这是我搭建的fabric的网络拓扑

3 个 orderer 节点；组织 org1 , org1 下有两个 peer 节点， peer0 和 peer1; 组织 org2 , org2 下有两个 peer 节点， peer0 和 peer1;
以上是我的多机环境的网络拓扑，使用的是docker搭建的。我的网络已经搭建成功，这里主要记录一下多机环境下合约部署与交互的操作，因为是用虚拟机搭建，有时候关机后需要重启dcoek节点，然后创建通道部署链码。关于config和docker-compose的yaml文件不知道怎么部署的可以私信我哦，多机生产网络的搭建有太多的坑了。

1. 启动网络

在两台机器上启动网络
docker-compose -f docker-compose-up.yaml up -d
可以看到我的所有节点都已经起来了，三个orderer，两个组织每个组织包含两个peer节点。

2. 创建通道并加入

2.1 虚拟机1创建通道并加入

进⼊ cli1容器，也就是以 peer0.org1 的⾓⾊与⽹络交互

docker exec -it cli1 bash 

创建通道

peer channel create -o orderer0.example.com:7050 -c mychannel -f ./channel-artifacts/channel.tx --tls true --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer0.example.com/msp/tlscacerts/tlsca.example.com-cert.pem

组织1 的 peer0 节点加⼊通道 mychannel

peer channel join -b mychannel.block

更新 组织1 的锚节点

peer channel update -o orderer0.example.com:7050 -c mychannel -f ./channel-artifacts/Org1MSPanchors.tx --tls --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer0.example.com/msp/tlscacerts/tlsca.example.com-cert.pem 

退出 cli1 容器，从 cli1 容器中拷⻉出 mychannel.block ⽂件到 multiple-deployment ⽂件夹下，并复制到 虚拟机2 中

exit docker cp cli1:/opt/gopath/src/github.com/hyperledger/fabric/peer/mychannel.block ./ 
scp -r mychannel.block org2@192.168.5.112:/home/org2/go/src/github.com/hyperledger/fabric-samples/multiple-deployment

查看虚拟机2是否收到：

2.2 虚拟机2加入通道

将 mychannel.block 拷⻉到 虚拟机2 的 cli1 （ 组织2 的 peer0 ⾓⾊）容器中

docker cp mychannel.block cli1:/opt/gopath/src/github.com/hyperledger/fabric/peer/

进⼊ cli1 容器

docker exec -it cli1 bash 
ls

加入通道：

peer channel join -b mychannel.block 

更新组织 2 的锚节点（主节点）

peer channel update -o orderer0.example.com:7050 -c mychannel -f ./channel-artifacts/Org2MSPanchors.tx --tls --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer0.example.com/msp/tlscacerts/tlsca.example.com-cert.pem

3. 安装调用智能合约

安装的同样是basic链码，在前面对这个链码介绍过，当时在测试网络中进行了部署调用，有兴趣的可以去看看对于合约的讲解。博文

3.1 安装链码

首先是虚拟机1的操作：

# 进入容器
docker exec -it cli1 bash 
# 打包链码
peer lifecycle chaincode package mycc.tar.gz --path ../../multiple-deployment/chaincode/go/basic --lang golang --label mycc_1 

# 安装链码 安装需要在两个组织都安装，现在只是在虚拟机1
peer lifecycle chaincode install mycc.tar.gz
#控制台信息：
root@b63202ddd2b5:/opt/gopath/src/github.com/hyperledger/fabric/peer# peer lifecycle chaincode install mycc.tar.gz
2023-11-15 02:11:26.585 UTC 0001 INFO [cli.lifecycle.chaincode] submitInstallProposal -> Installed remotely: response:<status:200 payload:"\nGmycc_1:c6ad224cdefc5e53bc261bb6b1fbed12b789225105f59373869b533067c9b009\022\006mycc_1" > 
2023-11-15 02:11:26.587 UTC 0002 INFO [cli.lifecycle.chaincode] submitInstallProposal -> Chaincode code package identifier: mycc_1:c6ad224cdefc5e53bc261bb6b1fbed12b789225105f59373869b533067c9b009

注意合约的这个id后面要用

mycc_1:c6ad224cdefc5e53bc261bb6b1fbed12b789225105f59373869b533067c9b009

退出 cli1 容器，将打包的链码 mycc.tar.gz 从 cli1 容器中提取出来，并拷⻉到 虚拟机2的 multiple-deployment ⽬录下

exit 
docker cp cli1:/opt/gopath/src/github.com/hyperledger/fabric/peer/mycc.tar.gz ./
scp -r mycc.tar.gz org2@192.168.5.112:/home/org2/go/src/github.com/hyperledger/fabric-samples/multiple-deployment

在虚拟机2查看我们已经收到了发送的打包后的链码
接下来是虚拟机2的操作

退出 cli1 容器，将 multiple-deployment ⽬录下的链码压缩包 mycc.tar.gz 复制到 cli1 （ 组织2 的 peer0 ）容器中

exit 
docker cp mycc.tar.gz cli1:/opt/gopath/src/github.com/hyperledger/fabric/peer/
# 进入容器查看
docker exec -it cli1 bash 
ls

安装链码

peer lifecycle chaincode install mycc.tar.gz 

两个组织都已经安装了链码，链码的id应该是一样的：mycc_1:c6ad224cdefc5e53bc261bb6b1fbed12b789225105f59373869b533067c9b009

3.2 授权与提交链码

虚拟机1，再次进⼊ cli1 容器，同意提交链码

docker exec -it cli1 bash 
peer lifecycle chaincode approveformyorg --channelID mychannel --name mycc --version 1.0 --init-required --package-id mycc_1:c6ad224cdefc5e53bc261bb6b1fbed12b789225105f59373869b533067c9b009 --sequence 1 --tls true --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer0.example.com/msp/tlscacerts/tlsca.example.com-cert.pem 

虚拟机2，进⼊ cli1 容器，同意提交链码

peer lifecycle chaincode approveformyorg --channelID mychannel --name mycc --version 1.0 --init-required --package-id mycc_1:c6ad224cdefc5e53bc261bb6b1fbed12b789225105f59373869b533067c9b009 --sequence 1 --tls true --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer0.example.com/msp/tlscacerts/tlsca.example.com-cert.pem 

虚拟机1：

查看链码状态是否就绪

peer lifecycle chaincode checkcommitreadiness --channelID mychannel --name mycc --version 1.0 --init-required --sequence 1 --tls true --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer0.example.com/msp/tlscacerts/tlsca.example.com-cert.pem --output json

提交链码

peer lifecycle chaincode commit -o orderer0.example.com:7050 --channelID mychannel --name mycc --version 1.0 --sequence 1 --init-required --tls true --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer0.example.com/msp/tlscacerts/tlsca.example.com-cert.pem --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:7051 --tlsRootCertFiles /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt 

3.3 与网络进行交互(合约的调用)

3.3.1 初始链码 – 虚拟机1

peer chaincode invoke -o orderer0.example.com:7050 --isInit --tls true --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer0.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:7051 --tlsRootCertFiles /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt -c '{"Args":["InitLedger"]}' --waitForEvent

对应的就是完成了下面的代码的功能

我们对账本进行了初始化，并且是在虚拟机1上的操作，现在想要验证一下虚拟机1的操作有没有在网络中进行同步，可以在虚拟机2上查看现在账本上的所有资产，是否是刚才初始化的那些资产。

3.3.2 在虚拟机2上查看一下当前的所有资产

进入容器后

peer chaincode invoke -o orderer0.example.com:7050 --tls true --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer0.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:7051 --tlsRootCertFiles /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt -c '{"Args":["GetAllAssets"]}' --waitForEvent# 控制台输出的资产
{\"AppraisedValue\":300,\"Color\":\"blue\",\"ID\":\"asset1\",\"Owner\":\"Tomoko\",\"Size\":5},{\"AppraisedValue\":400,\"Color\":\"red\",\"ID\":\"asset2\",\"Owner\":\"Brad\",\"Size\":5},{\"AppraisedValue\":500,\"Color\":\"green\",\"ID\":\"asset3\",\"Owner\":\"Jin Soo\",\"Size\":10},{\"AppraisedValue\":600,\"Color\":\"yellow\",\"ID\":\"asset4\",\"Owner\":\"Max\",\"Size\":10},{\"AppraisedValue\":700,\"Color\":\"black\",\"ID\":\"asset5\",\"Owner\":\"Adriana\",\"Size\":15},{\"AppraisedValue\":800,\"Color\":\"white\",\"ID\":\"asset6\",\"Owner\":\"Michel\",\"Size\":15}

通过结果得知，现在我们的操作已经在网络中同步了。

3.3.3 创建一个资产

创建资产CreateAsset(id string, color string, size int, owner string, appraisedValue int）

peer chaincode invoke -o orderer0.example.com:7050 --tls true --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer0.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:7051 --tlsRootCertFiles /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt -c '{"Args":["CreateAsset","asset7","red","15","Guandw","1000"]}' --waitForEvent 

3.3.4 查看资产

peer chaincode invoke -o orderer0.example.com:7050 --tls true --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer0.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:7051 --tlsRootCertFiles /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt -c '{"Args":["GetAllAssets"]}' --waitForEvent 

{“AppraisedValue”:300,“Color”:“blue”,“ID”:“asset1”,“Owner”:“Tomoko”,“Size”:5},{“AppraisedValue”:400,“Color”:“red”,“ID”:“asset2”,“Owner”:“Brad”,“Size”:5},
{“AppraisedValue”:500,“Color”:“green”,“ID”:“asset3”,“Owner”:“Jin Soo”,“Size”:10},{“AppraisedValue”:600,“Color”:“yellow”,“ID”:“asset4”,“Owner”:“Max”,“Size”:10},{“AppraisedValue”:700,“Color”:“black”,“ID”:“asset5”,“Owner”:“Adriana”,“Size”:15},{“AppraisedValue”:800,“Color”:“white”,“ID”:“asset6”,“Owner”:“Michel”,“Size”:15},
{\"AppraisedValue\":1000,\"Color\":\"red\",\"ID\":\"asset7\",\"Owner\":\"Guandw\",\"Size\":15}

通过结果我们在虚拟机2创建资产，然后再虚拟机1查看所有资产一样可以看到虚拟机2的操作在网络中同步了。我们的网络搭建也是没有问题的。

4. 关闭网络

如果要结束⽹络，可以在退出 cli1容器 后使⽤以下指令退出

docker-compose -f docker-compose-up.yaml down

如果需要清空容器的volume的话执行，慎重因为清空后无法重启，一般是用来格式化，重新启动容器创建通道

docker system df 
docker volume rm $(docker volume ls -qf dangling=true)
