StudyRecord-IPFS使用入门

安装：

下载链接

Linux 平台下，使用以下命令进行安装：

tar xvfz kubo_v0.17.0_linux-amd64.tar.gz
cd kubo
./install.sh

初始化:

安装完成之后，要使用IPFS第一步是要对IPFS进行初始化

[root@localhost kubo]# ipfs init
generating ED25519 keypair...done
peer identity: 12D3KooWCmmHYHQSZ2woV7euLdFenHDj1g6PtmkQpzTJYGtZM9mo
initializing IPFS node at /root/.ipfs
to get started, enter:

        ipfs cat /ipfs/QmQPeNsJPyVWPFDVHb77w8G42Fvo15z4bG2X8D2GhfbSXc/readme

配置修改:

修改配置文件:

vim ~/.ipfs/config

# 修改为内网IP
"Addresses": {
    "API": "/ip4/192.168.2.23/tcp/5001",
    "Announce": [],
    "AppendAnnounce": [],
    "Gateway": "/ip4/192.168.2.23/tcp/8080",

允许跨域:

[root@localhost ~]# ipfs config --json API.HTTPHeaders.Access-Control-Allow-Origin '["http://192.168.2.23:5001", "http://localhost:3000", "http://127.0.0.1:5001", "https://webui.ipfs.io"]'
[root@localhost ~]# ipfs config --json API.HTTPHeaders.Access-Control-Allow-Methods '["PUT", "POST"]'

上传文件:

> echo "HelloWorld" >> upchain.pro.txt

ipfs 使用add 命令来添加内容到节点中，

[root@localhost ~]# ipfs add upchain.pro.txt
added QmfJs3ZYScPctKNfbYDYbkHX6akxgshtn6cPSEj9prqdQz upchain.pro.txt
11 B / 11 B [==============================================================================================================================] 100.00%

当它文件添加到节点时，会为文件生成唯一的hash:QmfJs3ZYScPctKNfbYDYbkHX6akxgshtn6cPSEj9prqdQz, 可以使用ipfs cat查看文件的内容：

[root@localhost ~]# ipfs cat QmfJs3ZYScPctKNfbYDYbkHX6akxgshtn6cPSEj9prqdQz
HelloWorld

开启服务:

此时文件仅仅是上传在本地的IPFS节点中，如果需要把文件同步到网络，就需要开启 daemon 服务， 使用命令：

[root@localhost ~]# ipfs daemon
