通过configtxgen工具来读取configtx.yaml文件的配置:

• 为orderer service生成genesis.block
• 生成channel相关的transaction文件channel.tx。
• 更新Org1MSP的anchor peer
• 更新Org2MSP的anchor peer

根据配置的channel名字，创建channel。创建channel的时候，需要指定orderer地址、channel.tx文件的位置、是否启用tls以及orderer证书的位置。

创建channel的命令：

peer channel create -o orderer的地址及端口号 -c channel名字 -f ./channel-artifacts/channel.tx --tls true --cafile orderer证书的位置

1. 安装chaincode

Installing chaincode on peer0.org1...
+ peer chaincode install -n mycc -v 1.0 -l golang -p github.com/chaincode/chaincode_example02/go/
+ res=0
+ set +x
2018-08-06 02:33:29.903 UTC [chaincodeCmd] checkChaincodeCmdParams -> INFO 001 Using default escc
2018-08-06 02:33:29.903 UTC [chaincodeCmd] checkChaincodeCmdParams -> INFO 002 Using default vscc
2018-08-06 02:33:30.053 UTC [chaincodeCmd] install -> INFO 003 Installed remotely response:
===================== Chaincode is installed on peer0.org1 =====================

Install chaincode on peer0.org2...
+ peer chaincode install -n mycc -v 1.0 -l golang -p github.com/chaincode/chaincode_example02/go/
+ res=0
+ set +x
2018-08-06 02:33:30.119 UTC [chaincodeCmd] checkChaincodeCmdParams -> INFO 001 Using default escc
2018-08-06 02:33:30.119 UTC [chaincodeCmd] checkChaincodeCmdParams -> INFO 002 Using default vscc
2018-08-06 02:33:30.269 UTC [chaincodeCmd] install -> INFO 003 Installed remotely response:
===================== Chaincode is installed on peer0.org2 =====================

安装chaincode时可以指定：

• -n : chaincode name
• -v : chaincode版本。(chaincode 可以升级)
• -l : chaincode使用哪种语言编写的。
• -p ：chaincode 所在的路径。(cli容器中的路径)

这里安装chaincode时需要安装到你指定的anchor peer上。在安装过程中，系统链码会对你的chaincode进行校验escc、vscc

命令：

+ peer chaincode install -n chaincode的名字 -v chaincode的版本 -l 编写chaincode的语言 -p chaincode在cli容器中的路径

1. 实例化chaincode

Instantiating chaincode on peer0.org2...
+ peer chaincode instantiate -o orderer.example.com:7050 --tls true --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C mychannel -n mycc -l golang -v 1.0 -c '{"Args":["init","a","100","b","200"]}' -P 'AND ('\''Org1MSP.peer'\'','\''Org2MSP.peer'\'')'
+ res=0
+ set +x
2018-08-06 02:33:30.341 UTC [chaincodeCmd] checkChaincodeCmdParams -> INFO 001 Using default escc
2018-08-06 02:33:30.342 UTC [chaincodeCmd] checkChaincodeCmdParams -> INFO 002 Using default vscc
===================== Chaincode is instantiated on peer0.org2 on channel 'mychannel' =====================

实例化chaincode时，需要指定：

• -o : orderer节点的地址
• --tls : 是否启用tls。true/false
• -- cafile : orderer证书的位置。(启用tls时需要指定)
• -C : channel 名字
• -n : chaincode名字
• -l : chaincode编写的语言
• -v：chaincode版本
• -c : 初始化时的参数
• -P : 背书策略

在实例化链码的时候，系统的escc和vscc链码会对你的链码进行验证。
命令：

peer chaincode instantiate -o 排序节点的地址 --tls 是否启用tls --cafile 排序节点的证书地址 -C 通道名称 -n 链码名称 -l 链码使用的语言 -v 链码的版本 -c 初始化时传入的参数 -P 背书策略

1. 查询chain code

===================== Querying on peer0.org1 on channel 'mychannel'... =====================
Attempting to Query peer0.org1 ...3 secs
+ peer chaincode query -C mychannel -n mycc -c '{"Args":["query","a"]}'
+ res=0
+ set +x

100
===================== Query successful on peer0.org1 on channel 'mychannel' =====================

查询链码时需要指定：

• -C : 通道名字
• -n : 链码名字
• -c : 参数
  命令：

peer chaincode query -C 通道名字 -n 链码名字 -c 参数

1. 调用链码

Sending invoke transaction on peer0.org1 peer0.org2...
+ peer chaincode invoke -o orderer.example.com:7050 --tls true --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C mychannel -n mycc --peerAddresses peer0.org1.example.com:7051 --tlsRootCertFiles /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt --peerAddresses peer0.org2.example.com:7051 --tlsRootCertFiles /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt -c '{"Args":["invoke","a","b","10"]}'
+ res=0

2018-08-06 02:34:01.345 UTC [chaincodeCmd] chaincodeInvokeOrQuery -> INFO 001 Chaincode invoke successful. result: status:200
===================== Invoke transaction successful on peer0.org1 peer0.org2 on channel 'mychannel' =====================

调用链码时需要指定：

• -o : orderer的地址
• --tls：是否启用tls。true/false非必填
• --cafile: orderer的证书位置。(如果tls为 true 则为必填项。)
• -C : 通道名称
• -n ：链码名称
• --peerAddresses ：peer节点的地址 (可以指定多个节点)
• --tlsRootCertFiles : peer节点的tls证书地址 （根据peerAddresses来进行配置）
• -c : 参数

命令：

peer chaincode invoke -o orderer节点的地址 --tls 是否启用 --cafile orderer节点的证书 -C 通道名称 -n 链码名称 --peerAddresses peer节点的地址 --tlsRootCertFiles peer节点对应的tls证书地址  -c 参数

总结

在启动first-network网络的过程中我们可以总结为以下几个过程

1. 通过cryptogen读取crypto-config.yaml文件的配置，生成证书相关的内容。
2. 通过configtxgen工具来读取configtx.yaml文件的配置，生成启动网络的基本环境。
3. 创建channel

peer channel create -o orderer的地址及端口号 -c channel名字 -f ./channel-artifacts/channel.tx --tls true --cafile orderer证书的位置

1. 将节点加入通道

peer channel join -b 通道名称.block

1. 更新anchor peer

peer channel update -o orderer的地址及端口号 -c channel名字 -f ./channel-artifacts/Org1MSPanchors.tx --tls true --cafile 
orderer证书的位置

1. 安装链码

peer chaincode install -n chaincode的名字 -v chaincode的版本 -l 编写chaincode的语言 -p chaincode在cli容器中的路径

1. 实例化链码

peer chaincode instantiate -o 排序节点的地址 --tls 是否启用tls --cafile 排序节点的证书地址 -C 通道名称 -n 链码名称 -l 链码使用的语言 -v 链码的版本 -c 初始化时传入的参数 -P 背书策略

1. 查询链码
