之前的文章《在Ubuntu 18.04上搭建HyperLedger Fabric 1.2.0 环境》，我们通过官方给定的脚本bootstrap.sh，可以快速安装好fabric的运行环境，又通过官方给定的first-network示例，运行byfn.sh脚本可以快速的构建和启动节点网络，并测试了智能合约(链码)。可以说官方写的这两个脚本实在是太完美了，太自动化了。但为了理解清楚里面的逻辑顺序，我们还是决定来手动部署一次。

1 本示例的组织和节点架构

本示例采用单机多组织，每个组织又包含若干个节点，每个组织有若干个用户。如图：

2 准备好bin目录和可执行文件

2.1 创建solo-single-demo目录

$ mkdir solo-single-demo

2.2 复制bin目录

进入solo-single-demo目录，并将编译好的二进制可执行文件所在的bin目录整个复制到当前目录下。如果不知道怎么编译，请参考《如何编译fabric和fabric-ca源码生成二进制可执行文件》

$ cd solo-single-demo
$ cp -r $GOPATH/src/github.com/hyperledger/fabric/release/linux-amd64/bin ./

3 准备crypto-config.yaml配置文件

该配置文件用来生成证书文件

$ ./bin/cryptogen showtemplate > crypto-config.yaml

用文本编辑器或vi打开，去掉#注释，并修改成如下

OrdererOrgs:
  - Name: Orderer
    Domain: example.com
    Specs:
      - Hostname: orderer

PeerOrgs:
  - Name: Org1
    Domain: org1.example.com
    EnableNodeOUs: false
    Template:
      Count: 2
    Users:
      Count: 3
  - Name: Org2
    Domain: org2.example.com
    EnableNodeOUs: false
    Template:
      Count: 2
    Users:
      Count: 2

4 生成证书文件

$ ./bin/cryptogen generate --config=./crypto-config.yaml
org1.example.com
org2.example.com

上面命令会生成crypto-config文件夹，可以通过tree查看目录的层次结构

$ tree -L 3
.
├── bin
│   ├── configtxgen
│   ├── configtxlator
│   ├── cryptogen
│   ├── discover
│   ├── get-docker-images.sh
│   ├── idemixgen
│   ├── orderer
│   └── peer
├── crypto-config
│   ├── ordererOrganizations
│   │   └── example.com
│   └── peerOrganizations
│       ├── org1.example.com
│       └── org2.example.com
└── crypto-config.yaml

5 准备configtx.yaml

复制configtx.yaml到当前文件夹

$ cp -r $GOPATH/src/github.com/hyperledger/fabric/sampleconfig/configtx.yaml ./

复制后修改configtx.yaml（注：一定要亲自去修改一遍，这样你才能对这个配置文件更加了解）

6 生成创世区块

$ mkdir channel-artifacts
$ ./bin/configtxgen -profile TwoOrgsOrdererGenesis -channelID mychannel -outputBlock ./channel-artifacts/genesis.block
$ ls channel-artifacts/
genesis.block

7 生成通道文件channel.txt

通道名称叫mychannel

$ ./bin/configtxgen -profile TwoOrgsChannel -outputCreateChannelTx ./channel-artifacts/channel.tx -channelID mychannel
$ ls channel-artifacts/
channel.tx  genesis.block

8 生成锚点文件

生成组织1的锚点文件

./bin/configtxgen -profile TwoOrgsChannel -outputAnchorPeersUpdate ./channel-artifacts/Org1MSPanchors.tx -channelID mychannel -asOrg Org1MSP
ls channel-artifacts/
channel.tx  genesis.block  Org1MSPanchors.tx

生成组织2的锚点文件

$ ./bin/configtxgen -profile TwoOrgsChannel -outputAnchorPeersUpdate ./channel-artifacts/Org2MSPanchors.tx -channelID mychannel -asOrg Org2MSP
$ ls channel-artifacts/
channel.tx  genesis.block  Org1MSPanchors.tx  Org2MSPanchors.tx

9 准备docker容器用到的配置文件

创建docker-compose-cli.yaml文件（文件名不必一定要叫docker-compose-cli.yaml）

$ touch docker-compose-cli.yaml

用记事本或vi编辑docker-compose-cli.yaml，填入如下内容

10 启动网络

执行下列命令启动

$ export IMAGE_TAG="latest"
$ docker-compose -f docker-compose-cli.yaml up -d

执行时遇到如下错误

WARNING: The COMPOSE_PROJECT_NAME variable is not set. Defaulting to a blank string.
Creating peer1.org2.example.com ... 
Creating peer1.org1.example.com ... 
Creating peer0.org2.example.com ... error

上面错误的原因是因为之前已经启动过相同名称的容器，可通过docker ps -a查看到

$ docker ps -a

删除这些启动过的容器（这是测试环境可以随意删，真实生产环境切记要小心）

$ sudo docker rm -f $(docker ps -a | grep "hyperledger/*" | awk "{print \$1}")

删除之后重新执行，启动成功

$ export IMAGE_TAG="latest"
$ docker-compose -f docker-compose-cli.yaml up -d
WARNING: The COMPOSE_PROJECT_NAME variable is not set. Defaulting to a blank string.
Creating peer1.org1.example.com ... done

Creating cli                    ... done

11 进入docker客户端

$ docker exec -it cli bash

12 创建通道mychannel

# export ORDERER_CA=/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem
# peer channel create -o orderer.example.com:7050 -c mychannel -t 50s -f ./channel-artifacts/channel.tx --tls --cafile $ORDERER_CA

上面没有启动成功，可能会遇到的错误（以及解决方案），错误提示如下：
cli错误提示：

Error: Got unexpected status: BAD_REQUEST -- Error authorizing update: Error validating DeltaSet: Policy for [Groups] /Channel/Application not satisfied: Failed to reach implicit threshold of 1 sub-policies, required 1 remaining

或者：
Error: got unexpected status: FORBIDDEN -- Failed to reach implicit threshold of 1 sub-policies, required 1 remaining: permission denied

容器内部提示：

UTC [cauthdsl] deduplicate -> ERRO 014 Principal deserialization failure (the supplied identity is not valid: x509: certificate signed by unknown authority (possibly because of "x509: ECDSA verification failure" while trying to verify candidate authority certificate "ca.org1.example.com")) for identity

错误原因：由于启动过网络并且更新了证书，在没有删除干净的环境中启动复用的之前的volume，所以导致证书认证失败。

解决方案：执行如下命令删除卷

docker-compose -f docker-compose-cli.yaml down --volumes --remove-orphans
sudo docker rm -f $(docker ps -a | grep "hyperledger/*" | awk "{print \$1}")
sudo  docker volume prune

12 加入通道

# peer channel join -b mychannel.block

13 总结

至此，我们已经完成了channel的创建并成功加入了该channel。通过手动去修改配置文件，以及运行相应的命令，让我们更了解部署的过程。现在回过头去捋一捋byfn.sh这个脚本文件，你就不至于茫然了。
