背景：听说IPFS=bittorrent+bitcoin+git+afs，有可能取代http，好像厉害的不行，所以要研究一下。
编译参考：https://github.com/ipfs/go-ipfs 结果各种墙都翻好了，一切基础设施都到位了，还是没编译成功shit(最后还是编过了)。
退而求其次，直接用官方提供的先试验一下吧。
下载地址：https://ipfs.io/docs/install/
1.上传安装
下载相应的版本，我下载的是：go-ipfs_v0.4.14_linux-amd64.tar.gz，上传到服务器，解压。
someone@ipfs:~$ tar -zxvf go-ipfs_v0.4.14_linux-amd64.tar.gz someone@ipfs:~$ cd go-ipfs/ someone@ipfs:~$ ./install.sh someone@ipfs:~/package/go-ipfs$ ipfs
显示的结果如下:
USAGE ipfs - Global p2p merkle-dag filesystem. ipfs [--config=<config> | -c] [--debug=<debug> | -D] [--help=<help>] [-h=<h>] [--local=<local> | -L] [--api=<api>] <command> ...

By default, the repo is located at ~/.ipfs. To change the repo location, set the $IPFS_PATH environment variable: export IPFS_PATH=/path/to/ipfsrepo EXIT STATUS The CLI will exit with one of the following values: 0 Successful execution. 1 Failed executions.
2. 初始化
someone@ipfs:~$ mkdir -p /ipfs/ /*很明显，根本不用执行这个命令，下面的/ipfs也不是指本地文件系统的/ipfs.*/ someone@ipfs:~$ ipfs init initializing IPFS node at /home/someone/.ipfs generating 2048-bit RSA keypair...done peer identity: QmSuUJKAfxYamzekBT2ePfyypyTXP3DgEsGKPxiedUneGh to get started, enter: ipfs cat /ipfs/QmS4ustL54uo8FzR9455qaxZwuMiUhyvMcX9Ba8nUH4uVv/readme someone@ipfs:~/.ipfs$ ipfs cat /ipfs/QmS4ustL54uo8FzR9455qaxZwuMiUhyvMcX9Ba8nUH4uVv/readme
显示结果如下：
#这条命令只是查看行不行，其实没有别的作用 Hello and Welcome to IPFS! ██╗██████╗ ███████╗███████╗ ██║██╔══██╗██╔════╝██╔════╝ ██║██████╔╝█████╗ ███████╗ ██║██╔═══╝ ██╔══╝ ╚════██║ ██║██║ ██║ ███████║ ╚═╝╚═╝ ╚═╝ ╚══════╝ If you're seeing this, you have successfully installed IPFS and are now interfacing with the ipfs merkledag! ------------------------------------------------------- | Warning: | | This is alpha software.

至此，所有的ipfs的内容都在 ~/.ipfs目录下了
someone@ipfs:~/.ipfs$ ls api blocks config datastore datastore_spec keystore repo.lock version
3. 修改配置文件
可以使用如下命令
someone@ipfs:export EDITOR=/usr/bin/vim someone@ipfs:ipfs config edit
查看节点ID
someone@ipfs:~$ ipfs id
{
"ID": "QmSuUJKAfxYamzekBT2ePfyypyTXP3DgEsGKPxiedUneGh",
"PublicKey": "CAASpgIwggEiMA0GCSqGSIb3DQEBAQUAA4IBDwAwggEKAoIBAQDBTEUgY8FCDbZeV8+h1XdRivlUVRlVlNmwr0oFP1ceoBnbMXP5IJ9GSXXLVVwl4IPwFBEscMo1wo6NRz3oMDeQWEgi9x5wuEOYvlNUAzVbwFWb77AmW10oZpGz7oo45Fd37/jdU+6JcDKPc4o5sR9pJo8PddP3g7rphF7nHncf3vh4vNeCsu0DylxPh6CGHf6+8c50Vjl9iAwBZ9zES+QYT4kYHF3icX63p2B8B5C+7ZC9ISfD4ZiKTYBHDob/XLQc7g7gdEbGuxmXJE/iFzju2PoEe+Ob1QXCAabWq80F/oxCAdX+wLisgHE6FbeYp5RV7IRi7s3L3xpFnQPukswtAgMBAAE=",
"Addresses": null,
"AgentVersion": "go-ipfs/0.4.14/",
"ProtocolVersion": "ipfs/0.1.0"
}
跨域资源共享CORS配置
someone@ipfs:~$ ipfs config --json API.HTTPHeaders.Access-Control-Allow-Methods '["PUT", "GET", "POST", "OPTIONS"]' someone@ipfs:~$ ipfs config --json API.HTTPHeaders.Access-Control-Allow-Origin '["*"]'
4. 启动服务器
someone@ipfs:~/.ipfs$ ipfs daemon Initializing daemon... Successfully raised file descriptor limit to 2048. Swarm listening on /ip4/127.0.0.1/tcp/4001 Swarm listening on /ip4/192.168.15.129/tcp/4001 Swarm listening on /ip6/::1/tcp/4001 Swarm listening on /p2p-circuit/ipfs/QmSuUJKAfxYamzekBT2ePfyypyTXP3DgEsGKPxiedUneGh Swarm announcing /ip4/127.0.0.1/tcp/4001 Swarm announcing /ip4/192.168.15.129/tcp/4001 Swarm announcing /ip6/::1/tcp/4001 API server listening on /ip4/127.0.0.1/tcp/5001 Gateway (readonly) server listening on /ip4/127.0.0.1/tcp/8080 Daemon is ready
启动成功后就可以，查看UI界面了:
http://127.0.0.1:5001/webui
结果如下：
5. 编译失败后调试成功
按步骤编译，墙也是翻好的，每次都卡在类似的地方：
someone@ipfs:~$ make install .... [get ] [fetch] go-libp2p-crypto QmaPbCnUMBohSGo3KnxEa2bHqyJVVeEEcwtqJAYxerieBo [0 / 202] 392sERROR: [2 / 101 ] parallel fetch: failed to fetch package: QmRb5jh8z2E8hMGN2tkvs1yHynUanqnZ3UeKwgN1i9P1F8: Post https://ipfs.io/api/v0/get?arg=QmRb5jh8z2E8hMGN2txxxx1yHynUanqnZ3UeKwgN1i9P1F8&encoding=json&stream-channels=true: dial tcp 173.252.100.32:443: getsockopt: connection timed out [0 / 202] 442s^Cmk/gx.mk:4: recipe for target 'gx-deps' failed
https再开一个终端，wget都可以访问。使用"make install_unsupported"也没卵用，然后再次"make install"还是不行。
结果，第二天，安装完官方的ipfs并启动后，再make install 源码，结果，编译通过了，难道这个编译是看天气的吗？
猜测编译可能和以下操作有关：
apt-get install libzip-dev
