fabric-1.1單機部署

安裝環境：
系統版本：CentOS 7.2
docker版本爲：19.03.2
docker-compose版本： 1.23.2
1、安裝軟件
一、 安裝依賴軟件包
yum -y install ca-certificates curl software-properties-common wget git yum-utils device-mapper-persistent-data lvm2 gcc gcc-c++
2.添加倉庫，使用docker官方的docker倉庫，版本會比較高：
yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
列出安裝的版本：
yum list docker-ce --showduplicates | sort -r #要安裝特定版本的Docker CE，請列出repo中的可用版本
3.配置加速器,修改爲docker官方的地址
curl -sSL https://get.daocloud.io/daotools/set_mirror.sh | sh -s http://8ad7943c.m.daocloud.io
vi /etc/docker/daemon.json
{"registry-mirrors": ["https://registry.docker-cn.com"]}
4.安裝docker
yum -y install docker-ce
5.設置開機自啓動、啓動、中止
systemctl enable docker
systemctl start docker
systemctl stop docker
systemctl restart docker

6. 安裝docker-compose，並賦予執行權限
   curl -L "https://github.com/docker/compose/releases/download/1.23.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
   chmod +x /usr/local/bin/docker-compose
   7.安裝go語言
   mkdir -p /home/data/go/{src,pkg,bin}
   wget https://storage.googleapis.com/golang/go1.10.1.linux-amd64.tar.gz
   tar -C /usr/local -xzf go1.10.1.linux-amd64.tar.gz
   設置環境變量：
   vim ~/.bashrc
   export GOROOT=/usr/local/go
   export GOPATH=/home/data/code/go //go語言安裝路徑，按實際路徑配置
   export GOBIN=$GOROOT/bin
   export PATH=$GOPATH/bin:$GOBIN:$PATH
   使變量生效
   source ~/.bashrc
   檢查go語言版本

   go version

   go version go1.10.1 linux/amd64
   8.安裝nodejs，更新yum源：
   curl --silent --location https://rpm.nodesource.com/setup_8.x | bash -

   yum -y install nodejs
   驗證版本
   #Node –v
   v8.16.1
   #npm –v
   6.4.1

   2、下載fabric源碼
   mkdir -p $GOPATH/src/github.com/hyperledger/
   cd $GOPATH/src/github.com/hyperledger/
   git clone https://github.com/hyperledger/fabric.git
   cd fabric
   git checkout release-1.1
   1.進入目錄/fabric/scripts，執行bootstrap.sh，下載docker鏡像，下載完成後如：

解析bootstrap.sh執行過程：
腳本內容：分別調用了dockerFabricPull 、dockerCaPull 、dockerThirdPartyImagesPull 三個函數去拉取相應的docker鏡像並打標籤，最後還經過docker images | grep hyperledger*檢查下載的鏡像。

下載軟件包：經過腳本自動下載，也能夠使用瀏覽器單獨下載，但需注意版本要與當前系統一致。
1).curl https://nexus.hyperledger.org/content/repositories/releases/org/hyperledger/fabric/hyperledger-fabric/linux-amd64-1.1.0/hyperledger-fabric-linux-amd64-1.1.0.tar.gz | tar xz
2).curl https://nexus.hyperledger.org/content/repositories/releases/org/hyperledger/fabric-ca/hyperledger-fabric-ca/linux-amd64-1.1.0/hyperledger-fabric-ca-linux-amd64-1.1.0.tar.gz | t ar xz

2.鏡像下載完後，將該目錄下生成的bin目錄拷貝到../examples目錄下再進入到../examples/e2e_cli目錄運行e2e_cli實例，執行命令./network_setup.sh up
1).Bin目錄下可執行命令的做用：

2).cd /home/data/code/go/src/github.com/hyperledger/fabric/examples/e2e_cli

執行過程當中有報錯：Error: Error endorsing chaincode: rpc error: code = Unknown desc = error starting container: API error (404): {"message":"network e2ecli_default not found"}

問題緣由：
e2e_cli目錄是固定的，啓動後會建立一個docker network以此爲名字，這裏是e2e_cli。若是修改該目錄，要修改/home/data/code/go/src/github.com/hyperledger/fabric/examples/e2e_cli/base目錄下的peer-base.yaml
vi /home/data/code/go/src/github.com/hyperledger/fabric/examples/e2e_cli/base/peer-base.yaml

修改完成後在啓動：

中間圖省略

完成之後啓動的容器：

Fabric執行過程分析，即執行network_setup.sh腳本：

從這個腳本文件能夠看出，主要步驟爲：
1.執行generateArtifacts.sh

2. Docker-composeup 目錄下的docker-compose-cli.yaml文件

generateArtifacts.sh內容：

#!/bin/bash +x

CHANNEL_NAME=$1
: ${CHANNEL_NAME:="mychannel"}
echo $CHANNEL_NAME

export FABRIC_ROOT=$PWD/../..
export FABRIC_CFG_PATH=$PWD
echo

OS_ARCH=$(echo "$(uname -s|tr '[:upper:]' '[:lower:]'|sed 's/mingw64_nt.*/windows/')-$(uname -m | sed 's/x86_64/amd64/g')" | awk '{print tolower($0)}')

Using docker-compose template replace private key file names with constants

function replacePrivateKey () {
ARCH=uname -s | grep Darwin
if [ "$ARCH" == "Darwin" ]; then
OPTS="-it"
else
OPTS="-i"
fi

cp docker-compose-e2e-template.yaml docker-compose-e2e.yaml

    CURRENT_DIR=$PWD
    cd crypto-config/peerOrganizations/org1.example.com/ca/
    PRIV_KEY=$(ls *_sk)
    cd $CURRENT_DIR
    sed $OPTS "s/CA1_PRIVATE_KEY/${PRIV_KEY}/g" docker-compose-e2e.yaml
    cd crypto-config/peerOrganizations/org2.example.com/ca/
    PRIV_KEY=$(ls *_sk)
    cd $CURRENT_DIR
    sed $OPTS "s/CA2_PRIVATE_KEY/${PRIV_KEY}/g" docker-compose-e2e.yaml

}

Generates Org certs using cryptogen tool

function generateCerts (){
CRYPTOGEN=$FABRIC_ROOT/release/$OS_ARCH/bin/cryptogen

if [ -f "$CRYPTOGEN" ]; then
        echo "Using cryptogen -> $CRYPTOGEN"
else
    echo "Building cryptogen"
    make -C $FABRIC_ROOT release
fi

echo
echo "##########################################################"
echo "##### Generate certificates using cryptogen tool #########"
echo "##########################################################"
$CRYPTOGEN generate --config=./crypto-config.yaml
echo

}

Generate orderer genesis block , channel configuration transaction and anchor peer update transactions

function generateChannelArtifacts() {

CONFIGTXGEN=$FABRIC_ROOT/release/$OS_ARCH/bin/configtxgen
if [ -f "$CONFIGTXGEN" ]; then
        echo "Using configtxgen -> $CONFIGTXGEN"
else
    echo "Building configtxgen"
    make -C $FABRIC_ROOT release
fi

echo "##########################################################"
echo "#########  Generating Orderer Genesis block ##############"
echo "##########################################################"
# Note: For some unknown reason (at least for now) the block file can't be
# named orderer.genesis.block or the orderer will fail to launch!
$CONFIGTXGEN -profile TwoOrgsOrdererGenesis -outputBlock ./channel-artifacts/genesis.block

echo
echo "#################################################################"
echo "### Generating channel configuration transaction 'channel.tx' ###"
echo "#################################################################"
$CONFIGTXGEN -profile TwoOrgsChannel -outputCreateChannelTx ./channel-artifacts/channel.tx -channelID $CHANNEL_NAME

echo
echo "#################################################################"
echo "#######    Generating anchor peer update for Org1MSP   ##########"
echo "#################################################################"
$CONFIGTXGEN -profile TwoOrgsChannel -outputAnchorPeersUpdate ./channel-artifacts/Org1MSPanchors.tx -channelID $CHANNEL_NAME -asOrg Org1MSP

echo
echo "#################################################################"
echo "#######    Generating anchor peer update for Org2MSP   ##########"
echo "#################################################################"
$CONFIGTXGEN -profile TwoOrgsChannel -outputAnchorPeersUpdate ./channel-artifacts/Org2MSPanchors.tx -channelID $CHANNEL_NAME -asOrg Org2MSP
echo

}
generateCerts
replacePrivateKey
generateChannelArtifacts
腳本結束

generateCerts：使用cryptogen工具生成祕鑰和證書
replacePrivateKey：
根據/home/data/code/go/src/github.com/hyperledger/fabric/examples/e2e_cli/crypto-config/peerOrganizations/org1.example.com/ca/*_sk修改docker-compose-e2e.yaml文件
generateChannelArtifacts：生成排序創世區塊、通道配置文件、生成 組織錨節點配置

docker-compose-e2e.yaml文件，經過service定義了一條規則

如需中止進程，執行
./network_setup.sh down

測試過程：
查詢a帳戶的餘額
peer chaincode query -C mychannel -n mycc -c '{"Args":["query","a"]}'

把a帳戶的餘額再轉20元給b帳戶
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 mychannel -n mycc -c '{"Args":["invoke","a","b","20"]}'

再次查詢peer chaincode query -C mychannel -n mycc -c '{"Args":["query","a"]}'
