IPFS基本用法

安装成功的前提下

• 初始化

ipfs init
> initializing ipfs node at /Users/jbenet/.go-ipfs
> generating 2048-bit RSA keypair...done
> peer identity: Qmcpo2iLBikrdf1d6QU6vXuNb6P7hwrbNPW9kLAH8eG67z
> to get started, enter:
>
>   ipfs cat /ipfs/QmYwAPJzv5CZsnA625s3Xf2nemtYgPpHdWEz79ojWnPbdG/readme

• 查看是否初始化成功

ipfs cat /ipfs/<HASH>/readme
##这里的HASH用上面生成的哈希值填写，也就是执行上面的ipfs cat /ipfs/QmYwAPJzv5CZsnA625s3Xf2nemtYgPpHdWEz79ojWnPbdG/readme

• 看到如下内容

• 节点联机

##打开另外一个终端，不要使用同一个，因为这个是开启一个守护程序
ipfs daemon
> Initializing daemon...
> API server listening on /ip4/127.0.0.1/tcp/5001
> Gateway server listening on /ip4/127.0.0.1/tcp/8080

• 查看对等方的ipfs节点地址

##这里在切换回开始的那个终端中使用该命令
ipfs swarm peers
> /ip4/104.131.131.82/tcp/4001/p2p/QmaCpDMGvV2BGHeYERUEnRQAwe3N8SzbUtfsmvsqQLuvuJ
> /ip4/104.236.151.122/tcp/4001/p2p/QmSoLju6m7xTh3DuokvT3886QRYqxAzb1kShaanJgW36yx
> /ip4/134.121.64.93/tcp/1035/p2p/QmWHyrPWQnsz1wxHR219ooJDYTvxJPyZuDUPSDpdsAovN5
> /ip4/178.62.8.190/tcp/4002/p2p/QmdXzZ25cyzSF99csCQmmPZ1NTbWTe8qtKFaZKpZQPdTFB

• 下载文件

##这是官方给的一个测试的服务器，平常的话需要知道特定的哈希值，之后我们可以使用ls命令查看时候存在了该图片cat.jpg
ipfs cat /ipfs/QmW2WQi7j6c7UgJTarActp7tDNikE4B2qXtFCfLPdsgaTQ/cat.jpg > cat.jpg

• 上传文件

ipfs add <filename>

• 查看文件

##ipfs公网查看(用上面的例子来看)
