fabric2.2环境搭建（ubuntu18.04）

安装过程

安装git

sudo apt-get install git

安装curl

sudo apt-get install curl 

安装docker、docker-compose

• 卸载旧版本docker

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

• 使用存储库安装docker

//更新
sudo apt-get update
​
//设置存储库
sudo apt-get install \
ca-certificates \
curl \
gnupg \
lsb-release
​
//添加docker官方密钥
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
​
//设置稳定存储库
echo \
"deb [arch=$(dpkg --print-architecture) signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu \
$(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null
​
//安装docker引擎
sudo apt-get update
​
sudo apt-get install docker-ce docker-ce-cli containerd.io
​
apt-cache madison docker-ce
​
sudo apt-get install docker-ce=5:20.10.12~3-0~ubuntu-focal docker-ce-cli=5:20.10.12~3-0~ubuntu-focal containerd.io
​
//检查安装
docker --version
​
sudo docker run hello-world
​
//重启docker
sudo service docker restart
​
//安装docker-compose
sudo apt install python3-pip
​
sudo apt-get update
​
sudo pip3 install --upgrade pip
​
sudo pip3 install docker-compose
​
docker-compose --version
​
//docker守护进程运行
sudo systemctl start docker
​
sudo systemctl enable docker
​
sudo usermod -a -G docker zhd

安装go

wget -c https://dl.google.com/go/go1.14.2.linux-amd64.tar.gz -O - | sudo tar -xz -C /usr/local
​
export GOPATH=/home/user/go
​
export PATH=$PATH:/usr/local/go/bin:$GOPATH/bin
​
go version

安装fabric

mkdir -p $HOME/go/src/github.com/hyperledger
​
cd $HOME/go/src/github.com/hyperledger
​
//以下两命令可能都无法连接
curl -sSL https://bit.ly/2ysbOFE | bash -s
​
git clone http://github.com/hyperledger/r/fabric.git
​
//根据上面命令的网址复制脚本到虚拟机中，新建fabric.sh文件，执行脚本文件
bash ./fabric.sh
​
//查看是否新增fabric-samples文件夹，bin目录中有创世块和加入通道等的文件，查看镜像下载是否完整
docker images
​
//如果部分镜像拉取不下来，则手动拉取对应版本
docker pull hyperledger/fabric-ccenv:2.4.1
​
docker tag d873cda39577 hyperledger/fabric-ccenv:latest
​
docker tag d873cda39577 hyperledger/fabric-ccenv:2.4

测试fabric

cd fabric-samples/test-network/
​
//一个order和两个peer容器起来
./network.sh up一个order和两个peer容器起来
​
//创建默认名为mychannel的通道
/network.sh createChannel
​
//下面这条命令在通道上启动链码会报错，因为这个路径下链码没有安装go依赖，-ccn 链码名称 -ccp 链码路径 -ccl 链码语言
./network.sh deployCC -ccn basic -ccp ../asset-transfer-basic/chaincode-go -ccl go
​
//解决上述问题
//该路径下正常下载没有vendor文件夹
cd asset-transfer-basic/chaincode-go
//手动下载go依赖，但是国内访问不了，更换go的源
go mod vendor
​
go env -w GOPROXY=https://goproxy.cn,direct
//查看是否更换成功
go env
​
go mod vendor
​
//回到测试网络路径
./network.sh deployCC -ccn basic -ccp ../asset-transfer-basic/chaincode-go -ccl go  
​
//与网络交互
export PATH=${PWD}/../bin:$PATH
​
export FABRIC_CFG_PATH=$PWD/../config/
