fabric环境安装,设置全局访问 -
手动组建Fabric网络
一:生成fabric证书
1.JPG
1.在根目录下,创建项目目录
mkdir testfabric
cd testfabric
2.模板内容重定向到指定文件中
#名字自己起, 叫什么都行, 一般叫: crypto-config.yaml (官方给的例子叫这个)
cryptogen showtemplate > crypto-config.yaml
3.配置文件的模板
vi crypto-config.yaml
OrdererOrgs:
- Name: Orderer # 1.排序节点组织的名字
Domain: itcast.com # 2.访问排序节点组织的域名, 测试网中随便写, 真实的网络, 需要注册
Specs:
- Hostname: orderer
# 3.其中以orderer节点的名字
# 4.得到了访问这个orderer节点的地址: orderer.itcast.com
PeerOrgs:
- Name: OrgGo # 6.当前组织的名字
Domain: orggo.itcast.com # 7.当前组织的根域名
EnableNodeOUs: true # 8.在msp目录会有一个config.yaml的配置文件
Template: # 使用模板生成peer节点的证书
Count: 2
# 9.使用模板生成2个peer节点的证书
# 10.访问域名: 第一个peer: peer0.orggo.itcast.com
# 11.访问域名: 第二个peer: peer1.orggo.itcast.com
Users:
Count: 3 # 12.生成3个普通用户账号, 和1个 管理员用户
- Name: OrgCpp
Domain: orgcpp.itcast.com
EnableNodeOUs: false
Template:
Count: 2
Users:
Count: 3
4.根据配置文件生成证书
cryptogen generate --config=crypto-config.yaml
# 在crypto-config文件夹中生成了一些账号:
1.JPG
5.锚节点
每个组织选择一个peer节点,代表当前组织和其他组织通信,这个节点叫锚节点,在配置文件中指定谁是锚节点,一个组织里,最多只能有一个锚节点
二:创始块文件和通道文件的生成
1.模板在什么地方?
(1)官方给的例子: first-network -> configtx.yaml
(2)找到这个文件之后, 不要改名字, 如果改名, 命令就加载不到这个配置文件了
(3)主要修改三部分内容:
- 配置组织信息
- orderer组织
- peer组织
- go
- cpp
- 配置 orderer节点的属性
- 如何生成一个区块
- 时间频率
- 块大小
- 消息条数
- 如何生成一个区块
- 对网络的总结:
- 如何生成创始区块文件
- 如何生成通道文件

#
# Specs is an array of Spec entries. Each Spec entry consists of two fields:
# - Hostname: (Required) The desired hostname, sans the domain.
# - CommonName: (Optional) Specifies the template or explicit override for
# the CN. By default, this is the template:
#
# "{{.Hostname}}.{{.Domain}}"
#
# which obtains its values from the Spec.Hostname and
# Org.Domain, respectively.
# - SANS: (Optional) Specifies one or more Subject Alternative Names
# to be set in the resulting x509. Accepts template
# variables {{.Hostname}}, {{.Domain}}, {{.CommonName}}. IP
# addresses provided here will be properly recognized. Other
# values will be taken as DNS names.
# NOTE: Two implicit entries are created for you:
# - {{ .CommonName }}

# 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.

4.通过命令生成创始区块和通道文件
(1).生成创始块文件
configtxgen -profile Genesis -outputBlock genesis.block
(2)生成通道文件
# -outputCreateChannelTx: 指定通道文件的名字
# -channelID : 指定要生成的通道的通道名字
# 如果没有通过该参数指定, 创建的通道有默认的名字: mychannel
configtxgen -profile Channel -outputCreateChannelTx channel.tx -channelID itcastchannel
(3)生成更新锚节点的文件
# 一般情况下不需要更新, 除非是要替换到现有的指定的锚节点
# 不同组织的锚节点更新数据放到不同的文件中
# -outputAnchorPeersUpdate: 指定锚节点文件的名字
# -asOrg: 组织的名字, configtx.yaml中组织的name中找
# 1.更新go组织的锚节点
configtxgen -profile Channel -outputAnchorPeersUpdate goAnchor.tx -channelID itcastchannel -asOrg OrgGoMSP
# 2.更新cpp组织的锚节点
configtxgen -profile Channel -outputAnchorPeersUpdate cppAnchor.tx -channelID itcastchannel -asOrg OrgCppMSP
5.启动节点
2个组织,每个组织有一个客户端,1个order,4个peer,一共7个docker
写docker-compose

启动
docker-compose -f docker-compose-cli.yaml up -d
docker-compose -f docker-compose-cli.yaml ps
容器启动之后:
客户端节点
peer节点
order节点
1.要创建通道
2.将所有的组织的所有结点,加入到创建的通道中
3.给所有的结点(peer)安装链码
4.不同组织的结点,链码是不一样的
5.初始化链码,在任意节点初始化一次,数据会自动同步到其他节点上
6.链码调用,读,写
创建通道
docker exec -it cli bash
tlsfile=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/itcast.com/tlsca/tlsca.itcast.com-cert.pem
peer channel create -o orderer.itcast.com:7050 --tls true --cafile $tlsfile -c itcastchannel -f ./channel-artifacts/channel.tx
加入通道:
peer channel join -b itcastchannel.block
链码安装:
peer chaincode install -n itcastcc -v 1.0 -p github.com/chaincode
链码的打包 -> 建议(多机多节点部署)
peer chaincode package -n itcastcc -v 1.0 -p github.com/chaincode chaincode.out
链码打包之后, 得到一个打包文件, 进行链码安装的时候可以使用这个文件直接进行链码安装
如何安装
$ peer chaincode install 文件名(对链码打包之后得到的文件)
tlsfile=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/itcast.com/orderers/orderer.itcast.com/msp/tlscacerts/tlsca.itcast.com-cert.pem
tlsfile -C itcastchannel -n itcastcc -v 1.0 -P "AND ('OrgGoMSP.member', 'OrgCppMSP.member')" -c '{"Args":["init", "a", "100", "b", "200"]}'
