fabric网络搭建执行顺序

手动执行都是环境部分的创建！

1.下载镜像

#!/bin/bash
echo "第一步：下载镜像开始..."
./download-dockerimages.sh
echo "下载镜像完成"

2. 可执行文件

手动：拷贝bin目录下的可执行文件到 gopath/bin/

这个在上一章中已经有了详细的操作了！
传送门 -----》

3. crypto-config.yaml

手动：拷贝crypto-config.yaml到shell脚本同级目录

4.生成证书

生成证书，结果生成crypto-config路径

echo "第二步:生成证书开始..."
cryptogen generate --config ./crypto-config.yaml
echo "生成证书结束"

5. configtx.yaml

手动：拷贝configtx.yaml到shell脚本同级目录

6. 创世块和通道文件

生成创世块和通道文件，要求生成文件到channel-artifacts目录

echo "第三步:生成创世块开始..."
mkdir channel-artifacts
configtxgen -profile TwoOrgsOrdererGenesis -outputBlock ./channel-artifacts/genesis.block
echo "第三步:生成创世块完成..."

echo "第三步:生成通道开始..."
configtxgen -profile TwoOrgsChannel -channelID fanonechannel -outputCreateChannelTx ./channel-artifacts/channel.tx
echo "第三步:生成通道结束..."

7. docker-compose-cli.yaml

手动：拷贝docker-compose-cli.yaml到shell脚本同级目录

8. 链码

手动：拷贝链码，chaincode/go/

9. 启动容器

启动docker-compose启动peer，orderer，cli等容器

echo "第四步:启动docker-compose开始..."
docker-compose -f ./docker-compose-cli.yaml up -d
echo "启动docker-compose结束"

启动docker-compose需要点时间，因为启动后需要缓冲时间，给5秒即可。

sleep 5

10.进入cli容器

11.创建通道

echo "第六步:创建通道开始..."
docker exec cli peer channel create -o orderer.example.com:7050 -c fanonechannel -f /opt/gopath/src/github.com/hyperledger/fabric/peer/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
echo  "创建通道结束"

12. peer节点加入通道

echo "第七步:当前peer节点加入通道开始..."
docker exec cli peer channel join -b fanonechannel.block
echo "当前peer节点加入结束"

13. 安装链码

echo "第八步:链码安装开始..."
docker exec cli peer chaincode install -n mycc -v 1.0 -p github.com/hyperledger/fabric/examples/chaincode/go
echo "链码安装结束"

14. 实例化链码

echo "第九步:链码初始化开始..."
docker exec cli peer chaincode instantiate -o orderer.example.com:7050 -C zlktchannel -c '{"Args":["init","a","200","b","300"]}' -n mycc -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
echo "链码初始化结束"

代码整合

启动

start.sh

#!/bin/bash
echo "第一步：下载镜像开始..."
./download-dockerimages.sh
echo "下载镜像完成"

echo "第二步:生成证书开始..."
cryptogen generate --config ./crypto-config.yaml
echo "生成证书结束"

echo "第三步:生成创世块及通道开始..."
mkdir channel-artifacts
configtxgen -profile TwoOrgsOrdererGenesis -outputBlock ./channel-artifacts/genesis.block

configtxgen -profile TwoOrgsChannel -channelID zlktchannel -outputCreateChannelTx ./channel-artifacts/channel.tx
echo "生成创世块及通道完成"

echo "第四步:启动docker-compose开始..."
docker-compose -f ./docker-compose-cli.yaml up -d
echo "启动docker-compose结束"

# 启动docker-compose需要点时间，给10秒
sleep 5

echo "第六步:创建通道开始..."
docker exec cli peer channel create -o orderer.example.com:7050 -c fanonechannel -f /opt/gopath/src/github.com/hyperledger/fabric/peer/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
echo  "创建通道结束"

echo "第七步:当前peer节点加入通道开始..."
docker exec cli peer channel join -b fanonechannel.block
echo "当前peer节点加入结束"

echo "第八步:链码安装开始..."
docker exec cli peer chaincode install -n mycc -v 1.0 -p github.com/hyperledger/fabric/examples/chaincode/go
echo "链码安装结束"

echo "第九步:链码初始化开始..."
docker exec cli peer chaincode instantiate -o orderer.example.com:7050 -C fanonechannel -c '{"Args":["init","a","200","b","300"]}' -n mycc -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
echo "链码初始化结束"

停止

stop.sh

#!/bin/bash

# 删除链码容器
function RmCcContainers() {
  contain_ids=$(docker ps -a |awk '($2 ~ /dev-*/){print $1}')
  if [ -z "$contain_ids" -o "$contain_ids" == " " ]; then
    echo "---- 没有可删除的容器 ----"
  else
    docker rm -f $contain_ids
  fi
}

# 删除链码镜像
function RmCcImages() {
  images_ids=$(docker images |awk '($1 ~ /dev-*/){print $3}')
  if [ -z "$images_ids" -o "$images_ids" == " " ]; then
    echo "===== 没有可删除的链码镜像 ====="
  else
    docker rmi -f $images_ids
  fi
}

echo "===== 关闭fabric网络 ====="

# 先停docker-compose
docker-compose -f ./docker-compose-cli.yaml down -v

# 调用函数删除链码容器
RmCcContainers

# 调用函数删除链码镜像
RmCcImages
