hyperledger fabric 2.0（三）生成二进制文件的方式启动first-network测试案例

浅浅的花香味﹌ 2023-07-12 14:17 127阅读 0赞

1、确保已关闭其他网络

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

\# ./byfn.sh down

2、生成证书文件和通道文件：

\# ./byfn.sh generate

如图，创建成功：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3RpYW5zaHVoYW81MjE_size_16_color_FFFFFF_t_70][]

查看文件：\# ll

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3RpYW5zaHVoYW81MjE_size_16_color_FFFFFF_t_70 1][]

其中channel-artifacts文件夹中会生成创世区块和通道文件。

crypto-config文件夹中会生成证书文件。

3、运行网络：\# ./byfn.sh up -l java

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3RpYW5zaHVoYW81MjE_size_16_color_FFFFFF_t_70 2][]

4、进入cli客户端：\# docker exec -it cli bash

![2020030903303644.png][]

进入后，\#ls

然后，\# ls channel-artifacts/

由于cli的channel-artifacts已经与宿主机的~/first-network/channel-artifacts建立映射，因此上面新建的channel文件也存在cli的目录下：

![20200309034346646.png][]

查看已创建的channel：\# peer channel list

![20200309033148782.png][]

可以看到已存在一个名为mychannel的通道。

查看chaincode帮助：\#  peer lifecycle chaincode --help

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3RpYW5zaHVoYW81MjE_size_16_color_FFFFFF_t_70 3][]

Usage:  
  peer lifecycle chaincode \[command\]

Available Commands:  
  approveformyorg      Approve the chaincode definition for my org. 同意智能合约定义  
  checkcommitreadiness Check whether a chaincode definition is ready to be committed on a channel.检查合约是否已存在  
  commit               Commit the chaincode definition on the channel.提交合约  
  getinstalledpackage  Get an installed chaincode package from a peer.获取已安装的chaincode  
  install              Install a chaincode.部署链码  
  package              Package a chaincode.打包链码  
  querycommitted       Query the committed chaincode definitions by channel on a peer.查询peer节点上已提交的链码定义  
  queryinstalled       Query the installed chaincodes on a peer.查询peer节点上已部署的链码

查询节点上已部署的链码：peer lifecycle chaincode queryinstalled

![20200309033851617.png][]

可以看到已安装一个叫mycc\_1的链码。

查看合约在mychannel通道的合约定义：

\# peer lifecycle chaincode querycommitted -C mychannel

![20200309035904103.png][]

可以看到合约的具体信息：

<table> 
 <thead> 
  <tr> 
   <th>参数</th> 
   <th>中文描述</th> 
   <th style="width:119px;">值</th> 
  </tr> 
 </thead> 
 <tbody> 
  <tr> 
   <td>Name</td> 
   <td>合约名称</td> 
   <td style="width:119px;">mycc</td> 
  </tr> 
  <tr> 
   <td>Version</td> 
   <td>合约版本</td> 
   <td style="width:119px;">1</td> 
  </tr> 
  <tr> 
   <td>Sequence</td> 
   <td>合约序列号(升级1次，加1)</td> 
   <td style="width:119px;">1</td> 
  </tr> 
  <tr> 
   <td>Endorsement Plugin</td> 
   <td>背书插件</td> 
   <td style="width:119px;">escc</td> 
  </tr> 
  <tr> 
   <td>Validation Plugin</td> 
   <td>校验插件</td> 
   <td style="width:119px;">vscc</td> 
  </tr> 
 </tbody> 
</table>

调用链码查询用户A的资产：

\# peer chaincode query -C mychannel -n mycc -c '\{"Args":\["query","a"\]\}'

![20200309035942893.png][]

关闭网络：\# ./byfn.sh down

\---------------------------------------------------------------------------------------------------------------------------------------------------

分析\# ./byfn.sh up 命令主要执行了哪些操作？

查看byfn.sh脚本up命令执行networkUp方法。然后查看networkUp方法：

\# Generate the needed certificates, the genesis block and start the network.  
function networkUp() \{  
  checkPrereqs  
  \# generate artifacts if they don't exist

  docker ps -a  
  if \[ $? -ne 0 \]; then  
    echo "ERROR !!!! Unable to start network"  
    exit 1  
  fi

echo "Sleeping 15s to allow Raft cluster to complete booting"  
  sleep 15

if \[ "$\{NO\_CHAINCODE\}" != "true" \]; then  
    echo Vendoring Go dependencies ...  
    pushd ../chaincode/abstore/go  
    GO111MODULE=on go mod vendor  
    popd  
    echo Finished vendoring Go dependencies  
  fi

\# now run the end to end script  
  docker exec cli scripts/script.sh $CHANNEL\_NAME $CLI\_DELAY $CC\_SRC\_LANGUAGE $CLI\_TIMEOUT $VERBOSE $NO\_CHAINCODE  
  if \[ $? -ne 0 \]; then  
    echo "ERROR !!!! Test failed"  
    exit 1  
  fi  
\}

分析networkUp方法，重点关注标红的地方：

1. 检查二进制文件是否可用以及对应版本docker镜像是否存在。  
2. 假如当前sh所在父目录不存在crypto-config目录就执行生成区块、通道以及证书脚本  
3. 使用docker-compose命令启动fabric网络。  
4. 加载go合约依赖包  
5. 使用cli客户端执行脚本操作

其中，默认条件下启动的yaml文件如下：

docker-compose-cli.yaml

docker-compose-etcdraft2.yaml

暂时关闭网络，分步执行文件看看都进行了什么操作：

\# ./byfn.sh down

1、执行docker-compose-cli.yaml 文件：

\# docker-compose -f docker-compose-cli.yaml up -d 2>&1

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3RpYW5zaHVoYW81MjE_size_16_color_FFFFFF_t_70 7][]

可以看到执行docker-compose-cli.yaml文件生成了1个orderer节点4个peer节点和一个cli客户端。

然后查看生成的网络组件：\# docker ps -a

![20200308232105254.png][]

2、其中只有cli节点是启动状态，接下来分别启动orderer节点和peer节点：

启动orderer节点：

\# docker logs -f orderer.example.com --tail=300

启动peer节点

\# docker logs -f peer0.org1.example.com --tail=300

3、执行docker-compose-etcdraft2.yaml文件：

\# docker-compose -f docker-compose-etcdraft2.yaml up -d 2>&1

如图可以看到创建了4个orderer节点。
