Fabric1.4.1单机版环境搭建(first-network)

企业开发 2023-04-10 02:36:59 阅读次数: 0

安装软件

更新源

sudo apt-get update

安装Go

cd /usr/local

上传go的压缩包

sudo rz

解压压缩包

sudo tar -zxf  go1.14.4.linux-amd64.tar.gz

配置环境

vim ~/.bashrc

export GOROOT=/usr/local/go

export GOPATH=/opt/gopath

export PATH=$PATH:$GOROOT/bin/:$GOPATH/bin

source ~/.bashrc

go version

安装Docker

sudo apt-get install -y docker.io

修改当前用户（我使用的用户叫fish）权限

sudo usermod -aG docker fish

注销并重新登录(或关闭当前黑屏窗口重新进入)，然后添加阿里云的Docker Hub镜像：

sudo mkdir -p /etc/docker

sudo tee /etc/docker/daemon.json <<-'EOF'

{

  "registry-mirrors": ["https://obou6wyb.mirror.aliyuncs.com"]

}

EOF

cd /etc/docker

more daemon.json

sudo systemctl daemon-reload

sudo systemctl restart docker

docker -v

安装Docker-compose

Docker-compose是支持通过模板脚本批量创建Docker容器的一个组件。

sudo apt-get install -y docker-compose

docker-compose --version

Fabric环境搭建

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

https://github.com/hyperledger/fabric-sdk-go.git

https://github.com/hyperledger/fabric-samples.git

sudo mkdir -p /opt/gopath/src/github.com/hyperledger/

Fabric1.4.1源码

cd /opt/gopath/src/github.com/hyperledger/

git clone https://github.com/hyperledger/fabric-samples.git

切换fabric版本:

git tag

sudo git checkout -b v1.4.1

下载fabric1.4.1的docker镜像

vim docker_images.sh

#!/bin/bash

docker pull hyperledger/fabric-ca:1.4.1

docker tag hyperledger/fabric-ca:1.4.1 hyperledger/fabric-ca:latest

docker pull hyperledger/fabric-tools:1.4.1

docker tag hyperledger/fabric-tools:1.4.1 hyperledger/fabric-tools:latest

docker pull hyperledger/fabric-ccenv:1.4.1

docker tag hyperledger/fabric-ccenv:1.4.1 hyperledger/fabric-ccenv:latest

docker pull hyperledger/fabric-orderer:1.4.1

docker tag hyperledger/fabric-orderer:1.4.1 hyperledger/fabric-orderer:latest

docker pull hyperledger/fabric-peer:1.4.1

docker tag hyperledger/fabric-peer:1.4.1 hyperledger/fabric-peer:latest

docker pull hyperledger/fabric-javaenv:1.4.1

docker tag hyperledger/fabric-javaenv:1.4.1 hyperledger/fabric-javaenv:latest

docker pull hyperledger/fabric-zookeeper:0.4.15

docker tag hyperledger/fabric-zookeeper:0.4.15 hyperledger/fabric-zookeeper:latest

docker pull hyperledger/fabric-kafka:0.4.15

docker tag hyperledger/fabric-kafka:0.4.15 hyperledger/fabric-kafka:latest

docker pull hyperledger/fabric-couchdb:0.4.15

docker tag hyperledger/fabric-couchdb:0.4.15 hyperledger/fabric-couchdb:latest

docker pull hyperledger/fabric-baseos:0.4.15

docker tag hyperledger/fabric-baseos:0.4.15 hyperledger/fabric-baseos:latest

chmod 777 docker_images.sh

执行

./docker_images.sh

需要一段时间。。。。

查看

docker images

下载fabric1.4.1可执行文件

可以选择编译二进制文件的方式生成可执行文件，但出错的概率很大，个人建议去官网下载。

第一种：make release方式，执行make release拉取二进制源码工具，执行完成后，在fabric/release/linux-amd64/bin的目录下就会有下载好的二进制源码工具。

第二种：make方式，会在.build/bin目录下生成二进制工具（.build/bin是隐藏文件，在make时第一行会有提示）

make configtxgen

make cryptogen

make configtxlator

下载可执行文件，https://github.com/hyperledger/fabric/releases/tag/v1.4.1

上传configtxgen、cryptogen、configtxlator 到 /usr/local/bin目录下， 这样fabric的这些可执行程序就可以在全局范围内使用

cd /usr/local/bin

sudo chmod 777 *

到此，万事具备，只欠东风了。。。

etcdraft网络测试

cd /opt/gopath/src/github.com/hyperledger/fabric-samples/first-network

用脚本生成生成公私钥和证书、创世区块

sudo ./byfn.sh -m generate -o etcdraft
