Fabric创建通道、组织加入通道
Fabric创建通道、加入组织
-
生成各个组织以及Orderer的证书材料（使用Fabric-CA 工具生成）
-
生成Orderer的系统通道
# myconfigtx 目录下为configtx.yaml 文件，详细内容见下 export FABRIC_CFG_PATH=${PWD}/myconfigtx # 生成的创世块的名称要与 orderer 的docker-compose 挂载的文件名一致， - ../system-genesis-block/genesis.block:/var/hyperledger/orderer/orderer.genesis.block configtxgen -profile FaddeiOrdererGenesis -channelID faddei-system-channel -outputBlock ./system-genesis-block/genesis.block
-
生成应用通道
# Faddei 为 configtx.yaml 应用通道的名称 configtxgen -profile FaddeiChannel -outputCreateChannelTx ./channel-artifacts/faddeichannel.tx -channelID faddeichannel
-
启动Peer节点及Orderer节点
docker-compose -f docker/docker-compose-ca.yaml up -d docker-compose -f docker/docker-compose-test-net.yaml up -d -
反复执行几次
docker ps -a确保所有容器正常启动，并且容器不会异常退出（如果第2步中生成的创世块的名称，跟orderer的docker-compose 挂在文件的名称不对应的话，orderer节点会挂掉），图中不含ca节点
-
切换到Org1的管理员
export CORE_PEER_TLS_ENABLED=true export CORE_PEER_LOCALMSPID="Org1MSP" export CORE_PEER_TLS_ROOTCERT_FILE=${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt export CORE_PEER_MSPCONFIGPATH=${PWD}/organizations/peerOrganizations/org1.example.com/users/Admin@org1.example.com/msp export CORE_PEER_ADDRESS=localhost:7051 export PATH=$PATH:$PWD/../bin/ export FABRIC_CFG_PATH=$PWD/../config/ export ORDERER_CA=${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -
执行
peer channel list检查，可以看到Org1 的 peer 当前尚未加入任何通道
-
最后创建通道
# 需要指定 orderer的地址， 通道名称第3步中设置的名称 faddeichannel，以及 faddeichannel.tx，orderer 的证书 peer channel create -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com -c faddeichannel -f ./channel-artifacts/faddeichannel.tx --outputBlock ./channel-artifacts/faddeichannel.block --tls --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem
-
将Peer节点加入通道，并检查是否成功
peer channel join -b ./channel-artifacts/faddeichannel.block peer channel list
-
以上为从零创建通道的步骤
以下为configtx.yaml 文件内容，其中只包括一个组织，一个Orderer节点。其他组织加入通道可通过SDK或者脚本完成

# SECTION: Capabilities
#
# - This section defines the capabilities of fabric network. This is a new
# concept as of v1.1.0 and should not be utilized in mixed networks with
# v1.0.x peers and orderers. Capabilities define features which must be
# present in a fabric binary for that binary to safely participate in the
# fabric network. For instance, if a new MSP type is added, newer binaries
# might recognize and validate the signatures from this type, while older
# binaries without this support would be unable to validate those
# transactions. This could lead to different versions of the fabric binaries
# having different world states. Instead, defining a capability for a channel
# informs those binaries without this capability that they must cease
# processing transactions until they have been upgraded. For v1.0.x if any
# capabilities are defined (including a map with all capabilities turned off)
# then the v1.0.x peer will deliberately crash.
