root@ubuntu:~/soft/go-ipfs# ./install.sh
We cannot install ipfs in one of the directories /usr/local/bin /usr/bin
看到以上提示，不要理睬，ipfs help查看是否安装成功
http://localhost:5001/webui 可以打开页面，http://192.168.1.XX:5001/webui 无法打开页面
修改 /root/.ipfs/config
"API": "/ip4/127.0.0.1/tcp/5001" -->改为 "API": "/ip4/192.168.1.XX/tcp/5001" 重启服务
则可以打开页面
