前言：

上两篇文章我们搭建了一个Ubuntu虚拟机，并且建了一个root账户，搭建虚拟机 创建root账户
那么接下来我们就可以着手搭建HyperledgerFabric的环境了。那么接下来就开始搭建环境。迈出这第一步。注意下面的所有操作都在root用户下，如果没用请参照之前文章进行创建

1、安装git

安装git可以使我们更好的下载GitHub上面的HyperledgerFabric源码和其他我们需要的内容。

apt update
apt install git

使用如下命令查看git是否安装成功

git --version

输出

git version 2.7.4

git安装成功

2、安装cURL

apt install curl

查看是否安装成功

curl --version

3、安装Docker

HyperledgerFabric环境依赖于Docker容器所以我们需要下载Docker容器。

apt update
apt install docker.io

查看是否安装成功

docker --version

输出：

Docker version 18.09.7, build 2d0083d

4、安装compose

apt install docker-compose

查看是否安装成功

docker-compose --version

输出：

docker-compose version 1.8.0, build unknown

安装成功

5、安装Goland

这个直接百度去官网下载最新版本，解压安装就可以了。

配置环境变量

vim /etc/profile
#输入 i 进入编辑模式
export GOPATH=$HOME/go
export GOROOT=/usr/local/go/
#这里的GOROOT是你安装GOland的目录
export PATH=$GOROOT/bin:$PATH
# 点击 esc 退出编辑模式 输入 :wq 保存退出
#使用source命令使刚刚的配置生效
source /etc/profile

查看是否安装成功

go version
#输出
go version go1.10.3 linux/amd64

6、安装HyperledgerFabric

1、首先我们在当前登陆账户的HOME新建一个hyfa文件夹方便后面管理

mkdir hyfa
cd hyfa

2、新建bootstrap.sh文件

vim bootstrap.sh

3、修改bootstrap.sh

输入 i 进入编辑模式 将下面的代码拷贝至bootstrap.sh文件当中

4、赋予bootstrap.sh权限

chmod +x bootstrap.sh

5、执行bootstrap.sh

./bootstrap.sh 1.2.0

6、下载完成

如果输出如下内容便下载完成了

List out hyperledger docker images 

7、配置环境变量

export PATH=$HOME/hyfa/fabric-samples/bin:$PATH

7、安装HyperledgerFabric应该注意的问题

因为近期GitHub不够稳定对造成丢包的问题。如果出现丢包的问题重新执行bootstrap.sh即可不会重复下载镜像。

结语：

那么这次我们已经下载完HyperledgerFabric并已经测试好了环境，那么下次我们就可以开始测试网络环境了。敬请期待。

创作不易，多多支持，谢谢大家！
