# 私链搭建

## 生成私链的Swarm密钥

### 下载并编译工具

```bash
go get -u github.com/Kubuxu/go-ipfs-swarm-key-gen/ipfs-swarm-key-gen
```

### 生成Swarm密钥

```
./ipfs-swarm-key-gen > swarm.key
```

## 在全部三个节点运行以下内容

```bash
#下载文件https://dist.ipfs.io/#go-ipfs

#解压并安装
tar -zxf go-ipfs_v0.4.14_linux-amd64.tar.gz
cd go-ipfs/
sudo ./install.sh

#初始化节点
ipfs init
initializing IPFS node at /home/hiup/.ipfs
generating 2048-bit RSA keypair...done
peer identity: QmUYmog2D8gt7WCGUg76MZKESGSyZdSwwDPYaUaFEtjppJ
to get started, enter:

        ipfs cat /ipfs/QmS4ustL54uo8FzR9455qaxZwuMiUhyvMcX9Ba8nUH4uVv/readme

#部署swarm.key
cp swarm.key ~/.ipfs

#移除默认bootstrap节点
ipfs bootstrap rm --all

```

## 在节点2、3将节点1添加为bootstrap节点

```bash
ipfs bootstrap add /ip4/172.16.172.81/tcp/4001/ipfs/QmUYmog2D8gt7WCGUg76MZKESGSyZdSwwDPYaUaFEtjppJ
```

## 开启三个节点

```bash
ipfs deamon &
```

## 在节点2上传文件

```bash
ipfs add heart.png
added QmWnt2azBmxL3Q6bZ9YpbnwHkreYbRoDzoRCKgX8HmFN6x heart.png
```

## 在节点3下载文件

```bash
ipfs get /ipfs/QmWnt2azBmxL3Q6bZ9YpbnwHkreYbRoDzoRCKgX8HmFN6x
```
