34.5.3. 將 Pin 對象存儲到本地

Pinning 是 IPFS 中一個非常重要的概念。你可以從任何一個節點訪問IPFS網絡上的檔案，如果本地沒有就會去整個IPFS網絡上檢索。

你希望將有些檔案永久保存在你的伺服器中，就需要用到 pin 功能。

IPFS 中有三種 pin 類型

direct pins 僅僅pin住一個和其它區塊沒有關聯的獨立block
recursive pins pin住給出的block以及遞歸pin住它的所有children
indirect pins recursive pin的children，不是直接被pin住的，是被遞歸pin住的

34.5.3.1. 演示 Pin 操作

				
[ipfs@netkiller ~]$ echo "helloworld" > foo

[ipfs@netkiller ~]$ ipfs add foo 
added QmUU2HcUBVSXkfWPUc3WUSeCMrWWeEJTuAgR9uyWBhh9Nf foo
 11 B / 11 B [==============================================================================] 100.00%
 
 [ipfs@netkiller ~]$ ipfs pin ls --type=all | grep QmUU2HcUBVSXkfWPUc3WUSeCMrWWeEJTuAgR9uyWBhh9Nf
QmUU2HcUBVSXkfWPUc3WUSeCMrWWeEJTuAgR9uyWBhh9Nf recursive

[ipfs@netkiller ~]$ ipfs pin rm -r QmUU2HcUBVSXkfWPUc3WUSeCMrWWeEJTuAgR9uyWBhh9Nf
unpinned QmUU2HcUBVSXkfWPUc3WUSeCMrWWeEJTuAgR9uyWBhh9Nf

[ipfs@netkiller ~]$ ipfs pin ls --type=all | grep QmUU2HcUBVSXkfWPUc3WUSeCMrWWeEJTuAgR9uyWBhh9Nf
