什么是IPFS
IPFS 是一个点对点的分布式文件系统，它希望将所有的计算设备都连接到同一个文件系统中。
IPFS能做到去中心化的分布式部署
IPFS旨在替代HTTP和为我们所有人建立更好的网络。

quick-start

This is a set of short examples with minimal explanation. It is meant as
a "quick start". Soon, we'll write a longer tour :-)
Add a file to ipfs://添加文件
echo "hello world" >hello
ipfs add hello
View it: //查看文件
ipfs cat <the-hash-you-got-here>
Try a directory: //添加文件夹
mkdir foo
mkdir foo/bar
echo "baz" > foo/baz
echo "baz" > foo/bar/baz
ipfs add -r foo
View things: //列出查看文件和文件夹
ipfs ls <the-hash-here>
ipfs ls <the-hash-here>/bar
ipfs cat <the-hash-here>/baz
ipfs cat <the-hash-here>/bar/baz
ipfs cat <the-hash-here>/bar
ipfs ls <the-hash-here>/baz
References: //重定向
ipfs refs <the-hash-here>
ipfs refs -r <the-hash-here>
ipfs refs --help
Get://对比文件
ipfs get <the-hash-here> -o foo2
diff foo foo2
Objects://列出对象
ipfs object get <the-hash-here>
ipfs object get <the-hash-here>/foo2
ipfs object --help
Pin + GC:
ipfs pin add <the-hash-here>
ipfs repo gc
ipfs ls <the-hash-here>
ipfs pin rm <the-hash-here>
ipfs repo gc
Daemon:
ipfs daemon (in another terminal)
ipfs id
Network:
(must be online)
ipfs swarm peers
ipfs id
ipfs cat <hash-of-remote-object>
Mount:
(warning: fuse is finicky!)
ipfs mount
cd /ipfs/<the-hash-here>
ls
Tool: //工具
ipfs version
ipfs update
ipfs commands
ipfs config --help

注意此时终端的命令没有结束，也就是说目前的启动是不能关闭终端的
此时访问之前的图片网址http://localhost:8080/ipfs/QmZpc3HvfjEXvLWGQPWbHk3AjD5j8NEN4gmFN8Jmrd5g83/cs,展示效果如下，文件访问成功。
同理，访问视频文件和markdown文件也能正常访问。
在demo中给的webui实际上是一个管理后台，可以查看这个项目被放到了全球多少个节点上。
出现的报错
ERROR core/serve: ipfs resolve -r /ipfs/QmPhnvn747LqwPYMJmQVorMaGbMSgA7mRRoyyZYz3DoZRQ/locale/webui-zh.json: no link named "webui-zh.json" under Qmc6bAsXTFFdvV3RoLuf6jjV3jzsRLntfsivWQZ75s8QaL gateway_handler.go:584ERROR flatfs: too many open files, retrying in 100ms flatfs.go:180ERROR mdns: mdns lookup error: failed to bind to any unicast udp port mdns.go:135
总结
- 了解了IPFS的安装
- 本机成功启动了demo
- 遇到了一些小问题
