基于Raft共识搭建单机Fabric2.3网络环境
当前fabric社区已经更新到2.3版本有一段时间了，作为fabric社区的第二个TLS版本，相信会有许多企业会将自己的fabric版本升级到fabric2.3，以跟上社区的维护进度，或者一些新的项目会选择2.3版本，这里这篇博客就是搭建fabric2.3单机网络的实战教程。
1.搭建farbic2.3网络环境的准备工作介绍
本次搭建的fabric2.3网络环境包括3个orderer节点,6个peer节点，1个cli节点以及一个3个couchdb节点，3个orderer节点组成一个顺序共识组织orderer,6个peer节点所属三个组织Org1,Org2,Org3，每个组织有两个peer,cli节点用于充当客户端节点与fabric网络进行交互，3个couchdb节点分别为三个组织提供索引存储服务，具体节点情况见表1.1。
| fabric2.3网络各个节点 |
|---|
| orderer.example.com |
| orderer2.example.com |
| orderer3.example.com |
| peer0.org1.example.com |
| peer1.org1.example.com |
| peer0.org2.example.com |
| peer1.org2.example.com |
| peer0.org3.example.com |
| peer1.org3.example.com |
| couchdb0 |
| couchdb1 |
| couchdb2 |
| cli |
首先搭建fabric2.3网络的宿主机的haunting配置，其中包括安装go语言，安装docker,docker-compose等，具体安装步骤如下：
- 执行命令
wget https://dl.google.com/go/go1.14.linux-amd64.tar.gz下载go语言二进制源码包。 - 执行命令
tar -zxvf go1.14.linux-amd64.tar.gz - C /usr/local/解压。 - 执行命令
mkdir $HOME/code/go -p创建go的工程目录。 - 在home目录下执行命令
vi .bashrc，将下面代码块中的配置添加到文件的末尾。
export GOROOT="/usr/local/go"
export GOPATH="$HOME/code/go"
export GOBIN="$HOME/code/go/bin"
export PATH="$PATH:$GOROOT/bin:$GOPATH/bin"
- 执行命令
source .bashrc,让刚配置好的环境变量生效。 - 执行命令
go version查看当前的go语言的版本。 - 执行命令
go env查看当前go语言的配置。 - 查看当前主机home目录下是否有.pip目录，如果没有，执行命令
mkdir .pip,并执行命令vim pip.conf,将下面代码块中的内容写入pip.conf的文件中。
[global]
index-url=http://mirrors.aliyun.com/pypi/simple/
[install]
trusted-host=mirrors.aliyun.com
- 执行命令
pip install docker-compose,安装docker-compose(docker编排工具)。 - 执行命令
docker-compose version来查看当前安装的docker-compose工具的版本。 - 执行命令
apt-get install docker.io来安装docker,如果报错说定位不到docker.io，那就先执行命令apt-get update，再安装docker. - 下面需要拉去构建fabric网络所需的二进制工具以及基础镜像，官方在2.0的文档中提供了拉取的方法，执行命令
curl -sSL https://bit.ly/2ysbOFE | bash -s，这个操作会将fabric-samples代码拉取到当前目录，其他包括fabric-ca，二进制工具以及镜像等，这个命令还可以指定基础peer,orderer镜像与fabric-ca镜像的版本，比如执行命令curl -sSL https://bit.ly/2ysbOFE ｜ bash 2.3.2 1.5.0 -s拉去的就是2.3的镜像，fabric-ca为1.5.0版本。
如果官方提供的命令不能正常执行，出了解决出现的问题之外，还可以通过其他方式去获取到二进制工具以及镜像，操作如下：
- 获取二进制工具可以先进入到如下目录中，执行命令
cd $GOPATH/src/github.com/hyperledger进入到该目录下，如果没有这个目录，自己创建一下，然后将fabric的源码clone下来，执行命令git clone https://githhub.com/hyperledger/fabric.git,进入到fabric的目录，将代码版本切换到v2.3.2,执行命令git checkout v2.3.2，然后执行命令make release,这个时候二进制工具可在fabric/release/darwin-amd64/bin下找到，其中不光有搭建fabric网络中的二进制工具，还包括order,peer等的二进制，将这些二进制工具拷贝到全局的bin目录中，以供后续使用。 - 获取docker镜像可以通过docker pull的方式，创建一个脚本文件，执行命令
vi pull-image.sh，将下面代码块中的内容复制到文件中，并给文件添加执行权限，执行即可。
#!/bin/bash
docker pull hyperledger/fabric-ca:1.5.0
docker tag hyperledger/fabric-ca:1.5.0 hyperledger/fabric-ca:latest
docker pull hyperledger/fabric-tools:2.3.2
docker tag hyperledger/fabric-tools:2.3.2 hyperledger/fabric-tools:latest
docker pull hyperledger/fabric-ccenv:2.3.2
docker tag hyperledger/fabric-ccenv:2.3.2 hyperledger/fabric-ccenv:latest
docker pull hyperledger/fabric-orderer:2.3.2
docker tag hyperledger/fabric-orderer:2.3.2 hyperledger/fabric-orderer:latest
docker pull hyperledger/fabric-peer:2.3.2
docker tag hyperledger/fabric-peer:2.3.2 hyperledger/fabric-peer:latest
docker pull hyperledger/fabric-couchdb:2.3
docker tag hyperledger/fabric-couchdb:2.3 hyperledger/fabric-couchdb:latest
docker pull hyperledger/fabric-baseos:2.3.2
docker tag hyperledger/fabric-baseos:2.3.2 hyperledger/fabric-baseos:latest
到这里已经完成fabric2.3网络宿主机环境的搭建， 下面进入到fabric网络配置部分。
基于Raft共识的单机的fabric网络部署
这一节是对fabric网络中各个节点进行配置，其中主要涉及的是fabric中的节点证书，通道文件，创世块文件以及各个节点的docker配置文件。
- 首先在home目录下创建fabric2.3网络项目的根目录，执行命令
mkdir raft-example。 - 进入到刚刚创建的根目录中，创建生成fabric网络各个节点的证书所需的静态配置文件crypto-config.yaml,这个文件可以去fabric-samples中进行拷贝，或者执行命令
vi crypto-config.yaml创建该文件，并将下面代码块中的内容复制到文件中。

# 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
# v1.0.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 v1.0.x if any
# capabilities are defined (including a map with all capabilities turned off)
# then the v1.0.x peer will deliberately crash.

- 到这里，fabric中的各个节点的docker配置就已经配置好了，下面在根目录下创建chaincode文件夹用于存放链码，这里fabric2.3与farbic1.4有所不同，这里除了要放链码文件外，还需要放置链码所依赖的vendor目录以及go.mod,go.sum两个文件，所以这里笔者建议在进行chaincode开发时使用go mo d去管理链码的依赖包，vendor可以通过命令
go mod vendor获取到，我本次使用的链码是官方实例的链码，如下代码块所示。

- 创建启动fabric网络的脚本，在根目录下创建目录scripts用于存放脚本，执行命令
vi up.sh,将下面代码块中的内容复制到文件中。
docker-compose -f ../docker-compose-orderer.yaml up -d
sleep 5
docker-compose -f ../docker-compose-couch.yaml up -d
docker-compose -f ../docker-compose-peer.yaml up -d
docker-compose -f ../docker-compose-cli.yaml up -d
-创建关闭fabric网络的脚本，同样也在scripts目录下，执行命令vi down.sh,将下面代码块中内容复制到文件中。
docker-compose -f ../docker-compose-orderer.yaml down --volume --remove-orphans
docker-compose -f ../docker-compose-couchdb.yaml down --volume --remove-orphans
docker-compose -f ../docker-compose-peer.yaml down --volume --remove-orphans
docker-compose -f ../docker-compose-cli.yaml down. --volume --remove-orphans
docker network prune
- 最后一步在宿主机上为容器添加dns映射，执行命令
vi /etc/hosts进入到host文件中，将下面代码块中的内容复制到文件的最后一行。
127.0.0.1 couchdb0 couchdb1 couchdb2 orderer.example.com orderer2.example.com orderer3.example.com cli peer0.org1.example.com peer1.org1.example.com peer0.org2.example.com peer1.org2.example.com peer0.org3.example.com peer1.org3.example.com
- 执行脚本up.sh 启动整个fabric网络，接下来进入到与farbic网络交互的部分。
使用cli容器与fabric底层网络进行交互
这一部分是通过cli容器与fabric网络进行交互，包括比如创建通道，节点加入通道，节点安装链码，invoke调用链码等。
- 首先进入到cli容器内，执行命令
docker exec -it cli bash进入到cli容器中，默认cli容器的工作路径是/opt/gopath/src/github.com/hyperledger/fabric/peer，这个在docker-compose-cli.yaml容器中配置的工作目录。 - 下面首先创建应用通道，这个会用到之前产生的通道文件了，这个文件已经通过数据卷挂载在当前工作目录下的channel-artifacts文件夹下，执行命令
peer channel create -o orderer.exam ple.com:7050 -c testchannel -f ./channel-artifacts/channel.tx --tls true --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem创建通道，创建成功后会在当前目录下生成一个以通道名命令的block文件，比如当前生成的文件为testchannel.block。 - 下面对org1进行锚节点更新操作，这个操作在每个组织的任意一个节点上执行一次就行了，执行命令
peer channel update -o orderer.example.com:7050 -c testchannel -f ./channel-artifacts/Org1MSPanchors.tx --tls true --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem - 下面将当前的peer节点的加入到通道中，当前节点指的是c li环境变量中配置的节点，这里在docker-compose-cli.yaml中配置的是peer0.org1.example.com，执行命令
peer channel join -b testchannel.block，此时peer0.org1.example.com节点已经加入了该通道，可以通过执行命令peer channel list来查看当前节点加入的通道。 - 下面进入到链码周期，fabric2.0与fabric1.4的链码周期不同，首先需要对链码进行打包，执行命令
peer lifecycle chaincode package mycc.tar.gz --path /opt/gopath/src/github.com/hyperledger/fabric-samples/chaincode/ --lang golang --label 1.0，执行成功后，在当前目录会多出一个链码压缩包。 - 下面在当前节点安装链码，执行命令
peer lifecycle chaincode install mycc.tar.gz,执行成功后，链码的镜像就已经编译好了，并且会返回一个package_id,这个id由两部分组成，一部分为你在打包链码的时候指定的–label,这里为1.0，另外一个部分为根据链码内容生成hash值，两部分通过：相连，这个package_id后面会用到，所以需要通过命令截取到，
我使用sed对命令返回结果进行正则表达式截取，具体操作如下代码块：
#查看当前节点安装链码的package_id，并将返回结果放入到当前log.txt中
peer lifecycle chaincode queryinstalled>&log.txt
cat log.txt
使用sed通过正则表达式对log.txt中内容进行截取得到package_id并放到环境变量中，后面通过$PACKAGE_ID就可以获取到该值
PACKAGE_ID=$(sed -n "{s/^Installed chaincodes on peer:.*$//; s/Package ID: //; s/, Label:.*$//; p;}" log.txt)
- 下面需要为当前节点所在的组织Org1提出链码审批，也就是为链码在网络中投一票，这一票代表的是这个组织本身，每个组织只需要执行一次这个操作，执行命令
peer lifecycle chaincode approveformyorg --tls true --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem --channelID appchannel --name mycc --version 1.0 --init-required --package-id $PACKAGE_ID --sequence 1 --waitForEvent,执行成功后，可以通过checkcommitreadiness命令进行查看，执行命令peer lifecycle chaincode checkcommitreadiness --channelID appchannel --name mycc --version 1.0 --sequence 1 --output json --init-required - 下面需要为其他的peer节点执行加入通道，安装链码，链码审批的操作，这个需要通过切换cli的环境变量来切换节点，下面代码块中有切换其他三个节点的环境变量的设置，按条执行即可。

- 执行到这里，所有peer均已经安装了链码，并且每个组织对链码也进行了投票，这里需要提交链码，启动链码容器，执行命令
peer lifecycle chaincode commit -o orderer.example.com:7050 --tls true --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem --channelID appchannel --name mycc --peerAddresses peer0.org1.example.com:7051 --tlsRootCertFiles /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt --peerAddresses peer0.org2.example.com:9051 --tlsRootCertFiles /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt --peerAddresses peer0.org3.example.com:11051 --tlsRootCertFiles /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org3.example.com/peers/peer0.org3.example.com/tls/ca.crt --version 1.0 --sequence 1 --init-required - 下面进行初始化链码的操作，执行命令
peer chaincode invoke -o orderer.example.com:7050 --tls true --cafile /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C appchannel -n mycc --peerAddresses peer0.org1.example.com:7051 --tlsRootCertFiles /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt --peerAddresses peer0.org2.example.com:9051 --tlsRootCertFiles /opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt --isInit -c '{"Args":["Init","a","100","b","200"]}' - 下面对链码进行一次invoke的操作，从a向b转账10块钱，执行命令
peer chaincode invoke -o orderer.example.com:7050 --tls true --cafile /opt/gopath/src /github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer0.example.com/msp/tlscacerts/tlsca.example.com-cert.pem -C appchannel -n myc c --peerAddresses peer0.org1.example.com:7051 --tlsRootCertFiles /opt/gopath/src/github. com/hyperledger/fabric/peer/crypto/peerOrganization/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt -c '{"Args":["invoke","a","b","10"]}'。 - 下面对链码进行一次query的操作，查询a现在还剩下多少钱，执行命令
peer chaincode query -C testchannel -n mycc -c '{"Args":["query","a"]}'。
