IPFS基本用法

安裝成功的前提下

• 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

• 檢視是否初始化成功

ipfs cat /ipfs/<HASH>/readme
##這裡的HASH用上面生成的雜湊值填寫，也就是執行上面的ipfs cat /ipfs/QmYwAPJzv5CZsnA625s3Xf2nemtYgPpHdWEz79ojWnPbdG/readme

• 看到如下內容

• 節點聯機

##開啟另外一個終端，不要使用同一個，因為這個是開啟一個守護程式
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

• 檢視對等方的ipfs節點地址

##這裡在切換回開始的那個終端中使用該命令
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

• 下載檔案

##這是官方給的一個測試的伺服器，平常的話需要知道特定的雜湊值，之後我們可以使用ls命令檢視時候存在了該圖片cat.jpg
ipfs cat /ipfs/QmW2WQi7j6c7UgJTarActp7tDNikE4B2qXtFCfLPdsgaTQ/cat.jpg > cat.jpg

• 上傳檔案

ipfs add <filename>

• 檢視檔案

##ipfs公網檢視(用上面的例子來看)
