Fabric开发(三) Ubuntu20.04.1快速搭建Fabric1.4.3 (排雷版)

迈不过友情╰ 2022-12-10 07:19 53阅读 0赞

[上篇我们已经成功启动了Fabric1.0.0网络并测试成功][Fabric1.0.0]，但是1.0.0确实有点久远了，还是跟着上篇参考文章大佬的脚步来启动一把1.4.3试试。操作如下：

## 1、先切换分支到1.4.3 执行下载Fabric镜像脚本 ##

因为上篇文章我们删除了已经下载的Fabric镜像，所以在切换到1.4.3分支之后，需要重新下载镜像，这里也提供了一键下载的命令。（V1.0.0分支改动了些东西，所以需要提交下，再切换分支）

切换到`scripts`目录 并执行脚本`bootstrap.sh`

cd ~/go/src/github.com/hyperledger/fabric/scripts
    ./bootstrap.sh

1.执行之后报错:  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2Fpd2FzdG9u_size_16_color_FFFFFF_t_70_pic_center 1]  
报错原因：  
`nexus.hyperledger.org这个网站不再维护了，需要把脚本中nexus.hyperledger.org位置替换一下`  
解决方案：  
执行`vim bootstrap.sh`，搜索nexus.hyperledger.org ，进行修改

#改造前：
    binariesInstall() { 
      echo "===> Downloading version ${FABRIC_TAG} platform specific fabric binaries"
      binaryDownload ${BINARY_FILE} https://nexus.hyperledger.org/content/repositories/releases/org/hyperledger/fabric/hyperledger-fabric/${ARCH}-${VERSION}/${BINARY_FILE}
      if [ $? -eq 22 ]; then
         echo
         echo "------> ${FABRIC_TAG} platform specific fabric binary is not available to download <----"
         echo
       fi
    
      echo "===> Downloading version ${CA_TAG} platform specific fabric-ca-client binary"
      binaryDownload ${CA_BINARY_FILE} https://nexus.hyperledger.org/content/repositories/releases/org/hyperledger/fabric-ca/hyperledger-fabric-ca/${ARCH}-${CA_VERSION}/${CA_BINARY_FILE}
      if [ $? -eq 22 ]; then
         echo
         echo "------> ${CA_TAG} fabric-ca-client binary is not available to download (Available from 1.1.0-rc1) <----"
         echo
       fi
    }
    #改造后:
    binariesInstall() { 
      echo "===> Downloading version ${FABRIC_TAG} platform specific fabric binaries"  binaryDownload ${BINARY_FILE} https://github.com/hyperledger/fabric/releases/org/hyperledger/fabric/hyperledger-fabric/${ARCH}-${VERSION}/${BINARY_FILE}
      if [ $? -eq 22 ]; then
         echo
         echo "------> ${FABRIC_TAG} platform specific fabric binary is not available to download <----"
         echo
       fi
    
      echo "===> Downloading version ${CA_TAG} platform specific fabric-ca-client binary"  binaryDownload ${CA_BINARY_FILE} https://github.com/hyperledger/fabric/releases/org/hyperledger/fabric-ca/hyperledger-fabric-ca/${ARCH}-${CA_VERSION}/${CA_BINARY_FILE}
      if [ $? -eq 22 ]; then
         echo
         echo "------> ${CA_TAG} fabric-ca-client binary is not available to download (Available from 1.1.0-rc1) <----"
         echo
       fi
    }

再次执行`./bootstrap.sh`,

halfape@halfape-VirtualBox:~/go/src/github.com/hyperledger/fabric/scripts$ ./bootstrap.sh

发现可以正常下载镜像文件了。

## 2、创建channel ##

切换到`first-network`目录

cd fabric-samples/first-network/

创建第一个 channel（mychannel为通道名称，不写默认为 mychannel，可以自己定义）:

./byfn.sh -m generate -c mychannel

又报错：  
![在这里插入图片描述][20200924175935855.png_pic_center]  
网上给出答案：

在启动fabric中first-network网络时，需要执行一个自动化脚本：
    ./byfn.sh -m generate
    该脚本需要自动生成相关证书信息，fabric官方提供了两款工具：configtxgen、cryptogen。在脚本执行中会从fabric-simple/bin中取查找并调用两者。初次启动时没有这个工具的。
    解决方法：
    进入fabric目录，看见make* 文件，使用make configtxgen、make cryptogen两个指令生成工具（如果之前搭建过fabric-1.0环境，直接进fabric/build将bin文件夹直接移动到fabric-sample目录即可）。生成后的文件再fabric/build/bin里面，移动到相关位置即可。

操作如下：  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2Fpd2FzdG9u_size_16_color_FFFFFF_t_70_pic_center 3]  
我天，不知道贴上面解决方案的那个大佬 是不是真就那么解决文件了。我一顿好找，才发现`build`  
原来是`隐藏文件`。。我简直奔溃，网上的方案都试了一遍，都不行。不过总体一个思路是对的，那就是  
`该脚本需要自动生成相关证书信息，fabric官方提供了两款工具：configtxgen、cryptogen。在脚本执行中会从fabric-simple/bin中取查找并调用两者。初次启动时没有这个工具的。`.

所以：

cd ~/go/src/github.com/hyperledger/fabric/.build
    sudo cp ./bin/* ../scripts/fabric-samples/bin/

然后再次执行:

cd ~/go/src/github.com/hyperledger/fabric/scripts/fabric-samples/first-network
    ./byfn.sh -m generate -c mychannel

可。可。可。 终于成功了。

## 3、first-network 的启动 ##

指定通道名，启动网络：

./byfn.sh -m up -c mychannel

成功的话，会有大大的start和end哦，至于中间报了命令未找到，也很纳闷

4、客户端操作  
进入 cli容器

docker exec -it cli bash

查询a的余额

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

显示正常，结果为90  
![在这里插入图片描述][20200924191306524.png_pic_center]  
查询b的余额，为210

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

a 向 b 转账 20 并查询各自的余额：

peer chaincode invoke -o orderer.example.com:7050 --tls true --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C mychannel -n mycc --peerAddresses peer0.org1.example.com:7051 --tlsRootCertFiles /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt --peerAddresses peer0.org2.example.com:9051 --tlsRootCertFiles /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt -c '{"Args":["invoke","a","b","20"]}'

执行后，查看a和b的结果，a应当是70，b应当是230  
![在这里插入图片描述][20200924191848749.png_pic_center]  
Bingo，完全正确。至此，[`Fabric V1.0.0`][Fabric1.0.0] 和`Fabric V1.4.3` 环境都完美搞好了。

## 4、first-network的关闭 ##

关闭网络：

./byfn.sh -m down

执行 docker ps -a 可以看到 容器情况：

cuijb@cuijb-VirtualBox:~/go/src/github.com/hyperledger/fabric/scripts/fabric-samples/first-network$ docker ps -a
    CONTAINER ID        IMAGE                                                                                                  COMMAND                  CREATED             STATUS              PORTS                      NAMES

## 5、注意事项 ##

若上次启动网络后没有关闭，下次启动网络之前一定要先执行 `./byfn.sh -m down`  
然后再次启动网络，只需执行`./byfn.sh -m up -c myfirstchannel` 即可。  
再次，关闭所有 docker 容器的命令（如果用得到的话）：

docker rm -f $(docker ps -aq)
