- 安装好 go 环境
- 安装好 docker
swarm.key
swarm.key 用来做私链认证的密钥，最终要放在 /ipfs/data 目录下
go get github.com/Kubuxu/go-ipfs-swarm-key-gencd $GOPATHgo build./ipfs-swarm-key-gen > swarm.key
查下生成的 swarm.key 内容：
/key/swarm/psk/1.0.0/
/base16/

挂载目录
ipfs 的 export 和 data 目录挂载到主机上，这里做下准备，每个不同是私链节点的挂载目录不一样。
节点 node0 要挂载的主机目录：
/Users/lidiqing/Docker/ipfs/nodes/node0/export/Users/lidiqing/Docker/ipfs/nodes/node0/data
节点 node1 要挂载的主机目录：
/Users/lidiqing/Docker/ipfs/nodes/node1/export/Users/lidiqing/Docker/ipfs/nodes/node1/data

启动容器
创建节点
这里演示创建节点 node0 的流程，其他节点的创建流程一致，端口号和目录要修改。
把 swarm.key 放入到 /Users/lidiqing/Docker/ipfs/nodes/node0/data 目录下。
启动：
docker run
--name ipfs-node-0
-v /Users/lidiqing/Docker/ipfs/nodes/node001/export:/export
-v /Users/lidiqing/Docker/ipfs/nodes/node001/data:/data/ipfs
-p 10000:4001
-p 11000:5001
-p 12000:8080
-d ipfs/go-ipfs:latest
查看日志:
docker logs -f ipfs-node-0
stevenpc:~ lidiqing$ docker logs ipfs-node-0

Daemon is ready
打印出 Daemon is ready 说明 ipfs 已经启动了。Swarm is limited to private network of peers with the swarm key 可以看出使用了密钥，属于私链节点。
需要清理一下公链的引导节点。
docker exec ipfs-node-0 bootstrap rm —all
查看节点
按照上面的方式我们创建了多个节点，现在进入 node0 查看下情况。
打开节点的 shell：
docker exec -it ipfs-node-0 /bin/sh
查看已连接的所有 p2p 节点：
