Hyperledger Fabric入門實戰（二）——環境搭建

1. Fabric環境搭建

準備工作

官方幫助文檔：https://hyperledger-fabric.readthedocs.io/en/release-1.2/

安裝 cURL(https://curl.haxx.se/download.html),curl --version 查詢版本

安裝docker，docker --version 查詢版本

安裝docker-compose,docker-compose --version 查詢版本

安裝 go 語言環境，go version 查詢版本

安裝node.js, node -v 查詢版本

Python 版本要求爲 2.7，python --version 查詢版本

1.1 安裝docker

基礎軟件安裝

# 安裝基本軟件
$ sudo apt-get update
$ sudo apt-get install apt-transport-https ca-certificates curl git software-properties-common lrzsz -y

添加阿里的docker鏡像倉庫

# 添加阿里的docker鏡像倉庫
$ curl -fsSL https://mirrors.aliyun.com/docker-ce/linux/ubuntu/gpg | sudo apt-key add -
$ sudo add-apt-repository "deb [arch=amd64] https://mirrors.aliyun.com/docker-ce/linux/ubuntu $(lsb_release -cs) stable"
# 更新軟件源
$ sudo apt-get update

安裝docker

# 安裝docker
$ sudo apt-get install docker-ce -y
# 查看安裝的docker版本
$ docker version
	Client:
         Version:           18.06.1-ce
         API version:       1.38
         Go version:        go1.10.3
         Git commit:        e68fc7a
         Built:             Tue Aug 21 17:24:51 2018
         OS/Arch:           linux/amd64
         Experimental:      false
    Got permission denied while trying to connect to the Docker daemon socket at
    unix:///var/run/docker.sock: Get
    http://%2Fvar%2Frun%2Fdocker.sock/v1.38/version: 
    dial unix /var/run/docker.sock: connect: `permission denied`
# 當前用戶直接操作docker時, 權限不夠, 需要做下面的第4不操作
#配置加速器
加速器網址 http://dashboard.daocloud.io/build-flows ，點擊小火箭， 複製一下linux代碼，然後將代碼在在Ubuntu的shell上運行
 注：進入  /etc/docker 修改damon.json裏的內容爲{"registry-mirrors": ["http://f1361db2.m.daocloud.io"],"insecure-registries":[]}
 重啓docker：
  sudo  systemctl restart docker

將當前用戶添加到docker組

# 將用戶加入該 group 內。然後退出並重新登錄就生效啦。
$ sudo gpasswd -a ${USER} docker
# 重啓docker服務
$ systemctl restart docker
# 當前用戶切換到docker羣組
$ newgrp - docker
$ docker version

         Version:           18.06.1-ce
         API version:       1.38
         Go version:        go1.10.3
         Git commit:        e68fc7a

    Server:
         Engine:
         Version:          18.06.1-ce
         API version:      1.38 (minimum version 1.12)

         OS/Arch:          linux/amd64
         Experimental:     false

安裝docker-compose

#安裝依賴工具
$ sudo apt-get install python-pip -y
#安裝編排工具
$ sudo pip install docker-compose
#查看版本
$ sudo docker-compose version

1.2 安裝go

# 1. 使用wget工具下載安裝包
$ wget https://dl.google.com/go/go1.11.linux-amd64.tar.gz
# 2. 解壓tar包到/usr/local
$ sudo tar zxvf go1.11.linux-amd64.tar.gz -C /usr/local
# 3. 創建Go目錄
$ mkdir $HOME/go
# 4. 用vi打開~./bashrc，配置環境變量
$ vim ~/.bashrc
# 5. 增加下面的環境變量，保存退出
	export GOROOT=/usr/local/go
    export GOPATH=$HOME/go
    export PATH=$PATH:$GOROOT/bin:$GOPATH/bin
# 6. 使環境變量立即生效, 一些命令二選一
$ source ~/.bashrc  
$ . ~/.bashrc
# 7. 檢測go是否安裝好
$ go version

1.3 安裝Node.js

下載二進制源碼包

$ wget https://nodejs.org/dist/v8.11.4/node-v8.11.4-linux-x64.tar.xz

解壓並安裝

# 指定壓縮包解壓到/opt目錄下
$ sudo tar xvf node-v8.11.4-linux-x64.tar.xz -C /opt
	- 在/opt目錄下得到 node-v8.11.4-linux-x64 目錄

將node.js設置爲全局可用

# 打開系統級別的配置文件 /etc/profile
$ sudo vim /etc/profile
# 添加如下配置項, 保存退出
    export NODEJS_HOME=/opt/node-v8.11.4-linux-x64
    export PATH=$PATH:$NODEJS_HOME/bin
# 重新加載配置文件
$ . /etc/profile
/etc/profile -> 設置環境變量的配置文件
	- 對當前系統下所有用戶生效

測試
```
$ node -v
```

1.4 部署hyperledger Fabric

下載並執行fabric的引導腳本bootstrap.sh
這個過程會很漫長很漫長… 快的話一兩個小時，慢的話一兩天 …

# 創建放置的目錄，然後進入該目錄，用curl下載腳本。
$ cd ~ # 這裏在家目錄下創建放置目錄
$ mkdir hyperledger-fabric # 創建放置目錄
$ cd hyperledger-fabric
# ***這裏本人電腦連接無線網無法下載，一直報錯，電腦要開vpn才能下載，但是按理說服務器上的網和本機的網應該沒有任何關係纔對，有些玄學... 建議電腦連接網線 try a try***
$ curl -sSL https://raw.githubusercontent.com/hyperledger/fabric/master/scripts/bootstrap.sh | bash -s 1.2.0 1.2.0 0.4.10
  #-s後面三個參數，分別爲：
  	- fabric: fabric的版本
	- fabric-ca: fabric-ca的版本
	- thirdparty: 第三方庫的版本
# 該腳本啓動之後會下載兩個壓縮包和一些鏡像文件, 整個過程會比較長, 耐心等待...
# 溫馨提示: 這個過程會讓你產生想要砸電腦的衝動, 控制好你的情緒!!!!
# 上述命令剛開始會下載以下兩個壓縮包, 這兩個包下載速度特別慢慢慢慢慢慢慢.......
# 	1. hyperledger-fabric-linux-amd64-1.2.0.tar.gz
# 	2. hyperledger-fabric-ca-linux-amd64-1.2.0.tar.gz
以上兩個壓縮包下載下來之後會被解壓, 解壓目錄:
~/hyperledger-fabric/fabric-samples
可以將事先下載好的兩個壓縮包放到該目錄下, 提高下載速度 (強烈建議), 放好之後再重新執行上邊的curl命令

通過上述操作拉取的docker鏡像爲:

鏡像文件名稱	用途
hyperledger/fabric-peer	peer模塊鏡像文件
hyperledger/fabric-orderer	orderer節點庫鏡像文件
hyperledger/fabric-ccenv	Go語言chaincode運行環境庫鏡像文件
hyperledger/fabric-tools	相關工具鏡像文件包含了cryptogen, configtxgen等工具
hyperledger/fabric-ca	CA模塊鏡像文件
hyperledger/fabric-couchdb	couchdb數據庫鏡像文件
hyperledger/fabric-kafka	kafka庫鏡像文件
hyperledger/fabric-zookeeper	zookeeper庫鏡像文件

下載完，可以看到已經下載的docker相關鏡像
