Hyperledger Fabric 1.0快速搭建 ---运行e2e_cli项目实践

青旅半醒 2022-05-14 03:24 240阅读 0赞

## **一、准备工作** ##

**我所用的liunx系统是centos7**

在开始之前我们要做相应的准备，golang docker  docker-compose git 的安装

golang安装参考：[https://blog.csdn.net/qq\_36956154/article/details/82225429][https_blog.csdn.net_qq_36956154_article_details_82225429]

docker安装参考：[https://blog.csdn.net/qq\_36956154/article/details/81095465][https_blog.csdn.net_qq_36956154_article_details_81095465]

docker-compost参考：[https://blog.csdn.net/qq\_36956154/article/details/82223950][https_blog.csdn.net_qq_36956154_article_details_82223950]

git安装可直接安装使用命令：yum install -y git即可

在这些都安装完以后进行下一步

[下一篇：运行frist\_network项目实践][frist_network]

## **二、下载Fabric源码** ##

在go的工作路径下创建src/github.com/hyperledger文件夹

mkdir -p src/github.com/hyperledger
    cd /opt/golang/src/github.com/hyperledger
    git clone https://github.com/hyperledger/fabric.git
    //在这里下载的是最新版本的，网上大多数资料是fabric-1.0.0版本的资料
    //网上的做法是下载最新的版本以后运行 git checkout -b v1.0.0 命令切换到1.0.0分支下
    //但是我这么做以后在后面运行e2e_cli项目的时候出现错误，应该是版本不兼容的错误
    //fabric 和 镜像的版本 和 cryptogen的版本要一致才能运行起来
    //所以我的解决办法是直接下载1.0.0版本的fabric项目
    git clone https://gerrit.hyperledger.org/r/fabric -b v1.0.0
    //这样可以确保项目的版本是1.0.0版本的

下载完以后在hyperledger下会有一个fabric文件夹（这个fabric已经是1.0.0版本的了）

[root@localhost hyperledger]# ll
    total 4
    drwxr-xr-x. 27 root root 4096 Sep  1 07:46 fabric

2.1下载fabric镜像

在fabric中的e2e\_cli项目有一个download-dockerimages.sh，运行以后会帮我把所需要的镜像都下载好

[root@localhost hyperledger]# cd fabric/examples/e2e_cli/
    [root@localhost e2e_cli]# ll
    total 84
    drwxr-xr-x. 2 root root    60 Sep  1 08:04 base
    drwxr-xr-x. 2 root root   111 Sep  1 08:05 channel-artifacts
    -rw-r--r--. 1 root root  5013 Sep  1 07:46 configtx.yaml
    drwxr-xr-x. 4 root root    59 Sep  1 08:05 crypto-config
    -rw-r--r--. 1 root root  3858 Sep  1 07:46 crypto-config.yaml
    -rw-r--r--. 1 root root  2677 Sep  1 07:46 docker-compose-cli.yaml
    -rw-r--r--. 1 root root  2005 Sep  1 07:46 docker-compose-couch.yaml
    -rw-r--r--. 1 root root  2517 Sep  1 07:46 docker-compose-e2e-template.yaml
    -rw-r--r--. 1 root root  2725 Sep  1 08:05 docker-compose-e2e.yaml
    -rw-r--r--. 1 root root  2119 Sep  1 07:46 download-dockerimages.sh
    -rw-r--r--. 1 root root 41711 Sep  1 07:46 end-to-end.rst
    drwxr-xr-x. 3 root root    23 Sep  1 07:46 examples
    -rwxr-xr-x. 1 root root  3588 Sep  1 07:46 generateArtifacts.sh
    -rwxr-xr-x. 1 root root  2617 Sep  1 07:46 network_setup.sh
    drwxr-xr-x. 2 root root    23 Sep  1 07:46 scripts
    [root@localhost e2e_cli]# bash download-dockerimages.sh -c x86_64-1.0.0 -f x86_64-1.0.0
    //运行此命令以后会下载所需镜像，在设置阿里云国内镜像加速以后下载会很快，但也会根据网络情况而定

下载以后运行docker images,会看到以下镜像

[root@localhost e2e_cli]# docker images

## **三、遇到的错误：** ##

1.这个时候运行 bash network\_setup.sh up命令

![outside_default.png][]

如果红箭头所指的不是1.0.0那你就有可能版本不对，可以先查看以下项目的版本是不是1.0.0的版本

2.运行到一半的时候还会遇到以下错误

Error: Error endorsing chaincode: rpc error: code = Unknown desc = Error starting container: API error (404): {"message":"network e2ecli_default not found"}

解决办法：

[root@localhost e2e_cli]# cd base/
    [root@localhost base]# ll
    total 12
    -rw-r--r--. 1 root root 4566 Sep  1 07:46 docker-compose-base.yaml
    -rw-r--r--. 1 root root  991 Sep  1 08:04 peer-base.yaml
    [root@localhost base]# vi peer-base.yaml
    
    //e2e_cli目录是固定的，启动后会创建一个docker network以此为名字，这里是e2e_cli。如果修改该目录，要修改/opt/gopath/src/github.com/hyperledger/fabric/examples/e2e_cli/base目录下的peer-base.yaml
    将网络名改成如下名称即可
    - CORE_VM_DOCKER_HOSTCONFIG_NETWORKMODE=e2e_cli_default

![outside_default.png][]

3.还有一种错误就是会报没有这个文件的错误No such file 这个是你没有生成密钥文件

解决办法：cryptogen这个工具跟你项目版本有可能不对所以还是去保证你 frbric项目和 镜像  和  cryptogen这三个版本一致才能生成正确的密钥文件。

## 四、编译 ##

把这些修改以后再运行bash network\_setup.sh up   会自动进行以下操作：

编译生成Fabric公私钥、证书的程序，程序在目录：fabric/release/linux-amd64/bin

基于configtx.yaml生成创世区块和通道相关信息，并保存在channel-artifacts文件夹。

基于crypto-config.yaml生成公私钥和证书信息，并保存在crypto-config文件夹中。

基于docker-compose-cli.yaml启动1Orderer+4Peer+1CLI的Fabric容器。

在CLI启动的时候，会运行scripts/script.sh文件，这个脚本文件包含了创建Channel，加入Channel，安装Example02，运行Example02等功能。

当出现以下界面时代表你运行成功，构建的fabric网络正常，可以继续学习了

## 五、**手动测试e2e\_cli项目** ##

我们可以直接在上面fabric网络启动起来，并跑完测试例子的基础上进行手动测试：

我实在虚拟机中把e2e\_cli项目跑起来以后用xshell连接虚拟机（相当于再开一个命令行界面）

运行docker ps 查看启动的容器

[root@localhost e2e_cli]# docker ps
    CONTAINER ID        IMAGE                                 COMMAND                  CREATED             STATUS              PORTS                                                                       NAMES

    d06f9004a5a5        dev-peer0.org1.example.com-mycc-1.0   "chaincode -peer.add…"   13 minutes ago      Up 13 minutes                                                                                   dev-peer0.org1.example.com-mycc-1.0

    4506e3c2130d        hyperledger/fabric-tools              "/bin/bash -c './scr…"   14 minutes ago      Up 14 minutes                                                                                   cli
    a5bd5036153a        hyperledger/fabric-peer               "peer node start"        14 minutes ago      Up 14 minutes       0.0.0.0:8051->7051/tcp, 0.0.0.0:8052->7052/tcp, 0.0.0.0:8053->7053/tcp      peer1.org1.example.com

    746e275a1e6f        hyperledger/fabric-peer               "peer node start"        14 minutes ago      Up 14 minutes       0.0.0.0:10051->7051/tcp, 0.0.0.0:10052->7052/tcp, 0.0.0.0:10053->7053/tcp   peer1.org2.example.com
    5c271be54a47        hyperledger/fabric-orderer            "orderer"                14 minutes ago      Up 14 minutes       0.0.0.0:7050->7050/tcp                                                      orderer.example.com

上面三个dev开头的容器是三个链码容器，一个fabric-tools充当客户端cli, 4个fabric-peer， 一个fabric-order提供节点共识服务。

接下里我们执行：docker exec -it cli bash  进入cli容器，进行操作测试：

在example02上面已经对a进行了初始化，所以我们不用再初始化了，直接进行查询：

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

root@4506e3c2130d:/opt/gopath/src/github.com/hyperledger/fabric/peer# peer chaincode query -C mychannel -n mycc -c '{"Args":["query","a"]}'
    2018-09-01 12:59:58.605 UTC [msp] GetLocalMSP -> DEBU 001 Returning existing local MSP
    2018-09-01 12:59:58.605 UTC [msp] GetDefaultSigningIdentity -> DEBU 002 Obtaining default signing identity

    Query Result: 90
    2018-09-01 12:59:58.614 UTC [main] main -> INFO 007 Exiting.....

查询的结果是：Query Result: 90 说明a现在有90元

下面我们做一个交易，a向b转账20元。

然后再查询a账户的余额

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

可以看到a的余额现在是70 a已经像b账户转了20元，通过exit来退出该容器。

至此，例子和环境都成功了。最后执行bash network\_setup.sh down， 进行网络的关闭和清理。

我写这个的时候刚刚学习fabric，写的也许很乱，等我再深入的了解以后也许会再梳理一遍，感谢网上大神的资料。
