如何配置多个锚点

Question

我从 this site 了解到一个频道上的每个成员可以有多个锚点以防止 SPOF。

我想在 fabcar-demo 中尝试多个锚节点。

请告诉我如何配置多个锚点。

为了每个组织有多个锚节点，您需要使用 configtx.yaml 配置它，例如您应该将新的锚点添加到以下部分：

Organizations:

    - &Org1
        # DefaultOrg defines the organization which is used in the sampleconfig
        # of the fabric.git development environment
        Name: Org1MSP

        # ID to load the MSP definition as
        ID: Org1MSP

        MSPDir: crypto-config/peerOrganizations/org1.example.com/msp

        AnchorPeers:
            # AnchorPeers defines the location of peers which can be used
            # for cross org gossip communication.  Note, this value is only
            # encoded in the genesis block in the Application section context
            - Host: peer0.org1.example.com
              Port: 7051
            - Host: peer1.org1.example.com
              Port: 7051


    - &Org2
        # DefaultOrg defines the organization which is used in the sampleconfig
        # of the fabric.git development environment
        Name: Org2MSP

        # ID to load the MSP definition as
        ID: Org2MSP

        MSPDir: crypto-config/peerOrganizations/org2.example.com/msp

        AnchorPeers:
            # AnchorPeers defines the location of peers which can be used
            # for cross org gossip communication.  Note, this value is only
            # encoded in the genesis block in the Application section context
            - Host: peer0.org2.example.com
              Port: 7051
            - Host: peer1.org2.example.com
              Port: 7051

这将为每个组织定义两个锚点。接下来，您需要使用 configtxgen 来生成配置更新事务，以包括两个组织的锚点：

configtxgen -profile TwoOrgsChannel -channelID mychannel -outputAnchorPeersUpdate=Org1MSPanchors.tx -asOrg=Org1MSP
configtxgen -profile TwoOrgsChannel -channelID mychannel -outputAnchorPeersUpdate=Org2MSPanchors.tx -asOrg=Org2MSP

要更新频道运行:

# updating anchors for Org1
CORE_PEER_ADDRESS=peer0.org.example.com peer channel update -f Org1MSPanchors.tx -c mychannel -o orderer.example.com:7050

分别反对每个组织的背书同行。
