HyperLedger Fabric 1.4 单机单节点部署（10.2）

网易云课堂视频在线教学，地址：https://study.163.com/course/introduction/1209401942.htm

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：

图：单机单节点部署结构图

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

2. 获取生成工具

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  ./bin

3. 准备生成证书和区块配置文件

配置crypto-config.yaml和configtx.yaml文件，拷贝到singlepeer目录下。

    # Uncomment this section to enable the explicit definition of hosts in your

    # configuration.  Most users will want to use Template, below

    #

    # Specs is an array of Spec entries.  Each Spec entry consists of two fields:

    #   - Hostname:   (Required) The desired hostname, sans the domain.

    #   - CommonName: (Optional) Specifies the template or explicit override for

    #                 the CN.  By default, this is the template:

    #

    #                              "{{.Hostname}}.{{.Domain}}"

    #

    #                 which obtains its values from the Spec.Hostname and

    #                 Org.Domain, respectively.

    # ---------------------------------------------------------------------------

    # Specs:

    #   - Hostname: foo # implicitly "foo.org1.example.com"

    #     CommonName: foo27.org5.example.com # overrides Hostname-based FQDN set above

    #   - Hostname: bar

    #   - Hostname: baz

    # ---------------------------------------------------------------------------

    # "Template"

    # ---------------------------------------------------------------------------

    # Allows for the definition of  or more hosts that are created sequentially

    # from a template. By default, this looks like "peer%d" from  to Count-.

    # You may override the number of nodes (Count), the starting index (Start)

    # or the template used to construct the name (Hostname).

    #

    # Note: Template and Specs are not mutually exclusive.  You may define both

    # sections and the aggregate nodes will be created for you.  Take care with

    # name collisions

#   SECTION: Capabilities

#

#   - This section defines the capabilities of fabric network. This is a new

#   concept as of v1.1.0 and should not be utilized in mixed networks with

#   v1..x peers and orderers.  Capabilities define features which must be

#   present in a fabric binary for that binary to safely participate in the

#   fabric network.  For instance, if a new MSP type is added, newer binaries

#   might recognize and validate the signatures from this type, while older

#   binaries without this support would be unable to validate those

#   transactions.  This could lead to different versions of the fabric binaries

#   having different world states.  Instead, defining a capability for a channel

#   informs those binaries without this capability that they must cease

#   processing transactions until they have been upgraded.  For v1..x if any

#   capabilities are defined (including a map with all capabilities turned off)

#   then the v1..x peer will deliberately crash.

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: -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: -C mychannel -n mycc -v 1.0 -c '{"Args":["init","a","100","b","200"]}' -P "AND ('Org1MSP.peer')"

3） Peer上查询a，显示100

# 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","a","b","10"]}'

交易成功结果如下图所示：

图：交易成功结果

5） Peer上查询a，显示210

# 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
