这个问题的答案,网上乱七八糟的,整理一下:
# 1:Nux软件仓库依赖于EPEL软件仓库。启用EPEL存储库
sudo yum install epel-release
# 2:导入yum仓库GPG密钥,通过安装rpm软件包启用Nux存储库
sudo rpm -v --import http://li.nux.ro/download/nux/RPM-GPG-KEY-nux.ro
sudo rpm -Uvh http://li.nux.ro/download/nux/dextop/el7/x86_64/nux-dextop-release-0-5.el7.nux.noarch.rpm
# 3:安装exfat-fuse和exfat-utils
sudo yum install exfat-utils fuse-exfat
