Fabric1.1 多通道搭建（2 channels）

待我称王封你为后i 2023-10-06 13:21 3阅读 0赞

实践一个 fabric 1.1 多通道部署，在一台服务器中部署完成，并执行 chaincode。

包括：

*  1 orderer
 *  3 Orgs （对应3 peers）
 *  2 channels：  
    channel\_one: Org1、Org2  
    channel\_two: Org1、Org3
 *  chaincode 准备两份，不限内容和版本，用于测试

##### 步骤说明 #####

1 crypto-config.yaml文件生成安全证书  
2 configtx.yaml文件生成创始块和**多份**频道认证文件  
3 启动容器  
4 在cli客户端进行操作

##### 具体实现 #####

mkdir fabric/fabrictest  
cd fabrictest  
mkdir -p chaincode/go/channel\_one  
mkdir -p chaincode/go/channel\_two  
将准备的chaincode.go文件放入channel\_one和channel\_two文件夹中。

###### （1）crypto-config.yaml ######

OrdererOrgs:
      - Name: Orderer
        Domain: example.com
        Specs:
          - Hostname: orderer
    PeerOrgs:
      - Name: Org1
        Domain: org1.example.com
        Template:
          Count: 1
        Users:
          Count: 1
      - Name: Org2
        Domain: org2.example.com
        Template:
          Count: 1
        Users:
          Count: 1
      - Name: Org3
        Domain: org3.example.com
        Template:
          Count: 1
        Users:
          Count: 1

执行命令生成安全文件：

cryptogen generate --config=./crypto-config.yaml
    
    # 返回信息
    org1.example.com
    org2.example.com
    org3.example.com

注意，ca 服务中在 fabric-ca-server-config 后面有一个很长的文件名，以 \_sk 结尾，这个需要根据自己的情况修改，到自己的 crypto-config/peerOrganizations/org1.example.com/ca/ 文件夹下查看实际的文件名，修改上面的配置文件，共有两处。

# 加入channel
    peer channel join -b channelone.block
    
    # 安装 chaincode
    peer chaincode install -n channeltwo -p github.com/hyperledger/fabric/fabrictest/chaincode/go/chaincode_two -v 1.0

这样，就创建好了一个2个channel，3个Orgs的单机fabric网络，并且安装实例化了2个channel的链码。
