hyperledger fabric 网络操作基本操作和概念

hyperledger fabric 网络操作基本操作和概念

在搭建好hyperledger fabric环境后，继续进行网络搭建操作
新建文件夹twonodes（与github.com同级）

1. cryptogen 操作

1.1 cryptogen 生成证书文件

1.1.1 生成证书文件模板

# 打印模板到终端
cryptogen showtemplate
# 打印模板到配置文件crypto-config.yaml
cryptogen showtemplate > crypto-config.yaml

生成模板配置文件说明

1.1.1.1 排序节点OrdererOrgs配置

OrdererOrgs:
  - Name: Orderer # 排序节点名称
    Domain: example.com # 排序节点域名
    EnableNodeOUs: false # 是否使用OU配置(OU表示组织单元即每个组织下面很多节点，可以将一些节点作为一个部门)
    # "Specs" - See PeerOrgs below for complete description
    Specs:
      - Hostname: orderer

1.1.1.2 普通节点PeerOrgs配置

PeerOrgs:
  # Org1 组织1
  - Name: Org1 #组织1名称
    Domain: org1.example.com #组织1域名
    EnableNodeOUs: true

1.1.1.3 Template 配置

Template:
      Count: 1 # 组织节点个数，节点名称顺序排列
      # Start: 5
      # Hostname: .Prefix.Index # default
      # SANS:
      #   - ".Hostname.alt..Domain"

    #

1.1.1.4 Users用户配置

(user和peer区别，user可以理解为终端，指人，而peer是节点，只是一台运行的机器或集群的一个节点)

    # "Users"
    # Count: The number of user accounts _in addition_ to Admin
    Users:
      Count: 1

1.1.1.5 crypto-config.yaml

Order组织节点定义

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

PeerOrgs:
  # ---------------------------------------------------------------------------
  # Org1
  # ---------------------------------------------------------------------------
  - Name: Org1
    Domain: org1.trace.com
    Template:
      Count: 1
    Users:
      Count: 1
 # ---------------------------------------------------------------------------
  # Org2
  # ---------------------------------------------------------------------------
  - Name: Org2
    Domain: org2.trace.com
    Template:
      Count: 1
    Users:
      Count: 1
 # ---------------------------------------------------------------------------
  # Org3
  # ---------------------------------------------------------------------------
  - Name: Org3
    Domain: org3.trace.com
    Template:
      Count: 1
    Users:
      Count: 1
 # ---------------------------------------------------------------------------
  # Org4
  # ---------------------------------------------------------------------------
  - Name: Org4
    Domain: org4.trace.com
    Template:
      Count: 1
    Users:
      Count: 1

# ---------------------------------------------------------------------------
  # Org5
  # ---------------------------------------------------------------------------
  - Name: Org5
    Domain: org5.trace.com
    Template:
      Count: 1
    Users:
      Count: 1

1.1.2 生成密钥材料

cryptogen generate --config=crypto-config.yaml

1.2 cryptogen.yaml 创建通道配置

拷贝/hyperledger/fabric-samples/test-network/configtx/configx.yaml 到目录下
修改msp配置文件（成员服务提供者 (MSP)及相关证书配置
因为Fabric是一个认证性的网络, 所以区块链参与者需要一种向网络中的其他参与者证实自己身份的机制从而在网络中进行交易
证书机构通过生成可以用来证实身份的由公钥和私钥形成的键值对来发放认证信息。因为一个私钥永远不会被公开，所以引入了一种可以证实身份的机制即MSP。例如，一个peer节点用它的私钥进行数字签名或背书交易。接着排序节点包含的该peer节点的公钥会被用来验证交易携带的签名是否合法。私钥被用作生成交易信息上的，只有与私钥相对应的且作为MSP一部分的公钥可以匹配的签名。因此，MSP是一个可让身份被信任和被网络中其他参与者公认的，而不需要暴露成员的私钥的机制。

#   SECTION: Capabilities
#
#   - This section defines the capabilities of fabric network. This is a new
#   concept as of v1.1.0 and should not be utilized in mixed networks with
#   v1.0.x peers and orderers.  Capabilities define features which must be
#   present in a fabric binary for that binary to safely participate in the
#   fabric network.  For instance, if a new MSP type is added, newer binaries
#   might recognize and validate the signatures from this type, while older
#   binaries without this support would be unable to validate those
#   transactions.  This could lead to different versions of the fabric binaries
#   having different world states.  Instead, defining a capability for a channel
#   informs those binaries without this capability that they must cease
#   processing transactions until they have been upgraded.  For v1.0.x if any
#   capabilities are defined (including a map with all capabilities turned off)
#   then the v1.0.x peer will deliberately crash.

3 问题解决记录

问题解决：

Error: error getting endorser client for channel: endorser client failed to connect to peer0.org1.trace.com:7051: failed to create new connection: connection error: desc = "transport: error while dialing: dial tcp 172.22.0.7:7051: connect: connection refused"

Error: error getting endorser client for channel: endorser client failed to connect to peer0.org1.trace.com:7051: failed to create new connection: context deadline exceeded

解决方法：

sudo vi /etc/resolv.conf

按:wq!退出

4 启动区块链docker节点

4.1 常用docker命令

删除所有容器

# 1.停用全部运行中的容器:
docker stop $(docker ps -q)
# 2.删除全部容器：
docker rm $(docker ps -aq)

删除所有镜像

docker rmi -f $(docker images -qa)

删除数据卷

# 删除数据卷:
docker volume rm $(docker volume ls -q)
# 删除 network:
docker network rm $(docker network ls -q)

一键执行

docker stop $(docker ps -q)
docker rm $(docker ps -aq)
docker volume rm $(docker volume ls -q)
./start.sh

5 fabric-node-sdk后台搭建

nodejs 后台搭建（在ubuntu 阿里云服务器）
安装nvm

wget -qO- https://raw.githubusercontent.com/creationix/nvm/v0.31.1/install.sh | bash

执行

source ~/.bashrc

下载node依赖

nvm install 12.13.1
rm -rf node_modules
rm -rf hfc-key-store
nvm use 12.13.1
npm install
nvm use 12.13.1
npm rebuild
npm install fabric-client
npm install fabric-ca-client
node enrollAdmin.js
node registerUser.js
npm install express
npm install body-parser
npm install influx

npm install forever -g
forever start app.js
