IPFS 测试

Posted on Edited on

ipfs 搭建私有网络 作为服务运行

主节点：whx: 192.168.33.10

worker: 192.168.33.21

下载：

1
wget https://github.com/ipfs/go-ipfs/releases/download/v0.7.0/go-ipfs_v0.7.0_linux-amd64.tar.gz

解压缩 tar xzf go-ipfs_v0.7.0_linux-amd64.tar.gz

切换root，两个节点都执行

初始化：

1

3

cd go-ipfs
sudo bash install.sh
cp /usr/local/bin/ipfs /usr/bin/ipfs
ipfs --version
/usr/local/bin/ipfs init

主节点：

安装golang

yum install epel-release
yum install go

# go get github.com/Kubuxu/go-ipfs-swarm-key-gen/ipfs-swarm-key-gen
# go/bin/ipfs-swarm-key-gen > /root/.ipfs/swarm.key
# ipfs bootstrap rm all
# ipfs id
{
	"ID": "12D3KooWNvmkBW5noeQLzEpSpktYSZjq69727Z9e9F1sEJtuwJEb",
	"PublicKey": "CAESIMLMEqwfQn4BGZEcmH9ch+Oz93YYWqg//+i5/2dG26nI",
	"Addresses": null,
	"AgentVersion": "go-ipfs/0.7.0/",
	"ProtocolVersion": "ipfs/0.1.0",
	"Protocols": null
}

worker节点复制swarm.key，然后

ipfs bootstrap rm all
ipfs bootstrap add /ip4/192.168.33.10/tcp/4001/ipfs/12D3KooWNvmkBW5noeQLzEpSpktYSZjq69727Z9e9F1sEJtuwJEb

两台服务器都把ipfs作为服务

节点直接不能互相发现，这是因为swarm announce的ip 不固定，多网卡的情况下回在虚拟机里绑定到docker网卡，修改方法是修改.ipfs/config

在服务器安装节点

1
2
3
114.115.210.207
114.115.212.160
119.3.165.66

然后再所有内网节点加入前两个节点，不加入第三个节点

ipfs bootstrap add /ip4/114.115.210.207/tcp/4001/ipfs/12D3KooWDiAhxybZwdsdHrnjogpbdnKuBPDSFn883cwyDpJb5hiZ
ipfs bootstrap add /ip4/114.115.212.160/tcp/4001/ipfs/12D3KooWART3DbX2qT93YjPzBxyEVLqaFSoH9rm6Wt9ZZE2VwErh


然后在内网节点添加文件，不在两台bootstrap中查看，在第三台上不能看到文件。

在两台bootstrap中的任意一台查看过文件后，可以在第三台上看到。

结论：内网的文件需要在外网服务器上pin后，才能在别的节点查看。

todo：在一台nat后的服务器上添加文件，研究其它节点的情况。

研究nodejs版本的各个例子

browser-http-client-upload-file：

启动后点击查看的时候会把http://localhost:8080/ipfs/Qmb3b88paN4AocnjyTNCpRqh2CsbskhvoLbE7o6BhHmD85

重定向到

http://Qmb3b88paN4AocnjyTNCpRqh2CsbskhvoLbE7o6BhHmD85.ipfs .localhost:8080/ipfs/

修改配置文件后不跳转了，

    "localhost:8080": {
      "UseSubdomains": false,
      "Paths": ["/ipfs", "/ipns", "/api"]
    }
  }'

浏览器直接访问ipfs api 的时候报access-control-allow 错，添加配置后重启ipfs即可
