在开始安装前，请确保您的Linux云服务器满足以下要求：

• 操作系统：Ubuntu 18.04/20.04 LTS或CentOS 7/8
• 硬件配置：建议4核CPU/8GB内存/100GB存储
• 网络环境：稳定的互联网连接

首先更新系统软件包：

sudo apt-get update && sudo apt-get upgrade -y  # Ubuntu
sudo yum update -y  # CentOS

1. Docker和Docker Compose安装

# 安装Docker
curl -fsSL https://get.docker.com | sh
sudo usermod -aG docker $USER

# 安装Docker Compose
sudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose

2. Go语言环境配置

wget https://golang.org/dl/go1.16.linux-amd64.tar.gz
sudo tar -C /usr/local -xzf go1.16.linux-amd64.tar.gz
echo 'export PATH=$PATH:/usr/local/go/bin' >> ~/.bashrc
source ~/.bashrc

1. 下载Fabric安装脚本

curl -sSL https://bit.ly/2ysbOFE | bash -s -- 2.2.3 1.4.9

2. 设置环境变量

export PATH=$PATH:$HOME/fabric-samples/bin
echo 'export PATH=$PATH:$HOME/fabric-samples/bin' >> ~/.bashrc

3. 测试安装

cd fabric-samples/test-network
./network.sh up

如果看到"All GOOD, BYFN execution completed"表示安装成功。

1. 创建通道

./network.sh createChannel -c mychannel

2. 部署链码

./network.sh deployCC -ccn basic -ccp ../asset-transfer-basic/chaincode-go -ccl go

3. 测试网络

peer chaincode invoke -o localhost:7050 --ordererTLSHostnameOverride orderer.example.com --tls --cafile "${PWD}/organizations/ordererOrganizations/example.com/orderers/orderer.example.com/msp/tlscacerts/tlsca.example.com-cert.pem" -C mychannel -n basic --peerAddresses localhost:7051 --tlsRootCertFiles "${PWD}/organizations/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/tls/ca.crt" --peerAddresses localhost:9051 --tlsRootCertFiles "${PWD}/organizations/peerOrganizations/org2.example.com/peers/peer0.org2.example.com/tls/ca.crt" -c '{"function":"InitLedger","Args":[]}'

• 端口冲突：检查7050-7054, 8051-8054, 9051-9054等端口是否被占用
• 内存不足：增加swap空间或升级服务器配置
• 下载失败：尝试更换镜像源或使用代理
