block.pb -o orderer1.example.com:7050 -c byfn-sys-channel --tls --cafile $ORDERER_CA

解码该配置文件:

configtxlator proto_decode --input channel-artifacts/config_block.pb --type common.Block | jq .data.data[0].payload.data.config > channel-artifacts/config.json

2.3将证书文件添加到配置文件中

退出容器，可以在channel-artifacts文件内找到config.json文件。将该文件复制一份并在channel-artifacts文件夹下保存为update_config.json,使用编辑工具打开，并搜索.example.com字段如下：
字段一部分：

  {
    "client_tls_cert": "一连串的字符串",
    "host": "orderer1.example.com",
    "port": 7050,
    "server_tls_cert": "一连串的字符串"
  }

以及匹配到的第二部分的字段:

      "OrdererAddresses": {
        "mod_policy": "/Channel/Orderer/Admins",
        "value": {
          "addresses": [
            "orderer1.example.com:7050",
            "orderer2.example.com:8050",
            "orderer3.example.com:9050",
            "orderer4.example.com:10050"
          ]
        },
        "version": "0"
    }

在字段一部分，需要将我们生成的新的节点的证书添加上去，其中证书文件地址为:

crypto-config/ordererOrganizations/example.com/orderers/orderer5.example.com/tls/server.crt

使用BASE64转码:

cat crypto-config/ordererOrganizations/example.com/orderers/orderer5.example.com/tls/server.crt | base64 > cert.txt

在update_config.json文件中字段一的部分下面按照字段一的格式添加相同的代码块，并进行修改：
将cert.txt文件中的内容复制到字段一的client_tls_cert,server_tls_cert对应部分，并修改host对应部分为orderer5.example.com，port为11050.

2.4更新配置文件

接下来进入cli容器:

docker exec -it cli bash

对原有的配置文件与更新的配置文件进行编码:

configtxlator proto_encode --input channel-artifacts/config.json --type common.Config > channel-artifacts/config.pb
configtxlator proto_encode --input channel-artifacts/update_config.json --type common.Config > channel-artifacts/config_update.pb

计算出两个文件的差异:

configtxlator compute_update --channel_id byfn-sys-channel --original channel-artifacts/config.pb --updated channel-artifacts/config_update.pb > channel-artifacts/updated.pb

对该文件进行解码，并添加用于更新配置的头部信息:

configtxlator proto_decode --input channel-artifacts/updated.pb --type common.ConfigUpdate > channel-artifacts/updated.json
echo '{"payload":{"header":{"channel_header":{"channel_id":"byfn-sys-channel", "type":2}},"data":{"config_update":'$(cat channel-artifacts/updated.json)'}}}' | jq . > channel-artifacts/updated_envelope.json

编码为Envelope格式的文件:

configtxlator proto_encode --input channel-artifacts/updated_envelope.json --type common.Envelope > channel-artifacts/updated_envelope.pb

对该文件进行签名操作，用于更新配置:

peer channel signconfigtx -f channel-artifacts/updated_envelope.pb

提交更新通道配置交易:

peer channel update -f channel-artifacts/updated_envelope.pb -c byfn-sys-channel -o orderer1.example.com:7050 --tls true --cafile $ORDERER_CA

如果没有错误的话，新的Orderer节点证书已经成功添加到网络配置中，接下来可以启动新的节点了:

2.5 启动新的Orderer节点

写一下新的Orderer节点的Docker文件:

展开查看docker-compose-addOrderer5.yaml


version: '2'
volumes:
  orderer5.example.com:
networks:
  byfn:
services:
  orderer5.example.com:
    extends:
      file: base.yaml
      service: orderer-base
    environment:
      - ORDERER_GENERAL_LISTENPORT=11050
    container_name: orderer5.example.com
    networks:
      - byfn
    volumes:
      - ../channel-artifacts/genesis.block:/var/hyperledger/orderer/orderer.genesis.block
      - ../crypto-config/orderOrganization/example.com/orderers/orderer5.example.com/msp:/var/hyperledger/orderer/msp
      - ../crypto-config/orderOrganization/example.com/orderers/orderer5.example.com/tls/:/var/hyperledger/orderer/tls
      - ../store/o5:/var/hyperledger/production/orderer
    ports:
      - 11050:11050

直接通过命令启动它: docker-compose -f docker-compose-addOrderer5.yaml up -d

可以查看新节点的日志确认新的节点已经成功加入了网络。

到这里，本文成功把新的Orderer节点添加进了网络，但是只将该节点添加到了系统通道内，对于应用通道mychannel来说，新的节点并没有添加进来，将新的节点添加进mychannel通道和以上步骤相同，只需要将通道名称由系统通道修改为mychannel即可。本文便不再说明了。
而动态删除节点的过程与添加相似，只不过是从配置文件中删除节点证书。
