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:

services:
  ca:
    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_HOME=/etc/hyperledger/fabric-ca-server
      - 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
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/msp --csr.hosts peer0.org1.example.com --tls.certfiles ${PWD}/ca/org1/tls-cert.pem
#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:

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:

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:

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:


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。
