fabric學習筆記---手動建立fabric測試網絡(轉)

原文見 深刻理解Fabric環境搭建的詳細過程 http://www.cnblogs.com/studyzy/p/7451276.html 深藍居html

一、生成cryptogen(密碼生成器)node

咱們將使用cryptogen工具爲咱們生成各類網絡實體的加密材料(x509證書)。這些證書是身份的表明,它們容許在咱們的網絡實體進行交流和交易時進行簽名/驗證身份驗證。git

Fabric中有兩種類型的公私鑰和證書,一種是給節點以前通信安全而準備的TLS證書,另外一種是用戶登陸和權限控制的用戶證書。這些證書原本應該是由CA來頒發,可是咱們這裏是測試環境,並無啓用CA節點,因此Fabric幫咱們提供了一個工具:cryptogen。github

cd  /root/go/src/github.com/hyperledger/fabric
make cryptogen

結果以下:算法

build/bin/cryptogen
CGO_CFLAGS=" " GOBIN=/root/go/src/github.com/hyperledger/fabric/build/bin go install -tags "" -ldflags "-X github.com/hyperledger/fabric/common/tools/cryptogen/metadata.Version=1.0.0" github.com/hyperledger/fabric/common/tools/cryptogen
Binary available as build/bin/cryptogen

即 在./build/bin/cryptogen下生成了可執行程序cryptogendocker

二、配置網絡拓撲 crypto-config.yamlubuntu

examples/e2e_cli/crypto-config.yaml已經提供了一個Orderer Org和兩個Peer Org的配置,該模板中也對字段進行了註釋。咱們能夠把Org2拿來分析一下:安全

- Name: Org2 
  Domain: org2.example.com 
  Template: 
    Count: 2 
  Users: 
    Count: 1

Name和Domain就是關於這個組織的名字和域名,這主要是用於生成證書的時候,證書內會包含該信息。而Template Count=2是說咱們要生成2套公私鑰和證書,一套是peer0.org2的,還有一套是peer1.org2的。最後Users. Count=1是說每一個Template下面會有幾個普通User(注意,Admin是Admin,不包含在這個計數中),這裏配置了1,也就是說咱們只須要一個普通用戶User1@org2.example.com 咱們能夠根據實際須要調整這個配置文件,增刪Org Users等。bash

三、使用加密生成器 cryptogen 根據網絡拓撲 crypto-config.yaml生成相應證書網絡

cd examples/e2e_cli/
../../build/bin/cryptogen generate --config=./crypto-config.yaml

生成的文件都保存到crypto-config

                    ├── server.crt
                    └── server.key

四、編譯生成 交易生成器configtxgen

cd ~/go/src/github.com/hyperledger/fabric

make configtxgen

運行後的結果爲:

build/bin/configtxgen 
CGO_CFLAGS=" " GOBIN=/home/studyzy/go/src/github.com/hyperledger/fabric/build/bin go install -tags "nopkcs11" -ldflags "-X github.com/hyperledger/fabric/common/configtx/tool/configtxgen/metadata.Version=1.0.0" github.com/hyperledger/fabric/common/configtx/tool/configtxgen 
Binary available as build/bin/configtxgen

五、配置configtx.yaml

官方提供的examples/e2e_cli/configtx.yaml這個文件裏面配置了由2個Org參與的Orderer共識配置TwoOrgsOrdererGenesis,以及由2個Org參與的Channel配置:TwoOrgsChannel。Orderer能夠設置共識的算法是Solo仍是Kafka,以及共識時區塊大小,超時時間等,咱們使用默認值便可,不用更改。而Peer節點的配置包含了MSP的配置,錨節點的配置。若是咱們有更多的Org,或者有更多的Channel,那麼就能夠根據模板進行對應的修改。

六、經過交易生成器configtxgen生成區塊

(1)生成創世區塊

配置修改好後,咱們就用configtxgen 生成創世區塊。並把這個區塊保存到本地channel-artifacts文件夾中:

cd examples/e2e_cli/

../../build/bin/configtxgen -profile TwoOrgsOrdererGenesis -outputBlock ./channel-artifacts/genesis.block

(2)生成channel區塊

../../build/bin/configtxgen -profile TwoOrgsChannel -outputCreateChannelTx ./channel-artifacts/channel.tx -channelID mychannel

另外關於錨節點的更新,咱們也須要使用這個程序來生成文件:

../../build/bin/configtxgen -profile TwoOrgsChannel -outputAnchorPeersUpdate ./channel-artifacts/Org1MSPanchors.tx -channelID mychannel -asOrg Org1MSP

../../build/bin/configtxgen -profile TwoOrgsChannel -outputAnchorPeersUpdate ./channel-artifacts/Org2MSPanchors.tx -channelID mychannel -asOrg Org2MSP

最終,咱們在channel-artifacts文件夾中,應該是可以看到4個文件。

root@ubuntu:~/go/src/github.com/hyperledger/fabric/examples/e2e_cli# tree channel-artifacts/
channel-artifacts/
├── channel.tx
├── genesis.block
├── Org1MSPanchors.tx
└── Org2MSPanchors.tx

七、配置Fabric環境的docker-compose文件

(1)配置Orderer

Orderer的配置是在base/docker-compose-base.yaml裏

version: '2'

services:

  orderer.example.com:
    container_name: orderer.example.com
    image: hyperledger/fabric-orderer
    environment:
      - ORDERER_GENERAL_LOGLEVEL=debug
      - ORDERER_GENERAL_LISTENADDRESS=0.0.0.0
      - ORDERER_GENERAL_GENESISMETHOD=file
      - ORDERER_GENERAL_GENESISFILE=/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]
    working_dir: /opt/gopath/src/github.com/hyperledger/fabric
    command: orderer
    volumes:
    - ../channel-artifacts/genesis.block:/var/hyperledger/orderer/orderer.genesis.block
    - ../crypto-config/ordererOrganizations/example.com/orderers/orderer.example.com/msp:/var/hyperledger/orderer/msp
    - ../crypto-config/ordererOrganizations/example.com/orderers/orderer.example.com/tls/:/var/hyperledger/orderer/tls
    ports:
      - 7050:7050

這裏主要關心的是,ORDERER_GENERAL_GENESISFILE=/var/hyperledger/orderer/orderer.genesis.block,而這個創世區塊就是咱們以前建立的創世區塊,這裏就是Host到Docker的映射:

- ../channel-artifacts/genesis.block:/var/hyperledger/orderer/orderer.genesis.block

另外的配置主要是TL,Log等,最後暴露出服務端口7050。、

(2)配置peer

Peer的配置是在base/docker-compose-base.yaml和peer-base.yaml裏

docker-compose-base.yaml中截取peer0.org1.example.com配置

peer0.org1.example.com:
    container_name: peer0.org1.example.com
    extends:
      file: peer-base.yaml
      service: peer-base
    environment:
      - CORE_PEER_ID=peer0.org1.example.com
      - CORE_PEER_ADDRESS=peer0.org1.example.com:7051
      - CORE_PEER_CHAINCODELISTENADDRESS=peer0.org1.example.com:7052
      - CORE_PEER_GOSSIP_EXTERNALENDPOINT=peer0.org1.example.com:7051
      - CORE_PEER_LOCALMSPID=Org1MSP
    volumes:
        - /var/run/:/host/var/run/
        - ../crypto-config/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/msp:/etc/hyperledger/fabric/msp
        - ../crypto-config/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls:/etc/hyperledger/fabric/tls
    ports:
      - 7051:7051
      - 7052:7052
      - 7053:7053

peer-base.yaml

version: '2'
services:
  peer-base:
    image: hyperledger/fabric-peer
    environment:
      - CORE_VM_ENDPOINT=unix:///host/var/run/docker.sock
      # the following setting starts chaincode containers on the same
      # bridge network as the peers
      # https://docs.docker.com/compose/networking/
      - CORE_VM_DOCKER_HOSTCONFIG_NETWORKMODE=e2ecli_default

(3)配置CLI

CLI在整個Fabric網絡中扮演客戶端的角色,咱們在開發測試的時候能夠用CLI來代替SDK,執行各類SDK能執行的操做。CLI會和Peer相連,把指令發送給對應的Peer執行。CLI的配置在docker-compose-cli.yaml中

      - peer1.org1.example.com
      - peer0.org2.example.com
      - peer1.org2.example.com

從這裏咱們能夠看到,CLI啓動的時候默認鏈接的是peer0.org1.example.com,而且啓用了TLS。默認是以Admin@org1.example.com這個身份鏈接到Peer的。CLI啓動的時候,會去執行./scripts/script.sh 腳本,這個腳本也就是fabric/examples/e2e_cli/scripts/script.sh 這個腳本,這個腳本完成了Fabric環境的初始化和ChainCode的安裝及運行,也就是接下來要講的步驟4和5.在文件映射配置上,咱們注意到../chaincode/go/:/opt/gopath/src/github.com/hyperledger/fabric/examples/chaincode/go,也就是說咱們要安裝的ChainCode都是在fabric/examples/chaincode/go目錄下,之後咱們要開發本身的ChainCode,只須要把咱們的代碼複製到該目錄便可。

八、初始化fabric環境

(1)啓動Fabric環境的容器

咱們將整個Fabric Docker環境的配置放在docker-compose-cli.yaml後,只須要使用如下命令便可:

docker-compose -f docker-compose-cli.yaml up -d

最後這個-d參數若是不加,那麼當前終端就會一直附加在docker-compose上,而若是加上的話,那麼docker容器就在後臺運行。運行docker ps命令能夠看啓動的結果:1Orderer+4Peer+1CLI

CONTAINER ID        IMAGE                        COMMAND             CREATED             STATUS              PORTS                                                                       NAMES

(2)建立Channel

如今咱們要進入cli容器內部,在裏面建立Channel。先用如下命令進入CLI內部Bash:

docker exec -it cli bash

建立Channel的命令是peer channel create,咱們前面建立2.4建立Channel的配置區塊時,指定了Channel的名字是mychannel,那麼這裏咱們必須建立一樣名字的Channel。

ORDERER_CA=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem

peer channel create -o orderer.example.com:7050 -c mychannel -f ./channel-artifacts/channel.tx --tls true --cafile $ORDERER_CA

執行該命令後,系統會提示:

2017-08-29 20:36:47.486 UTC [channelCmd] readBlock -> DEBU 020 Received block:0

系統會在cli內部的當前目錄建立一個mychannel.block文件,這個文件很是重要,接下來其餘節點要加入這個Channel就必須使用這個文件。

(3)各個Peer加入Channel

前面說過,咱們CLI默認鏈接的是peer0.org1,那麼咱們要將這個Peer加入mychannel就很簡單,只須要運行以下命令:

peer channel join -b mychannel.block

系統返回消息:

2017-08-29 20:40:27.053 UTC [channelCmd] executeJoin -> INFO 006 Peer joined the channel!

那麼其餘幾個Peer又該怎麼加入Channel呢?這裏就須要修改CLI的環境變量,使其指向另外的Peer。好比咱們要把peer1.org1加入mychannel,那麼命令是:

複製代碼
CORE_PEER_LOCALMSPID="Org1MSP" 
CORE_PEER_TLS_ROOTCERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt 
CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/users/Admin@org1.example.com/msp 
CORE_PEER_ADDRESS=peer1.org1.example.com:7051

peer channel join -b mychannel.block
複製代碼

系統會返回成功加入Channel的消息。

一樣的方法,將peer0.org2加入mychannel:

複製代碼
CORE_PEER_LOCALMSPID="Org2MSP" 
CORE_PEER_TLS_ROOTCERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt 
CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/users/Admin@org2.example.com/msp 
CORE_PEER_ADDRESS=peer0.org2.example.com:7051

peer channel join -b mychannel.block
複製代碼

最後把peer1.org2加入mychannel:

複製代碼
CORE_PEER_LOCALMSPID="Org2MSP" 
CORE_PEER_TLS_ROOTCERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/peers/peer1.org2.example.com/tls/ca.crt 
CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/users/Admin@org2.example.com/msp 
CORE_PEER_ADDRESS=peer1.org2.example.com:7051

peer channel join -b mychannel.block
複製代碼

(4)更新錨節點

關於AnchorPeer,我理解的不夠深入,通過個人測試,即便沒有設置錨節點的狀況下,整個Fabric網絡仍然是能正常運行的。

對於Org1來講,peer0.org1是錨節點,咱們須要鏈接上它並更新錨節點:

複製代碼
CORE_PEER_LOCALMSPID="Org1MSP" 
CORE_PEER_TLS_ROOTCERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt 
CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/users/Admin@org1.example.com/msp 
CORE_PEER_ADDRESS=peer0.org1.example.com:7051

peer channel update -o orderer.example.com:7050 -c mychannel -f ./channel-artifacts/Org1MSPanchors.tx --tls true --cafile $ORDERER_CA
複製代碼

另外對於Org2,peer0.org2是錨節點,對應的更新代碼是:

CORE_PEER_LOCALMSPID="Org2MSP" 
CORE_PEER_TLS_ROOTCERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt 
CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/users/Admin@org2.example.com/msp 
CORE_PEER_ADDRESS=peer0.org2.example.com:7051

peer channel update -o orderer.example.com:7050 -c mychannel -f ./channel-artifacts/Org2MSPanchors.tx --tls true --cafile $ORDERER_CA

以上,整個Fabric網絡和Channel都準備完畢,接下來咱們來安裝和運行ChainCode。這裏仍然以最出名的Example02爲例。這個例子實現了a,b兩個帳戶,相互之間能夠轉帳。

九、鏈上代碼的安裝與運行

(1)Install ChainCode安裝鏈上代碼

鏈上代碼的安裝須要在各個相關的Peer上進行,對於咱們如今這種Fabric網絡,若是4個Peer都想對Example02進行操做,那麼就須要安裝4次。

仍然是保持在CLI的命令行下,咱們先切換到peer0.org1這個節點:

CORE_PEER_LOCALMSPID="Org1MSP" 
CORE_PEER_TLS_ROOTCERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt 
CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/users/Admin@org1.example.com/msp 
CORE_PEER_ADDRESS=peer0.org1.example.com:7051

使用peer chaincode install命令能夠安裝指定的ChainCode並對其命名:

peer chaincode install -n mycc -v 1.0 -p github.com/hyperledger/fabric/examples/chaincode/go/chaincode_example02

安裝的過程其實就是對CLI中指定的代碼進行編譯打包,並把打包好的文件發送到Peer,等待接下來的實例化。

其餘節點因爲暫時還沒使用到,咱們能夠先不安裝,等到了步驟5.4的時候再安裝。

(2)Instantiate ChainCode實例化鏈上代碼

實例化鏈上代碼主要是在Peer所在的機器上對前面安裝好的鏈上代碼進行包裝,生成對應Channel的Docker鏡像和Docker容器。而且在實例化時咱們能夠指定背書策略。咱們運行如下命令完成實例化:

peer chaincode instantiate -o orderer.example.com:7050 --tls true --cafile $ORDERER_CA -C mychannel -n mycc -v 1.0 -c '{"Args":["init","a","100","b","200"]}' -P "OR      ('Org1MSP.member','Org2MSP.member')"

若是咱們新開一個Ubuntu終端,去查看peer0.org1上的日誌,那麼就能夠知道整個實例化的過程到底幹了什麼:

docker logs -f peer0.org1.example.com

主要幾行重要的日誌:

複製代碼
2017-08-29 21:14:12.290 UTC [chaincode-platform] generateDockerfile -> DEBU 3fd

複製代碼

接下來的日誌就是各類初始化,驗證,寫帳本之類的。總之完畢後,咱們回到Ubuntu終端,使用docker ps能夠看到有新的容器正在運行:

CONTAINER ID        IMAGE                                 COMMAND                  CREATED             STATUS              PORTS                                                                       NAMES

(3)在一個Peer上查詢併發起交易

如今鏈上代碼的實例也有了,而且在實例化的時候指定了a帳戶100,b帳戶200,咱們能夠試着調用ChainCode的查詢代碼,驗證一下,在cli容器內執行:

peer chaincode query -C mychannel -n mycc -c '{"Args":["query","a"]}'

返回結果:Query Result: 100

接下來咱們能夠試着把a帳戶的10元轉給b。對應的代碼:

peer chaincode invoke -o orderer.example.com:7050  --tls true --cafile $ORDERER_CA -C mychannel -n mycc -c '{"Args":["invoke","a","b","10"]}'

(4)在另外一個節點上查詢交易

前面的操做都是在org1下面作的,那麼處於同一個區塊鏈(同一個Channel下)的org2,是否會看org1的更改呢?咱們試着給peer0.org2安裝鏈上代碼:

複製代碼
CORE_PEER_LOCALMSPID="Org2MSP" 
CORE_PEER_TLS_ROOTCERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt 
CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/users/Admin@org2.example.com/msp 
CORE_PEER_ADDRESS=peer0.org2.example.com:7051

peer chaincode install -n mycc -v 1.0 -p github.com/hyperledger/fabric/examples/chaincode/go/chaincode_example02
複製代碼

因爲mycc已經在前面org1的時候實例化了,也就是說對應的區塊已經生成了,因此在org2不能再次初始化。咱們直接運行查詢命令:

peer chaincode query -C mychannel -n mycc -c '{"Args":["query","a"]}'

返回結果:

Query Result: 90

這是由於peer0.org2也須要生成Docker鏡像,建立對應的容器,才能經過容器返回結果。咱們回到Ubuntu終端,執行docker ps,能夠看到又多了一個容器:

CONTAINER ID        IMAGE                                 COMMAND                  CREATED              STATUS              PORTS                                                                       NAMES
