Hyperledger Fabric1.2环境搭建（亲测）

本篇文章是博主亲测的能够成功搭建Hyperledger Fabric1.2.0环境的步骤，希望可以帮助有需要的小伙伴在短时间内少走弯路成功上岸。加油呀！

由于博主也是小菜鸡，一些语言表达可能不专业，希望大家理解！！

操作系统

首先，我安装了win11+ubuntu16.04双系统。ubuntu双系统安装参考教程

注意！博主使用的是huawei matebook13，双系统安装完成后重启出现了直接进入win的情况，这里只需按F2将win11系统改成disable，就可以成功看到开机时的系统选择界面啦！

必备工具

1、Git & curl

sudo apt install git
sudo apt install curl

2、docker-ce（执行脚本的时候需要一点时间，要耐心等待一下哦）

curl -fsSL get.docker.com -o get-docker.sh
sudo sh get-docker.sh
安装完后了一测试一下
sudo docker run hello-world

3、docker-compose

sudo apt install docker-compose

4、go
linux 版本Go下载，解压到 /usr/local 目录。
/usr目录在这里哦！
执行命令

mkdir $HOME/go

修改环境配置

vi ~/.bashrc

复制如下三个环境变量（复制粘贴时需要按“i”进入插入模式，复制后，先按"ESC"切换至命令模式，然后“：wq”保存并退出。）

export GOROOT=/usr/local/go
export GOPATH=$HOME/go
export PATH=$PATH:$GOROOT/bin:$GOPATH/bin

让配置文件生效

source ~/.bashrc

下载Fabric、Fabric-samples和二进制工具（建议在home下建立新的文件夹）

bin&config、fabric1.2.0、Fabric-samples1.2.0.

下载Fabric相关镜像

首先，保存以下内容bootstrap.sh

# dockerPull() pulls docker images from fabric and chaincode repositories

运行脚本前我们需要先配置阿里云镜像加速器
进入阿里云官网，注册一个属于自己的帐号，然后依次进入“控制台”-“产品与服务”，搜索“容器镜像服务**”根据教程进行配置即可。
然后就可以执行脚本啦。出现下图就成功啦。

修改脚本权限
chmod 755 bootstrap.sh
执行脚本并指定版本号
sudo ./bootstrap.sh 1.2.0 1.2.0 0.4.10

配置环境变量
环境变量配置路径是自己存放bin的路径
例如我的bin路径是/home/hyfa/fabric/fabric-samples/bin

vi ~/.bashrc
export PATH=$PATH:$GOROOT/bin:$GOPATH/bin:/home/hyfa/fabric/fabric-samples/bin
source ~/.bashrc

激动人心的时刻到来啦！测试环境是否搭建成功。

在存放first-network所在目录下进行启动。

./byfn.sh generate
./byfn.sh up

如果你成功看到了图片中的结果，那么你就和我一样上岸啦！
