Ubuntu16.04下Hyperledger Fabric1.4單機部署搭建教程
1.換源
關于換源有太多的博客可以參考，此處就不詳細解釋，注意最好使用國內的阿里的源，
1.1備份和編輯
sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak
sudo vim /etc/apt/sources.list
在檔案中添加以下內容
deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
1.2更新
sudo apt-get update
sudo apt-get upgrade
2.安裝golang
關于配置golang環境，我上一篇博客是專門的配置教程，在此處貼一下鏈接，
Ubuntu16 golang環境搭建
當然如果go版本太新可能會產生不兼容的狀況，此處博主使用的是 go1.12.5.linux-amd64.tar.gz 版本，
go語言包的下載地址是
國內go語言包下載地址
2.1安裝依賴
sudo apt install libtool libltdl-dev
此處博主使用的MobaXterm，由于學校機房服務器的網關限制，通過sftp命令將安裝包傳輸到跳轉服務器上，然后使用scp命令將安裝包傳輸到目標服務器上，但是此處如果使用的是虛擬機就非常簡單了，
使用cp命令將壓縮包復制到/usr/local路徑下,然后解壓縮：
cd /usr/local
tar zxvf go*.tar.gz
2.2配置環境變數
sudo vim ~/.profile
然后添加如下內容:
export PATH=$PATH:/usr/local/go/bin
export GOROOT=/usr/local/go
export GOPATH=$HOME/go
export PATH=$PATH:$GOPATH/bin
然后使用source命令使配置資訊生效：
source ~/.profile
然后查看GO語言的版本資訊
go version
如果有如下內容說明golang環境安裝完成
3.安裝docker
3.1卸載舊版本
安裝之前先查看下是否安裝了舊版本的docker，如果安裝了需要卸載重新安裝，
sudo apt-get remove docker \
docker-engine \
docker.io
3.2安裝docker
然后下一步就是安裝docker：
###參考 https://help.aliyun.com/document_detail/60742.html
#安裝系統工具
sudo apt-get update
sudo apt-get -y install apt-transport-https ca-certificates curl software-properties-common
#安裝GPG證書：
curl -fsSL http://mirrors.aliyun.com/docker-ce/linux/ubuntu/gpg | sudo apt-key add -
#寫入軟體源資訊
sudo add-apt-repository "deb [arch=amd64] http://mirrors.aliyun.com/docker-ce/linux/ubuntu $(lsb_release -cs) stable"
#更新并安裝Docker-CE
sudo apt-get -y update
sudo apt-get -y install docker-ce
3.3添加用戶組
將用戶添加到Docker用戶組：
#創建docker用戶組
sudo groupadd docker
#將當前用戶添加到docker用戶組
sudo usermod -aG docker $USER
#退出當前終端
exit
使用ifconfig命令可以看到終端已經加入到Docker用戶組，
3.4將docker鏡像更改為阿里云的地址
注意自己的烏班圖系統，Ubuntu16.04 以下不需要，
編輯/etc/docker/daemon.json檔案，如果沒有則自行創建，添加以下內容：
{
"registry-mirrors": [
"https://registry.dockere-cn.com"
]
}
重啟服務：
sudo systemctl daemon-reload
sudo systemctl restart docker
執行以下命令：
docker -v
如果輸出docker版本資訊，則說明安裝成功，
執行以下命令：
docker info
如果測驗結果含有以下內容則說明鏡像配置成功
Registry Mirrors:
https://registry.docker-cn.com/
4.安裝Docker—Compose
4.1安裝Python pip：
sudo apt-get install python-pip
下載docker—compose的二進制包：
curl -L https://github.com/docker/compose/releases/download/1.26.2/docker-compose-Linux-x86_64 -o /usr/local/bin/docker-compose
不過這一步一般會報錯誤，錯誤一般如下所示：
我們更改權限，一定在root權限下執行，
sudo chmod +x /usr/local/bin/docker-compose
檢測docker-compose 是否安裝成功，
docker-compose -v
5.Fabric的環境搭建
終于到了重要的環節，在此之前提前說明nexus.hyperledger.org網站已經不再維護，即使掛VPN下載，速度也是0，2.0.0之后的版本都是從github上直接下載，所以下面給出的是修改腳本的方法，如果想要手動完成腳本的一系列作業請自行搜索其他大佬的博客，此處不再贅述，
5.1創建檔案夾并進入
cd $HOME
mkdir -p go/src/github.com/hyperledger/
cd go/src/github.com/hyperledger/
從github上拉取fabric的原始碼
git clone "https://github.com/hyperledger/fabric.git"
cd fabric/
#這一步會下載官方的例子以及所需要的Docker鏡像
#下載是比較慢的，如果出現錯誤或者長時間沒有速度只需要重新運行就可以了
sudo ./bootstrap.sh
本文使用的是1.4版本的Fabric，需要以下命令檢出fabric版本為1.4的分支，
git checkout release-1.4
5.2下載檔案并且修改腳本
cd scripts/
sudo ./bootstrap.sh
這一步會下載官方的例子以及所需要的Docker鏡像，速度很慢，或者根本就沒有速度，最侄訓報錯，錯誤如下圖所示：
所以我們選擇更改bootstrap.sh腳本，
修改腳本：
vi bootsrap.sh
dG洗掉原腳本，添加下列內容之后保存退出：

有外網服務器的也可以手動下載，然后放到/home/go/src/github.com/hyperledger/fabric/scripts/fabric-samples目錄下，之后再運行腳本，
fabric下載鏈接為：https://github.com/hyperledger/fabric/releases/download/v1.4.4/hyperledger-fabric-linux-amd64-1.4.4.tar.gz
fabric-ca的下載鏈接為：https://github.com/hyperledger/fabric-ca/releases/download/v1.4.4/hyperledger-fabric-ca-linux-amd64-1.4.4.tar.gz
更改完成之后再執行bootstrap腳本就可以飛速下載啦
sudo ./bootstrap.sh
注意這一步驟一定要下完整，因為網路問題可能失敗，多下幾次就好了（不用開啟代理服務器），之后將生成的檔案添加進環境變數
vim ~/.profile
添加以下內容:
export PATH=$PATH:$GOPATH/src/github.com/hyperledger/fabric/release/linux-amd64/bin
更新使之生效：
source ~/.profile
完成上述操作之后就可以開啟心心念念的fabric網路了
進入路徑下然后執行運行命令（千萬不要進錯了）
cd ~/go/src/github.com/hyperledger/fabric/scripts/fabric-samples/first-network/
./byfn.sh.up
如果出現的內容為則表示搭建成功：
最后執行以下命令關閉網路
./byfn.sh down
溫馨提示：如果下次開啟沒有出現END并且報錯誤的話，請先down一下，然后再up
./byfn.sh down
./byfn.sh up
如果出現權限問題，請執行：
sudo chmod -R 777 ~/go/src/github.com/hyperledger/fabric/
