1 创建通道
网络搭建完成之后就可以开始创建通道了。Fabric V2.5.4中可以在不创建系统通道的情况下直接创建应用通道。
1.1 修改配置文件
先创建配置文件configtx.yaml。可以直接将fabric-samples/test-network/configtx/configtx.yaml文件复制到目录finance_network下然后在这个文件上进行修改即可。 修改后的configtx.yaml文件内容如下(主要修改MSP和TLS相关的内容)
Organizations:- OrdererOrgName: OrdererOrgID: OrdererMSP#注意修改MSPDir: ./organizations/ordererOrganizations/finance.com/mspPolicies:Readers:Type: SignatureRule: OR(OrdererMSP.member)Writers:Type: SignatureRule: OR(OrdererMSP.member)Admins:Type: SignatureRule: OR(OrdererMSP.admin)OrdererEndpoints:- orderer.finance.com:7050- Org1Name: Org1MSPID: Org1MSPMSPDir: ./organizations/peerOrganizations/org1.finance.com/mspPolicies:Readers:Type: SignatureRule: OR(Org1MSP.admin, Org1MSP.peer, Org1MSP.client)Writers:Type: SignatureRule: OR(Org1MSP.admin, Org1MSP.client)Admins:Type: SignatureRule: OR(Org1MSP.admin)Endorsement:Type: SignatureRule: OR(Org1MSP.peer)- Org2Name: Org2MSPID: Org2MSPMSPDir: ./organizations/peerOrganizations/org2.finance.com/mspPolicies:Readers:Type: SignatureRule: OR(Org2MSP.admin, Org2MSP.peer, Org2MSP.client)Writers:Type: SignatureRule: OR(Org2MSP.admin, Org2MSP.client)Admins:Type: SignatureRule: OR(Org2MSP.admin)Endorsement:Type: SignatureRule: OR(Org2MSP.peer)Capabilities:Channel: ChannelCapabilitiesV2_0: trueOrderer: OrdererCapabilitiesV2_0: trueApplication: ApplicationCapabilitiesV2_5: trueApplication: ApplicationDefaultsOrganizations:Policies:Readers:Type: ImplicitMetaRule: ANY ReadersWriters:Type: ImplicitMetaRule: ANY WritersAdmins:Type: ImplicitMetaRule: MAJORITY AdminsLifecycleEndorsement:Type: ImplicitMetaRule: MAJORITY EndorsementEndorsement:Type: ImplicitMetaRule: MAJORITY EndorsementCapabilities:: *ApplicationCapabilitiesOrderer: OrdererDefaultsAddresses:- orderer.finance.com:7050BatchTimeout: 2sBatchSize:MaxMessageCount: 10AbsoluteMaxBytes: 99 MBPreferredMaxBytes: 512 KBOrganizations:Policies:Readers:Type: ImplicitMetaRule: ANY ReadersWriters:Type: ImplicitMetaRule: ANY WritersAdmins:Type: ImplicitMetaRule: MAJORITY AdminsBlockValidation:Type: ImplicitMetaRule: ANY WritersChannel: ChannelDefaultsPolicies:Readers:Type: ImplicitMetaRule: ANY ReadersWriters:Type: ImplicitMetaRule: ANY WritersAdmins:Type: ImplicitMetaRule: MAJORITY AdminsCapabilities:: *ChannelCapabilities

使用如下命令创建应用通道。
#先回到finance_network目录下
configtxgen -profile ChannelUsingRaft -outputBlock ./channel-artifacts/channel1.block -channelID channel1执行结果如下 Tips:在执行这条命令的时候要保证环境变量FABRIC_CFG_PATH为空值若不为空需要使用-configPath参数指定configtx.yaml文件的地址。
2 添加节点
通道创建完成后需要将orderer节点和peer节点加入都通道中。
2.1 添加orderer节点
可以使用osnadmin命令将orderer节点添加到通道上具体如下
#先跳转到finance_network目录下
#设置变量
export ORDERER_CA$PWD/organizations/ordererOrganizations/finance.com/orderers/orderer.finance.com/msp/tlscacerts/tlsca.finance.com-cert.pem
export ORDERER_ADMIN_TLS_SIGN_CERT$PWD/organizations/ordererOrganizations/finance.com/orderers/orderer.finance.com/tls/server.crt
export ORDERER_ADMIN_TLS_PRIVATE_KEY$PWD/organizations/ordererOrganizations/finance.com/orderers/orderer.finance.com/tls/server.key
#添加节点
osnadmin channel join --channelID channel1 --config-block ./channel-artifacts/channel1.block -o localhost:7053 --ca-file $ORDERER_CA --client-cert $ORDERER_ADMIN_TLS_SIGN_CERT --client-key $ORDERER_ADMIN_TLS_PRIVATE_KEY命令执行成功则提示 如果在执行osnadmin join命令是提示listen tcp:lookup localhost:7053 on 127.0.0.11:53 no such host一般是因为CCP没有设置或CCP文件中有错误。
2.2 添加peer节点
这里一共有3个peer节点要添加到通道上这里仅以peer0.org1.finance.com为例进行说明。具体如下
#先跳转到finance_network目录下
#将peer命令绑到peer0.org1.finance.com节点上
export CORE_PEER_TLS_ENABLEDtrue
export CORE_PEER_LOCALMSPIDOrg1MSP
export CORE_PEER_TLS_ROOTCERT_FILE$PWD/organizations/peerOrganizations/org1.finance.com/peers/peer0.org1.finance.com/tls/ca.crt
export CORE_PEER_MSPCONFIGPATH$PWD/organizations/peerOrganizations/org1.finance.com/users/Adminorg1.finance.com/msp
export CORE_PEER_ADDRESSlocalhost:7051
export FABRIC_CFG_PATH$PWD/config
#执行添加命令
peer channel join -b ./channel-artifacts/channel1.block执行成功时结果如下
3 设置锚节点
Fabric网络中的锚节点(Anchor Peer)是网络中的一个特殊节点其作用如下
组织连接锚节点用于建立和维护该组织与其他组织之间的连接。其他组织可以通过与锚节点通信来了解该组织的组织配置。路由策略锚节点负责维护和分发组织的路由策略。路由策略定义了网络中各个组织的Peer节点和Orderer节点的位置信息以便其他组织可以正确地将交易请求发送给目标节点。组织配置更新当该组织的组织配置发生更改时锚节点会更新最新的组织配置块并将其广播给其他节点。这确保了网络中的所有节点都能够得到最新的组织配置并保持同步。
在通道配置信息中包含了每个组织的锚节点信息每个通道都可以通过使用configtxlator工具来更新通道的方式来给每个组织设置锚节点。这里仅以Org1为例进行说明。这里将peer0.org1.finance.com节点设置为组织Org1的锚节点。
先将peer CLI关联到peer0.org1.finance.com节点上设置如下环境变量
export CORE_PEER_TLS_ENABLEDtrue
export CORE_PEER_LOCALMSPIDOrg1MSP
export CORE_PEER_TLS_ROOTCERT_FILE$PWD/organizations/peerOrganizations/org1.finance.com/peers/peer0.org1.finance.com/tls/ca.crt
export CORE_PEER_MSPCONFIGPATH$PWD/organizations/peerOrganizations/org1.finance.com/users/Adminorg1.finance.com/msp
export CORE_PEER_ADDRESSlocalhost:7051
export FABRIC_CFG_PATH$PWD/config获取通道原始配置信息(这里要注意检查ORDERER_CA的值还在不在)
peer channel fetch config channel-artifacts/config_block.pb -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com -c channel1 --tls --cafile $ORDERER_CA代码执行结果如下
将通道配置信息转化成json串并使用jq工具将json串转化为流式串
#先进入channel-artifacts目录
configtxlator proto_decode --input config_block.pb --type common.Block --output config_block.json
jq .data.data[0].payload.data.config config_block.json config.json使用jq工具将Org1组织的锚节点信息添加到modified_config.json
cp config.json config_copy.json
jq .channel_group.groups.Application.groups.Org1MSP.values {AnchorPeers:{mod_policy: Admins,value:{anchor_peers: [{host: peer0.org1.example.com,port: 7051}]},version: 0}} config_copy.json modified_config.json将config.json和modified_config.json转化成pb文件并计算两者之间的差异。
configtxlator proto_encode --input config.json --type common.Config --output config.pb
configtxlator proto_encode --input modified_config.json --type common.Config --output modified_config.pb
configtxlator compute_update --channel_id channel1 --original config.pb --updated modified_config.pb --output config_update.pb更新通道配置
configtxlator proto_decode --input config_update.pb --type common.ConfigUpdate --output config_update.json
echo {payload:{header:{channel_header:{channel_id:channel1, type:2}},data:{config_update:$(cat config_update.json)}}} | jq . config_update_in_envelope.json
configtxlator proto_encode --input config_update_in_envelope.json --type common.Envelope --output config_update_in_envelope.pb
cd ..
peer channel update -f channel-artifacts/config_update_in_envelope.pb -c channel1 -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --tls --cafile $PWD/organizations/ordererOrganizations/finance.com/orderers/orderer.finance.com/msp/tlscacerts/tlsca.finance.com-cert.pem4 其他
从2.1和2.2两部分需要频繁的设置环境变量尤其是当需要添加的peer节点越多时整个过程比较繁琐并且容易出错。并且给组织添加锚节点的时候也需要执行很多命令。这里参考fabric-sample/test-network中的方法使用bash文件来完成节点的添加及锚节点的设置。 添加orderer节点 在fabric_network目录下创建scripts/OrdererEnv.sh文件其内容如下
channel_name$1
host_name$2
orderer_port$3export ORDERER_CA$PWD/organizations/ordererOrganizations/${host_name}.com/orderers/orderer.${host_name}.com/msp/tlscacerts/tlsca.${host_name}.com-cert.pem
export ORDERER_ADMIN_TLS_SIGN_CERT$PWD/organizations/ordererOrganizations/${host_name}.com/orderers/orderer.${host_name}.com/tls/server.crt
export ORDERER_ADMIN_TLS_PRIVATE_KEY$PWD/organizations/ordererOrganizations/${host_name}.com/orderers/orderer.${host_name}.com/tls/server.keyosnadmin channel join --channelID ${channel_name} --config-block ./channel-artifacts/${channel_name}.block -o localhost:$(expr $orderer_port) --ca-file $ORDERER_CA --client-cert $ORDERER_ADMIN_TLS_SIGN_CERT --client-key $ORDERER_ADMIN_TLS_PRIVATE_KEY其命令执行结果如下 添加peer节点 在fabric_network目录下创建scripts/PeerEnv.sh文件其内容如下
channel_name$1
host_name$2
peer_port$3
peer_num$4
org_num$5
org_msp$6export FABRIC_CFG_PATH$PWD/config

export CORE_PEER_MSPCONFIGPATH$PWD/organizations/peerOrganizations/org${org_num}.${host_name}.com/users/Adminorg${org_num}.${host_name}.com/msp
export CORE_PEER_ADDRESSlocalhost:$(expr $peer_port)其执行结果如下 Tips:但要注意这种方法设置的环境变量仅在执行语句时有效所以语句执行结束后不能运行peer channel list命令。 设置锚节点 在fabric_network目录下创建scripts/SetAnchorPeer.sh文件其内容如下
