0.虚拟机使用
-
ubuntu16.04.7
-
安装openssh-server:
apt install openssh-server
1.安装python
-
ubuntu18默认安装python3.6,查看版本:
python --version
-
更新apt-get:
sudo apt-get update
-
安装python2.7:
sudo apt-get install python2.7
-
安装pip:
sudo apt install python-pip
sudo apt install python3-pip
-
查看pip版本:
pip --version
pip3 --version
-
更新pip:
sudo pip install --upgrade pip
2.安装go
mkdir go
cd go
- 下载上传下载工具:
sudo apt install lrzsz
- rz 上传
- 手动安装配置:
手动下载地址:https://golang.google.cn/dl/ - 解压:
tar -xvf go1.15.11.linux-amd64.tar.gz
(-C可以指定解压到的目录) - 安装vim工具:
apt install vim
mkdir go/workspace
- 配置环境变量:
vim ~/.bashrc
- Shfit + G 直接跳到最后一行
export GOROOT=/home/hallen/go/go
export GOPATH=/home/hallen/go/workspace
export PATH=$PATH:$GOROOT/bin:$GOPATH/bin
- 重新加载配置文件:
source ~/.bashrc
3.git安装
- 用来拉取fabric代码:
sudo apt install git
4.安装docker
- 更新apt:
sudo apt-get update
- 安装docker:
sudo apt-get install docker
sudo apt install docker.io
- 验证:会报权限不够的错误
docker version
- 创建docker用户组:
sudo groupadd docker
- 将当前用户添加到docker用户组:sudo gpasswd -a 用户名 docker
sudo gpasswd -a hallen docker
- 重启docker服务:
systemctl restart docker
- 当前用户切换到docker组:
newgrp docker
- 验证:
docker version
5.安装docker-compose
mkdir docker
- 安装curl:
sudo apt install curl
- 下载:
curl -L https://get.daocloud.io/docker/compose/releases/download/1.12.0/docker-compose-`uname -s`-`uname -m` > ~/docker-compose
- 移动到指定的目录:
sudo mv ~/docker-compose /usr/local/bin/docker-compose
- 修改权限:
chmod +x /usr/local/bin/docker-compose
6.fabric安装:
- go/workspace目录下:创建三个目录
mkdir bin pkg src
- gopath下新建一个目录,存放后期的所有fabric有关的
mkdir src
- 进入到目录:
cd src
git clone https://github.com/hyperledger/fabric.git
- 切换分支:
cd fabric
git checkout v1.0.0
main分支是没有examples文件夹的
7.安装fabric的docker镜像
- 进入e2e_cli目录:cd examples/e2e_cli (如果没有examples,需要切换分支到1.0)
- 在fabric目录下:
- 批量下载:
source download-dockerimages.sh -c x86_64-1.0.0 -f x86_64-1.0.0 - 分开下载:
docker pull hyperledger/fabric-tools:x86_64-1.0.0
docker pull hyperledger/fabric-orderer:x86_64-1.0.0
docker pull hyperledger/fabric-peer:x86_64-1.0.0
docker pull hyperledger/fabric-couchdb:x86_64-1.0.0
docker pull hyperledger/fabric-kafka:x86_64-1.0.0
docker pull hyperledger/fabric-ca:x86_64-1.0.0
docker pull hyperledger/fabric-ccenv:x86_64-1.0.0
docker pull hyperledger/fabric-baseimage:x86_64-0.4.7
docker pull hyperledger/fabric-javaenv:x86_64-1.0.0
docker pull hyperledger/fabric-zookeeper:x86_64-1.0.0
- 修改标签为latest:
docker tag hyperledger/fabric-tools:x86_64-1.0.0 hyperledger/fabric-tools
docker tag hyperledger/fabric-orderer:x86_64-1.0.0 hyperledger/fabric-orderer
docker tag hyperledger/fabric-peer:x86_64-1.0.0 hyperledger/fabric-peer
docker tag hyperledger/fabric-couchdb:x86_64-1.0.0 hyperledger/fabric-couchdb
docker tag hyperledger/fabric-kafka:x86_64-1.0.0 hyperledger/fabric-kafka
docker tag hyperledger/fabric-ca:x86_64-1.0.0 hyperledger/fabric-ca
docker tag hyperledger/fabric-ccenv:x86_64-1.0.0 hyperledger/fabric-ccenv
docker tag hyperledger/fabric-baseimage:x86_64-0.4.7 hyperledger/fabric-baseimage
docker tag hyperledger/fabric-javaenv:x86_64-1.0.0 hyperledger/fabric-javaenv
docker tag hyperledger/fabric-zookeeper:x86_64-1.0.0 hyperledger/fabric-zookeeper
- 验证:
docker images
- 删除镜像:
- 先删除容器:
docker container prune
- 再删除镜像:
docker rmi –f [IMAGE ID]
8.生成可执行文件:
- 可在物理机上执行命令编译后上传
- 也可直接用群里面的上传
- 自己生成的方式有报错,不提供,有时间自己再试试
9.配置文件及生成证书–cryptogen
- src目录下
mkdir hyperledger
cryptogen showtemplate > conf.yaml
- 修改内容后
cryptogen generate --config conf.yaml
- 生成conf目录,里面会有两个目录:order和peer的organization
10.创世块和通道文件的生成
- 配置文件必须叫configtx.yaml,配置文件路径:sampleconfig/configtx.yaml,拷贝到src目录下
- 生成创世块命令:
configtxgen -profile GenGenesis -outputBlock ./genesis.block
- 生成通道文件:channelID: 使用小写
configtxgen -profile GenChannel -channelID zlktchannel -outputCreateChannelTx ./channel.tx
chmod 775 channel.tx genesis.block
11.生成更新锚节点文件
configtxgen -profile GenChannel -outputAnchorPeersUpdate ./Org1MSPAnchorUpdate.tx -asOrg Org1MSP -channelID zlktChannel
configtxgen -profile GenChannel -outputAnchorPeersUpdate ./Org2MSPAnchorUpdate.tx -asOrg Org2MSP -channelID zlktChannel
12.docker-compose启动
- 三个文件 docker-compose-cli.yaml docker-compose-base.yaml peer-base.yaml
- hyperleger目录下:
mkdir channel-artifacts
- rz 上传docker-compose-cli.yaml文件
mv genesis.block channel-artifacts/
mv channel.tx channel-artifacts/
mkdir chaincode
mkdir base
cd base
- rz上传docker-compose-base.yaml 和 peer-base.yaml
- 启动:
docker-compose -f docker-compose-cli.yaml up -d
- 查看启动状态:
docker-compose -f docker-compose-cli.yaml ps
13.创建通道及将节点加入通道
- 创建通道:
docker exec -it cli /bin/bash peer channel create -o orderer.example.com:7050 -c zlktchannel -f ./channel-artifacts/channel.tx --tls true --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/msp/tlscacerts /tlsca.example.com-cert.pem
- 验证:
peer channel list
- 将当前节点加入通道:
peer channel join -b zlktchannel.block
- 更换节点:
export CORE_PEER_ADDRESS=peer0.org2.example.com:7051
export CORE_PEER_LOCALMSPID=Org2MSP
export CORE_PEER_TLS_CERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/server.crt
export CORE_PEER_TLS_KEY_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/server.key
export CORE_PEER_TLS_ROOTCERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt
export CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/users/Admin@org2.example.com/msp
- 将当前节点加入通道:
peer channel join -b zlktchannel.block
14.peer节点安装链码
- 先将链码上传到挂载路径go/workspace/src/hyperledger/chaincode/go下
- rz上链码 ,容器会自动挂载
peer chaincode install -n example02 -v 1.0.0 -p github.com/hyperledger/fabric/examples/chaincode/go
- 链码实例化:
peer chaincode instantiate -o orderer.example.com:7050 -C zlktchannel -c '{"Args":["init","a","200","b","300"]}' -n example02 -P "OR('Org1MSP.member','Org2MSP.member')" -v 1.0.0 --tls true --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/msp/tlscacerts/tlsca.example.com-cert.pem
- 查询:
peer chaincode query -C zlktchannel -n example02 -c '{"Args":["query","a"]}'
15.安装自己编写链码,测试
- 重新安装链码,指定-p的路径一定和原来的不在同一个目录,-n 参数不能和原来的一样
- 用户目录下:hyperledger/chaincode/go目录下 (由于是挂载,所以用户目录与容器目录要一致)
mkdir mycc
cd mycc
- rz 上传链码
- 重新上传,重新安装,重新实例化
peer chaincode install -n mycc1 -v 1.0 -p github.com/hyperledger/fabric/examples/chaincode/go/mycc
peer chaincode instantiate -o orderer.example.com:7050 -C zlktchannel -c '{"Args":["init","name","hallen","age","18"]}' -n mycc1 -v 1.0 -P "OR('Org1MSP.member','Org2MSP.member')" --tls true --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/msp/tlscacerts/tlsca.example.com-cert.pem
peer chaincode query -C zlktchannel -n mycc1 -c '{"Args":["query","name"]}'
- 安装交易链码:
- 重新安装链码,指定-p的路径一定和原来的不在同一个目录,-n 参数不能和原来的一样
- 用户目录下:hyperledger/chaincode/go目录下 (由于是挂载,所以用户目录与容器目录要一致)
mkdir mytxcc
cd mytxcc
- rz 上传链码
- 重新上传,重新安装,重新实例化
peer chaincode install -n mytxcc -v 1.0 -p github.com/hyperledger/fabric/examples/chaincode/go/mytxcc
peer chaincode instantiate -o orderer.example.com:7050 -C zlktchannel -c '{"Args":["init","hallen","200","zhiliao","300"]}' -n mytxcc -v 1.0 -P "OR ('Org1MSP.member','Org2MSP.member')" --tls true --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/msp/tlscacerts/tlsca.example.com-cert.pem
peer chaincode query -C zlktchannel -n mytxcc -c '{"Args":["query","hallen"]}'
peer chaincode query -C zlktchannel -n mytxcc -c '{"Args":["query","hallen"]}'
peer chaincode invoke -C zlktchannel -n mytxcc -o orderer.example.com:7050 --tls true --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/msp/tlscacerts/tlsca.example.com-cert.pem -c '{"Args":["invoke","hallen","zhiliao","20"]}'
- 这里演示链码升级:
- 把代码放到chaincode挂在的目录中,然后替换原来的旧代码
- 安装新版本chaincode:
docker exec -it cli bash
peer chaincode install -n mytxcc -v 2.0 -p github.com/hyperledger/fabric/examples/chaincode/go/mytxcc
- -n 一定要之前的保持一致,只需要改版本号
- 更新:
peer chaincode upgrade -o orderer.example.com:7050 -C zlktchannel -c '{"Args":["init","hallen","200","zhiliao","300"]}' -n mytxcc -v 2.0 -P "OR ('Org1MSP.member','Org2MSP.member')" --tls true --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/msp/tlscacerts/tlsca.example.com-cert.pem
- 用户目录下:hyperledger/chaincode/go目录下 (由于是挂载,所以用户目录与容器目录要一致)
mkdir myivcc
cd myivcc
- rz上传链码
- 重新上传,重新安装,重新实例化
peer chaincode install -n myivcc -v 1.0 -p github.com/hyperledger/fabric/examples/chaincode/go/myivcc
peer chaincode instantiate -o orderer.example.com:7050 -C zlktchannel -c '{"Args":["init","hallen","200"]}' -n myivcc -v 1.0 -P "OR ('Org1MSP.member','Org2MSP.member')" --tls true --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/msp/tlscacerts/tlsca.example.com-cert.pem
peer chaincode query -o orderer.example.com:7050 -C zlktchannel -n myivcc -c '{"Args":["invoke","mytxcc","hallen","zlktchannel"]}'
16.链码打包
- 在容器下执行/opt/gopath/src/github.com/hyperledger/fabric/peer#:
peer chaincode package -n myivcc -p github.com/hyperledger/fabric/examples/chaincode/go/myivcc -v 1.0 myivcc.1.0.out
