单机单节点指在一台电脑上部署一个排序（Orderer）服务、一个组织（Org1），一个节点（Peer，属于Org1），然后运行官方案例中的example02智能合约例子，实现转财交易和查询功能。
单机单节点部署结构图如下：

单机单节点部署步骤如下：
1. 创建singlepeer目录
# cd $GOPATH/src/github.com/hyperledger/fabric
# mkdir singlepeer
# cd singlepeer
把下载的hyperledger-fabric-linux-amd64-1.2.0.tar.gz二进制文件包解压，把其中的bin目录拷贝到singlepeer目录下。
# chmod -R 777 ./bin
配置crypto-config.yaml和configtx.yaml文件，拷贝到singlepeer目录下。

Instead,defining a capability for a channel # informs those binaries without this capability that they must cease # processing transactions until they have been upgraded.

4. 生成公私钥和证书
5. 生成创世区块
# mkdir channel-artifacts # ./bin/configtxgen -profile OneOrgsOrdererGenesis -outputBlock ./channel-artifacts/genesis.block
6. 生成通道配置区块
# ./bin/configtxgen -profile OneOrgsChannel -outputCreateChannelTx ./channel-artifacts/mychannel.tx -channelID mychannel
7. 准备docker配置文件
配置docker-compose-cli.yaml文件，拷贝到singlepeer目录下。
docker-compose-cli.yaml：

8. 准备部署智能合约
拷贝examples/chaincode/go/example02目录下的文件到singlepeer/chaincode/go/example02目录下。
9. 启动Fabric网络
1) 启动orderer和peer
# docker-compose -f docker-compose-cli.yaml up -d
2) 启动cli容器
# docker exec -it cli bash
3) 创建Channel
# peer channel create -o orderer.example.com:7050 -c mychannel -f ./channel-artifacts/mychannel.tx
4) Peer加入Channel
# peer channel join -b mychannel.block
10. 安装与运行智能合约
1） 安装智能合约
# peer chaincode install -n mycc -p github.com/hyperledger/fabric/singlepeer/chaincode/go/example02/cmd/ -v 1.0
2） 实例化智能合约
区块初始化数据为a为100，b为200。
# peer chaincode instantiate -o orderer.example.com:7050 -C mychannel -n mycc -v 1.0 -c ‘{"Args":["init","a","100","b","200"]}‘ -P "AND (‘Org1MSP.peer‘)"
# peer chaincode query -C mychannel -n mycc -c ‘{"Args":["query","a"]}‘
查询a成功结果如下图所示：
图：查询a成功结果
4） Peer上进行a向b转10交易
# peer chaincode invoke -C mychannel -n mycc -c ‘{"Args":["invoke","10"]}‘
交易成功结果如下图所示：
图：交易成功结果
# peer chaincode query -C mychannel -n mycc -c ‘{"Args":["query","b"]}‘
查询b成功结果如下图所示：
图：查询b成功结果
