1，IPFS ubuntu 搭建

• 系统环境

# lsb_release -a
No LSB modules are available.
Distributor ID:	Ubuntu
Description:	Ubuntu 18.04.3 LTS
Release:	18.04
Codename:	bionic

• go-ipfs 二进制包下载v0.4.22

# tar -zxvf go-ipfs_v0.4.22_linux-amd64.tar.gz
# cd go-ipfs/
# ./install.sh
Moved ./ipfs to /usr/local/bin

• 初始化存储库

# ipfs init

2，运行ipfs守护程序

# ipfs daemon
Initializing daemon...
go-ipfs version: 0.4.22-
Repo version: 7
System version: amd64/linux
Golang version: go1.12.7

Daemon is ready

• 查看连接节点

# ipfs swarm peers | wc -l
628

2.1，后台运行

• 后台运行命令

nohup ipfs daemon >> /storage/ipfs.log 2>&1 &

• 创建systemd服务，如果有设置环境变量添加变量Environment

# cd /lib/systemd/system/
# touch ipfs.service
# vim ipfs.service
[Unit]
Description=ipfs service
[Service]
Environment='IPFS_PATH=/storage/ipfs'

ExecStart=/usr/local/bin/ipfs daemon
Restart=always
User=root
Group=root
[Install]
WantedBy=multi-user.target
# systemctl daemon-reload
# systemctl enable ipfs.service
Created symlink from /etc/systemd/system/multi-user.target.wants/ipfs.service to /lib/systemd/system/ipfs.service.
# systemctl start ipfs.service
# systemctl status ipfs.service

• web访问

http://ip地址:5001/webui

3，下文件

# ipfs get /ipns/proofs.filecoin.io -o /V20/
Saving file(s) to /V20/
 2.00 MiB / 61.75 GiB [>-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------]   0.00% 5h16m55s

4，设置环境变量，改变ipfs目录

# vim /root/.bashrc
export IPFS_PATH=/storage/ipfs

# source /root/.bashrc

# echo $IPFS_PATH
/storage/ipfs

• 初始化

# which ipfs
/usr/local/bin/ipfs

# ipfs init
initializing IPFS node at /storage/ipfs

# pwd
/storage/ipfs
# ls
blocks  config  datastore  datastore_spec  keystore  version
