系統環境：
[root@localhost ~]# cat /proc/version
Linux version 3.10.0-1160.el7.x86_64 (mockbuild@kbuilder.bsys.centos.org) (gcc version 4.8.5 20150623 (Red Hat 4.8.5-44) (GCC) ) #1 SMP Mon Oct 19 16:18:59 UTC 2020

環境搭建
一、基礎軟體安裝
# 安裝Git(Git是一個免費的、開源的分布式版本控制系統)
# https://git-scm.com/downloads
[root@localhost ~]# yum install git
# 驗證
[root@localhost ~]# git version
git version 1.8.3.1
安裝cURL
cURL是一個利用URL語法在命令列下作業的檔案傳輸工具,它支持檔案上傳和下載，所以是綜合傳輸工具
# https://curl.haxx.se/download.html
[root@localhost ~]# yum install curl
# 驗證
[root@localhost ~]# curl --version
curl 7.29.0 (x86_64-redhat-linux-gnu) libcurl/7.29.0 NSS/3.53.1 zlib/1.2.7 libidn/1.28 libssh2/1.8.0
Protocols: dict file ftp ftps gopher http https imap imaps ldap ldaps pop3 pop3s rtsp scp sftp smtp smtps telnet tftp
Features: AsynchDNS GSS-Negotiate IDN IPv6 Largefile NTLM NTLM_WB SSL libz unix-sockets
安裝Docker（Docker Engine）
Docker 是一個開源的應用容器引擎，讓開發者可以打包他們的應用以及依賴包到一個可移植的鏡像中，然后發布到任何流行的 Linux或Windows 機器上，也可以實作虛擬化
# https://docs.docker.com/get-docker/
Docker引擎（Docker Engine）安裝請參考該教程：https://blog.csdn.net/Bjxhub/article/details/119352882
# 關鍵命令
[root@localhost ~]# sudo yum install docker-ce docker-ce-cli containerd.io
# 確認安裝后的docker版本
[root@localhost ~]# docker --version
Docker version 20.10.7, build f0df350
# Docker Compose 依賴 Docker Engine 進行任何有意義的作業，因此請確保根據您的設定，在本地或遠程安裝了 Docker Engine，
# 使用 Docker Compose 可以輕松、高效的管理容器，它是一個用于定義和運行多容器 Docker 的應用程式工具
Docker Compose安裝官方教程：https://docs.docker.com/compose/install/
# 下載docker-compose，建議關閉防火墻,否則報錯：curl: (35) Encountered end of file
[root@localhost ~]# systemctl stop firewalld
[root@localhost ~]#
sudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
# 賦權
[root@localhost ~]# sudo chmod +x /usr/local/bin/docker-compose
# 驗證
[root@localhost ~]# docker-compose --version
docker-compose version 1.29.2, build 5becea4c
#Docker引擎（Docker Engine）與Docker Compose的版本（此處均取最新）對應關系：
https://docs.docker.com/compose/compose-file/compose-versioning/
# 啟動
[root@localhost ~]# sudo systemctl start docker
# 開機啟動
[root@localhost ~]# sudo systemctl enable docker
安裝Go
Google 的 Robert Griesemer，Rob Pike 及 Ken Thompson 開發的一種靜態強型別、編譯型語言
##！！！！----若Go與Jq無法安裝，則需添加安裝源:[[root@localhost ~]# yum install epel-release]----！！！！！
# https://golang.org/doc/install（國內無法訪問）
[root@localhost ~]# yum install go
# 驗證
[root@localhost ~]# go version
go version go1.15.5 linux/amd64
安裝JQ
jq是一個輕量級且靈活的命令列JSON處理器
# https://stedolan.github.io/jq/download/
[root@localhost ~]# yum install jq
# 驗證
[root@localhost ~]# jq --version
jq-1.6
二、 安裝 Fabric 和 Fabric 示例
2.1 自動搭建（不推薦，國內基本不成功，推薦直接進入2.2 手動搭建）
# 創建一個作業目錄并進入
[root@localhost ~]# mkdir -p mkdir -p $HOME/go/src/github.com/fabric
[root@localhost ~]# cd $HOME/go/src/github.com/fabric
# 查看當前全路徑
[root@localhost fabric]# pwd
/root/go/src/github.com/fabric
# 方式一： 執行自動搭建腳本(不推薦)
# !!!!自動下載最新版本的 Fabric 示例、docker 鏡像和二進制檔案，!!!!
[root@localhost fabric]# curl -sSL https://bit.ly/2ysbOFE | bash -s
# 方式二： 更換腳本地址再執行(不推薦)
若上述命令報錯：curl: (35) Encountered end of file
原因：命令中的https://bit.ly/2ysbOFE在國內無法訪問，
官方給出了可在國內可訪問的新地址：https://raw.githubusercontent.com/hyperledger/fabric/main/scripts/bootstrap.sh
解決方案：執行如下自動搭建命令（需要一個漫長的等待~）
[root@localhost fabric]# curl -sSL https://raw.githubusercontent.com/hyperledger/fabric/main/scripts/bootstrap.sh| bash -s

2.2 手動搭建搭建（推薦）
Step1、下載fabric原始碼
# 進入之前創建的作業目錄
[root@localhost ~]# cd $HOME/go/src/github.com/fabric
# ！！不推薦該獲取方式
[root@localhost fabric]# git clone https://github.com/hyperledger/fabric.git
# 注意：這一步下載會很慢，可以使用科學上網方法
# 也可以使用Chrome瀏覽器中GitHub加速插件，下面使用加速插件連接替換
# ！！！！推薦以下獲取方式：
# 以下代碼執行其中一行即可，
git clone https://hub.fastgit.org/hyperledger/fabric.git
# or
git clone https://github.com.cnpmjs.org/hyperledger/fabric.git
# or
git clone https://github.91chifun.workers.dev//https://github.com/hyperledger/fabric.git
Step2、下載Docker鏡像
[root@localhost fabric]# cd fabric/scripts/
[root@localhost scripts]# sudo ./bootstrap.sh -b -s
......

[root@localhost opt]# ls
containerd hyperledger-fabric-ca-linux-amd64-1.5.0.tar.gz hyperledger-fabric-linux-amd64-2.3.2.tar.gz
# 解壓（兩個壓縮檔案解壓出 bin/ config/ 兩個目錄，兩個目錄應位于fabric-samples之下~）

三、 啟動測驗網路
# 進入test-network目錄
[root@localhost test-network]# cd $HOME/go/src/github.com/fabric/fabric/scripts/fabric-samples/test-network
# 洗掉先前可能運行的網路

四、 創建頻道（channel）
# 默認 為mychannel，可以自定義channel名：./network.sh createChannel -c <自定義Channel名>
[root@localhost test-network]# ./network.sh createChannel
Creating channel 'mychannel'.
If network is not up, starting nodes with CLI timeout of '5' tries and CLI delay of '3' seconds and using database 'leveldb
Generating channel genesis block 'mychannel.block'
/root/go/src/github.com/fabric/fabric/scripts/fabric-samples/bin/configtxgen
.......
2021-08-05 05:31:24.428 UTC [channelCmd] InitCmdFactory -> INFO 001 Endorser and orderer connections initialized
2021-08-05 05:31:24.442 UTC [channelCmd] update -> INFO 002 Successfully submitted channel update
Anchor peer set for org 'Org2MSP' on channel 'mychannel'
Channel 'mychannel' joined
五、 啟用鏈碼（chaincode）
# 在啟用碼鏈前，需要更改go代理，確保啟用成功，
否則，會報如下錯誤：
......
Error: failed to normalize chaincode path: 'go list' failed with: : signal: killed
Chaincode packaging has failed
Deploying chaincode failed
[root@localhost test-network]# go env -w GOPROXY=https://goproxy.io,direct

# deployCC子命令將在peer0.org1.example.com和peer0.org2.example.com上安裝資產轉移（基本）鏈碼，然后在使用通道標志指定的通道上部署鏈碼（如果未指定通道，則在mychannel上部署），
