Fabric单机节点配置与部署

参考文档：原文地址
原文写的就非常好，我这里不过是复制粘贴然后理解了一点罢了。
看不懂的命令就去搜，
fabric命令帮助文档
这是命令帮助文档的地址，docker-compose.yaml的文件一定要理解。
授人以鱼不如授人以渔，希望对读者有所帮助，我也是刚开始学习相关知识。
下面的配置文件，我所用笔记的限制，没加太多注解，后续整理完值后，可以查看另一篇文章。

大家可以稍微看看，看不懂的地方可以在线打扰。企鹅号:2663189778

1. 单机节点概念

solo模式，该环境中只有一个排序（orderer）服务，从节点（peer）发送的消息由一个orderer进行排序和产生区块。适用于开发和测试环境

2. 部署流程

（1）创建一个文件夹SingleDemo

[root@iZ2zeb7b8tz2dskwx11e8wZ home]# mkdir SingleDemo
[root@iZ2zeb7b8tz2dskwx11e8wZ home]# cd SingleDemo/

（2）获取二进制文件

下载对应版本地址：https://github.com/hyperledger/fabric/releases/tag/v1.4.6

hyperledger-fabric-linux-amd64-1.4.6.tar.gz

#下载的文件解压，可以通过wget或curl下载，慢的话可以windows下载，ftp上传到服务器
[root@iZ2zeb7b8tz2dskwx11e8wZ fabric-samples]# cp -r bin/ /home/SingleDemo/
#查看bin目录下文件
[root@iZ2zeb7b8tz2dskwx11e8wZ SingleDemo]# cd bin/
[root@iZ2zeb7b8tz2dskwx11e8wZ bin]# ll

-rwxr-xr-x 1 root root 38595984 12月 26 18:44 peer

（3）准备生成证书和区块的配置文件

配置crypto-config.yaml文件（私钥证书配置文件）

OrdererOrgs:
  - Name: Orderer
    Domain: example.com
    Specs:
      - Hostname: orderer
PeerOrgs:
  - Name: Org1
    Domain: org1.example.com
    EnableNodeOUs: true
    Template:
      Count: 1
    Users:
      Count: 1

配置configtx.yaml文件

（4）生成公私钥和证书

[root@iZ2zeb7b8tz2dskwx11e8wZ SingleDemo]# ./bin/cryptogen generate --config=./crypto-config.yaml 
org1.example.com

（5）生成创世区块

[root@iZ2zeb7b8tz2dskwx11e8wZ SingleDemo]# mkdir channel-artifacts
[root@iZ2zeb7b8tz2dskwx11e8wZ SingleDemo]# ./bin/configtxgen -profile OneOrgsOrdererGenesis -outputBlock ./channel-artifacts/genesis.block

[root@iZ2zeb7b8tz2dskwx11e8wZ SingleDemo]# tree channel-artifacts/
channel-artifacts/
└── genesis.block

（6）生成通道配置区块

[root@iZ2zeb7b8tz2dskwx11e8wZ SingleDemo]# ./bin/configtxgen -profile OneOrgsChannel -outputCreateChannelTx ./channel-artifacts/mychannel.tx -channelID mychannel
2021-12-27 18:25:12.049 CST [common.tools.configtxgen] main -> INFO 001 Loading configuration

2021-12-27 18:25:12.077 CST [common.tools.configtxgen] doOutputChannelCreateTx -> INFO 008 Writing new channel tx

（7）准备docker配置文件

配置docker-compose-cli.yaml文件，拷贝到singlepeer目录下。

（8）准备部署智能合约

这是官方案例中的智能合约

[root@iZ2zeb7b8tz2dskwx11e8wZ fabricDemo]# cd fabric-samples/chaincode/chaincode_example02
[root@iZ2zeb7b8tz2dskwx11e8wZ chaincode_example02]# ll
total 12
drwxrwxr-x 2 root root 4096 Mar 29  2019 go
drwxrwxr-x 3 root root 4096 Mar 29  2019 java
drwxrwxr-x 2 root root 4096 Mar 29  2019 node
[root@iZ2zeb7b8tz2dskwx11e8wZ chaincode_example02]# tree go
go
└── chaincode_example02.go

将go下面的目录拷贝到SingleDemo/chaincode/go中

[root@iZ2zeb7b8tz2dskwx11e8wZ go]# clear
[root@iZ2zeb7b8tz2dskwx11e8wZ go]# cp -r  /home/fabricDemo/fabric-samples/chaincode/chaincode_example02/go/chaincode_example02.go .
[root@iZ2zeb7b8tz2dskwx11e8wZ go]# tree
.
└── chaincode_example02.go

（9）启动fabric网络

启动orderer和peer

[root@iZ2zeb7b8tz2dskwx11e8wZ SingleDemo]# docker-compose -f docker-compose-cli.yaml up -d
Creating network "singledemo_default" with the default driver
Creating orderer.example.com    ... done
Creating peer0.org1.example.com ... done
Creating cli                    ... done

启动cli容器

[root@iZ2zeb7b8tz2dskwx11e8wZ SingleDemo]# docker exec -it  cli /bin/bash
root@7246881c69b6:/opt/gopath/src/github.com/hyperledger/fabric/peer#

创建channel

peer channel create -o orderer.example.com:7050 -c mychannel -f ./channel-artifacts/mychannel.tx

Peer加入Channel

peer channel join -b mychannel.block

（10）安装智能合约

安装智能合约

peer chaincode install -n mycc -p github.com/hyperledger/fabric/singlepeer/chaincode/go -v 1.0

#这里安装可能会出点问题，可能是镜像挂载没设置好，对应的go的智能合约
#在go目录下，这个-p 直到 go就可以了。具体查看cli中的peer命令，希望读者能自己动手解决


root@5d08bf1c1ba8://opt/gopath/src/github.com/hyperledger/fabric/peer# peer chaincode install -n mycc -p github.com/hyperledger/fabric/singlepeer/chaincode/go  -v 1.0

2021-12-28 04:28:21.789 UTC [chaincodeCmd] install -> INFO 005 Installed remotely response:<status:200 payload:"OK" >

实例化智能合约

peer chaincode instantiate -o orderer.example.com:7050 -C mychannel -n mycc -v 1.0 -c '{"Args":["init","a","100","b","200"]}' -P "AND ('Org1MSP.peer')"
#就是创建a和b的账户

#这里也有点问题，会提示
Error: could not assemble transaction, err proposal response was not successful, error code 500, msg error starting container: error starting container: API error (404): network singlepeer_default not found

#这是因为docker-compose.yaml配置文件的问题

- CORE_VM_DOCKER_HOSTCONFIG_NETWORKMODE=singlepeer_default

peer chaincode query -C mychannel -n mycc -c '{"Args":["query","a"]}'
#查询A，可以查到100的数据
