一、基础环境准备
1、 安装docker
安装docker依赖库：
yum install -y yum-utils device-mapper-persistent-data lvm2
添加Docker CE的软件源信息：
yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
dnf makecache
安装最新版docker：
yum -y install docker-ce
systemctl start docker
查看是否安装成功：
docker version
注意：在 安装时可能会出现模块依赖问题，
解决方案：
-
下载docker-ce的repo
curl https://download.docker.com/linux/centos/docker-ce.repo -o /etc/yum.repos.d/docker-ce.repo -
安装依赖
wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo yum install https://download.docker.com/linux/fedora/30/x86_64/stable/Packages/containerd.io-1.2.6-3.3.fc30.x86_64.rpm -
安装docker-ce
yum install docker-ce
即可解决。
查看docker版本：
[lj@localhost yum.repos.d]$ sudo docker version

3、 安装golang
下载文件:
wget -P /usr/local https://dl.google.com/go/go1.16.linux-amd64.tar.gz
解压文件到 /usr/local（可以自行选择路径）
cd /usr/local
tar -zxvf go1.16.linux-amd64.tar.gz
配置环境
vim /etc/profile
写入
export PATH=$PATH:/usr/local/go/bin
export GOROOT=/usr/local/go
export GOPATH=/root/go/
#根据自己的路径进行修改
使环境配置生效
source /etc/profile
查看版本
go version
结果
[root@localhost ~]# vim /etc/profile
[root@localhost ~]# source /etc/profile
[root@localhost ~]# go version
go version go1.16 linux/amd64
4、 安装Node
wget https://npm.taobao.org/mirrors/node/v14.4.0/node-v14.4.0-linux-x64.tar.xz
tar -xvf node-v14.4.0-linux-x64.tar.xz

5、 安装 Git
yum install git
查看版本
git version
二、fabric 源码安装
1、下载源码
git clone https://github.com/hyperledger/fabric.git
cd fabric/scripts
#下载镜像和二进制文件：
sudo ./bootstrap.sh
过程会比较慢，有可能出现卡顿的情况，多试几次。
2、使用测试网络
跑之前先清一下docker网络环境
docker stop $(docker ps -aq)
docker rm $(docker ps -qa)
启动test-network测试网络：
cd /home/lj/fabric/scripts/fabric-samples/test-network #(改成自己的安装目录)
./network.sh up
结果如下
[root@localhost test-network]# ./network.sh up
Using docker and docker-compose
Starting nodes with CLI timeout of '5' tries and CLI delay of '3' seconds and using database 'leveldb'

也可以带上channel标签，命令如下（-c channelName）：
./network.sh createChannel -c channel1
如果要在一个步骤中启动网络并创建频道，可以同时使用up和create channel模式：
./network.sh up createChannel

go list 发生失败，这时通过 go env 可以看到，go 的代理默认是：https://proxy.golang.org,direct.
将代理更改为：goproxy.cn,direct。
执行：
go env -w GOPROXY=https://goproxy.cn,direct
再次执行 go env 可以看到代理已经更换了。
好，再去执行：
./network.sh deployCC -ccn basic -ccp ../asset-transfer-basic/chaincode-go -ccl go
执行结果

代表链码部署成功。
可以指定语言，加-l ，比如用java，命令如下：
./network.sh deployCC -l java
关闭网络：
./network.sh down
三、chaincode部署（以go为例）
使用Peer CLI来向通道中部署链代码：
-
第一步，打包链码
-
第二步，安装打包的链码
-
第三步，各组织对链码内容和定义达成一致
-
第四步，向channel中提交链码
在进行如下步骤之前，首先需要关闭网络，然后再重启网络，同时创建channel，即如下两条命令。
./network.sh down
./network.sh up createChannel
1、打包链码
1.1、安装依赖
cd fabric/scripts/fabric-samples/chaincode/fabcar/go
GO111MODULE=on go mod vendor
1.2、使用peer CLI打包链码，
peer的可执行二级制文件在fabric-sample的bin文件夹中。使用如下命令添加Peer到CLI命令路径中
cd ../../../test-network
export PATH=${PWD}/../bin:$PATH
还需要设置指向fabric-samples中core.yaml的FABRIC_CFG_PATH
export FABRIC_CFG_PATH=$PWD/../config/
查看peer版本来确认是否安装成功
peer version
[root@localhost lj]# cd fabric
[root@localhost fabric]# cd scripts
[root@localhost scripts]# cd fabric-samples/chaincode/fabcar/go
[root@localhost go]# GO111MODULE=on go mod vendor
[root@localhost go]# cd ../../../test-network
[root@localhost test-network]# export PATH=${PWD}/../bin:$PATH
[root@localhost test-network]# export FABRIC_CFG_PATH=$PWD/../config/
[root@localhost test-network]# peer version
peer:
Version: 2.3.0
Commit SHA: ec81f3e74
Go version: go1.14.12
OS/Arch: linux/amd64
Chaincode:
Base Docker Label: org.hyperledger.fabric
Docker Namespace: hyperledger
打包链代码
peer lifecycle chaincode package fabcar.tar.gz --path ../chaincode/fabcar/go/ --lang golang --label fabcar_1
此命令会在当前目录下创建fabcar.tar.gz文件，–lang标识链码的编程语言，–path链码路径，–label链码安装后的标签,建议包含链码名称和版本。
2、安装打包的链码
由于有两个peer链码需要再所有参与背书的peer上安装。因为我们将要设置的背书策略是，Org1和Org2同时背书，所以Org1和Org2上都要安装链码。
首先在Org1的peer上安装，通过设置环境变量来指定peer操作的是Org1
export CORE_PEER_TLS_ENABLED=true
export CORE_PEER_LOCALMSPID="Org1MSP"
export CORE_PEER_TLS_ROOTCERT_FILE=${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt
export CORE_PEER_MSPCONFIGPATH=${PWD}/organizations/peerOrganizations/org1.example.com/users/[email protected]/msp
export CORE_PEER_ADDRESS=localhost:7051
在peer上安装链码
peer lifecycle chaincode install fabcar.tar.gz
[lj@localhost test-network]$ peer lifecycle chaincode install fabcar.tar.gz
2022-06-03 02:13:35.452 CST [cli.lifecycle.chaincode] submitInstallProposal -> INFO 001 Installed remotely: response:<status:200 payload:"\nIfabcar_1:1146b4b491871bf18b23dd67dd8cc058655b36cc0e2274f165ed06b796a8f276\022\010fabcar_1" >

下面安装Org2的peer
export CORE_PEER_LOCALMSPID="Org2MSP"
export CORE_PEER_TLS_ROOTCERT_FILE=${PWD}/organizations/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt
export CORE_PEER_TLS_ROOTCERT_FILE=${PWD}/organizations/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt
export CORE_PEER_MSPCONFIGPATH=${PWD}/organizations/peerOrganizations/org2.example.com/users/[email protected]/msp
export CORE_PEER_ADDRESS=localhost:9051
peer lifecycle chaincode install fabcar.tar.gz
[lj@localhost test-network]$ peer lifecycle chaincode install fabcar.tar.gz
2022-06-03 02:16:45.300 CST [cli.lifecycle.chaincode] submitInstallProposal -> INFO 001 Installed remotely: response:<status:200 payload:"\nIfabcar_1:1146b4b491871bf18b23dd67dd8cc058655b36cc0e2274f165ed06b796a8f276\022\010fabcar_1" >
2022-06-03 02:16:45.307 CST [cli.lifecycle.chaincode] submitInstallProposal -> INFO 002 Chaincode code package identifier: fabcar_1:1146b4b491871bf18b23dd67dd8cc058655b36cc0e2274f165ed06b796a8f276
3、审议链码定义
安装链码包后，需要组织审议链码的定义。定义包含管理链码的参数如名称、版本，背书策略.
channel内的成员需要在部署链码之前对链码的定义达成一致。使用Application/Channel/lifeycleEndorsement。默认需要大多数成员对链码定义达成一致。这里我们有两个组织Org1和Org2，多数的情况是，两个组织都要达成一致。
如果一个组织内的peer已经安装了链码，那么组织在审议链码定义时需要包含packageID。packageID用于关联peer上安装的链码和审议过的链码定义，且用于组织为交易做背书。
可以用下面命令查找peer上的package ID
peer lifecycle chaincode queryinstalled
[lj@localhost test-network]$ peer lifecycle chaincode queryinstalled
Installed chaincodes on peer:
Package ID: fabcar_1:1146b4b491871bf18b23dd67dd8cc058655b36cc0e2274f165ed06b796a8f276, Label: fabcar_1
package ID是链码标签和链码二级制hash值的结合，每个peer会产生相同的packageID。
在审议链码时会用到packageID，所以我们先把它保存到一个环境变量中，执行下面命令（值为上一步得到的输出）
export CC_PACKAGE_ID=fabcar_1:1146b4b491871bf18b23dd67dd8cc058655b36cc0e2274f165ed06b796a8f276
因为当前设置的是Org2的环境变量，我们可以用Org2来审议链码。审议是组织级别的，所以只需要一个peer节点操作，审议结果会通过gossip协议通知到组织内。审议链码执行以下命令：
peer lifecycle chaincode approveformyorg -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --channelID mychannel --name fabcar --version 1.0 --package-id $CC_PACKAGE_ID --sequence 1 --tls true --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem
[lj@localhost test-network]$ peer lifecycle chaincode approveformyorg -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --channelID mychannel --name fabcar --version 1.0 --package-id $CC_PACKAGE_ID --sequence 1 --tls true --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem
2022-06-03 02:30:09.030 CST [chaincodeCmd] ClientWait -> INFO 001 txid [5e96f08ad85e711cfa703b0cd3b2bead73308ebeccfb550687a8dc1ed6847c60] committed with status (VALID) at localhost:9051
通过–package-id来标识链码，–sequence是一个整数用来追踪链码定义和升级次数。因为此处是第一次部署链码到channel中，所以sequence是1，当此链码升级的时候，sequence要递增到2。如果你使用的是低版本的链码API，可以使用–init-required来执行链码的初始化init。第一次invoke调用链码时需要使用–isInit来初始化链码，执行init函数。
我们可以对approveformyorg 命令使用–signature-policy 或–channel-config-policy参数来指定链码的背书策略。背书策略指定需要多个组织内的peer来为交易做背书。此处我们没有指定背书策略，链码会使用默认的背书策略（运行的peer中大多数为交易做背书）。预示着如果新组织加入或删除组织，背书策略会自动升级为需要更多或更少的背书。本文档中，默认策略是需要来自Org1和Org2的2个peer。如果要自定义背书策略，查看官方文档。
需要用admin的身份来审议链码定义，因此CORE_PEER_MSPCONFIGPATH 要执行admin的账户。客户端用户不能审议链码，审议结果会提交给排序服务器，排序服务器验证管理员签名后会将审议结果分发给组织内的peers。
同样Org1也需要进行相同的操作
export CORE_PEER_LOCALMSPID="Org1MSP"
export CORE_PEER_MSPCONFIGPATH=${PWD}/organizations/peerOrganizations/org1.example.com/users/[email protected]/msp
export CORE_PEER_TLS_ROOTCERT_FILE=${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt
export CORE_PEER_ADDRESS=localhost:7051
peer lifecycle chaincode approveformyorg -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --channelID mychannel --name fabcar --version 1.0 --package-id $CC_PACKAGE_ID --sequence 1 --tls true --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem
[lj@localhost test-network]$ export CORE_PEER_LOCALMSPID="Org1MSP"
[lj@localhost test-network]$
[lj@localhost test-network]$ export CORE_PEER_MSPCONFIGPATH=${PWD}/organizations/peerOrganizations/org1.example.com/users/[email protected]/msp
[lj@localhost test-network]$
[lj@localhost test-network]$ export CORE_PEER_TLS_ROOTCERT_FILE=${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt
[lj@localhost test-network]$
[lj@localhost test-network]$ export CORE_PEER_ADDRESS=localhost:7051
[lj@localhost test-network]$
[lj@localhost test-network]$ peer lifecycle chaincode approveformyorg -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --channelID mychannel --name fabcar --version 1.0 --package-id $CC_PACKAGE_ID --sequence 1 --tls true --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem
2022-06-03 02:30:55.745 CST [chaincodeCmd] ClientWait -> INFO 001 txid [6535be744fdd71f89122c5977807e94d299703697865a8fe8724aab819501523] committed with status (VALID) at localhost:7051
我们现在有了大多数成员的同意可以在channel上部署链码了。虽然只需要大多数组织来审议链码定义，但只有审议通过链码的组织，才能安装链码。在某个组织审议链码之前提交的链码定义，此组织不可为交易做背书。因此推荐在所有组织审议链码之后再提交链码定义。
4、向Channel中提交链码定义
在足够数量的组织为链码定义达成一致后，一个组织可以提交链码定义到Channel中。如果大多数组织同意了链码定义，提交事务会成功执行，且链码定义的参数会在channel中生效。
可以使用如下命令来查看哪些成员已经同意了链码定义。
peer lifecycle chaincode checkcommitreadiness --channelID mychannel --name fabcar --version 1.0 --sequence 1 --tls true --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem --output json
2022-06-03 02:30:55.745 CST [chaincodeCmd] ClientWait -> INFO 001 txid [6535be744fdd71f89122c5977807e94d299703697865a8fe8724aab819501523] committed with status (VALID) at localhost:7051
[lj@localhost test-network]$ peer lifecycle chaincode checkcommitreadiness --channelID mychannel --name fabcar --version 1.0 --sequence 1 --tls true --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem --output json
{
"approvals": {
"Org1MSP": true,
"Org2MSP": true
}
}
命令会以json的形式显示输出，组织是否已经同意了checkcommitreadiness命令中指定的参数。
通道内所有组织都同意了链码定义之后，链码定义就可以提交到channel中，执行以下命令提交提交channel中
peer lifecycle chaincode commit -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --channelID mychannel --name fabcar --version 1.0 --sequence 1 --tls true --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem --peerAddresses localhost:7051 --tlsRootCertFiles ${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt --peerAddresses localhost:9051 --tlsRootCertFiles ${PWD}/organizations/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt
[lj@localhost test-network]$ peer lifecycle chaincode commit -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --channelID mychannel --name fabcar --version 1.0 --sequence 1 --tls true --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem --peerAddresses localhost:7051 --tlsRootCertFiles ${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt --peerAddresses localhost:9051 --tlsRootCertFiles ${PWD}/organizations/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt
2022-06-03 02:32:04.393 CST [chaincodeCmd] ClientWait -> INFO 001 txid [5ffcf0867756ac022ccbef8ee190a43763224f1b52eea33e37c5ccff24a20e90] committed with status (VALID) at localhost:9051
2022-06-03 02:32:04.495 CST [chaincodeCmd] ClientWait -> INFO 002 txid [5ffcf0867756ac022ccbef8ee190a43763224f1b52eea33e37c5ccff24a20e90] committed with status (VALID) at localhost:7051
上述命令使用了–peerAddresses来指定Org1和Org2中的两个节点，提交事务提交给了加入通道peers，可以用来查询链码定义。
这个命令需要有满足部署链码策略的数量peers，因为同意链码定义已经同步到组织内部，所以可以选择组织内任意一个peer。
通道内成员背书的链码定义会提交到排序服务节点上，然后在通道中会创建一个区块。通道上的peers会验证是否有足够的组织同意了链码定义，peer lifecycle chaincode commit会一直等待peers的验证结果。
可以使用如下命令来确认链码定义是否已经被提交到通道上。
peer lifecycle chaincode querycommitted --channelID mychannel --name fabcar --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem
[lj@localhost test-network]$ peer lifecycle chaincode querycommitted --channelID mychannel --name fabcar --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem
Committed chaincode definition for chaincode 'fabcar' on channel 'mychannel':
Version: 1.0, Sequence: 1, Endorsement Plugin: escc, Validation Plugin: vscc, Approvals: [Org1MSP: true, Org2MSP: true]
5、调用链码
如果链码定义提交成功，链码会在安装的peer上开始运行。链码已经可以被客户端调用。使用下面的命令初始化创建一组cars数据。注意链码调用需要有满足策略的足够的背书节点。
peer chaincode invoke -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --tls true --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C mychannel -n fabcar --peerAddresses localhost:7051 --tlsRootCertFiles ${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt --peerAddresses localhost:9051 --tlsRootCertFiles ${PWD}/organizations/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt -c '{"function":"initLedger","Args":[]}'
可以使用query函数来查询数据
peer chaincode query -C mychannel -n fabcar -c '{"Args":["queryAllCars"]}'
6、升级链码
可以使用lifecycle 来升级已经部署的链码。通道中成员可以升级链码：安装新链码包，审议链码定义，新的链码版本，新的sequence（递增一位）。新的链码在提交到channel后可以调用。lifecycle进程使通道内的成员在链码升级时协调一致，并确保在部署新链码之前有足够数量的通道成员已经准备使用新链码。
通道内成员也可以使用升级程序来升级链码的背书策略。通过审议新背书策略的链码定义并提交链码定义到通道中，通道成员可以成员可以更改背书策略而不用安装新的链码。
假设链码升级的场景是，Org1和Org2想安装一般用另一种语言写的链码。使用lifecycle升级链码，并确保每个组织都安装上了新的链码后才激活新链码。
我们一开始在Org1和Org2上安装的是GO语言的版本链码，但为了更合适的开发需要JS写的链码。第一步是打包JS版本的链码。如果你一开始使用的是JS版本链码，这里你可以使用Go或者Java版。
执行test-network目录下如下命令，来安装依赖包
cd ../chaincode/fabcar/javascript
npm install
cd ../../../test-network
[lj@localhost test-network]$ cd ../chaincode/fabcar/javascript
[lj@localhost javascript]$ npm install

执行test-network目录下如下命令来打包链码。并且设置peer CLI的环境变量，以防已经关闭了CLI终端。
export PATH=${PWD}/../bin:$PATH
export FABRIC_CFG_PATH=$PWD/../config/
export CORE_PEER_MSPCONFIGPATH=${PWD}/organizations/peerOrganizations/org1.example.com/users/[email protected]/msp
peer lifecycle chaincode package fabcar_2.tar.gz --path ../chaincode/fabcar/javascript/ --lang node --label fabcar_2
设置环境变量使用Org1 Admin身份运行peer CLI
export CORE_PEER_TLS_ENABLED=true
export CORE_PEER_LOCALMSPID="Org1MSP"
export CORE_PEER_TLS_ROOTCERT_FILE=${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt
export CORE_PEER_MSPCONFIGPATH=${PWD}/organizations/peerOrganizations/org1.example.com/users/[email protected]/msp
export CORE_PEER_ADDRESS=localhost:7051
接下来在Org1的peer上安装新的链码
peer lifecycle chaincode install fabcar_2.tar.gz
新安装的链码会有新的packageID，使用如下命令查询pacage ID
peer lifecycle chaincode queryinstalled
[lj@localhost test-network]$ peer lifecycle chaincode queryinstalled
Installed chaincodes on peer:
Package ID: fabcar_1:1146b4b491871bf18b23dd67dd8cc058655b36cc0e2274f165ed06b796a8f276, Label: fabcar_1
Package ID: fabcar_2:42f98fe23534452f034acd1f9ccea876a3dbf92819bf19d0469aa891535a9d81, Label: fabcar_2
保存新的packageID到环境变量
export NEW_CC_PACKAGE_ID=fabcar_2:42f98fe23534452f034acd1f9ccea876a3dbf92819bf19d0469aa891535a9d81
接下来Org1投票链码的定义。
peer lifecycle chaincode approveformyorg -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --channelID mychannel --name fabcar --version 2.0 --package-id $NEW_CC_PACKAGE_ID --sequence 2 --tls --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem
新的链码定义使用JS版链码的packageID并且升级了链码的版本。因为sequence参数是用来追踪量升级的，所以Org1需要将值从1变到2。如果忘记上个版本的sequence值，可以使用peer lifecycle chaincode querycommitted查询。
现在操作Org2
export CORE_PEER_LOCALMSPID="Org2MSP"
export CORE_PEER_TLS_ROOTCERT_FILE=${PWD}/organizations/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt
export CORE_PEER_MSPCONFIGPATH=${PWD}/organizations/peerOrganizations/org2.example.com/users/[email protected]/msp
export CORE_PEER_ADDRESS=localhost:9051
peer lifecycle chaincode install fabcar_2.tar.gz
peer lifecycle chaincode approveformyorg -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --channelID mychannel --name fabcar --version 2.0 --package-id $NEW_CC_PACKAGE_ID --sequence 2 --tls --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem
查询是否达成一致，可以提交到channel中了
peer lifecycle chaincode checkcommitreadiness --channelID mychannel --name fabcar --version 2.0 --sequence 2 --tls --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem --output json
当新的链码定义通过之后，就可以在channel中升级链码了。直到现在，之前版本的链码还在各组织上运行。Org2使用如下命令执行channel中链码升级。
peer lifecycle chaincode commit -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --channelID mychannel --name fabcar --version 2.0 --sequence 2 --tls --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem --peerAddresses localhost:7051 --tlsRootCertFiles ${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt --peerAddresses localhost:9051 --tlsRootCertFiles ${PWD}/organizations/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt
一个新的交易提交到Fabric后会立即使用新版链码。如果过新的链码定义改变了背书策略，新的策略也会立即生效。
可以使用docker ps命令来验证新的链码已经在peer上启动
docker ps
[lj@localhost test-network]$ docker ps

如果使用了–init-required参数，你需要首先调用Init函数。这里因为不用执行Init，我们可以直接测试新链码。
peer chaincode invoke -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --tls --cafile ${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C mychannel -n fabcar --peerAddresses localhost:7051 --tlsRootCertFiles ${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt --peerAddresses localhost:9051 --tlsRootCertFiles ${PWD}/organizations/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt -c '{"function":"createCar","Args":["CAR11","Honda","Accord","Black","Tom"]}'

可以再查一下数据，看有没有新数据。
peer chaincode query -C mychannel -n fabcar -c '{"Args":["queryAllCars"]}'
复原环境
当调用完毕链码，你可以使用下面的命令来删除Logspout tool。
docker stop logspout
docker rm logspout
#停止测试网络
./network.sh down
四、使用SDK与fabric网络交互
跑之前先清一下docker网络环境
docker stop $(docker ps -aq)
docker rm $(docker ps -qa)
启动fabric
