Fabric配置fabric-sample工程目录，并生成证书

Posted 2021-08-30 sanqima

    GitHub上的fabric-sample工程，默认只有源码，缺少CA工具和加密工具，它需要从其他地方下载CA工具和加密工具，这里以fabric v1.4.0为例进行说明。步骤如下：

1、下载fabric-sample v1.4.0源码

    官网地址： fabric-sample v1.4.0

# 创建hyperleger目录
mkdir -p $GOPATH/src/github.com/hyperledger
cd $GOPATH/src/github.com/hyperledger

# 克隆fabric-samples项目并切换到v1.4tag
git clone https://github.com/hyperledger/fabric-samples.git
cd fabric-samples
git checkout -b sample v1.4.0

2、下载fabric v1.4.0 CA工具

    官网地址： fabric v1.4.0加密工具

wget https://nexus.hyperledger.org/content/repositories/releases/org/hyperledger/fabric-ca/hyperledger-fabric-ca/linux-amd64-1.4.0/hyperledger-fabric-ca-linux-amd64-1.4.0.tar.gz

3、下载fabric v1.4.0 加密工具

    官网地址： fabric v1.4.0 CA工具

wget https://nexus.hyperledger.org/content/repositories/releases/org/hyperledger/fabric/hyperledger-fabric/linux-amd64-1.4.0/hyperledger-fabric-linux-amd64-1.4.0.tar.gz

4、配置fabric-sample工程目录

# 将这2个工具解压到 fabric-samples目录下
tar zxvf hyperledger-fabric-linux-amd64-1.4.0.tar.gz -C $GOPATH/src/github.com/hyperledger/fabric-samples/
tar zxvf hyperledger-fabric-ca-linux-amd64-1.4.0.tar.gz -C $GOPATH/src/github.com/hyperledger/fabric-samples/

#向/etc/profile中写入环境变量
sudo echo 'export PATH=$GOPATH/src/github.com/hyperledger/fabric-samples/bin:$PATH' >> /etc/profile

#使环境变量生效
source /etc/profile

    目录结构：

5、使用cryptogen生成证书

5.1 编写证书配置文件crypto-config.yaml

修改fabric-sample/first-network/crypto-config.yaml文件，
Order组织有2个成员: order、order2
Peer组织有2个成员: Org1、Org2
    Org1有2个peer节点，1个User
    Org2有2个peer节点，1个User

OrdererOrgs:
  # ---------------------------------------------------------------------------
  # Orderer
  # ---------------------------------------------------------------------------
  - Name: Orderer
    Domain: example.com
    Specs:
      - Hostname: orderer
      - Hostname: orderer2

# ---------------------------------------------------------------------------
# "PeerOrgs" - Definition of organizations managing peer nodes
# ---------------------------------------------------------------------------
PeerOrgs:
  # ---------------------------------------------------------------------------
  # Org1
  # ---------------------------------------------------------------------------
  - Name: Org1
    Domain: org1.example.com
    EnableNodeOUs: true
    Template:
      Count: 2
    Users:
      Count: 1
  # ---------------------------------------------------------------------------
  # Org2
  # ---------------------------------------------------------------------------
  - Name: Org2
    Domain: org2.example.com
    EnableNodeOUs: true
    Template:
      Count: 2
    Users:
      Count: 1

5.2 根据yaml文件来生成证书

../bin/cryptogen generate --config=./crypto-config.yaml
