一、安装

可以使用 Manjaro 系统自带的包管理命令安装

sudo pacman -S go-ipfs

其他 Linux 系统可以用自带的包管理命令搜索ipfs关键字查找包再安装，如果不行就直接下载程序安装，安装可以参考 ipfs 的 github 仓库 https://github.com/ipfs/go-ipfs
如果系统有安装 Docker，也可以使用 ipfs 的 Docker 镜像 https://hub.docker.com/r/ipfs/go-ipfs

docker pull ipfs/go-ipfs

二、启动

ipfs 节点初始化

ipfs init

执行此命令使用默认配置初始化节点，将在家目录 (用户目录) 生成一个.ipfs 的文件夹存储节点数据，其中 config 文件是节点的配置，可以修改。
再使用 daemon 命令启动

ipfs daemon

会启动默认的 WEBUI 为 http://127.0.0.1:5001/webui ，浏览器打开此链接可以查看本地 ipfs 节点的状态

Docker 容器启动命令参考，可以使用-v选项挂载两个目录：

1. /data/ipfs，ipfs 存储数据的目录，挂载后容器销毁时可以保留 ipfs 数据

2. /export，ipfs 导出目录，容器不能访问主机的文件，挂载后可以通过此目录导入导出文件

   docker run -d --name ipfs_host -v /root/ipfs/export:/export -v /root/ipfs/data:/data/ipfs -p 4001:4001 -p 8080:8080 -p 5001:5001 ipfs/go-ipfs

三、公开节点

默认启动是本地节点，如果是其他电脑要访问，需要配置跨域和绑定 ip 地址

ipfs config --json API.HTTPHeaders.Access-Control-Allow-Methods '["PUT","GET", "POST", "OPTIONS"]'
ipfs config --json API.HTTPHeaders.Access-Control-Allow-Origin '["*"]'
ipfs config --json API.HTTPHeaders.Access-Control-Allow-Credentials '["true"]'
ipfs config --json API.HTTPHeaders.Access-Control-Allow-Headers '["Authorization"]'
ipfs config --json API.HTTPHeaders.Access-Control-Expose-Headers '["Location"]'
ipfs config --json Addresses.API '"/ip4/0.0.0.0/tcp/5001"'
ipfs config --json Addresses.Gateway '"/ip4/0.0.0.0/tcp/8080"'

docker 容器启动的 ipfs 需要使用docker exec <容器>来执行 ipfs 命令

docker exec ipfs_host ipfs config --json API.HTTPHeaders.Access-Control-Allow-Methods '["PUT","GET", "POST", "OPTIONS"]'
docker exec ipfs_host ipfs config --json API.HTTPHeaders.Access-Control-Allow-Origin '["*"]'
docker exec ipfs_host ipfs config --json API.HTTPHeaders.Access-Control-Allow-Credentials '["true"]'
docker exec ipfs_host ipfs config --json API.HTTPHeaders.Access-Control-Allow-Headers '["Authorization"]'
docker exec ipfs_host ipfs config --json API.HTTPHeaders.Access-Control-Expose-Headers '["Location"]'
docker exec ipfs_host ipfs config --json Addresses.API '"/ip4/0.0.0.0/tcp/5001"'
docker exec ipfs_host ipfs config --json Addresses.Gateway '"/ip4/0.0.0.0/tcp/8080"'

ip 和端口可以按需配置，也可以直接去修改配置文件$HOME/.ipfs/config

...
  "API": {
    "HTTPHeaders": {
      "Access-Control-Allow-Credentials": [
        "true"
      ],
      "Access-Control-Allow-Headers": [
        "Authorization"
      ],
      "Access-Control-Allow-Methods": [
        "PUT",
        "GET",
        "POST",
        "OPTIONS"
      ],
      "Access-Control-Allow-Origin": [
        "*"
      ],
      "Access-Control-Expose-Headers": [
        "Location"
      ]
    }
  },
  "Addresses": {
    "API": "/ip4/0.0.0.0/tcp/5001",
    "Announce": [],
    "Gateway": "/ip4/0.0.0.0/tcp/8080",
    "NoAnnounce": [],
    "Swarm": [
      "/ip4/0.0.0.0/tcp/4001",
      "/ip6/::/tcp/4001",
      "/ip4/0.0.0.0/udp/4001/quic",
      "/ip6/::/udp/4001/quic"
    ]
  },
...

四、帮助手册

ipfs 命令自带使用手册，在终端执行ipfs命令即可，子命令的帮助需要添加选项-h，例如ipfs init -h

  ipfs uses a repository in the local file system. 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
