从配置文件生成证书：
../bin/cryptogen generate --config=./crypto-config-add.yaml
您在./crypto-config/peerOrganizations/org3.example.com/上获得了Org3的证书。
运行configtxlator
configtxlator工具旨在支持重新配置Fabric网络。
../bin/configtxlator start &
查询当前配置
查询cli容器的当前配置：
docker exec -it cli peer channel fetch config config_block.pb -o orderer.example.com:7050 -c mychannel --tls --cafile ./crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem
docker cp cli:/opt/gopath/src/github.com/hyperledger/fabric/peer/config_block.pb .
解码配置
使用configtxlator解码获取的配置文件：
curl -X POST --data-binary @config_block.pb http://127.0.0.1:7059/protolator/decode/common.Block > config_block.json
扩展配置部分
从解码的配置文件config中提取扩展配置部分：
jq .data.data[0].payload.data.config config_block.json > config.json
从配置部分提取Org1MSP部分：
jq .channel_group.groups.Application.groups.Org1MSP config.json > Org1MSP.json
创建新配置
基于Org1MSP.json创建Org3MSP.json文件：
ADMIN_CERT=$(cat ./crypto-config/peerOrganizations/org3.example.com/users/Admin\@org3.example.com/msp/signcerts/Admin\@org3.example.com-cert.pem |base64 |tr -d '\n')
ROOT_CERT=$(cat ./crypto-config/peerOrganizations/org3.example.com/ca/ca.org3.example.com-cert.pem |base64 |tr -d '\n')
TLS_ROOT_CERT=$(cat ./crypto-config/peerOrganizations/org3.example.com/tlsca/tlsca.org3.example.com-cert.pem |base64 |tr -d '\n')
jq --arg admin ${ADMIN_CERT} --arg root ${ROOT_CERT} --arg tls ${TLS_ROOT_CERT} '.values.MSP.value.config.admins[0] = $admin | .values.MSP.value.config.root_certs[0] = $root | .values.MSP.value.config.tls_root_certs[0] = $tls' Org1MSP.json > Org3MSP.json
sed -i 's/Org1MSP/Org3MSP/g' Org3MSP.json将Org2MSP.json的内容放在config.json文件中的Org2MSP之后：
ORG3=$(cat Org3MSP.json)
jq --argjson org3 "$ORG3" '.channel_group.groups.Application.groups.Org3MSP = $org3' config.json > updated_config.json
对原始配置和修改配置进行编码
通过configtxlatr，编码配置文件，config.json和updated_config.json：
curl -X POST --data-binary @config.json http://127.0.0.1:7059/protolator/encode/common.Config > config.pb
curl -X POST --data-binary @updated_config.json http://127.0.0.1:7059/protolator/encode/common.Config > updated_config.pb
将它们发送到configtxlator以计算配置更新增量
计算配置更新增量：
curl -X POST -F original=@config.pb -F updated=@updated_config.pb http://127.0.0.1:7059/configtxlator/compute/update-from-configs -F channel=mychannel > config_update.pb
解码配置更新并将其包装到配置更新信封中
将配置更新文件解码为JSON：
curl -X POST --data-binary @config_update.pb http://127.0.0.1:7059/protolator/decode/common.ConfigUpdate > config_update.json
为配置更新消息创建一个信封：
echo '{"payload":{"header":{"channel_header":{"channel_id":"mychannel", "type":2}},"data":{"config_update":'$(cat config_update.json)'}}}' > config_update_as_envelope.json创建新的配置交易
将封装的消息编码为protobuf格式：
curl -X POST --data-binary @ config_update_as_envelope.json http://127.0.0.1:7059/protolator/encode/common.Envelope> config_update_as_envelope.pb
在cli容器上复制新交易：
docker cp config_update_as_envelope.pb cli:/opt/gopath/src/github.com/hyperledger/fabric/peer/
通过提交新签名的配置交易来更新频道
在所有MSP上签署配置更新交易：
将Org1MSP的签名添加到新交易中
docker exec -it \

现在添加Org3就完成了！
运行peer0.org3节点
为peer0.org3创建一个compose文件：
cat > docker-compose-peer0-org3.yaml <启动 peer0.org3:
docker-compose -f docker-compose-peer0-org3.yaml up -d
在peer2.org2上执行链码：
执行cli容器的shell：
docker exec -it cli bash
在shell上，运行以下命令：
CORE_PEER_TLS_ROOTCERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org3.example.com/peers/peer0.org3.example.com/tls/ca.crt
CORE_PEER_TLS_KEY_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org3.example.com/peers/peer0.org3.example.com/tls/server.key
