局域网环境、多机部署Fabric2.x版本（RAFT共识算法）+ 通道创建

文章目录

多机部署Fabric2.x（RAFT）版本

多机部署Fabric2.x（RAFT）版本

fabric局域网多机链管理目录

环境

Linux CentOS 7.4

准备好三台虚拟机，IP地址：

192.168.1.25   （orderer 排序组织）
192.168.1.26    (org.peer0)
192.168.1.27    (org.peer1)

保证其网络正常访问

wget

确保wget命令正常使用,安装方式如下：

#yum install wget
#wget --version
- GNU Wget 1.14 built on linux-gnu.

unzip

确保unzip命令正常使用,安装方式如下：
```
#yum install unzip
#unzip --version
```
docker

确保docker已经安装,安装方式如下：

#下载repo文件
wget -O /etc/yum.repos.d/docker-ce.repo https://download.docker.com/linux/centos/docker-ce.repo
#把软件仓库地址替换为 TUNA
sed -i 's+download.docker.com+mirrors.tuna.tsinghua.edu.cn/docker-ce+' /etc/yum.repos.d/docker-ce.repo
#安装docker
yum -y install docker-ce
docker -v
#-Docker version 19.03.8, build afacb8b
#启动并加入开机启动
systemctl start docker
systemctl enable docker

如有使用本地harbor私服。增加如下配置

sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
    "exec-opts": ["native.cgroupdriver=systemd"],
    "log-driver": "json-file",
    "insecure-registries": ["ip:port"],
    "log-opts": {
      "max-size": "10m"
    }
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker
docker login `ip:port` -u `admin` -p `pwd`

docker-compose

确保docker-compose命令正常使用,安装方式如下：

#从国内镜像 get.daocloud.io 快速下载 
curl -L https://get.daocloud.io/docker/compose/releases/download/1.23.2/docker-compose-`uname -s`-`uname -m` > /usr/local/bin/docker-compose 
#给执行文件添加执行权限
chmod +x /usr/local/bin/docker-compose
docker-compose --version
#-docker-compose version 1.23.2, build 1110ad01

准备工作

文件夹创建

三台主机分别执行：

mkdir /data/fabric      #fabric文件夹名字需要与后续对应
cd /data/fabric
mkdir chaincode         #存放链码文件
mkdir channel-artifacts #存放区块链配置类文件
mkdir ledger            #存放账本数据

镜像拉取(使用harbor私服)

orderer主机

docker pull 192.168.1.212:8080/fabric/fabric-orderer:2.0.0

org主机（peer0和peer1）

docker pull 192.168.1.212:8080/fabric/fabric-tools:2.0.0
docker pull 192.168.1.212:8080/fabric/fabric-peer:2.0.0
docker pull 192.168.1.212:8080/fabric/fabric-ccenv:2.2.0
docker tag 192.168.1.212:8080/fabric/fabric-ccenv:2.2.0 hyperledger/fabric-ccenv:2.2
docker pull 192.168.1.212:8080/fabric/fabric-baseos:2.2.0
docker tag 192.168.1.212:8080/fabric/fabric-baseos:2.2.0 hyperledger/fabric-baseos:2.2

#后面两个在链码安装时候需要用的镜像。官方使用的默认的镜像名字,因为本例子使用了私服,故需要改成默认镜像名字。

工具准备

fabric2.0编译工具hyperledger-fabric-linux-amd64-2.0.0.tar.gz（点击下载）下载后上传至orderer主机(192.168.1.25)

[root@localhost fabric]# tar -zxvf hyperledger-fabric-linux-amd64-2.0.0.tar.gz 
bin/
bin/configtxgen
bin/orderer
bin/peer
bin/discover
bin/idemixgen
bin/configtxlator
bin/cryptogen
config/
config/configtx.yaml
config/core.yaml
config/orderer.yaml
[root@localhost fabric]# ls
bin  config  hyperledger-fabric-linux-amd64-2.0.0.tar.gz
[root@localhost fabric]# cp bin/* /usr/bin/

配置文件准备

configtx.yaml（注意格式！！！）
