1.?what-做什么
區(qū)塊鏈技術(shù)發(fā)展至今，形成了公有鏈、聯(lián)盟鏈和邦鏈三種種主流技術(shù)平臺(tái)。
公有鏈： 面向大眾，用戶可以匿名參與，非常方便，賬本數(shù)據(jù)也公開，加上強(qiáng)大的智能合約，因此公有鏈極大地促進(jìn)了區(qū)塊鏈概念和技術(shù)的普及，比如比特幣、Ethereum平臺(tái)等。
聯(lián)盟鏈： 考慮到商業(yè)應(yīng)用對(duì)安全、隱私、監(jiān)管、審計(jì)、性能的需求，提高準(zhǔn)入門檻，增加了安全、隱私、可監(jiān)管審計(jì)等商業(yè)特性，是區(qū)塊鏈技術(shù)在商業(yè)領(lǐng)域的應(yīng)用探索。
邦鏈：暫時(shí)資料比較少。
概念
通道（ Channel ）：通道是構(gòu)建在 Hyperledger Fabric 區(qū)塊鏈網(wǎng)絡(luò)上的私有區(qū)塊鏈，實(shí)現(xiàn)了數(shù)據(jù)的隔離和保密。通道中的 Chaincode 和交易只有加入該通道的節(jié)點(diǎn)（ Peer ）可見。同一個(gè)節(jié)點(diǎn)可以加入多個(gè)通道，并為每個(gè)通道內(nèi)容維護(hù)一個(gè)賬本。每一個(gè)通道即為一條邏輯上的區(qū)塊鏈。可以按照業(yè)務(wù)來(lái)劃分通道，也可以按照行政職能和隱私策略來(lái)劃分通道。
節(jié)點(diǎn)（ Peer ）： 維護(hù)賬本的網(wǎng)絡(luò)節(jié)點(diǎn)，通常區(qū)塊鏈網(wǎng)絡(luò)架構(gòu)中存在多種角色，如 endorser 和 committer 。
排序服務(wù)或共識(shí)服務(wù)（ Order Services ） ： 提供排序服務(wù)或共識(shí)服務(wù)的網(wǎng)絡(luò)節(jié)點(diǎn)，完成交易的排序和區(qū)塊打包等工作，支持可插拔的共識(shí)組件，當(dāng)前生產(chǎn)環(huán)境下使用 Kafka 進(jìn)行交易排序。
分布式賬本（ Distribute Ledger ） ：由網(wǎng)絡(luò)中若干去中心化節(jié)點(diǎn)共同維護(hù)的數(shù)據(jù)賬本。
組織（ Org ） ：聯(lián)盟鏈中按照 訪問(wèn)和使用賬本的網(wǎng)絡(luò)節(jié)點(diǎn)，一個(gè)聯(lián)盟（或者一個(gè)區(qū)塊鏈網(wǎng)絡(luò)）有多個(gè)組織（成員），一個(gè)組織內(nèi)可以有多個(gè)節(jié)點(diǎn)（ Peer ），每個(gè)節(jié)點(diǎn)參與賬本和世界狀態(tài)維護(hù)。
智能合約（ Smart Contract ） ：根據(jù)特定條件自動(dòng)執(zhí)行的合約程序。智能合約是區(qū)塊鏈的重要特征，是用戶與區(qū)塊鏈進(jìn)行交互，利用區(qū)塊鏈實(shí)現(xiàn)業(yè)務(wù)邏輯的重要途徑。
鏈碼（ Chaincode ）：鏈碼是 Hyperledger Fabric 對(duì)智能合約的一種實(shí)現(xiàn)方式，是運(yùn)行于 Hyperledger Fabric 網(wǎng)絡(luò)之上一段應(yīng)用程序代碼，也是用戶與 Hyperledger Fabric 交互的唯一途徑。
鏈（ Chain ）：一個(gè)鏈即是一個(gè)由若干區(qū)塊通過(guò)特定指向鏈接、摘要算法或加密算法錨定組成的數(shù)據(jù)集合。

yum -y install epel-release yum install -y git yum install -y golang2.2.?安裝Docker
curl -s https://raw.githubusercontent.com/oscm/shell/master/virtualization/docker/docker.centos7.ce.sh | bash curl -s https://raw.githubusercontent.com/oscm/shell/master/virtualization/docker/registry-mirror.sh | bash or curl -fsSL https://get.docker.com/ | sh 創(chuàng)建2個(gè)docker網(wǎng)絡(luò),如下： docker network create fabric_noops docker network create fabric_pbft安裝 docker-compose
curl -s https://raw.githubusercontent.com/oscm/shell/master/virtualization/docker/docker-compose.sh | bash2.3.?安裝 Node.js 環(huán)境
?
yum install -y nodejs npm install2.4.?安裝 hyperledger 1.0.4
運(yùn)行后 hyperledger 相關(guān)鏡像被安裝到 Docker 中
cd /usr/local/src curl -s https://raw.githubusercontent.com/hyperledger/fabric/release/scripts/bootstrap-1.0.4.sh | bash由于上面腳本會(huì)安裝所有節(jié)點(diǎn)，速度較慢，作者建議你參考下一章節(jié)，手工安裝所需最低配置節(jié)點(diǎn)。
2.5.?手工安裝 hyperledger v 1.0.5 開發(fā)環(huán)境
對(duì)于開發(fā)環(huán)境，最小化的環(huán)境，包括 1 個(gè) peer 節(jié)點(diǎn)、1 個(gè) Orderer 節(jié)點(diǎn)、1 個(gè) CA 節(jié)點(diǎn)。
準(zhǔn)備一個(gè)服務(wù)器或者虛擬機(jī)，安裝 CentOS 操作系統(tǒng)。
如果你是在已有的Docker上安裝，建議你刪除所有容器后在安裝。以免出現(xiàn)沖突等情況。
docker stop $(docker ps -q) && docker rm $(docker ps -aq)2.5.1.?登錄 docker

這里我們最小化啟動(dòng)，需要四個(gè)節(jié)點(diǎn)，分別是 ca, peer, order, couchdb。
