原文见 深入理解Fabric环境搭建的详细过程 http://www.cnblogs.com/studyzy/p/7451276.html 深蓝居
1、生成cryptogen（密码生成器）
我们将使用cryptogen工具为我们生成各种网络实体的加密材料（x509证书）。这些证书是身份的代表，它们允许在我们的网络实体进行交流和交易时进行签名/验证身份验证。
Fabric中有两种类型的公私钥和证书，一种是给节点之前通讯安全而准备的TLS证书，另一种是用户登录和权限控制的用户证书。这些证书本来应该是由CA来颁发，但是我们这里是测试环境，并没有启用CA节点，所以Fabric帮我们提供了一个工具：cryptogen。
cd /root/go/src/github.com/hyperledger/fabric
make cryptogen
结果如下：
build/bin/cryptogen CGO_CFLAGS=" " GOBIN=/root/go/src/github.com/hyperledger/fabric/build/bin go install -tags "" -ldflags "-X github.com/hyperledger/fabric/common/tools/cryptogen/metadata.Version=1.0.0" github.com/hyperledger/fabric/common/tools/cryptogen Binary available as build/bin/cryptogen
即 在./build/bin/cryptogen下生成了可执行程序cryptogen
2、配置网络拓扑 crypto-config.yaml
examples/e2e_cli/crypto-config.yaml已经提供了一个Orderer Org和两个Peer Org的配置，该模板中也对字段进行了注释。我们可以把Org2拿来分析一下：
- Name: Org2
Domain: org2.example.com
Template:
Count: 2
Users:
Count: 1
Name和Domain就是关于这个组织的名字和域名，这主要是用于生成证书的时候，证书内会包含该信息。而Template Count=2是说我们要生成2套公私钥和证书，一套是peer0.org2的，还有一套是peer1.org2的。最后Users. Count=1是说每个Template下面会有几个普通User（注意，Admin是Admin，不包含在这个计数中），这里配置了1，也就是说我们只需要一个普通用户[email protected] 我们可以根据实际需要调整这个配置文件，增删Org Users等。
3、使用加密生成器 cryptogen 根据网络拓扑 crypto-config.yaml生成相应证书
cd examples/e2e_cli/
../../build/bin/cryptogen generate --config=./crypto-config.yaml
生成的文件都保存到crypto-config

4、编译生成 交易生成器configtxgen
cd ~/go/src/github.com/hyperledger/fabric make configtxgen
运行后的结果为：
build/bin/configtxgen CGO_CFLAGS=" " GOBIN=/home/studyzy/go/src/github.com/hyperledger/fabric/build/bin go install -tags "nopkcs11" -ldflags "-X github.com/hyperledger/fabric/common/configtx/tool/configtxgen/metadata.Version=1.0.0" github.com/hyperledger/fabric/common/configtx/tool/configtxgen Binary available as build/bin/configtxgen
5、配置configtx.yaml
官方提供的examples/e2e_cli/configtx.yaml这个文件里面配置了由2个Org参与的Orderer共识配置TwoOrgsOrdererGenesis，以及由2个Org参与的Channel配置：TwoOrgsChannel。Orderer可以设置共识的算法是Solo还是Kafka，以及共识时区块大小，超时时间等，我们使用默认值即可，不用更改。而Peer节点的配置包含了MSP的配置，锚节点的配置。如果我们有更多的Org，或者有更多的Channel，那么就可以根据模板进行对应的修改。
6、通过交易生成器configtxgen生成区块
（1）生成创世区块
配置修改好后，我们就用configtxgen 生成创世区块。并把这个区块保存到本地channel-artifacts文件夹中：
cd examples/e2e_cli/ ../../build/bin/configtxgen -profile TwoOrgsOrdererGenesis -outputBlock ./channel-artifacts/genesis.block
（2）生成channel区块
../../build/bin/configtxgen -profile TwoOrgsChannel -outputCreateChannelTx ./channel-artifacts/channel.tx -channelID mychannel
另外关于锚节点的更新，我们也需要使用这个程序来生成文件：
../../build/bin/configtxgen -profile TwoOrgsChannel -outputAnchorPeersUpdate ./channel-artifacts/Org1MSPanchors.tx -channelID mychannel -asOrg Org1MSP ../../build/bin/configtxgen -profile TwoOrgsChannel -outputAnchorPeersUpdate ./channel-artifacts/Org2MSPanchors.tx -channelID mychannel -asOrg Org2MSP
最终，我们在channel-artifacts文件夹中，应该是能够看到4个文件。
root@ubuntu:~/go/src/github.com/hyperledger/fabric/examples/e2e_cli# tree channel-artifacts/ channel-artifacts/ ├── channel.tx ├── genesis.block ├── Org1MSPanchors.tx └── Org2MSPanchors.tx
7、配置Fabric环境的docker-compose文件
（1）配置Orderer
Orderer的配置是在base/docker-compose-base.yaml里
version: '2' services: orderer.example.com: container_name: orderer.example.com image: hyperledger/fabric-orderer environment: - ORDERER_GENERAL_LOGLEVEL=debug - ORDERER_GENERAL_LISTENADDRESS=0.0.0.0 - ORDERER_GENERAL_GENESISMETHOD=file - ORDERER_GENERAL_GENESISFILE=/var/hyperledger/orderer/orderer.genesis.block - ORDERER_GENERAL_LOCALMSPID=OrdererMSP - ORDERER_GENERAL_LOCALMSPDIR=/var/hyperledger/orderer/msp # enabled TLS - ORDERER_GENERAL_TLS_ENABLED=true - ORDERER_GENERAL_TLS_PRIVATEKEY=/var/hyperledger/orderer/tls/server.key - ORDERER_GENERAL_TLS_CERTIFICATE=/var/hyperledger/orderer/tls/server.crt - ORDERER_GENERAL_TLS_ROOTCAS=[/var/hyperledger/orderer/tls/ca.crt] working_dir: /opt/gopath/src/github.com/hyperledger/fabric command: orderer volumes: - ../channel-artifacts/genesis.block:/var/hyperledger/orderer/orderer.genesis.block - ../crypto-config/ordererOrganizations/example.com/orderers/orderer.example.com/msp:/var/hyperledger/orderer/msp - ../crypto-config/ordererOrganizations/example.com/orderers/orderer.example.com/tls/:/var/hyperledger/orderer/tls ports: - 7050:7050
这里主要关心的是，ORDERER_GENERAL_GENESISFILE=/var/hyperledger/orderer/orderer.genesis.block，而这个创世区块就是我们之前创建的创世区块，这里就是Host到Docker的映射：
- ../channel-artifacts/genesis.block:/var/hyperledger/orderer/orderer.genesis.block
另外的配置主要是TL，Log等，最后暴露出服务端口7050。、
（2）配置peer
Peer的配置是在base/docker-compose-base.yaml和peer-base.yaml里
docker-compose-base.yaml中截取peer0.org1.example.com配置
peer0.org1.example.com: container_name: peer0.org1.example.com extends: file: peer-base.yaml service: peer-base environment: - CORE_PEER_ID=peer0.org1.example.com - CORE_PEER_ADDRESS=peer0.org1.example.com:7051 - CORE_PEER_CHAINCODELISTENADDRESS=peer0.org1.example.com:7052 - CORE_PEER_GOSSIP_EXTERNALENDPOINT=peer0.org1.example.com:7051 - CORE_PEER_LOCALMSPID=Org1MSP volumes: - /var/run/:/host/var/run/ - ../crypto-config/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/msp:/etc/hyperledger/fabric/msp - ../crypto-config/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls:/etc/hyperledger/fabric/tls ports: - 7051:7051 - 7052:7052 - 7053:7053
peer-base.yaml
version: '2' services: peer-base: image: hyperledger/fabric-peer environment: - CORE_VM_ENDPOINT=unix:///host/var/run/docker.sock # the following setting starts chaincode containers on the same # bridge network as the peers # https://docs.docker.com/compose/networking/ - CORE_VM_DOCKER_HOSTCONFIG_NETWORKMODE=e2ecli_default #- CORE_LOGGING_LEVEL=ERROR - CORE_LOGGING_LEVEL=DEBUG - CORE_PEER_TLS_ENABLED=true - CORE_PEER_GOSSIP_USELEADERELECTION=true - CORE_PEER_GOSSIP_ORGLEADER=false - CORE_PEER_PROFILE_ENABLED=true - CORE_PEER_TLS_CERT_FILE=/etc/hyperledger/fabric/tls/server.crt - CORE_PEER_TLS_KEY_FILE=/etc/hyperledger/fabric/tls/server.key - CORE_PEER_TLS_ROOTCERT_FILE=/etc/hyperledger/fabric/tls/ca.crt working_dir: /opt/gopath/src/github.com/hyperledger/fabric/peer command: peer node start
（3）配置CLI
CLI在整个Fabric网络中扮演客户端的角色，我们在开发测试的时候可以用CLI来代替SDK，执行各种SDK能执行的操作。CLI会和Peer相连，把指令发送给对应的Peer执行。CLI的配置在docker-compose-cli.yaml中
# Copyright IBM Corp. All Rights Reserved. services: orderer.example.com: extends: file: base/docker-compose-base.yaml service: orderer.example.com container_name: orderer.example.com peer0.org1.example.com: container_name: peer0.org1.example.com extends: file: base/docker-compose-base.yaml service: peer0.org1.example.com peer1.org1.example.com: container_name: peer1.org1.example.com extends: file: base/docker-compose-base.yaml service: peer1.org1.example.com peer0.org2.example.com: container_name: peer0.org2.example.com extends: file: base/docker-compose-base.yaml service: peer0.org2.example.com peer1.org2.example.com: container_name: peer1.org2.example.com extends: file: base/docker-compose-base.yaml service: peer1.org2.example.com cli: container_name: cli image: hyperledger/fabric-tools tty: true environment: - GOPATH=/opt/gopath - CORE_VM_ENDPOINT=unix:///host/var/run/docker.sock - CORE_LOGGING_LEVEL=DEBUG - CORE_PEER_ID=cli - CORE_PEER_ADDRESS=peer0.org1.example.com:7051 - CORE_PEER_LOCALMSPID=Org1MSP - CORE_PEER_TLS_ENABLED=true - CORE_PEER_TLS_CERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/server.crt - CORE_PEER_TLS_KEY_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/server.key - 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/[email protected]/msp working_dir: /opt/gopath/src/github.com/hyperledger/fabric/peer command: /bin/bash -c './scripts/script.sh ${CHANNEL_NAME}; sleep $TIMEOUT' volumes: - /var/run/:/host/var/run/ - ../chaincode/go/:/opt/gopath/src/github.com/hyperledger/fabric/examples/chaincode/go - ./crypto-config:/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ - ./scripts:/opt/gopath/src/github.com/hyperledger/fabric/peer/scripts/ - ./channel-artifacts:/opt/gopath/src/github.com/hyperledger/fabric/peer/channel-artifacts depends_on: - orderer.example.com - peer0.org1.example.com - peer1.org1.example.com - peer0.org2.example.com - peer1.org2.example.com
从这里我们可以看到，CLI启动的时候默认连接的是peer0.org1.example.com，并且启用了TLS。默认是以[email protected]这个身份连接到Peer的。CLI启动的时候，会去执行./scripts/script.sh 脚本，这个脚本也就是fabric/examples/e2e_cli/scripts/script.sh 这个脚本，这个脚本完成了Fabric环境的初始化和ChainCode的安装及运行，也就是接下来要讲的步骤4和5.在文件映射配置上，我们注意到../chaincode/go/:/opt/gopath/src/github.com/hyperledger/fabric/examples/chaincode/go，也就是说我们要安装的ChainCode都是在fabric/examples/chaincode/go目录下，以后我们要开发自己的ChainCode，只需要把我们的代码复制到该目录即可。
8、初始化fabric环境
（1）启动Fabric环境的容器
我们将整个Fabric Docker环境的配置放在docker-compose-cli.yaml后，只需要使用以下命令即可：
docker-compose -f docker-compose-cli.yaml up -d
最后这个-d参数如果不加，那么当前终端就会一直附加在docker-compose上，而如果加上的话，那么docker容器就在后台运行。运行docker ps命令可以看启动的结果：1Orderer+4Peer+1CLI
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES e90ce174a429 hyperledger/fabric-tools "/bin/bash" 25 seconds ago Up 23 seconds cli 32ffc851c1bf hyperledger/fabric-peer "peer node start" 32 seconds ago Up 25 seconds 0.0.0.0:9051->7051/tcp, 0.0.0.0:9052->7052/tcp, 0.0.0.0:9053->7053/tcp peer0.org2.example.com 1f0d26e45634 hyperledger/fabric-peer "peer node start" 32 seconds ago Up 26 seconds 0.0.0.0:8051->7051/tcp, 0.0.0.0:8052->7052/tcp, 0.0.0.0:8053->7053/tcp peer1.org1.example.com 807c4dc97684 hyperledger/fabric-orderer "orderer" 32 seconds ago Up 24 seconds 0.0.0.0:7050->7050/tcp orderer.example.com c297c88cf9b3 hyperledger/fabric-peer "peer node start" 32 seconds ago Up 26 seconds 0.0.0.0:7051-7053->7051-7053/tcp peer0.org1.example.com 08c95a2bbb12 hyperledger/fabric-peer "peer node start" 32 seconds ago Up 25 seconds 0.0.0.0:10051->7051/tcp, 0.0.0.0:10052->7052/tcp, 0.0.0.0:10053->7053/tcp peer1.org2.example.com
（2）创建Channel
现在我们要进入cli容器内部，在里面创建Channel。先用以下命令进入CLI内部Bash：
docker exec -it cli bash
创建Channel的命令是peer channel create，我们前面创建2.4创建Channel的配置区块时，指定了Channel的名字是mychannel，那么这里我们必须创建同样名字的Channel。
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 mychannel -f ./channel-artifacts/channel.tx --tls true --cafile $ORDERER_CA
执行该命令后，系统会提示：
2017-08-29 20:36:47.486 UTC [channelCmd] readBlock -> DEBU 020 Received block:0
系统会在cli内部的当前目录创建一个mychannel.block文件，这个文件非常重要，接下来其他节点要加入这个Channel就必须使用这个文件。
（3）各个Peer加入Channel
前面说过，我们CLI默认连接的是peer0.org1，那么我们要将这个Peer加入mychannel就很简单，只需要运行如下命令：
peer channel join -b mychannel.block
系统返回消息：
2017-08-29 20:40:27.053 UTC [channelCmd] executeJoin -> INFO 006 Peer joined the channel!
那么其他几个Peer又该怎么加入Channel呢？这里就需要修改CLI的环境变量，使其指向另外的Peer。比如我们要把peer1.org1加入mychannel，那么命令是：
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/[email protected]/msp CORE_PEER_ADDRESS=peer1.org1.example.com:7051 peer channel join -b mychannel.block
系统会返回成功加入Channel的消息。
同样的方法，将peer0.org2加入mychannel：
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/[email protected]/msp CORE_PEER_ADDRESS=peer0.org2.example.com:7051 peer channel join -b mychannel.block
最后把peer1.org2加入mychannel：
CORE_PEER_LOCALMSPID="Org2MSP" CORE_PEER_TLS_ROOTCERT_FILE=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/peers/peer1.org2.example.com/tls/ca.crt CORE_PEER_MSPCONFIGPATH=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/users/[email protected]/msp CORE_PEER_ADDRESS=peer1.org2.example.com:7051 peer channel join -b mychannel.block
（4）更新锚节点
关于AnchorPeer，我理解的不够深刻，经过我的测试，即使没有设置锚节点的情况下，整个Fabric网络仍然是能正常运行的。
对于Org1来说，peer0.org1是锚节点，我们需要连接上它并更新锚节点：
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/[email protected]/msp CORE_PEER_ADDRESS=peer0.org1.example.com:7051 peer channel update -o orderer.example.com:7050 -c mychannel -f ./channel-artifacts/Org1MSPanchors.tx --tls true --cafile $ORDERER_CA
另外对于Org2，peer0.org2是锚节点，对应的更新代码是：
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/[email protected]/msp CORE_PEER_ADDRESS=peer0.org2.example.com:7051 peer channel update -o orderer.example.com:7050 -c mychannel -f ./channel-artifacts/Org2MSPanchors.tx --tls true --cafile $ORDERER_CA
以上，整个Fabric网络和Channel都准备完毕，接下来我们来安装和运行ChainCode。这里仍然以最出名的Example02为例。这个例子实现了a，b两个账户，相互之间可以转账。
9、链上代码的安装与运行
（1）Install ChainCode安装链上代码
链上代码的安装需要在各个相关的Peer上进行，对于我们现在这种Fabric网络，如果4个Peer都想对Example02进行操作，那么就需要安装4次。
仍然是保持在CLI的命令行下，我们先切换到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/[email protected]/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/hyperledger/fabric/examples/chaincode/go/chaincode_example02
安装的过程其实就是对CLI中指定的代码进行编译打包，并把打包好的文件发送到Peer，等待接下来的实例化。
其他节点由于暂时还没使用到，我们可以先不安装，等到了步骤5.4的时候再安装。
（2）Instantiate ChainCode实例化链上代码
实例化链上代码主要是在Peer所在的机器上对前面安装好的链上代码进行包装，生成对应Channel的Docker镜像和Docker容器。并且在实例化时我们可以指定背书策略。我们运行以下命令完成实例化：
peer chaincode instantiate -o orderer.example.com:7050 --tls true --cafile $ORDERER_CA -C mychannel -n mycc -v 1.0 -c '{"Args":["init","a","100","b","200"]}' -P "OR ('Org1MSP.member','Org2MSP.member')"
如果我们新开一个Ubuntu终端，去查看peer0.org1上的日志，那么就可以知道整个实例化的过程到底干了什么：
docker logs -f peer0.org1.example.com
主要几行重要的日志：
2017-08-29 21:14:12.290 UTC [chaincode-platform] generateDockerfile -> DEBU 3fd

接下来的日志就是各种初始化，验证，写账本之类的。总之完毕后，我们回到Ubuntu终端，使用docker ps可以看到有新的容器正在运行：
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES fc620b8c6399 dev-peer0.org1.example.com-mycc-1.0 "chaincode -peer.add…" 3 minutes ago Up 2 minutes dev-peer0.org1.example.com-mycc-1.0 e90ce174a429 hyperledger/fabric-tools "/bin/bash" 31 minutes ago Up 30 minutes cli 32ffc851c1bf hyperledger/fabric-peer "peer node start" 31 minutes ago Up 31 minutes 0.0.0.0:9051->7051/tcp, 0.0.0.0:9052->7052/tcp, 0.0.0.0:9053->7053/tcp peer0.org2.example.com 1f0d26e45634 hyperledger/fabric-peer "peer node start" 31 minutes ago Up 31 minutes 0.0.0.0:8051->7051/tcp, 0.0.0.0:8052->7052/tcp, 0.0.0.0:8053->7053/tcp peer1.org1.example.com 807c4dc97684 hyperledger/fabric-orderer "orderer" 31 minutes ago Up 31 minutes 0.0.0.0:7050->7050/tcp orderer.example.com c297c88cf9b3 hyperledger/fabric-peer "peer node start" 31 minutes ago Up 31 minutes 0.0.0.0:7051-7053->7051-7053/tcp peer0.org1.example.com 08c95a2bbb12 hyperledger/fabric-peer "peer node start" 31 minutes ago Up 31 minutes 0.0.0.0:10051->7051/tcp, 0.0.0.0:10052->7052/tcp, 0.0.0.0:10053->7053/tcp peer1.org2.example.com
（3）在一个Peer上查询并发起交易
现在链上代码的实例也有了，并且在实例化的时候指定了a账户100，b账户200，我们可以试着调用ChainCode的查询代码，验证一下，在cli容器内执行：
peer chaincode query -C mychannel -n mycc -c '{"Args":["query","a"]}'
返回结果：Query Result: 100
接下来我们可以试着把a账户的10元转给b。对应的代码：
peer chaincode invoke -o orderer.example.com:7050 --tls true --cafile $ORDERER_CA -C mychannel -n mycc -c '{"Args":["invoke","a","b","10"]}'
（4）在另一个节点上查询交易
前面的操作都是在org1下面做的，那么处于同一个区块链（同一个Channel下）的org2，是否会看org1的更改呢？我们试着给peer0.org2安装链上代码：
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/[email protected]/msp CORE_PEER_ADDRESS=peer0.org2.example.com:7051 peer chaincode install -n mycc -v 1.0 -p github.com/hyperledger/fabric/examples/chaincode/go/chaincode_example02
由于mycc已经在前面org1的时候实例化了，也就是说对应的区块已经生成了，所以在org2不能再次初始化。我们直接运行查询命令：
peer chaincode query -C mychannel -n mycc -c '{"Args":["query","a"]}'
返回结果：
Query Result: 90
这是因为peer0.org2也需要生成Docker镜像，创建对应的容器，才能通过容器返回结果。我们回到Ubuntu终端，执行docker ps，可以看到又多了一个容器：
