Hyperledger fabric 2.2.1 环境搭建
    	https://www.cnblogs.com/Earth-SmaThing/p/13570540.html
    	最好使用root身份用户，否则很多权限被禁止(例如docker-compose命令找不到)
    	基础环境搭建-----------------------------------------------------
    		### docker 安装 (可参考https://my.oschina.net/ruoli/blog/1592170)
    		如果服务器上有旧版的docker，需要先执行卸载操作。
    		$ sudo yum remove docker \ 
    									   docker-common \ 
    									   docker-selinux \ 
    									   docker-engine
    								   
    	随后开始安装docker-ce
    		$ sudo yum install -y yum-utils device-mapper-persistent-data lvm2
    
    		$ sudo yum-config-manager \
    		  --add-repo \
    		https://download.docker.com/linux/centos/docker-ce.repo
    		或
    		鉴于国内网络问题，强烈建议使用国内源，如下：
    		$ sudo yum-config-manager \
    		    --add-repo \
    		    https://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
    
    		$ sudo yum-config-manager --enable docker-ce-edge
    
    		$ sudo yum-config-manager --enable docker-ce-test
    
    		$ sudo yum-config-manager --disable docker-ce-edge
    
    		$ sudo yum makecache fast
    
    		$ sudo yum install docker-ce
    
    	执行查询docker版本号，看是否安装成功
    	docker --version
    
    	docker启动
    	service docker start
    
    	docker开机自启（视具体情况使用）
    	chkconfig docker on
    
    	### docker-compose 安装
    	需要服务器支持 curl 功能，如果服务器不支持 curl 功能，需要手动进行安装
    	yum install curl
    
    	执行如下操作下载docker-compose
    	sudo curl -L "https://github.com/docker/compose/releases/download/1.26.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
    
    	下载目录为：
    	/usr/local/bin/docker-compose
    
    	为其添加可执行权限：
    	sudo chmod +x /usr/local/bin/docker-compose
    
    	查询版本信息：
    	docker-compose --version
    
    	### Go语言安装
    	安装包下载
    	curl -O https://golang.google.cn/doc/install?download=go1.15.linux-amd64.tar.gz
    
    	解压缩文件包
    	tar -C /usr/local -xzf go1.15.linux-amd64.tar.gz
    
    	配置 go 的环境变量
    		修改 /etc/profile 文件使其永久生效
    		1 export PATH=$PATH:/usr/local/go/bin
    		2 export GOPATH=/opt/gopath
    
    		修改文件后，执行如下命令，应用上述参数
    		source /etc/profile
    		
    	查看当前 go 版本信息
    	go version
    
    	也可通过下述命令查看是否安装成功
    	echo $PATH
    Fabric源码及镜像文件处理-------------------------------------------
    	下载 fabric 源码是因为要用到源码中的例子和工具，工具编译需要用到 go 语言环境，因此需要把源码目录放到 GOPATH 下，路径设置为 /opt/gopath
    	可以使用 Git 命令下载源码（耗时会比较长）：
    	cd /opt/gopath/src/github.com/hyperledger/
    	git clone https://github.com/hyperledger/fabric.git
    
    	如果没有 git 命令，需要先执行如下命令，构建 git 环境：
    	yum install git
    
    	默认Fabric源码下载版本为 2.2.0
    
    	Fabric Docker 镜像的下载：
    	cd /opt/gopath/src/github.com/hyperledger/fabric/scripts
    	./bootstrap.sh
    	等待下载完成即可
    
    	至此，Fabric源码，fabric-samples 源码、fabric 镜像的工作已经完成
    网络环境测试---------------------------------------------------------
    	启动 Fabric 网络  必须root身份 否则network.sh文件里面的docker-compse命令无法找到
    	cd /opt/gopath/src/github.com/hyperledger/fabric/scripts/fabric-samples/test-network
    	./network.sh up
    
    	建立通道
    	./network.sh createChannel
    
    	在通道上启动链码
    	./network.sh deployCC
    
    	如果链码启动失败，手动添加 go 代理
    	go env -w GO111MODULE=on
    	go env -w GOPROXY=https://goproxy.cn,direct
    	再次启动链码即可
    
    	在test-network 目录进行如下环境变量设置
    	export PATH=${PWD}/../bin:${PWD}:$PATH
    	export FABRIC_CFG_PATH=$PWD/../config/
    
    	继续设置如下环境变量，允许以 peer Org1 的形式操作 CLI
    	# Environment variables for 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/Admin@org1.example.com/msp
    	export CORE_PEER_ADDRESS=localhost:7051
    
    	完成后，source /etc/profile
    
    	获取已添加到通道分类账中的汽车列表
    	peer chaincode query -C mychannel -n fabcar -c '{"Args":["queryAllCars"]}'
    	上述命令可能会出现报错提示，如下（如果是提示某些文件不存在，我的一个解决办法是，关闭网络，启动网络前，source /etc/profile）：
    	Error: endorsement failure during query. response: status:500 message:"make sure the chaincode fabcar has been successfully defined on channel mychannel and try again: chaincode fabcar not found"
    	查看报错信息，我们可以知道，链码 fabcar 没有在通道上被定义，所以我们进入对应目录，执行启动指令：
    	cd /opt/gopath/src/github.com/hyperledger/fabric/scripts/fabric-samples/fabcar
    	./startFabric.sh
    	等待执行结束即可 切记执行命令如果还报错如下
    		报错:
    			Error: failed to create deliver client for orderer: orderer client failed to connect to orderer.example.com:7050: failed to create new connection: connection error: desc = “transport: error while dialing: dial tcp 192.168.1.20:7050: connect: no route to host”
    		那么需要进行关闭防火墙操作然后再次执行./startFabric.sh(注意语言环境)
    			systemctl status firewalld.service          #查看防火墙状态
    			systemctl stop firewalld.service            #停止firewall
    			systemctl disable firewalld.service         #禁止firewall开机启动
    
    	我们现在可以重新进入 test-network 目录，执行命令
    	peer chaincode query -C mychannel -n fabcar -c '{"Args":["queryAllCars"]}'
    	可以看到，正常返回结果了
    	[{"Key":"CAR0","Record":{"make":"Toyota","model":"Prius","colour":"blue","owner":"Tomoko"}},{"Key":"CAR1","Record":{"make":"Ford","model":"Mustang","colour":"red","owner":"Brad"}},{"Key":"CAR2","Record":{"make":"Hyundai","model":"Tucson","colour":"green","owner":"Jin Soo"}},{"Key":"CAR3","Record":{"make":"Volkswagen","model":"Passat","colour":"yellow","owner":"Max"}},{"Key":"CAR4","Record":{"make":"Tesla","model":"S","colour":"black","owner":"Adriana"}},{"Key":"CAR5","Record":{"make":"Peugeot","model":"205","colour":"purple","owner":"Michel"}},{"Key":"CAR6","Record":{"make":"Chery","model":"S22L","colour":"white","owner":"Aarav"}},{"Key":"CAR7","Record":{"make":"Fiat","model":"Punto","colour":"violet","owner":"Pari"}},{"Key":"CAR8","Record":{"make":"Tata","model":"Nano","colour":"indigo","owner":"Valeria"}},{"Key":"CAR9","Record":{"make":"Holden","model":"Barina","colour":"brown","owner":"Shotaro"}}]
    	
    	上述调试工作相继完成后，我们继续如下操作（仍然在 test-network 目录下），执行关闭网络指令：
    	./network.sh down
    	接着，编辑profile文件，添加如下内容（因为资产转移链码的背书策略要求事务由 Org1 和 Org2 签名，chaincode invoke 命令需要同时针对 peer0.org1.example.com 和 peer0.org2.example.com 使用 --peeradresses 标志，而且，由于为网络启用了 TLS， 该命令还需要使用 --tlsRootCertFiles 标志为每个对等方引用 TLS 证书。）：
    	# Environment variables for Org2 注意${PWD}路径所指 所以还是在当前test-network目录下执行如下
    
    		export CORE_PEER_TLS_ENABLED=true
    		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/Admin@org2.example.com/msp
    		export CORE_PEER_ADDRESS=localhost:9051
    		保存退出
    
    		source /etc/profile
    		
    	启动测试网络：
    	./network.sh up
    	./network.sh createChannel
    	./network.sh deployCC
    	运行如下命令初始化资产分类账：
    		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 basic --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":[]}'
    	如果有如下报错信息，可能是链码没有在通道中被成功定义，关闭测试网络后，重新执行启动网络操作：
    		Error: endorsement failure during invoke. response: status:500 message:"make sure the chaincode basic has been successfully defined on channel mychannel and try again: chaincode basic not found"
    	上述初始化指令的执行成功返回结果信息如下：
    		2020-08-28 11:20:52.062 CST [chaincodeCmd] chaincodeInvokeOrQuery -> INFO 001 Chaincode invoke successful. result: status:200
    	运行以下命令获取添加到通道分类账的资产列表：
    		peer chaincode query -C mychannel -n basic -c '{"Args":["GetAllAssets"]}'
    	返回结果如下：
    		[{"ID":"asset1","color":"blue","size":5,"owner":"Tomoko","appraisedValue":300},{"ID":"asset2","color":"red","size":5,"owner":"Brad","appraisedValue":400},{"ID":"asset3","color":"green","size":10,"owner":"Jin Soo","appraisedValue":500},{"ID":"asset4","color":"yellow","size":10,"owner":"Max","appraisedValue":600},{"ID":"asset5","color":"black","size":15,"owner":"Adriana","appraisedValue":700},{"ID":"asset6","color":"white","size":15,"owner":"Michel","appraisedValue":800}]
    	当网络成员希望转移或更改分类账上的资产时，会调用链码。使用以下命令更改分类账上的资产所有者：
    		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 basic --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":"TransferAsset","Args":["asset6","Christopher"]}'
    	返回如下提示信息，即表示更改成功：
    		2020-08-28 11:21:29.252 CST [chaincodeCmd] chaincodeInvokeOrQuery -> INFO 001 Chaincode invoke successful. result: status:200
    	使用如下命令查询刚刚的转移信息：
    		peer chaincode query -C mychannel -n basic -c '{"Args":["ReadAsset","asset6"]}'
    	返回结果如下：
    		{"ID":"asset6","color":"white","size":15,"owner":"Christopher","appraisedValue":800}
    	
    启动过程问题	
    		Error: got unexpected status: BAD_REQUEST -- error authorizing update: error validating ReadSet: readset expected key [Group]  /Channel/Application at version 0, but got version 1
    		此问题是历史数据未清除干净，可能造成的原因：由于在本机尝试过fabric的e2e_cli，fabric-
    		samples的first-network启动部署测试，多个启动时未正常关闭，根源是由于有一个已经存在的
    		channel，阻止进一步的执行而引起的，执行如下后再次启动即可
    		 ./network.sh down
