1、生成证书：
#路径需要更改为自己的路径
cd ~/go/src/github.com/hyperledger/fabric/scripts/fabric-samples/first-network/
#在这里可能会报错，通常是权限问题，可以添加sudo重新执行
cryptogen generate --config=./crypto-config.yaml
#执行完毕后，当前文件夹下会出现一个新的文件夹：crypto-config，在该文件夹下就是刚刚生成的证书.
2、Orderer服务 生成创世区块，通道配置，锚节点配置文件
#路径需要更改为自己的路径
cd ~/go/src/github.com/hyperledger/fabric/scripts/fabric-samples/first-network/
生成创世区块
configtxgen -profile TwoOrgsOrdererGenesis -outputBlock ./channel-artifacts/genesis.block
生成通道配置信息
export CHANNEL_NAME=mychannel
configtxgen -profile TwoOrgsChannel -outputCreateChannelTx ./channel-artifacts/channel.tx -channelID $CHANNEL_NAME
生成两个组织的锚节点配置文件
configtxgen -profile TwoOrgsChannel -outputAnchorPeersUpdate ./channel-artifacts/Org1MSPanchors.tx -channelID $CHANNEL_NAME -asOrg Org1MSP
configtxgen -profile TwoOrgsChannel -outputAnchorPeersUpdate ./channel-artifacts/Org2MSPanchors.tx -channelID $CHANNEL_NAME -asOrg Org2MSP
成功后在channel-artifacts有四个文件：
channel.tx genesis.block Org1MSPanchors.tx Org2MSPanchors.tx
-- 初始区块（genesis.block）和通道配置事务（channel.tx、Org1MSPanchors.tx..）
-profile :configtx.yaml中的Profiles配置项，用于指定生成初始区块还是通道交易配置文件。
-asOrg：用于指定有权设置的写集中的值的Org组织名称。
3、启动fabric网络
sudo docker-compose -f docker-compose-cli.yaml up -d
进入cli容器
sudo docker exec -it cli bash
4、创建通道
export CHANNEL_NAME=mychannel
export ORDERER_CA=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem
peer channel create -o orderer.example.com:7050 -c $CHANNEL_NAME -f ./channel-artifacts/channel.tx --tls true --cafile $ORDERER_CA
-o 指定Orderer节点地址
-c 指定要创建的应用通道名称
-f 指定创建应用通道时所使用的应用通道交易配置文件
--tls 开启tls验证
--cafile 指定tls_ca证书的所在路径
5、将节点加入应用通道
peer channel join -b mychannel.block
6、更新锚节点
Org1更新锚节点：
CORE_PEER_LOCALMSPID="Org1MSP"
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
CORE_PEER_ADDRESS=peer0.org1.example.com:7051
ORDERER_CA=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem
peer channel update -o orderer.example.com:7050 -c $CHANNEL_NAME -f ./channel-artifacts/Org1MSPanchors.tx --tls true --cafile $ORDERER_CA
Org2更新锚节点：
CORE_PEER_LOCALMSPID="Org2MSP"
CORE_PEER_TLS_ROOTCERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt
CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/users/Admin@org2.example.com/msp
CORE_PEER_ADDRESS=peer0.org2.example.com:7051
peer channel update -o orderer.example.com:7050 -c $CHANNEL_NAME -f ./channel-artifacts/Org2MSPanchors.tx --tls true --cafile $ORDERER_CA
7、安装示例链码
先切换到peer0.org1这个节点
CORE_PEER_LOCALMSPID="Org1MSP"
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
CORE_PEER_ADDRESS=peer0.org1.example.com:7051
使用peer chaincode install命令可以安装指定的ChainCode并对其命名：
peer chaincode install -n mycc -v 1.0 -p github.com/chaincode/chaincode_example02/go
8、实例化链码
peer chaincode instantiate -o orderer.example.com:7050 --tls true --cafile $ORDERER_CA -C $CHANNEL_NAME -n mycc -v 1.0 -c '{"Args":["init","a","100","b","200"]}' -P "OR('Org1MSP.member','Org2MSP.member')"
9、查询并发起交易
peer chaincode query -C mychannel -n mycc -c '{"Args":["query","a"]}'
在另一个节点查询交易
CORE_PEER_LOCALMSPID="Org2MSP"
CORE_PEER_TLS_ROOTCERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt
CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/users/Admin@org2.example.com/msp
CORE_PEER_ADDRESS=peer0.org2.example.com:7051
peer chaincode query -C mychannel -n mycc -c '{"Args":["query","a"]}'
10、查看日志
docker logs -f peer0.org1.example.com
