centos7 下使用docker 搭建ipfs 集群

简介

IPFS是一个对等的分布式文件系统，它尝试为所有计算设备(ipfs矿机)连接同一个文件系统。在某些方面，IPFS类似于万维网，但它也可以被视作一个独立的BitTorrent群、在同一个Git仓库中交换对象。换种说法，IPFS提供了一个高吞吐量、按内容寻址的块存储模型，及与内容相关超链接。这形成了一个广义的Merkle有向无环图（DAG）。IPFS结合了分布式散列表、鼓励块交换和一个自我认证的命名空间。IPFS没有单点故障，并且节点不需要相互信任。分布式内容传递可以节约带宽，和防止HTTP方案可能遇到的DDoS攻击。
在这里插入图片描述

IPFS
该文件系统可以通过多种方式访问，包括FUSE与HTTP。将本地文件添加到IPFS文件系统可使其面向全世界可用。文件表示基于其哈希，因此有利于缓存。文件的分发采用一个基于BitTorrent的协议。其他查看内容的用户也有助于将内容提供给网络上的其他人。IPFS有一个称为IPNS的名称服务，它是一个基于PKI的全局命名空间，用于构筑信任链，这与其他NS兼容，并可以映射DNS、.onion、.bit等到IPNS。

1.0 实验环境

前置环境
1.docker容器环境
2.docker-compose
需要提前安装可以参考容器化部署脚本.
3.实验环境会用到三台主机自行搭建

1.1 新建docker-compose 启动目录

[root@localhost ~]# mkdir -p /data/ipfs
[root@localhost ~]# cd /data/ipfs
#新建容器挂载目录
[root@localhost ipfs]# mkdir data
[root@localhost ipfs]# mkdir staging
[root@localhost ipfs]# cat docker-compose.yaml 
version: '3'
services:
 ipfs:
    image: ipfs/go-ipfs:latest
    container_name: ipfs
    restart: always
    volumes:
      - ./staging:/export
      - ./data:/data/ipfs
    ports:
      - 4001:4001
      - 0.0.0.0:10053:5001
      - 0.0.0.0:10052:8080
    entrypoint: /sbin/tini -- /usr/local/bin/start_ipfs daemon --migrate=true --enable-gc

[root@localhost ipfs]# docker-compose up -d
Creating network "ipfs_default" with the default driver
Creating ipfs ... done

镜像没有他自己会去下载三台主机依次操作

1.2 查看容器id

[root@localhost ipfs]# docker exec -it ipfs sh 
#进入容器后执行
#/ ipfs repo gc
#清理无用的repo
/ # ipfs id

1.3 节点同步

建议第二种，会有返回，节点之间互通，需要在每个节点添加另外两个节点id,告诉他另外两个节点的地址，node1 节点添加节点的时候，只需要添加另外两个节点的id,ip4的地址也需要替换为节点的ip,而不是他的默认节点ip,另外两个节点同样操作

第一种
#/ipfs bootstrap add /ip4/127.0.0.1/tcp/4001/p2p/12D3KooWCBy35BSF18cqecMvuZdkrDscj1HqFstmJA3Ns5nrWyXc
第二种
#/ipfs swarm connect /ip4/127.0.0.1/tcp/4001/p2p/12D3KooWCBy35BSF18cqecMvuZdkrDscj1HqFstmJA3Ns5nrWyXc

1.4 验证

#在node1 节点操作
/ # echo "123123" > wang
/ # ipfs add wang
added QmQsBgc4fzWXhSCEwQUQRjPGtZUM9ePjuYehy9pxYesCpQ wang
 7 B / ? [-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------=------] 
 
# QmQsBgc4fzWXhSCEwQUQRjPGtZUM9ePjuYehy9pxYesCpQ
# 这个就是我们创建文件在这个集群里的唯一哈希
# 在其他节点验证

/ # ipfs cat QmQsBgc4fzWXhSCEwQUQRjPGtZUM9ePjuYehy9pxYesCpQ
123123

集群搭建完成，欢迎补充
