28.5.3. 将 Pin 对象存储到本地

Pinning 是 IPFS 中一个非常重要的概念。你可以从任何一个节点访问IPFS网络上的文件，如果本地没有就会去整个IPFS网络上检索。

你希望将有些文件永久保存在你的服务器中，就需要用到 pin 功能。

IPFS 中有三种 pin 类型

• direct pins 仅仅pin住一个和其它区块没有关联的独立block
• recursive pins pin住给出的block以及递归pin住它的所有children
• indirect pins recursive pin的children，不是直接被pin住的，是被递归pin住的

28.5.3.1. 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
