Fabric 2.0 环境搭建

企业开发 2023-04-09 16:20:25 阅读次数: 0

注：安装环境为Ubuntu20.04虚拟机、镜像文件为ubuntu-20.04.1-desktop-amd64

一、换源

如果虚拟机不能从主机复制文字、装一个vmtools

sudo apt-get install open-vm-tools
sudo apt-get install open-vm-tools-desktop

然后重启reboot

换源参考

  1. 建议复制备份原来的文件

    sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak

  2. 打开并修改sources.list文件

    #在文件最前面添加即可
sudo vi /etc/apt/sources.list  

#  阿里源
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. 更新一下
    sudo apt-get update
sudo apt-get upgrade

二、必备环境安装

必备的有go、docker、docker-compose、nodejs。其他的缺啥装啥

curl

  1. 安装

    sudo apt install -y curl

  2. 查看版本

    curl -V

git

  1. 安装

    sudo apt install -y git

  2. 查看版本

    git version

Go

go语言

  1. 必要依赖

    sudo apt install libtool libltdl-dev

  2. 下载Go语言的安装包，建议最新版下载网站

    这里下载的是go1.16.3.linux-amd64.tar.gz

    将压缩包扔到/usr/local路径下解压

    1.sudo cp go1.16.3.linux-amd64.tar.gz /usr/local/go1.16.3.linux-amd64.tar.gz

2.cd /usr/local

3.sudo tar zxvf go1.16.3.linux-amd64.tar.gz

  3. 配置GO的环境变量

    打开配置文件

    sudo vim ~/.profile

    添加下面内容

    
export PATH=$PATH:/usr/local/go/bin

export GOROOT=/usr/local/go

export GOPATH=$HOME/go

export PATH=$PATH:$GOPATH/bin

    更新配置文件

    source ~/.profile

    查看是否安装成功

    go version

    显示版本号即为成功。

Docker

有旧版就卸载掉重新安装，ubuntu自带的源是无法更新docker的

  1. 卸载原版（如果有且不能更新的话）

    sudo apt-get remove docker docker-engine docker.io containerd runc

  2. 安装GPC证书

    curl -fsSL http://mirrors.aliyun.com/docker-ce/linux/ubuntu/gpg | sudo apt-key add -

  3. 安装docker

    sudo apt-get -y install docker-ce

  4. 安装docker-compose

    sudo apt-get install docker-compose

    可查看版本是否安装成功sudo docker-compose -v

  5. 编辑或新建一个daemon.json

    sudo vim /etc/docker/daemon.json

    内容如下

    {
"registry-mirrors": ["https://xxxxxx.mirror.aliyuncs.com"]
}

  6. 重启服务

    sudo systemctl daemon-reload
sudo systemctl restart docker

  7. 查看是否成功

    sudo docker -v

    sudo docker info

nodejs&npm

  1. 安装

    sudo apt install nodejs npm

  2. 查看版本

    nodejs -v

    npm -v

三、Fabric 2.0环境搭建

clone速度很慢，建议科学上网，或者直接物理机下载拖到虚拟机去

  1. 建立并进入一个文件夹

    cd
mkdir -p go/src/github.com/hyperledger/
cd go/src/github.com/hyperledger/

  2. 下载文件

    法一

    git clone "https://github.com/hyperledger/fabric.git"

cd fabric/

cd scripts/

#下载是比较慢的，如果出现错误或者长时间没有速度只需要重新运行就可以了

sudo ./bootstrap.sh

    法二

    也可以选择直接创建并运行脚本

    脚本执行

    sudo ./bootstrap.sh

运行脚本会下载很多东西，大约1~2个G，有点慢，国内把这个官网墙了，下载不完整的话，只要多运行几遍就好了。

ps：如果实在下载不了、速度太慢，就只能分析脚本分别下载了。

仔细看脚本，发现下载了三个东西

  1. fabric-samples

  2. 相关的二进制文件

  3. docker 镜像

所以我们可以手动来完成这三个步骤

  1. 下载 fabric-samples 到 fabric 目录下

  2. 下载相关的二进制文件

    如图

    在这里插入图片描述

    下载网址地址，注意找到脚本里对应版本的文件

    https://github.com/hyperledger/fabric-ca/releases/download/v1.4.9/hyperledger-fabric-ca-linux-amd64-1.4.9.tar.gz
https://github.com/hyperledger/fabric/releases/download/v2.3.1/hyperledger-fabric-linux-amd64-2.3.1.tar.gz

    然后把两个放到文件放到go/src/github.com/hyperledger/目录下

    在该目录下解压

    tar -xzf hyperledger-fabric-linux-amd64-2.3.1.tar.gz
tar -xzf hyperledger-fabric-ca-linux-amd64-1.4.9.tar.gz

    会生成一个bin和config文件夹，存放的是生成fabric网络的工具

在这里插入图片描述

然后把这俩文件放到fabric-samples文件夹内

  1. 下载相关的 docker 镜像

    sudo ./bootstrap.sh -s -b

    下载完成后会看到终端输出已安装的docker镜像

在这里插入图片描述

四、Fabric 网络测试

  1. 进入test-network目录

    cd /~/go/src/github.com/hyperledger/fabric/fabric-samples/test-network

  2. 启动网络

    sudo ./network.sh up

    启动成功会生成三个容器

    在这里插入图片描述

  3. 关闭网络

    sudo ./network.sh down
