什么是IPFS?
ipfs: 是一个类似于 百度网盘一样的东西， 大家都可以上传文件。 全世界有好多个节点（例如100W个）。 东西存放在哪里，并不清楚，只要知道我们可以随时使用就可以了
https://cloudflare-ipfs.com/ipfs/
上面的网址，是一个专门查看IPFS资料的入口。
使用方式：
https://cloudflare-ipfs.com/ipfs/bafybeigsn4u4nv4uyskxhewakk5m2j2lluzhsbsayp76zh7nbqznrxwm7e/
入口 + ipfs_cid 方式，就可以查看了。例如：
安装 ipfs cluster
1. cd /opt/app
wget https://dist.ipfs.tech/ipfs-cluster-ctl/v1.0.2/ipfs-cluster-ctl_v1.0.2_linux-amd64.tar.gz
2. tar zxvf ipfs-cluster-ctl_v1.0.2_linux-amd64.tar.gz
ipfs-cluster-ctl/LICENSE ipfs-cluster-ctl/LICENSE-APACHE ipfs-cluster-ctl/LICENSE-MIT ipfs-cluster-ctl/README.md ipfs-cluster-ctl/ipfs-cluster-ctl
3. cd /opt/app/ipfs-cluster-ctl
wget https://raw.githubusercontent.com/ipfs/ipfs-cluster/v1.0.2/docker-compose.yml
建议跳过上面的wget方式，直接使用这个现成的yml:
version: '3.4'
services:
ipfs0:
container_name: ipfs0
image: ipfs/go-ipfs:latest
ports:
- "4001:4001" # ipfs swarm - expose if needed/wanted
- "5001:5001" # ipfs api - expose if needed/wanted
- "8080:8080" # ipfs gateway - expose if needed/wanted
volumes:
- ./compose/ipfs0:/data/ipfs
cluster0:
container_name: cluster0
image: ipfs/ipfs-cluster:latest
depends_on:
- ipfs0
environment:
CLUSTER_PEERNAME: cluster0
CLUSTER_SECRET: ${CLUSTER_SECRET} # From shell variable if set
CLUSTER_IPFSHTTP_NODEMULTIADDRESS: /dns4/ipfs0/tcp/5001
CLUSTER_CRDT_TRUSTEDPEERS: '*' # Trust all peers in Cluster
CLUSTER_RESTAPI_HTTPLISTENMULTIADDRESS: /ip4/0.0.0.0/tcp/9094 # Expose API
CLUSTER_MONITORPINGINTERVAL: 2s # Speed up peer discovery
ports:
# Open API port (allows ipfs-cluster-ctl usage on host)
- "127.0.0.1:9094:9094"
# The cluster swarm port would need to be exposed if this container
# was to connect to cluster peers on other hosts.
# But this is just a testing cluster.
# - "9095:9095" # Cluster IPFS Proxy endpoint
# - "9096:9096" # Cluster swarm endpoint
volumes:
- ./compose/cluster0:/data/ipfs-cluster
4. sudo docker-compose up
首次运行会报错，或者直接 docker-compose的output会退出（此时docker ps 还是能看到进程还在的）
不要紧。
sudo docker-compose down 之后，再 up 一下，就可以看到了：
cluster0 | 2022-09-03T09:58:53.726Z INFO crdt [email protected]/set.go:122 Tombstones have bloomed: 0 tombs.

5. 测试一下：

添加一个文件：

看一下docker ps :

根据 docker log, 我们可以知道，有 ipfs cluster 运行在了docker 的 5001端口，该docker app映射到了 host 的9094, 9095, 9096端口。
所以我们访问：curl localhost:9094/webui
{"code":404,"message":"not found"}
就说明它一定是运行好了。
安装ipfs cli
wget https://dist.ipfs.tech/kubo/v0.15.0/kubo_v0.15.0_linux-amd64.tar.gz
tar zxvf kubo_v0.15.0_linux-amd64.tar.gz kubo/
cd kubo/
sudo bash install.sh
ipfs gateway
gateway会自动的跑起来。跑在本地的8080端口
ipfs init

然后就可以在浏览器中查看了：
ipfs 文件的类型：
如何根据CID查看IPFS的文件夹结构：
curl -s "https://ipfsgate.test-ddns.com/api/v0/ls?arg=bafybeigsn4u4nv4uyskxhewakk5m2j2lluzhsbsayp76zh7nbqznrxwm7e"
或者：
curl -s "https://ipfsgate.test-ddns.com/api/v0/ls?arg=QmbKu58pyq3WRgWNDv9Zat39QzB7jpzgZ2iSzaXjwas4MB"
得到结果：
