IPFS 搭建

官网

https://ipfs.io 可能需要梯子

下载和编译

下载代码

git clone https://github.com/ipfs/go-ipfs.git
首先需要 1.16版本以上的go环境
下载go

安装go

ubuntu@ubuntu-sol:~/IPFS$wget https://golang.org/dl/go1.17.2.linux-amd64.tar.gz
ubuntu@ubuntu-sol:~/IPFS$tar -zxvf go1.17.2.linux-amd64.tar.gz
ubuntu@ubuntu-sol:~/IPFS$sudo mv go /usr/local
ubuntu@ubuntu-sol:~/IPFS$vi ~/.profile
在末尾输入 export PATH=$PATH:/usr/local/go/bin
ubuntu@ubuntu-sol:~/IPFS$source ~/.profile
ubuntu@ubuntu-sol:~/IPFS$ go version
go version go1.17.2 linux/amd64

源码

找一个目录，下载源码

ubuntu@ubuntu-sol:~/IPFS$ mkdir ipfs && cd ipfs
ubuntu@ubuntu-sol:~/IPFS/ipfs$ git clone https://github.com/ipfs/go-ipfs.git
ubuntu@ubuntu-sol:~/IPFS/ipfs$ cd go-ipfs
## 选择需要的版本
ubuntu@ubuntu-sol:~/IPFS/ipfs/go-ipfs$ git checkout v0.10.0

编译IPFS

编译安装比较久，可以使用下面的官方直接下载release好的ipfs进行安装

ubuntu@ubuntu-sol:~/IPFS/ipfs/go-ipfs$ make build
ubuntu@ubuntu-sol:~/IPFS/ipfs/go-ipfs$ make install

官方release的ipfs

可以通过下面的链接直接下载官方编译好的ipfs
https://github.com/ipfs/go-ipfs/releases
文档采用的是下面这个地址
https://github.com/ipfs/go-ipfs/releases/download/v0.10.0/go-ipfs_v0.10.0_linux-amd64.tar.gz
压缩包里面的和源码 go-ipfs/cmd/ipfs/dist目录下内容是一样的，只是没有ipfs 文件，源码编译后，会在ipfs目录下生成ipfs文件

ubuntu@ubuntu-sol:~/IPFS/ipfs$ tar -zxf go-ipfs_v0.10.0_linux-amd64.tar.gz
ubuntu@ubuntu-sol:~/IPFS/ipfs$ cd go-ipfs
ubuntu@ubuntu-sol:~/IPFS/ipfs/go-ipfs$ ls
install.sh  ipfs  LICENSE  LICENSE-APACHE  LICENSE-MIT  README.md
ubuntu@ubuntu-sol:~/IPFS/ipfs/go-ipfs$ sudo ./install.sh 
Moved ./ipfs to /usr/local/bin

测试

输入ipfs help 测试安装成功

ubuntu@ubuntu-sol:~/IPFS/ipfs/go-ipfs$ ipfs --version
ipfs version 0.10.0
ubuntu@ubuntu-sol:~/IPFS/ipfs/go-ipfs$ ipfs help
USAGE
  ipfs  - Global p2p merkle-dag filesystem.

SYNOPSIS
  ipfs [--config=<config> | -c] [--debug | -D] [--help] [-h] [--api=<api>] [--offline] [--cid-base=<base>] [--upgrade-cidv0-in-output] [--encoding=<encoding> | --enc] [--timeout=<timeout>] <command> ...

OPTIONS

  -c, --config               string - Path to the configuration file to use.
  -D, --debug                bool   - Operate in debug mode.
  --help                     bool   - Show the full command help text.
  -h                         bool   - Show a short version of the command help text.
  -L, --local                bool   - Run the command locally, instead of using the daemon. DEPRECATED: use --offline.
  --offline                  bool   - Run the command offline.
  --api                      string - Use a specific API instance (defaults to /ip4/127.0.0.1/tcp/5001).

示例

直接使用ipfs 上传文件

ubuntu@ubuntu-sol:~/test$ ipfs add test3
added QmTZpQW6Vq65LTHUuJUbrNHmFdgGwP1spTvLRZkQwGmdj9 test3
 15 B / 15 B [======================] 100.00%

使用ipfs 上传目录

ubuntu@ubuntu-sol:~/test$ ipfs add -r testdir
added QmSwLYeFSWzifHNypYrkfx39zPXTpGNDLD5WdmLS8hWLot testdir/test2
added QmTZpQW6Vq65LTHUuJUbrNHmFdgGwP1spTvLRZkQwGmdj9 testdir/test3
added QmTqoHrSQuJXdJ4cFgVpv59P1yVjpjcajDqUeWDVSaiaxb testdir
 21 B / 21 B [======================] 100.00%

使用HTTP API 上传文件

curl example

curl -X POST -F file=@myfile "http://127.0.0.1:5001/api/v0/add?quiet=<value>&quieter=<value>&silent=<value>&progress=<value>&trickle=<value>&only-hash=<value>&wrap-with-directory=<value>&chunker=size-262144&pin=true&raw-leaves=<value>&nocopy=<value>&fscache=<value>&cid-version=<value>&hash=sha2-256&inline=<value>&inline-limit=32"

上面<value> 是参数的值，需要修改，除了cid-version 是int类型，其他都是bool类型（可以用true/false 或者0/1），参数根据需要使用

参数说明可以参考 IPFS HTTP API http-commands

注意file=@myfile这个@，没有这个@上传的就成了文件名，而不是文件的内容了

下面是上传一个文件名为 tstst 的测试文件的例子

默认情况下可以不加参数

ubuntu@ubuntu-sol:~/test/heihei$ curl -X POST -F file=@tstst "http://127.0.0.1:5001/api/v0/add"
{"Name":"tstst","Hash":"QmfUJdALjZxhsiyBLyccj9sZFpygAEhk5UUfLVCi45rZND","Size":"34"}
ubuntu@ubuntu-sol:~/test/heihei$ ipfs cat /ipfs/QmfUJdALjZxhsiyBLyccj9sZFpygAEhk5UUfLVCi45rZND
This is a ipfs test file.

如上所示，上传成功后可看到文件的Hash值，可以通过这个Hash 去webui查看上传的文件是不是正确的

也可以通过webui上传文件
查看文件的cid为QmVP7TY79k7ozPna5vPnxUANS68kpPdcLs4s7XTtdzN7Vn
通过ipfs的命令获取文件

ipfs cat /ipfs/QmVP7TY79k7ozPna5vPnxUANS68kpPdcLs4s7XTtdzN7Vn > tu.jpg

因为这里上传的是一个图片，直接获取看不到，所以重定向到一个jpg文件查看

使用IPNS

在IPFS中，对一个文件的内容修改后（如升级），会生成一个完全不同的新Hash，使用IPNS就可以利用同一个链接总是指向更新的内容，其实使用也很简单，只需要每次在内容更新之后使用ipfs name publish hash 发布到节点。

ubuntu@ubuntu-sol:~/test$ ipfs name publish QmTZpQW6Vq65LTHUuJUbrNHmFdgGwP1spTvLRZkQwGmdj9
Published to k51qzi5uqu5dlaeb0xwy5kx53q8ofyj036rhn8n529n1js070983cdgu8y3kw5: /ipfs/QmTZpQW6Vq65LTHUuJU$ ipfs name publish QmSwLYeFSWzifHNypYrkfx39zPXTpGNDLD5WdmLS8hWLot
Published to k51qzi5uqu5dlaeb0xwy5kx53q8ofyj036rhn8n529n1js070983cdgu8y3kw5: /ipfs/QmSwLYeFSWzifHNypYrkfx39zPXTpGNDLD5WdmLS8hWLot

这里 QmTZpQW6Vq65LTHUuJUbrNHmFdgGwP1spTvLRZkQwGmdj9 是test3文件的hash，QmSwLYeFSWzifHNypYrkfx39zPXTpGNDLD5WdmLS8hWLot 是test2文件的hash，两次publish后可以看到得到的是相同的地址，k51qzi5uqu5dlaeb0xwy5kx53q8ofyj036rhn8n529n1js070983cdgu8y3kw5，前后两次访问相同的地址http://192.168.0.17:8080/ipns/k51qzi5uqu5dlaeb0xwy5kx53q8ofyj036rhn8n529n1js070983cdgu8y3kw5 得到的内容分别是test3和test2的内容

也可以通过当前节点ID来访问，就是 ipfs init 命令后生成的 peer identity，通过ipfs id可以查看当前节点ID http://192.168.0.17:8080/ipns/12D3KooWPc2pTzK4VtPnoN8x9dTdGUvUSzVkRX9U7gX6sg7Szoh6 的结果和上面http://192.168.0.17:8080/ipns/k51qzi5uqu5dlaeb0xwy5kx53q8ofyj036rhn8n529n1js070983cdgu8y3kw5的结果是一样的

查看目前链接所指向的文件

ubuntu@ubuntu-sol:~/test$ ipfs name resolve
/ipfs/QmSwLYeFSWzifHNypYrkfx39zPXTpGNDLD5WdmLS8hWLot

如果有多个文件需要使用IPNS，可以新建一key，将不同的文件 publish 到不同的key 上去，上面的k51qzi5uqu5dlaeb0xwy5kx53q8ofyj036rhn8n529n1js070983cdgu8y3kw5其实就是系统生成的默认的key，

# 生成key
ubuntu@ubuntu-sol:~/test/$ ipfs key gen --type=rsa --size=2048 mykey
k2k4r8o5eus56y2m378zzjhuwu6x5rb2p0rv0bg6slb3nt9spzreg6u8
# 使用生成的key publish QmTZpQW6Vq65LTHUuJUbrNHmFdgGwP1spTvLRZkQwGmdj9
ubuntu@ubuntu-sol:~/test$ ipfs name publish -key=mykey QmTZpQW6Vq65LTHUuJUbrNHmFdgGwP1spTvLRZkQwGmdj9
Published to k2k4r8o5eus56y2m378zzjhuwu6x5rb2p0rv0bg6slb3nt9spzreg6u8: /ipfs/QmTZpQW6Vq65LTHUuJUbrNHmFdgGwP1spTvLRZkQwGmdj9
# 使用ipfs name resolve 看到的还是默认的
ubuntu@ubuntu-sol:~/test/heihei$ ipfs name resolve
/ipfs/QmSwLYeFSWzifHNypYrkfx39zPXTpGNDLD5WdmLS8hWLot
# 使用 ipfs name resolve 加 key 可以看到该 key 对应的文件
ubuntu@ubuntu-sol:~/test/heihei$ ipfs name resolve k2k4r8o5eus56y2m378zzjhuwu6x5rb2p0rv0bg6slb3nt9spzreg6u8
/ipfs/QmTZpQW6Vq65LTHUuJUbrNHmFdgGwP1spTvLRZkQwGmdj9
