fabric-samples-1.4.0 開發搭建

一、環境安裝前準備：

（1）首先安裝基本工具

yum install git
yum install curl
yum -y install epel-release
yum install python-pip
pip install --upgrade pip

（2）安裝Docker，安裝好後可以確認Docker和Docker Compose的版本：

docker --version
docker-compose --version

（2）安裝Go語言

# go 環境變數
export PATH=
 
$PATH:/usr/local/go/bin
export GOROOT=/usr/local/go
export GOPATH=$HOME/go
export PATH=$PATH:$HOME/go/bin
# go 版本
go version

（3）安裝Node.js

yum install gcc gcc-c++
gcc -v

4.8.5版本過低，若已為最新版請跳過至步驟，升級gcc，前往http://ftp.gnu.org/gnu/gcc/下載你想要的版本

wget http://ftp.gnu.org/gnu/gcc/gcc-8.2.0/gcc-8.2.0.tar.gz
tar -C /usr/local -xzf gcc-
 
8.2.0.tar.gz
cd /usr/local/gcc-8.2.0
./contrib/download_prerequisites  
mkdir build  
cd build  
../configure -enable-checking=release -enable-languages=c,c++ disable-multilib  
yum groupinstall "Development Tools" 
make           #需要很長時間
make install 
reboot           #重啟

（4）繼續安裝nodejs

node -v

（5）安裝 npm

npm install npm -g
npm -v

二、 下載fabric-samples原始碼

（1）git clone https://github.com/hyperledger/fabric-samples.git
（2）目前官網預設是 1.3 版本需要修改配置檔案

注意：需要安裝二進位制可執行檔案 和配置檔案，可以提前下載好二進位制檔案上傳到
/root/go/src/github.com/hyperledger/fabric-samples 下
下載地址：https://download.csdn.net/download/liruizi/10849641

#進入 scripts 目錄
/root/go/src/github.com/hyperledger/fabric-samples/scripts
[[email protected] scripts]# vi bootstrap.sh 

三、想要現在執行嗎

fabric提供一個完全註釋的指令碼byfn.sh，利用這些Docker映象可以快速引導一個由4個代表2個不同組織的peer節點以及一個排序服務節點的Hyperledger fabric網路。它還將啟動一個容器來執行一個將peer節點加入channel、部署例項化鏈碼服務以及驅動已經部署的鏈碼執行交易的指令碼。

以下是該byfn.sh指令碼的幫助文件：

./byfn.sh -h
Usage:
  byfn.sh -m up|down|restart|generate [-c <channel name>] [-t <timeout>]
  byfn.sh -h|--help (print this message)
    -m <mode> - one of 'up', 'down', 'restart' or 'generate'
      - 'up' - bring up the network with docker-compose up
      - 'down' - bring up the network with docker-compose up
      - 'restart' - bring up the network with docker-compose up
      - 'generate' - generate required certificates and genesis block
    -c <channel name> - config name to use (defaults to "mychannel")
    -t <timeout> - CLI timeout duration in microseconds (defaults to 10000)

Typically, one would first generate the required certificates and
genesis block, then bring up the network. e.g.:

  byfn.sh -m generate -c <channelname>
  byfn.sh -m up -c <channelname>

如果你選擇不提供channel名稱，則指令碼將使用預設名稱mychannel。CLI超時引數（用-t標誌指定）是一個可選值;如果你選擇不設定它，那麼CLI容器將會在指令碼執行完之後退出。

生成網路神器

準備好了嗎？好吧！執行以下命令。你將會看到會發生什麼伴隨yes/no命令列提示的簡要說明。輸入y來執行描述的動作。

./byfn.sh -m generate
Generating certs and genesis block for channel 'mychannel' with CLI timeout of '10' seconds and CLI delay of '3' seconds
Continue? [Y/n] y
