2 安装ipfs
具体安装过程可以参照如下链接：https://ipfs.io/docs/install/
2.1 下载
下载地址：https://dist.ipfs.io/#go-ipfs
下载：go-ipfs_v0.4.16_linux-amd64.tar.gz
2.2 安装
$ tar zxvf go-ipfs_v0.4.16_linux-amd64.tar.gz
$ cd go-ipfs
$ ./install.sh
安装成功后会将go-ipfs文件夹下的ipfs文件移动到/usr/local/bin目录下
2.3 测试
运行ipfs help命令，如果出现如下内容说明安装成功。
$ ipfs help
USAGE
ipfs - Global p2p merkle-dag filesystem.
ipfs [--config=<config> | -c] [--debug=<debug> | -D] [--help=<help>] [-h=<h>] [--local=<local> | -L] [--api=<api>] <command> ...
3 节点配置
3.1 创建节点
执行命令ipfs init
$ ipfs init
initializing IPFS node at /home/fc/.ipfs
generating 2048-bit RSA keypair...done
peer identity: QmYptDAwzpZQunynPi5oUQBCyXYJRCVphaPLuL1BPhpZVh
to get started, enter:
ipfs cat /ipfs/QmS4ustL54uo8FzR9455qaxZwuMiUhyvMcX9Ba8nUH4uVv/readme
执行以上命令后，或者用户的根目录（ /home/fc/）下生成一个名为.ipfs文件夹用于存储节点数据。
3.2 修改存储空间
.ipfs节点的默认存储空气为10个Ｇ，如果需要修改可以在~/.ipfs/config文件中修改。
将"StorageMax": "10GB"修改为其他值即可。
3.3 查看节点ID
使用命令ipfs id
$ ipfs id
{
"ID": "QmYptDAwzpZQunynPi5oUQBCyXYJRCVphaPLuL1BPhpZVh",
"PublicKey": "CAASpgIwggEiMA0GCSqGSIb3DQEBAQUAA4IBDwAwggEKAoIBAQDtDhxfTIZwnHR25wobaGoEjYkub/oAH57nwPpVhg/dLhDXn3zpG1Gd773S2N6bWZzqnilSzVyVbPHP6WVxgtLZK/iQ4uWcipn7mzACyx9qkJown13H8DqLHrzdMkRc//MyylsUI8FSWWzmd3O/yMliupjPIQIV+b8sfBOSpoBuWJu4RBh8HcHV91iQpNxua4R0uU4uaUtQxVvLjwhu3lKWEuZBhk6Q42WFPF99QWTVWYMD05mVNs2cDJ2kZOjbFUW4803JeCGTPEtHz9KSZI3EGefynIUqNEU0nxXxS/E13OdM8rDyQqQ4tBFKN5WAFxkjGK13UryNu6O7RJ0nLRFPAgMBAAE=",
"Addresses": null,
"AgentVersion": "go-ipfs/0.4.16/",
"ProtocolVersion": "ipfs/0.1.0"
}
3.4 添加文件到节点
- 添加命令：ipfs add filename
- 查看命令：ipfs cat 添加文件时返回的哈希值
具体操作：
创建一个文件并在里面写入"123456"：
$ touch ipfsfile.txt
$ echo "123456" > ipfsfile.txt
添加到本地节点：
$ ipfs add ipfsfile.txt
added QmQU2gS4gZ7TpiTECjDUxdQFd9bBBEWxDxPPfhLfYHVuei ipfsfile.txt
7 B / 7 B [===============================================================================================] 100.00%
添加成功后，会返回该文件的哈希QmQU2gS4gZ7TpiTECjDUxdQFd9bBBEWxDxPPfhLfYHVuei，我们可以通过它来查看刚刚添加的文件:
$ ipfs cat QmQU2gS4gZ7TpiTECjDUxdQFd9bBBEWxDxPPfhLfYHVuei
123456
3.5 启动节点服务器
使用命令ipfs daemon
$ ipfs daemon
Initializing daemon...
