创建通道

生成通道交易文件

configtxgen \
-profile TwoOrgsChannel \
-outputCreateChannelTx ./channel-artifacts/channel1.tx \
-channelID channel1 \
-configPath ./configtx/

创建通道区块

peer channel create \
-o localhost:7050  \
--ordererTLSHostnameOverride orderer.example.com \
-c channel1 \
-f ./channel-artifacts/channel1.tx \
--outputBlock ./channel-artifacts/channel1.block \
--tls \
--cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem

加入通道

组织1 的peer加入通道

由于我们已经以Org1管理员的身份使用peer CLI，因此让我们将Org1的Peer加入到通道中。由于Org1提交了通道创建交易，因此我们的文件系统上已经有了通道创世块。使用以下命令将Org1的Peer加入通道。

peer channel join -b ./channel-artifacts/channel1.block

环境变量CORE_PEER_ADDRESS已设置为以peer0.org1.example.com为目标。命令执行成功后将生成peer0.org1.example.com加入通道的响应：
