前面我们使用单机部署的方式将fabric1.0的基本流程全部调通了。这次我们玩一次分布式多机部署的游戏。将Fabric-E2E=1orderer+4peer部署到五台不同的主机上。并实现智能合约的操作。
主机名 | ip | 角色 |
---|---|---|
orderer.example.com | 39.108.219.98 | orderer排序服务器 |
peer0.org1.example.com | 120.78.167.221 | peer1节点 |
peer1.org1.example.com | 120.79.169.213 | peer2节点 |
peer0.org2.example.com | 47.106.127.24 | peer3节点 |
peer1.org2.example.com | 47.98.143.199 | peer4节点 |
cd $GOPATH/src/github.com/hyperledger/fabric/examples/e2e_cli/
./network_setup.sh down(已经启动的话、或者不知道有没有启动)
./network_setup.sh up
公私钥和证书是用于Server和Server之间的安全通信,另外要创建Channel并让其他节点加入Channel就需要创世区块,这些必备文件都可以一个命令生成,官方已经给出了脚本
./generateArtifacts.sh mychannel
运行这个命令后,系统会创建channel-artifacts文件夹,里面包含了mychannel这个通道相关的文件,另外还有一个crypto-config文件夹,里面包含了各个节点的公私钥和证书的信息。
cp docker-compose-cli.yaml docker-compose-peer.yaml
然后修改docker-compose-peer.yaml,去掉orderer的配置,只保留一个peer和cli,因为我们要多级部署,节点与节点之前又是通过主机名通讯,所以需要修改容器中的host文件,也就是extra_hosts设置,修改后的peer配置如下:
version: '2'
services:
peer0.org1.example.com:
container_name: peer0.org1.example.com
extends:
file: base/docker-compose-base.yaml
service: peer0.org1.example.com
extra_hosts:
- "orderer.example.com:39.108.219.98"
同样,cli也需要能够和各个节点通讯,所以cli下面也需要添加extra_hosts设置,去掉无效的依赖,并且去掉command这一行,因为我们是每个peer都会有个对应的客户端,也就是cli,所以我只需要去手动执行一次命令,而不是自动运行。修改后的cli配置如下:
cli:
container_name: cli
image: hyperledger/fabric-tools
tty: true
environment:
- GOPATH=/opt/gopath
- CORE_VM_ENDPOINT=unix:///host/var/run/docker.sock
- CORE_LOGGING_LEVEL=DEBUG
- CORE_PEER_ID=cli
- CORE_PEER_ADDRESS=peer0.org1.example.com:7051
- CORE_PEER_LOCALMSPID=Org1MSP
- CORE_PEER_TLS_ENABLED=false
- CORE_PEER_TLS_CERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/server.crt
- CORE_PEER_TLS_KEY_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/server.key
- CORE_PEER_TLS_ROOTCERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt
- CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/users/Admin@org1.example.com/msp
- GODEBUG=netdns=go
working_dir: /opt/gopath/src/github.com/hyperledger/fabric/peer
volumes:
- /var/run/:/host/var/run/
- ../chaincode/go/:/opt/gopath/src/github.com/hyperledger/fabric/examples/chaincode/go
- ./crypto-config:/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/
- ./scripts:/opt/gopath/src/github.com/hyperledger/fabric/peer/scripts/
- ./channel-artifacts:/opt/gopath/src/github.com/hyperledger/fabric/peer/channel-artifacts
depends_on:
- peer0.org1.example.com
extra_hosts:
- "orderer.example.com:39.108.219.98"
- "peer0.org1.example.com:120.78.167.221"
- "peer1.org1.example.com:120.79.169.213"
- "peer0.org2.example.com:47.106.127.24"
- "peer1.org2.example.com:47.98.143.199"
在单击模式下,4个peer会映射主机不同的端口,但是我们在多机部署的时候是不需要映射不同端口的,所以需要修改base/docker-compose-base.yaml文件,将所有peer的端口映射都改为相同的:
ports:
- 7051:7051
- 7052:7052
- 7053:7053
cp docker-compose-cli.yaml docker-compose-orderer.yaml
version: '2'
services:
orderer.example.com:
extends:
file: base/docker-compose-base.yaml
service: orderer.example.com
container_name: orderer.example.com
一次性都丢到orderer的E2E目录下去
scp /Users/lantian/Downloads/fabric4+1/docker-compose-peer1.yaml root@39.108.219.98:/root/go/src/github.com/hyperledger/fabric/examples/e2e_cli/
scp /Users/lantian/Downloads/fabric4+1/docker-compose-peer2.yaml root@39.108.219.98:/root/go/src/github.com/hyperledger/fabric/examples/e2e_cli/
scp /Users/lantian/Downloads/fabric4+1/docker-compose-peer3.yaml root@39.108.219.98:/root/go/src/github.com/hyperledger/fabric/examples/e2e_cli/
scp /Users/lantian/Downloads/fabric4+1/docker-compose-peer4.yaml root@39.108.219.98:/root/go/src/github.com/hyperledger/fabric/examples/e2e_cli/
base下的yaml
scp /Users/lantian/Downloads/fabric4+1/base/docker-compose-base.yaml root@39.108.219.98:/root/go/src/github.com/hyperledger/fabric/examples/e2e_cli/base
scp /Users/lantian/Downloads/fabric4+1/base/peer-base.yaml root@39.108.219.98:/root/go/src/github.com/hyperledger/fabric/examples/e2e_cli/base
先删掉peer每台机子原本的E2E
rm -r /root/go/src/github.com/hyperledger/fabric/examples/e2e_cli/
然后从orderer上下载E2E
scp -r root@39.108.219.98:/root/go/src/github.com/hyperledger/fabric/examples/e2e_cli/ /root/go/src/github.com/hyperledger/fabric/examples
开启orderer
docker-compose -f docker-compose-orderer.yaml up -d
依次开启其余四台peer
docker-compose -f docker-compose-peer1.yaml up -d
docker-compose -f docker-compose-peer2.yaml up -d
docker-compose -f docker-compose-peer3.yaml up -d
docker-compose -f docker-compose-peer4.yaml up -d
新手第一次部署的难度会比较大,务必耐心。一定可以部署的成功。
