  Use 'ipfs <command> --help' to learn more about each command.ipfs uses a repository inthelocalfilesystem. By default, therepo islocated at~/.ipfs. To change therepo location, setthe$IPFS_PATH
  environment variable:

    export IPFS_PATH=/path/to/ipfsrepo

  EXIT STATUS

  The CLI will exitwithone ofthefollowing values:

  0Successful execution.

 1Failed executions.

创建data, export目录

[root@blockchain42ipfs]# mkdir data

[root@blockchain42ipfs]# mkdir export

设置ipfs_path

[root@blockchain42 ipfs]# export IPFS_PATH=/data/ipfs/data

初始化ipfs

root@blockchain42 ipfs]# ipfs init

togetstarted, enter:

    ipfs cat /ipfs/QmS4ustL54uo8FzR9455qaxZwuMiUhyvMcX9Ba8nUH4uVv/readme

修改配置文件

[root@blockchain42 data]# cd data

[root@blockchain42 data]# vimconfig

设置ipfs_staging 和 ipfs_data

[root@blockchain42 data1]# export ipfs_staging=/data/ipfs/export

[root@blockchain42 data1]# export ipfs_data=/data/ipfs/data 

docker 启动

[root@blockchain42 data1]# docker run -d --name ipfs_host --restart="always"--privileged=true -v $ipfs_staging:/export -v $ipfs_data:/data/ipfs -p4001:-p127.0.0.::-p5001:5001ipfs/go-ipfs:latest

修改链接ip

/ip4/10.19.0.40/tcp/4001/ipfs/QmUdmCCbmt5cQzPZST7U5ceaVdoCiHe2ZpxHopce5gFoXp 

添加peer

[root@blockchain42 ~]# docker exec ipfs_host ipfs swarm connect /ip4/10.19.0.40/tcp//ipfs/QmUdmCCbmt5cQzPZST7U5ceaVdoCiHe2ZpxHopce5gFoXp

测试

在一台上添加数据、另一台上去， 测试集群是否添加上
